In response to the question, we may say that  Hence, 2 131/200 is the decimal mixed number in its most basic form.

The decimal number system is frequently used to express both integer and non-integer quantities. Non-integer values have been added to the Hindu-Arabic numeral system. The technique used to represent numbers in the decimal system is known as decimal notation. A decimal number consists of both a whole number and a fractional number. The numerical value of complete and partially whole quantities is expressed using decimal numbers, which are in between integers. The full number and the fractional part of a decimal number are separated by a decimal point. The decimal point is the little dot that appears between whole numbers and fractions. An example of a decimal number is 25.5.

We must separate the whole number and fraction components of 2.655 in order to change it into a mixed number. The integer portion of the decimal, which is 2 in this instance, represents the full number.

We take the total number and divide it by the decimal to determine the fractional portion.

2.655 - 2 = 0.655

The combined number is therefore 2 and 655/1000.

By dividing the numerator and denominator by their largest common factor, we may reduce the fraction to its simplest form and so make it easier to understand. The highest common factor between 655 and 1000 in this instance is 5.

655 ÷ 5 = 131

1000 ÷ 5 = 200

Hence, 2 131/200 is the mixed number in its most basic form.

To find the equation of the drone's path, we can first find the coordinates of the center of the circle that the drone is flying around. We can do this by finding the midpoint between the two points the drone passes over:

Midpoint in the x-direction: (220 ft - 180 ft)/2 = 20 ft to the right of the origin.

Midpoint in the y-direction: (230 ft - 180 ft)/2 = 25 ft above the origin.

Therefore, the center of the circle is located at (20, 25) ft.

The radius of the circle can be found by calculating the distance between the center of the circle and either of the two points the drone passes over:

Radius: sqrt((20-(-180))^2 + (25-180)^2) = sqrt(40000 + 15625) = 205 ft (rounded to the nearest whole number)

So the equation for the drone's path is:

(x - 20)^2 + (y - 25)^2 = 205^2

To find how far north of Megan's position the drone is when it passes due north, we can substitute x = 0 into the equation:

(0 - 20)^2 + (y - 25)^2 = 205^2

400 + (y - 25)^2 = 42025

(y - 25)^2 = 41625

y - 25 = +/-sqrt(41625)

y = 25 +/- 204.06

So the drone is either 229.06 ft north or 22.94 ft south of Megan's position when it passes due north. Rounded to three decimal places, the answer is 229.06 ft north.

Answer:

g(f(-3)) = 6.

Step-by-step explanation:

To obtain the value of f(-3), we must first determine g(f(-3)), which requires changing x in the expression for f(x) to -3:

f(x) = 2x^2 + 9x - 1

f(-3) = 2(-3)^2 + 9(-3) (-3) - 1\s= 2(9) (9) - 27 - 1\s= 18 - 27 - 1\s= -10

Knowing that f(-3) = -10 allows us to replace it in the expression for g(x):

g(x) = -x - 4

g(f(-3)) = g(-10) (-10)

Now, if we replace x in g(x) with -10, we obtain:

g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6

Hence, g(f(-3)) = 6.

Answer:

g(f(-3))=6

Step-by-step explanation:

To calculate g(f(-3)), we must first determine the value of f(-3), and then we must insert that value into g(x) to obtain the result.

By adding x = -3 to the formula for f(x), we may obtain f(-3).

f(-3) = 2(-3)

² + 9(-3) - 1

f(-3) = 2(9) - 27 - 1

f(-3) = 18 - 28

f(-3) = -10

Knowing that f(-3) = -10 allows us to replace it in the formula for g(x):

g(f(-3)) = g(-10) = -(-10) (-10) - 4 = 10 - 4 = 6

Hence, g(f(-3)) = 6.

The correct option is (a) ŷ = -1.34x+21.5 , that is the best model to fit the scatter plot.

A scatter plot (or scatter chart, scatter graph) uses dots to represent values for two(2) different numeric variables. The position of each dot on horizontal and vertical axis indicates values for an individual data point.

The model of the equation best for the plot is,

ŷ = -1.34x+21.5

At point (1,20),

If the temperature is read every 12 hours, then the eighth temperature reading will be taken at 11.15 pm three days after the first reading.

Temperature is a measure of the degree of hotness or coldness of a substance or object, typically measured using a thermometer in degrees Celsius or Fahrenheit.

If the temperature is read every 12 hours, then the time interval between two consecutive temperature readings is 12 hours.

To find the time of the eighth temperature reading, we need to add 12 hours for each of the previous seven temperature readings:

First reading: 11.15 am

Second reading: 11.15 am + 12 hours = 11.15 pm

Third reading: 11.15 pm + 12 hours = 11.15 am (next day)

Fourth reading: 11.15 am (next day) + 12 hours = 11.15 pm (next day)

Fifth reading: 11.15 pm (next day) + 12 hours = 11.15 am (two days after the first reading)

Sixth reading: 11.15 am (two days after the first reading) + 12 hours = 11.15 pm (two days after the first reading)

Seventh reading: 11.15 pm (two days after the first reading) + 12 hours = 11.15 am (three days after the first reading)

Answer:

±6

Step-by-step explanation:

To find the possible values of x for a point on the circle with equation x² + y² = 64, we can substitute the given y-coordinate of √28 into the equation and solve for x:

x² + (√28)² = 64

x² + 28 = 64

x² = 64 - 28

x² = 36

Taking the square root of both sides, we get:

x = ±6

Therefore, the possible values of x for a point on the circle with coordinates (x, √28) are x = 6 and x = -6.

Answer: a. To shift the graph of f(x) downward 5 units, we subtract 5 from the function: f(x) - 5. To shift it left 3 units, we replace x with x + 3: f(x + 3) - 5. To stretch it vertically by a factor of 4, we multiply the entire function by 4: 4[f(x + 3) - 5]. Finally, to reflect it about the x-axis, we take the negative of the function: -4[f(x + 3) - 5]. Therefore, the equation of the new function g(x) is:

g(x) = -4[1/2^(x+3) - 5]

b. To find the y-intercept, we set x = 0 in the equation of g(x):

g(0) = -4[1/2^(0+3) - 5] = -4[1/8 - 5] = -4[-39/8] = 195/2

Therefore, the y-intercept is (0, 195/2).

c. The domain of g(x) is all real numbers, since there are no restrictions on x.

d. To find the range of g(x), we first observe that the function is decreasing and asymptotic to y = -5 as x approaches infinity. This means that the range of g(x) is all real numbers less than or equal to -5.

Work Shown:

Let's determine the derivative dy/dx.

Part 1

[tex]26x^{10} + 6x^{26}y+y^7 = 33\\\\ \frac{d}{dx}(26x^{10} + 6x^{26}y+y^7) = \frac{d}{dx}(33)\\\\ \frac{d}{dx}(26x^{10}) + \frac{d}{dx}(6x^{26}y)+\frac{d}{dx}(y^7) = 0\\\\ 10*26x^{10-1} + \frac{d}{dx}(6x^{26})y+(6x^{26})*\frac{dy}{dx}+7y^6\frac{dy}{dx} = 0\\\\[/tex]

There are many other possible ways to express the dy/dx expression.

GeoGebra and WolframAlpha are two useful tools to help verify the answer. Make sure you use the CAS mode in GeoGebra.

Part 3

Now that we know dy/dx, we can determine the slope of the tangent at any point (x,y) on the implicit function curve.

Plug in x = 1 and y = 1.

[tex]\frac{dy}{dx} = \frac{-260x^{9} - 156x^{25}y}{6x^{26}+7y^6}\\\\ \frac{dy}{dx} = \frac{-260(1)^{9} - 156(1)^{25}(1)}{6(1)^{26}+7(1)^6}\\\\ \frac{dy}{dx} = \frac{-260(1) - 156(1)(1)}{6(1)+7(1)}\\\\ \frac{dy}{dx} = \frac{-260 - 156}{6+7}\\\\ \frac{dy}{dx} = \frac{-416}{13}\\\\ \frac{dy}{dx} = -32\\\\[/tex]

The slope of the tangent line at (1,1) is m = -32.

Answer:

the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30 = 8 and 39/40.

Step-by-step explanation:

To find the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5, we need to first add the two summands:

4 and 2/3 + 5 and 2/5

To add these mixed numbers, we first need to find a common denominator. The least common multiple of 3 and 5 is 15.

4 and 2/3 can be written as an improper fraction with denominator 3:

4 and 2/3 = 4 x 3/3 + 2/3 = 12/3 + 2/3 = 14/3

5 and 2/5 can be written as an improper fraction with denominator 5:

5 and 2/5 = 5 x 5/5 + 2/5 = 25/5 + 2/5 = 27/5

Now we can add the two fractions with a common denominator of 15:

14/3 + 27/5 = (14 x 5)/(3 x 5) + (27 x 3)/(5 x 3) = 70/15 + 81/15 = 151/15

So, the sum of 4 and 2/3 and 5 and 2/5 is 151/15.

Now we can subtract 1 and 1/2 from this sum:

151/15 - 1 1/2

To subtract mixed numbers, we first need to convert 1 and 1/2 to an improper fraction:

1 and 1/2 = 1 x 2/2 + 1/2 = 2/2 + 1/2 = 3/2

Now we can subtract the fractions with a common denominator of 15:

151/15 - 3/2 = (151 x 2)/(15 x 2) - (3 x 15)/(2 x 15) = 302/30 - 45/30 = 257/30

Therefore, the result of subtracting 1 and 1/2 from the sum of 4 and 2/3 and 5 and 2/5 is 257/30.

The magnitude of the equilibrant force is 938.893 lb

We can use the concept of vector addition to solve this problem. The equilibrant force is the force that is needed to balance out the two given forces, so that the net force on the broken-down ship is zero.

Let's represent the two given forces as vectors A and B, with magnitudes of 750 lb and 630 lb, respectively. The angle between them is 34.5 degrees.

|C|^2 = |A|^2 + |B|^2 - 2|A||B|cosθ

where

θ is the angle between the two forces.

Substituting the given values, we get:

|C|^2 = (750 lb)^2 + (630 lb)^2 - 2(750 lb)(630 lb)cos(34.5°)

Simplifying this expression, we get:

|C|^2 = 562500 + 396900 - 945000 * cos(34.5°)

|C|^2 = 881520.0752

i) the inequality to show the number of ballons that the dance committee can buy is: 0.80b + 65 ≤ 125

ii)  solving the inequality above, we arrive at b ≤ 75
B) The graph is attached accordingly.

C) See the description of the solution below.

Let's start by defining our variables. Let b be the number of balloons that the dance committee could buy.

The cost of b balloons is $0.80b. We want to make sure that the cost of the balloons plus the amount already spent on decorations ($65) is less than or equal to the budget of $125. So we can write the following inequality:

0.80b + 65 ≤ 125

Now we can solve for b:

0.80b + 65 ≤ 125

0.80b ≤ 125 - 65

0.80b ≤ 60

b ≤ 75

Therefore, the dance committee can buy up to 75 balloons to stay within their budget.

To graph the solution set, we can plot b on the horizontal axis and shade the region to the left of b = 75, since b must be less than or equal to 75.

The solution set represents all possible values of b that satisfy the inequality. In this case, the solution set is b ≤ 75, which means that the dance committee can buy up to 75 balloons and still stay within their budget.

As the number of balloons increases, the cost of the balloons also increases, and the amount of money left in the budget decreases.

Therefore, the more balloons the dance committee buys, the less money they will have left for other decorations or expenses.
