Answers
The perimeter of the triangle present in above figure is 42 dm. Then the value of x is equals to the 9 dm and all three sides of triangle are 9 dm, 11 dm and 22 dm.
We have a triangle present in above figure. The perimeter is the length of the boundaries of a shape. A triangle is a type of polygon with three sides. In other words, it is a closed two dimensional shape having three straight sides. So, perimeter of a triangle = sum of all three sides. Here, perimeter of triangle = 42 dm
Now, first side length of triangle= (3x - 5 ) dm
Second side length = (x + 2) dm
Third side length = x dm
Now, using perimeter formula for triangle,
=> 3x - 5 + x + x + 2 = 42
=> 5x = 42 + 5 - 2 = 45
=> x = 45/5 = 9
3x - 5 = 22 dm
x + 2 = 11 dm
So, sides of triangle are 9 dm, 11 dm and 22 dm.

(a) Consider the recursively defined set of binary strings B defined by: Basis Step: 0∈B,1∈B Recursive Step: if x∈B then xx∈B where xx is the string concatenated with itself. Prove using structural induction that for all elements x of B, the length of x is an integer power of 2 . (b) Recall the recursive definition of N. Basis Step: 0∈N Recursive Step: If m∈N then m+1∈N. Consider the function sumeven :N→N defined recursively as: Basis Step: sumeven (0)=0 Recursive Step: If m∈N then sumeven (m+1)=sumeven(m)+(2m+2) Use structural induction to show that for all n∈N, that sumeven (n)=n(n+1). (c) Consider the recursively defined set D of binary strings: Basis Step: 0∈D and 1∈D Recursive Step: If x∈D and w∈D then wxw∈D 1 Prove using structural induction that for all elements u∈D,u starts and ends with the same character.
Answers
Using structural induction, the length of all elements x of B is an integer power of 2, for all n∈N, sumeven(n) = n(n+1), for all elements u of D, u starts and ends with the same character.
What is the prove of all elements x of Ba) Basis Step: For the string 0, the length is 1 which is equal to 2^0, and for the string 1, the length is also 1 which is equal to 2^0. Hence, the property holds for the basis step.
Recursive Step: Assume that the length of the binary string x is an integer power of 2. Then, the length of xx is twice the length of x which is also an integer power of 2. Therefore, the length of xx is an integer power of 2. Hence, the property holds for the recursive step.
Therefore, by structural induction, the length of all elements x of B is an integer power of 2.
(b) Basis Step: For n = 0, sumeven(n) = 0 and n(n+1) = 0(0+1) = 0. Hence, the property holds for the basis step.
Recursive Step: Assume that for some n∈N, sumeven(n) = n(n+1). We need to show that sumeven(n+1) = (n+1)(n+2).
Using the recursive step of the definition of sumeven, we have:
sumeven(n+1) = sumeven(n) + (2(n+1)+2)
= n(n+1) + 2n + 4
= n^2 + 3n + 2
= (n+1)(n+2)
Hence, the property holds for the recursive step.
Therefore, by structural induction, for all n∈N, sumeven(n) = n(n+1).
(c) Basis Step: For the strings 0 and 1, the property holds since they start and end with the same character.
Recursive Step: Assume that for some strings u, v, and w, u and w start and end with the same character. We need to show that the string wxw also starts and ends with the same character.
Since u and w start and end with the same character, we can write u = axa and w = byb for some characters a, b, x, and y. Then, the string wxw can be written as axaybybaxa which starts and ends with the same character a.
Similarly, we can write u = axa and w = byb for some characters a, b, x, and y such that a ≠ b. Then, the string wxw can be written as axaybybaxa which starts and ends with the same character a.
Therefore, by structural induction, for all elements u of D, u starts and ends with the same character.

Answers
Answer:
£756
Step-by-step explanation:
To fill the tank completely, Mr. Patel needed:
500 liters initially + (total capacity of the tank - 500 liters) = 500 + (tank capacity - 500) = tank capacity
To find the tank capacity, we need to know how many liters of oil Mr. Patel bought initially:
Total cost of oil bought initially = 900
Cost per liter of oil = £0.60
Number of liters of oil bought initially = 900 / 0.60 = 1500
Therefore, the tank capacity is:
500 + (tank capacity - 500) = 1500
Tank capacity - 500 = 1000
Tank capacity = 1500 liters
At the beginning of February, Mr. Patel had 300 liters of oil left in his tank, so he needed to buy:
1500 - 300 = 1200 liters of oil
The cost of oil had increased by 5%, so the cost per liter was:
£0.60 + (£0.60 x 0.05) = £0.63
Therefore, the total cost of the oil in February was:
1200 x £0.63 = £756

Step-by-step explanation:
Which statement best compares and contrasts the two formats?
The infographic shows the movement of water visually, while the text describes it.
The infographic would be less appealing to visual learners than the text.
It is impossible to understand the infographic without the text.
The text is more accurate than the infographic.
The probability that the second interview will be given to a woman, given that the first interview was given to another woman is 18/323 and the probability of all three interviews being given to men is: (9/22) * (8/21) * (7/20) = 21/770
To find the probability that the second interview will be given to a woman, given that the first interview was given to another woman, we can use conditional probability. Let’s call the event that the first interview was given to a woman A, and the event that the second interview is given to a woman B.
Then we want to find P(B|A), the probability of B given A. Using a tree diagram, we can see that the probability of A is:(13/22) * (12/21) = 4/11The probability of B given A is: (9/20) * (8/19) = 18/323. Therefore, the probability that the second interview will be given to a woman, given that the first interview was given to another woman, is 18/323.(b) To find the probability that all three interviews will be given to men, we can use the multiplication rule of probability.
The probability of selecting a man on the first interview is 9/22. The probability of selecting a man on the second interview, given that the first interview was given to a man, is 8/21. The probability of selecting a man on the third interview, given that the first two interviews were given to men, is 7/20. So, the probability of all three interviews being given to men is:(9/22) * (8/21) * (7/20) = 21/770

7. Researchers at the University of North Carolina are studying the spread of diseases. For a new bacterial
disease, they are able to isolate one cell, and they watch as it divides into three cells over the first hour.
The number of cells grows exponentially until there are 35 cells after 5 hours. The researchers are nervous
about the constant growth, and they keep watching the bacteria grow. Over the next 4 hours, the number of
cells continues to grow, multiplying the previous total by 3¹.
Express the total number of cells after 9 hours first as an exponential expression and then as a whole
number.
Answers
The total number of cells after 9 hours is approximately 10671.
What is an exponential expression?An exponential expression is a mathematical expression in which a number or variable is raised to a power, which is usually written as a superscript. The base is the number or variable being raised to a power, and the exponent is the number indicating how many times the base is multiplied by itself.
In the given question,
The initial growth of the bacterial cells can be modeled by an exponential function of the form:
N(t) = N0 * 3^(kt)
Where N(t) is the number of cells at time t, N0 is the initial number of cells, k is the growth rate, and t is the time elapsed.
Using the information given in the problem, we can find N0 and k as follows:
N0 = 1 (since the researchers started with one cell)
N(5) = 35
N(5) = N0 * 3^(5k) = 35
3^(5k) = 35
5k = log3(35)
k = log3(35)/5
Therefore, the function for the growth of bacterial cells is:
N(t) = 3^(t*log3(35)/5)
To find the total number of cells after 9 hours, we can substitute t=9 into the equation:
N(9) = 3^(9*log3(35)/5) ≈ 10671
Therefore, the total number of cells after 9 hours is approximately 10671.

Mr Irfan wants to use tiles of length 20 cm and breadth 10 cm to cover
Answers
Mrs. Irfan needs to buy 10,000 tiles to cover the floor of her balcony.
To determine the number of tiles Mrs. Irfan needs to cover her balcony, we need to first calculate the area of each tile. The area of each tile can be determined by multiplying its length and breadth:
Area of each tile = Length × Breadth = 20 cm × 10 cm = 200 cm²
Next, we need to calculate the total area of the balcony, which is given as 200 cm². However, we need to convert this to square centimeters since we have determined the area of each tile in square centimeters. We can do this by multiplying 200 cm² by 10,000 (1 square meter is equal to 10,000 square centimeters):
Total area of balcony in square centimeters = 200 cm² × 10,000 = 2,000,000 cm²
To determine the number of tiles Mrs. Irfan needs, we can divide the total area of the balcony by the area of each tile:

Apply Newton's Method to approximate the x-value(s) of the indicated point(s) of intersection of the two graphs. Continue the iterations until two successive approximations differ by less than 0.001. [Hint: Let h(x) = f(x) − g(x).] (Round your answer to four decimal places.)
f(x) = x^6
g(x) = cos(x)
Answers
Answer:
Using Newton's Method, the points of intersection between f(x) = x^6 and g(x) = cos(x) are approximately (0.8241, f(0.8241)) and (2.3111, f(2.3111)), where f(x) = x^6.
To find the points of intersection of the graphs of f(x) = x^6 and g(x) = cos(x), we can solve the equation h(x) = f(x) - g(x) = x^6 - cos(x) = 0.
Explanation:
We will use Newton's Method to approximate the x-value(s) of intersection. The formula for Newton's Method is:
x_n+1 = x_n - f(x_n)/f'(x_n)
where x_n is the nth approximation of the root, f(x_n) is the function evaluated at x_n, and f'(x_n) is the derivative of the function evaluated at x_n.
Let h(x) = x^6 - cos(x), then
h'(x) = 6x^5 + sin(x)
Now we need to choose a starting value for x. By graphing the two functions, we can see that there are two points of intersection in the interval [0,1]. Let's choose x = 0.5 as our starting value.
x_0 = 0.5
x_1 = x_0 - h(x_0)/h'(x_0) = 0.5352
x_2 = x_1 - h(x_1)/h'(x_1) = 0.8656
x_3 = x_2 - h(x_2)/h'(x_2) = 0.8249
x_4 = x_3 - h(x_3)/h'(x_3) = 0.8241
Thus, the approximate value of the first intersection point is x = 0.8241.
Now we need to find the second intersection point. By graphing the two functions, we can see that there is another intersection point in the interval [2,3]. Let's choose x = 2.5 as our starting value.
x_0 = 2.5
x_1 = x_0 - h(x_0)/h'(x_0) = 2.3214
x_2 = x_1 - h(x_1)/h'(x_1) = 2.3111
x_3 = x_2 - h(x_2)/h'(x_2) = 2.3111
Thus, the approximate value of the second intersection point is x = 2.3111.
Therefore, the points of intersection of the two graphs are approximately (0.8241, f(0.8241)) and (2.3111, f(2.3111)), where f(x) = x^6.

the average age of trees in a large park is 60 years with a standard deviation of 2.2 years. a simple random sample of 400 trees is selected, and the sample mean age of these trees is computed. what is the standardized value that corresponds to ?
Answers
The standard value that corresponds to a sample mean age of 60 years is 0.
We can use the formula for the z-score (standardized value) to find the answer:
z = (x - μ) / (σ / sqrt(n))
where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.
In this case, we have:
x = sample mean age of the 400 trees
μ = population mean age of trees in the large park = 60 years
σ = population standard deviation of tree ages in the large park = 2.2 years
n = sample size = 400
We don't know the value of x, but we do know that the distribution of sample means is approximately normal, with a mean of μ = 60 and a standard deviation of σ / sqrt(n) = 2.2 / sqrt(400) = 0.11.
So, we want to find the standardized value for a sample mean that is 0 standard deviations away from the population mean, which means:
z = (x - 60) / 0.11 = 0
Solving for x, we get:
x - 60 = 0
x = 60
Therefore, the standardized value that corresponds to a sample mean age of 60 years is:
z = (x - μ) / (σ / sqrt(n))
z = (60 - 60) / 0.11
z = 0
So the answer is 0.

The point where the equation of the line touch the circle is (2.166, 3.083).
and
Where does the equation of the line touch the circle in the first quadrantThe equation of a circle with center (h, k) and radius r is:
(x - h)^2 + (y - k)^2 = r^2
So the equation of the circle with center (0, 2) and radius 5 is:
x^2 + (y - 2)^2 = 25
We can solve for the intersection of the circle and the line y = 0.5x + 2 by substituting y = 0.5x + 2 into the equation of the circle:
x^2 + (0.5x)^2 + 2x + 2^2 - 25 = 0
Simplifying and solving for x:
1.25x^2 + 2x - 9 = 0
Using the quadratic formula, we get:
x = (-2 ± √(2^2 - 41.25(-9))) / (2*1.25)
x = (-2 ± √(104)) / 2.5
x ≈ -6.166 or x ≈ 2.166
Since we are looking for a point in the first quadrant, we take the positive value of x:
x ≈ 2.166
Now we can use the equation of the line to find the corresponding y-coordinate:
y = 0.5x + 2
y ≈ 3.083
Therefore, the point where the line y = 0.5x + 2 intersects the circle with radius 5 and center (0, 2) in the first quadrant is approximately (2.166, 3.083).

10 points 6) Find all the zeros of \( f(x)=x^{3}-3 x^{2}+4 x-2 \) and write \( f(x) \) in factored form 10 points
Answers
To find all the zeros of the function f(x) = x^3 - 3x^2 + 4x - 2 and write f(x) in factored form, we can use the Rational Root Theorem.
What is the Rational Root Theorem?
If we have a polynomial with integer coefficients, we can use the Rational Root Theorem to find all of the possible rational roots (solutions) of the polynomial. The Rational Root Theorem says that if a polynomial has a rational root p/q (where p and q are integers), then p must be a factor of the constant term of the polynomial (the term without x), and q must be a factor of the leading coefficient of the polynomial (the coefficient of the highest power of x).
To apply the Rational Root Theorem to the function f(x) = x^3 - 3x^2 + 4x - 2, we look at the constant term (-2) and the leading coefficient (1) of the polynomial to find all of the possible rational roots. The possible rational roots are: ±1, ±2.
First, let's try x = 1 as a possible root. We can use synthetic division to see if it's a zero:
1 | 1 -3 4 -2
| 1 -2 2
|__________
1 -2 6 0
There is no remainder, so x = 1 is a zero of the function. Now, we can use synthetic division again to factor out (x - 1):
(x - 1)(x^2 - 2x + 6)
To find the remaining zeros, we can solve the quadratic equation x^2 - 2x + 6 = 0 using the quadratic formula:
x = (2 ± √(2^2 - 4(1)(6))) / (2(1))
x = (2 ± √(-20)) / 2
x = 1 ± i√5
The zeros of f(x) are:
x = 1, x = 1 + i√5, x = 1 - i√5
So, we can write f(x) in factored form as:
f(x) = (x - 1)(x - (1 + i√5))(x - (1 - i√5))

In conclusion, when looking at the relationship between the average price of a barrel of oil and the average retail price of a gallon of unleaded regular gasoline, you should expect to see a weak negative association between the two variables. However, there will also be some degree of variability in the relationship due to other factors that affect the price of gasoline.
The best way to see how well the price of oil predicts the price of gasoline is to make a scatterplot with the price of oil as the explanatory variable. The scatterplot will show the relationship between the average price of a barrel of oil and the average retail price of a gallon of unleaded regular gasoline.
When examining the scatterplot, you should expect to see a weak negative association between the two variables. This means that when the price of oil increases, the price of gasoline will tend to decrease. This is because when the price of oil goes up, the production costs of gasoline also go up, which in turn causes the retail price of gasoline to increase.
The scatterplot should also indicate that there is a certain degree of variability in the relationship between the two variables. This is because the price of gasoline is also affected by other factors, such as taxes, supply and demand, weather conditions, and availability of other fuels.
Therefore, while the price of oil is a good indicator of the price of gasoline, the relationship between the two is not always exact.

To find the quotient of 3/4 divided by 3/8, we can use the rule that dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of 3/8 is 8/3, so we have:
3/4 ÷ 3/8 = 3/4 × 8/3
To simplify this expression, we can cancel out a factor of 4 from the numerator and denominator of 3/4, and a factor of 3 from the numerator and denominator of 8/3. This gives us:
3/4 × 8/3 = (3 × 2)/(1 × 1) = 6
Therefore, the quotient of 3/4 divided by 3/8 is 6.

Answers
Bill's earnings are subject to deductions for Social Security, Medicare, and Federal Income Tax (FIT). Today, Bill's cumulative earnings are $110,000. This week, Bill earned $1,200. As Bill is married, is paid weekly, and claims three exemptions, the Social Security rate is 6.2% of $128,401.45, and the Medicare rate is 1.45%. Bill will not pay FIT for the week.
To calculate Bill's earnings for the week, we first subtract the applicable deductions from his $1,200 gross earnings. The Social Security rate of 6.2% on $128,401.45 is $7,966.98, and the Medicare rate of 1.45% is $181.80. This means that $9,148.78 is deducted from Bill's $1,200 gross earnings, leaving him with a net earnings of $286.22.
To calculate Bill's total cumulative earnings, we need to add the $1,200 that he earned this week to his existing $110,000 cumulative earnings. Thus, Bill's total cumulative earnings are $111,200.

find the measure of side b
Answers
The measure of side AC is approximately 366.9 inches.
Describe Triangle?A triangle is a geometric shape that consists of three straight sides and three angles. It is one of the basic shapes in geometry and is often studied as a fundamental building block in mathematics, engineering, and physics. Triangles have several important properties, including:
The sum of the angles in a triangle is always 180 degrees.
The longest side of a triangle is opposite to the largest angle, and the shortest side is opposite to the smallest angle.
The area of a triangle can be calculated using the formula: area = 1/2 x base x height, where the base is one of the sides and the height is the perpendicular distance from the base to the opposite vertex.
Triangles can be classified based on the length of their sides and the measure of their angles. For example, a triangle with all three sides of equal length is called an equilateral triangle, while a triangle with two sides of equal length is called an isosceles triangle.
To find the measure of side AC, which is denoted by "b", we can use the Law of Cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles. Specifically, the Law of Cosines states that:
c² = a² + b² - 2ab cos(C)
where "a" and "b" are the lengths of the other two sides of the triangle, and "C" is the angle opposite to side "c".
In this case, we know that side AB has length "c" (290 inches), and side AC is denoted by "b". We also know that the angle opposite to side AB has measure 42 degrees. Therefore, we can write:
c² = a² + b² - 2ab cos(C)
290² = a² + b² - 2ab cos(42)
Simplifying this equation and solving for b, we get:
b² - 2ab cos(42) + (290² - a²) = 0
This is a quadratic equation in "b", which we can solve using the quadratic formula:
b = [2a cos(42) ± √((2a cos(42))² - 4(290² - a²)]/2
Simplifying this expression, we get:
b = a cos(42) ± √(a² cos²(42) - (290² - a²))
We don't know the value of "a", so we cannot find the exact value of "b". However, we can use the fact that "b" is a length of a triangle, so it must be positive. Therefore, we can discard the negative square root, and we get:
b = a cos(42) + sqrt(a² cos²(42) - (290² - a²))
Since "b" is positive, we can set the expression inside the square root to zero and solve for "a":
a² cos²(42) - (290² - a²) = 0
Simplifying and solving for "a", we get:
a = 290/sin(42)
Substituting this value of "a" back into the equation for "b", we get:
b = (290/sin(42)) cos(42) + sqrt((290/sin(42))² cos²(42) - 290² + (290/sin(42))²)
Simplifying this expression, we get:
b ≈ 366.9 inches
Therefore, the measure of side AC is approximately 366.9 inches.

1. Net income after deductions: $1,880.00 - $487.48 = $1,392.52. 2. your total realized income for that month would be $2,574.00. 3. the total income for the second month would be $2,574.00 + $822.50 = $3,396.50.
Describe income ?Income refers to the money earned or received by an individual or an entity in exchange for goods or services provided or as compensation for work done. It can come from various sources such as employment, investments, rental properties, or business activities. Income is often used to pay for expenses, such as bills, food, housing, transportation, and other necessities. It is also commonly saved or invested to build wealth and achieve long-term financial goals.
1. Assuming a month has 4 weeks, your total realized income for one month would be:
40 hours/week x $11.75/hour x 4 weeks = $1,880.00
Your fixed expenses for one month would be:
Rent: $657.00
Telephone: $56.34
Groceries: $56.00 x 4 = $224.00
Clothing: $106.00
Water & Electric: $98.87
Total fixed expenses: $1,142.21
Your discretionary expenses for one month would be:
Weekly Dinner & Movie: $40.00 x 4 = $160.00
Total discretionary expenses: $160.00
Therefore, your total expenses for one month would be:
Fixed expenses + discretionary expenses = $1,142.21 + $160.00 = $1,302.21
To calculate your net income after deductions, we need to first calculate the amount of deductions:
FICA: 7.65% of $1,880.00 = $143.88
Federal tax withholding: 10.75% of $1,880.00 = $202.60
State tax withholding: 7.5% of $1,880.00 = $141.00
Total deductions: $487.48
Net income after deductions: $1,880.00 - $487.48 = $1,392.52
2. If you work 20 hours of overtime the next month and are paid 1.5 times your regular rate, your total realized income for that month would be:
(40 hours x $11.75/hour x 4 weeks) + (20 hours x $11.75/hour x 1.5 x 4 weeks) = $2,574.00
Your fixed expenses would remain the same, but your discretionary expenses may increase due to the additional income.
3. If you eliminated your discretionary expenses of $160.00 per month, you could put that amount towards savings each month. This would increase your savings by $1,920.00 per year.
To calculate the income for the first 40 hours of work, we simply multiply the hourly rate by the number of hours worked:
40 hours x $11.75/hour = $470.00
To calculate the income for the additional 20 hours of overtime at 1.5 times the regular rate, we first calculate the regular rate for the overtime hours (40 hours x $11.75/hour = $470.00), and then add 1.5 times that amount to the total:
40 hours x $11.75/hour = $470.00
20 hours x ($11.75/hour x 1.5) = $352.50
Total overtime pay = $470.00 + $352.50 = $822.50
Therefore, the total income for the second month would be $2,574.00 + $822.50 = $3,396.50.

Follow-Up: Now let’s define an interesting number as a 10-digit number divisible by 11,111 with DISTINCT digits. How many interesting numbers are there?
Answers
Answer:
5,040
Step-by-step explanation:
There are a total of 5,040 interesting numbers, which can be calculated using basic combinatorics. To calculate this, the first step is to count the total number of 10-digit numbers with distinct digits. Since there are 10 distinct digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9), there are 10! (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) possible numbers with distinct digits. The next step is to count the number of 10-digit numbers divisible by 11,111. To do this, we need to find the number of 10-digit numbers divisible by 11. Since 11 is a prime number, there are 11 possible combinations of 10-digit numbers divisible by 11. For example, 0XXXXXXXXX, 1XXXXXXXXX, 2XXXXXXXXX, etc. So, there are 11 x 10! (110,000) possible 10-digit numbers divisible by 11. Finally, to find the number of interesting numbers, we need to subtract the number of 10-digit numbers divisible by 11,111 from the total number of 10-digit numbers with distinct digits. This gives us 10! - 11 x 10! = 5,040. Therefore, there are a total of 5,040 interesting numbers.
Answer:
To find the number of interesting numbers, we need to find the number of 10-digit numbers that are divisible by 11,111 and have distinct digits.
A number is divisible by 11,111 if and only if the alternating sum of its digits is divisible by 11. For example, 27,183,642 is divisible by 11,111 because 2 - 7 + 1 - 8 + 3 - 6 + 4 - 2 = -3, which is divisible by 11.
Since we want the number to have distinct digits, we can choose any 5 digits from the set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} and arrange them in any order. There are 10 choices for the first digit, 9 choices for the second digit (since we can't repeat the first digit), 8 choices for the third digit, and so on, giving us a total of 10 x 9 x 8 x 7 x 6 = 30,240 possible 5-digit numbers with distinct digits.
To form a 10-digit number, we can repeat the 5 digits in any order. There are 5! = 120 ways to arrange the 5 digits, so there are 120 different 10-digit numbers that can be formed from each 5-digit number.
Therefore, the total number of interesting numbers is:
30,240 x 120 = 3,628,800
So there are 3,628,800 interesting numbers that are 10-digit numbers divisible by 11,111 with distinct digits.

Six hours and 2 minutes later, the high tide occurred with a water depth of 6.82 feet. Find all components needed to write a model for this scenario since the first low tide. Find the water depth at 10:10am
Answers
Water depth at 10:10 am is approximately 4.34 feet.
Given data:The low tide occurred at 5:40 am with a water depth of 1.25 feet. Six hours and 2 minutes later, the high tide occurred with a water depth of 6.82 feet.Tide is the periodic rise and fall of sea level due to the gravitational pull of the Moon and the Sun on the Earth. This motion can be modeled by sinusoidal functions.The general form of the sine function is given as f(x) = a sin bx + c, where a is the amplitude, b is the period, and c is the vertical shift.To find all components needed to write a model for this scenario since the first low tide:First, we need to calculate the amplitude and period of the sine wave, as follows:Given that the low tide occurred at 5:40 am with a water depth of 1.25 feet.Similarly, the high tide occurred with a water depth of 6.82 feet at 11:42 am, which is 6 hours and 2 minutes after the low tide. Therefore, the period of the wave is 12 hours and 4 minutes or 12.067 hours.Amplitude is given as half the difference between the maximum and minimum values of the wave, which is 2.285 feet.Writing the model for the scenario since the first low tide is given as:f(x) = 2.285 sin ((2π/12.067) x) + cSince the water depth at low tide is 1.25 feet, the vertical shift is given as 3.065 feet.f(x) = 2.285 sin ((2π/12.067) x) + 3.065Now, we need to find the water depth at 10:10 am.To do that, we substitute x = 4.5 (since 5:40 am to 10:10 am is a period of 4.5 hours) in the above equation, and we get:f(4.5) = 2.285 sin ((2π/12.067) × 4.5) + 3.065≈ 4.34 feetTherefore, the water depth at 10:10 am is approximately 4.34 feet.
