Determine algebraically the dimensions, in feet, of the garden.

Answers

Answer 1

Answer:

Width: w = 12.5 feet

Length: L = 32.5 feet

Step-by-step explanation:

Let's use two variables to represent the dimensions of the rectangular garden:

Let w be the width of the garden (in feet)

Let L be the length of the garden (in feet)

The problem tells us that the length of the fence is 90 feet, so we can write the equation:

2L + 2w = 90

We also know that the length of the fence (L) is 5 feet less than 3 times the width (w). We can write this as another equation:

L = 3w - 5

Now we have two equations with two variables. We can solve this system of equations using substitution or elimination.

Let's use substitution:

Substitute the expression for L in terms of w from the second equation into the first equation:

2(3w - 5) + 2w = 90

Simplify and solve for w:

6w - 10 + 2w = 90

8w = 100

w = 12.5

Now we can use this value of w to find L:

L = 3w - 5 = 3(12.5) - 5 = 32.5

Therefore, the dimensions of the rectangular garden are as follows:

Width: w = 12.5 feet

Length: L = 32.5 feet

5.4 Claim severity per period is distributed as \( \mathcal{B N}(4,0.2) \). Calculate the probability of ruin at or before time 3 if the initial surplus is 3 .

Answers

The probability of ruin at or before time 3 with initial surplus 3 is 0.6915

The probability of ruin at or before time 3 with initial surplus 3, given the claim severity per period follows a binomial normal distribution with mean 4 and standard deviation 0.2, is calculated as follows:

Determine the z-score from the normal distribution corresponding to a surplus of 3 and a mean of 4.

z-score = (3-4)/0.2 = -0.5

Hence, the z-score result is -0.5



The next step is to use the cumulative probability density function to calculate the probability of ruin.

Probability of ruin = 1 - CDF(-0.5) = 1 - 0.3085 = 0.6915


Therefore, the probability of ruin at or before time 3 with initial surplus 3 is 0.6915.

What is one method to find the measure of angle b?

Answers

Angle B is 50 degrees in measurement.

One method to find the measure of angle b is to use the properties of angles in a triangle. We know that the sum of the angles in a triangle is 180 degrees. We also know that angles a and c have measures of 50 degrees and 80 degrees respectively. Therefore, we can find the measure of angle b by subtracting the sum of angles a and c from 180 degrees:

angle b = 180 degrees - angle a - angle c

angle b = 180 degrees - 50 degrees - 80 degrees

angle b = 50 degrees

Therefore, angle b has a measure of 50 degrees. Another method to find the measure of angle b is to use trigonometry, such as the sine or cosine rule, depending on the given information.

To solve for x and y, we can use either substitution or elimination method. Let's use the elimination method by multiplying the second equation by 8 and subtracting it from the first equation.

What is the equations based on the information?

1. Let x be the price of one senior citizen ticket and y be the price of one student ticket. We can set up two equations based on the information given:

4x + 5y = 102

7x + 5y = 126

We can solve for x and y using elimination or substitution. Here is one way to do it using elimination:

Multiply the first equation by -1 to get:

-4x - 5y = -102

Add this equation to the second equation to eliminate y:

3x = 24

Solve for x:

x = 8

Substitute x = 8 into one of the original equations to solve for y:

4(8) + 5y = 102

32 + 5y = 102

5y = 70

y = 14

Therefore, the price of one senior citizen ticket is S8 and the price of one student ticket is S14.

2. Let x be the speed of the plane in still air and y be the speed of the wind. We can set up two equations based on the information given:

x + y = 183

x - y = 141

We can solve for x and y using elimination or substitution. Here is one way to do it using addition:

Add the two equations to eliminate y:

2x = 324

Solve for x:

x = 162

Substitute x = 162 into one of the original equations to solve for y:

162 + y = 183

y = 21

Therefore, the speed of the plane in still air is 162 km/h and the speed of the wind is 21 km/h.

3. Let x be the cost of one apple pie and y be the cost of one lemon meringue pie. We can set up two equations based on the information given:

6x + 5y = 94

We can solve for x and y using elimination or substitution. Here is one way to do it using subtraction:

Subtract the second equation from the first equation to eliminate x:

y = 116

Substitute y = 116 into one of the original equations to solve for x:

[tex]6x + 4(116) = 580[/tex]

6x = 16

[tex]x = 8/3 or 2.67[/tex]

Therefore, the cost of one apple pie is S2.67 and the cost of one lemon meringue pie is S116.

4. Let's assume the price of one senior citizen ticket is "S" and the price of one child ticket is "C".

From the given information, we can form two equations:

[tex]3S + 3C = 569[/tex]  ...(1) (sales on the first day)

[tex]5S + 3C = 981[/tex] ...(2) (sales on the second day)

To solve for S and C, we can use any method of solving linear equations (substitution, elimination, or matrix method). Here, we will use the substitution method.

From equation (1), we can express C in terms of S:

C = (569 - 3S)/3

Substituting this value of C in equation (2), we get:

[tex]5S + 3[(569 - 3S)/3] = 981[/tex]

Solving for S:

[tex]5S + 569 - 9S = 2943[/tex]

[tex]-4S = -2374[/tex]

[tex]S = 593.5[/tex]

Therefore, the price of one senior citizen ticket is  [tex]S593.5[/tex]  .

To find the price of one child ticket, we can substitute this value of S in equation (1) and solve for C:

[tex]3(593.5) + 3C = 569[/tex]

[tex]3C = -1518.5[/tex]

[tex]C = -506[/tex]

y = 89

Now we can substitute y = 89 into either equation to solve for x. Let's use the second equation:

[tex]x + 4(89) = 893[/tex]

[tex]x = 529[/tex]

Therefore, the cost of one package of chocolate chip cookie dough is $529, and the cost of one package of gingerbread cookie dough is $89.

[tex]12x + 12y = 2160[/tex] (second day sales)

To solve for x and y, we can use either substitution or elimination method. Let's use the elimination method by multiplying the first equation by 4 and subtracting it from the second equation:

[tex]12x + 12y = 2160[/tex]

[tex]-12x - 20y = -2280[/tex]

[tex]-8y = -120[/tex]

y = 15

A boat travels at a speed of 20 miles per hour in still water. It travels 48 miles upstream, and then returns to the starting point in a total of five hours. What is the speed of the current (in miles per hour.)?

Answers

The speed of the current is approximately 39.05 miles per hour.

How is distance calculated?

Distance equals rate times time in the equation for distance, rate, and time. This equation shows how far an item moves over a specific amount of time at a specific pace by relating the three variables in a linear equation. Any of the three variables can be solved for by rearranging the formula.

Let us suppose the speed of current = c.

Then the formula for distance is given as:

distance = rate x time

For upstream:

distance = 48 miles

rate = 20 - c miles per hour

time = distance / rate

= 48 / (20 - c) hours

For downstream:

distance = 48 miles

rate = 20 + c

time = distance / rate

= 48 / (20 + c) hours

The total time for the trip is 5 hours thus,

48 / (20 - c) + 48 / (20 + c) = 5

Taking the LCM:

48(20 + c) + 48(20 - c) = 5(20 - c)(20 + c)

1920 = 400 - c²

c² = 1520

c ≈ 39.05 miles per hour

Hence, the speed of the current is approximately 39.05 miles per hour.

The logarithm that is equal to the number of years it will take for the population to increase to 15,000 students is log(11.08).

Let t be the number of years it will take for the enrollment to increase to 15,000 students. We can use the formula for continuous growth to set up an equation:

[tex]A = Pe^{(rt)[/tex]

where A is the final amount, P is the initial amount, r is the annual growth rate as a decimal, and t is the time in years.

In this case, we know that P = 12,000, A = 15,000, and r = 0.025 (since the growth rate is 2.5%). Plugging these values into the equation, we get:

[tex]15,000 = 12,000 e^{(0.025t)[/tex]

Dividing both sides by 12,000, we get:

To solve for t, we can take the natural logarithm of both sides:

[tex]ln(1.25) = ln(e^{(0.025t))[/tex]

Using the property of logarithms that [tex]ln(e^x) = x[/tex], we can simplify the right-hand side:

How much was the price of the meal?(Round to the nearest cent)

Answers

Step-by-step explanation:

We can start by assuming that the price of the meal is x dollars. Then, we know that:

15% of x is equal to $4.89

18% of x is equal to $5.87

20% of x is equal to $6.52

We can set up three equations using these statements:

0.15x = 4.89

0.18x = 5.87

0.20x = 6.52

Solving for x in each equation, we get:

x = 4.89 / 0.15 = 32.60

x = 5.87 / 0.18 = 32.61

x = 6.52 / 0.20 = 32.60

Since all three equations give us a value of x that is very close to 32.60, we can assume that the price of the meal was $32.60, rounded to the nearest cent.

Substituting this into the expression above, we get: [tex][\frac{x^{2}+2hx+h^{2}-1-x^{2}+1}{h}\][/tex], Simplifying the expression, we can cancel out the [tex]\(x^{2}\)[/tex] terms, and the [tex](1\)s:\[\frac{2hx+h^{2}}{h}\][/tex]

Next, we can factor out the \(h\) from the numerator: [tex]\[h\cdot\frac{2x+h}{h}\][/tex].

Cancelling out the [tex]\(h\)s[/tex], we get:[tex]\[2x+h\][/tex] ,Therefore, the difference quotient of the function [tex]\(f(x)=x^{2}-1\) is \(2x+h\)[/tex], where [tex]\(h\)[/tex] is the small change in [tex]\(x\)[/tex].

The area of a rectangle is 195 dm². The width is two less than the length. What is the length and the width of tge rectangle?

Answers

The length of the rectangle is 15 dm and the width is 13 dm.

Let's assume that the length of the rectangle is "L" and the width is "W".

From the problem statement, we have two pieces of information:

The area of the rectangle is 195 dm²:

Area = Length x Width

195 dm² = L x W

The width is two less than the length:

W = L - 2

Now, we can substitute the second equation into the first equation to eliminate W and get an equation with only one variable:

195 dm² = L x (L - 2)

Simplifying the equation:

195 dm² = L² - 2L

L² - 2L - 195 dm² = 0

To solve for L, we can use the quadratic formula:

L = (-b ± √(b² - 4ac)) / 2a

Where a = 1, b = -2, and c = -195.

L = (2 ± √(2² + 4 x 1 x 195)) / 2 x 1

L = (2 ± √4 + 780) / 2

L = (2 ± √784) / 2

L = (2 ± 28) / 2

L = 15 or L = -13

Since the length can't be negative, the length of the rectangle is L = 15 dm.

Now we can use the equation W = L - 2 to find the width:

W = 15 dm - 2 dm

W = 13 dm

Therefore, the length of the rectangle is 15 dm and the width is 13 dm.

1.

In other words, if you hit the inverse tangent button for 2/3 on your calculator, will it give you the angle we are looking for? Briefly explain. d) Find the approximate value of the angle, rounded to the nearest whole degree. e) Write an expression for all coterminal angles to your answer to part d, in radians.

Answers

a) cos  φ= -4/13`

b) cos φ  -2√13/13`c)

c) inverse tangent function will not give us the angle we are looking for because our angle is in the third quadrant

d) tanφ=32​ => φ ≈ -57.99°

e) coterminal angles to -57.99° in radians is:`(-319.93 + 360n)π/180`, where `n` is an integer.

a) The formula for the tangent of an angle in the third quadrant is, `tan(π + φ) = tan φ` and, hence, we have:`tan(π + φ) = 3/2`Using the fundamental identity for the tangent, we get:`tan(π + φ) = -tan φ``tan φ = -3/2`Then, using the Pythagorean identity `sin^2 φ + cos^2 φ = 1` to solve for `cos φ` in the third quadrant where `cos φ < 0`, we get:`cos φ = -√(1 - sin^2 φ) = -√(1 - (tan^2 φ)/(1 + tan^2 φ)) = -√(1 - (9/13)) = -4/13`b) Since `tan φ = 3/2`, we can construct a right triangle with legs of length `3` and `2` and hypotenuse of length `√(3^2 + 2^2) = √13`.Since the angle is in the third quadrant, the cosine of the angle is negative. Thus:`cos φ = -2/√13 = (-2/√13) * (√13/√13) = -2√13/13`c) The inverse tangent function is only able to give you the value of the angle in the first or fourth quadrant. Therefore, using the inverse tangent function will not give us the angle we are looking for because our angle is in the third quadrant.d) `tanφ=32​ => φ ≈ -57.99°`e) All coterminal angles to -57.99° in radians are given by:`θ = -57.99° + 360n, n ∈ ℤ`Thus, we can convert to radians using the formula `π/180°`:`θ = (-57.99° + 360n)π/180°`Simplifying:`θ = (-319.93 + 360n)π/180`Therefore, the expression for all coterminal angles to -57.99° in radians is:`(-319.93 + 360n)π/180`, where `n` is an integer.

AB is diameter of a circle whose center is at (1,1) , if A is at (-3,3), what are the coordinates of B

Answers

The coordinates of B of the diameter of the circle is: (5, -1).

How to Find the Coordinates of the Endpoints of the Diameter of a Circle?

Since AB is a diameter of the circle, its midpoint will be the center of the circle, which is given to be (1, 1). Therefore, we can find the coordinates of point B by using the midpoint formula.

Midpoint formula:

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2).

Let A be (-3, 3), which is one endpoint of the diameter AB. Let B be the other endpoint of the diameter AB.

Since the midpoint of AB is (1, 1), we have:

((x-coordinate of A + x-coordinate of B)/2, (y-coordinate of A + y-coordinate of B)/2) = (1, 1)

Substituting the coordinates of point A, we get:

((-3 + x-coordinate of B)/2, (3 + y-coordinate of B)/2) = (1, 1)

Multiplying both sides of each equation by 2, we get:

(-3 + x-coordinate of B, 3 + y-coordinate of B) = (2, 2)

Adding 3 to both sides of the first equation and subtracting 3 from both sides of the second equation, we get:

(x-coordinate of B, y-coordinate of B) = (2+3, 2-3) = (5, -1)

Therefore, the coordinates of point B are (5, -1).

Marques wants to use a sheet of fiberboard 36 inches long to create a skateboard ramp with a 30 degree angle of elevation from the ground. How high will the ramp rise from the ground at its highest end? Round your answer to the nearest tenth of an inch if necessary.

Answers

The ramp will rise 18 inches from the ground at its highest end.

To determine the height of the ramp at its highest end, we can use trigonometry and the given angle of elevation.

In a right triangle formed by the ramp, the ground, and the height of the ramp, the angle of elevation (30 degrees) is the angle between the ground and the hypotenuse (the ramp itself). The height of the ramp is the opposite side, and the length of the ramp is the hypotenuse.

Using the trigonometric function sine (sin), we can set up the equation:

sin(30 degrees) = opposite/hypotenuse

sin(30 degrees) = height/36 inches

Since the sine of 30 degrees is 0.5:

0.5 = height/36 inches

To solve for the height, we can multiply both sides of the equation by 36:

0.5 x 36 inches = height

18 inches = height
