Noah's cousin is exactly 7 years younger than Noah. Let M represent Noah's cousin's age in months and N represent Noah's age in years. 1. If Noah is 15 years old, how old is his cousin, in months? 2. When Noah's cousin is 132 months old, how old is Noah, in years? 3. Write a function that gives the age of Noah's cousin in months, as a function of Noah's age in years. 4. Write the inverse of the function you wrote. What are the input and the output of this inverse function?​

Answers

Answer 1

Answer:

1,if Noah is 15 his cousin is 8 or 96 months

2, and when Noah's cousin is 132 months or 11 years old Noah will be 18

3,n-[[7]12]=age of Noah's cousin

Step-by-step explanation:

1,15-7=8

1 part 2, 8*12=96

2,132/12=11

2 part 2,

11+7=18

3,n-[[7]12]=age of Noah's cousin

4,n+[7/12]

if n=18

18+[7/12]

or

18+0.5833=18.5833

Find the surface area of a sphere with a radius of 2√2 feet.
94.5 square feet
100.5 square feet
25.1 square feet
35.5 square feet

Answers

Answer: 100.5 square feet

Step-by-step explanation:

To find : surface area of sphere with radius of [tex]2\sqrt{2}feet[/tex]

The formula used to calculate surface area of sphere is = [tex]4\times \pi\times r^2[/tex]

where r is the radius of sphere.

Putting the values we get:

surface area of sphere = [tex]4\times 3.14\times (2\sqrt{2}feet)^2=100.5square feet[/tex]

Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet

Answer:

100.5 square ft

A group of friends were working on a student film. They spent all their budget on props and equipment. They spent $693 on props, and 37% of the total budget on equipment. What was the total budget for their student film?

Answers

Answer:

$1100

Step-by-step explanation:

Let the total budget = b

amount spent on props + amount spent on equipment = total budget

If 37% of the budget was spent on equipment

The percentage spent on props = 100% - 37% = 63%

63% of the total budget is $693

the above sentence presented as an equation gives :

63/100 x b = 693

to find b, divide both sides of the equation by 100/63

b = $1100

Answer:

1100

What is the equation of a line passing through two points?

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

From the equation, the two points of Dave's line will be (0, 6) and (2, 9). Then the equation is given as,

(y - 6)[(9 - 6) / (2 - 0)](x - 0)

y = 1.5x + 6

From the equation, the two points of Andrew's line will be (0, 3) and (1, 5). Then the equation is given as,

(y - 3) = [(5 - 3) / (1 - 0)](x - 0)

y = 2x + 3

The number of hours when the amount Andrew and dave pay for the rentals be equal will be calculated as,

2x + 3 = 1.5x + 6

0.5x = 3

x = 6 hours

The number of hours when the sum Andrew and dave pay for the rentals be equivalent will be 6 hours.

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1
