Answer:

The average speed of the car is 0.75 miles per minute.

Step-by-step explanation:

Ava starts checking her car’s clock at mile marker 0. It takes her 4 minutes to reach mile marker 3.

When she reaches mile marker 6, she notes that 8 minutes total have passed since mile marker 0.

We will find the slope of the function in the given interval to get the average speed.

V=\frac{y2-y1}{x2-x1}

Putting the values we get;

V=\frac{6-3}{8-4} =\frac{3}{4}

or V = 0.75

Therefore, the average speed of the car is 0.75 miles per minute.

A building with a height of 32 m casts a shadow that is 20 m long. A person standing next to the building casts a shadow that is
r-ruslan [8.4K]

Answer:

Building's actual height 32 meters

Building's shadow height 20 meters

Person's shadow height 1.2 meters

Person's actual height = ?

Find the person's actual height:

This is a proportion problem.

Actual height to shadow height

Building = Person

32 : 20 = x : 1.2

32 * 1.2 = 20 * x

38.4 = 20x

38.4/20 = 20x/20

1.92 = x

The person's actual height is 1.92 meters long.

32 : 20 = 1.92 : 1.2

32/20 = 1.60

1.92/1.2 = 1.60

Answer:

Part 1) The inverse function is f^{-1}(x) =\frac{2x-3}{4}

Part 2) 25.75 weeks

Step-by-step explanation:

Let

x ---->the number of weeks in the  course

f(x) ---> the number of assignments he has completed

we have

f(x)=\frac{4x-3}{2}

Part 1) Find the inverse

Let

y=f(x)

y=\frac{4x-3}{2}

Exchange the variables (x for y and y for x)

x=\frac{4y-3}{2}

Isolate the variable y

2x=4y-3\\4y=2x+3\\\\y=\frac{2x+3}{4}

Let

f^{-1}(x) =y

so

f^{-1}(x) =\frac{2x+3}{4}

Part 2) we have

f^{-1}(x) =\frac{2x+3}{4}

where

f^{-1}(x) ---->the number of weeks in the  course

x ---> the number of assignments he has completed

For x=50

substitute in the inverse function

f^{-1}(x) =\frac{2(50)+3}{4}=25.75\ weeks

Note: Juliana don't need to use the inverse function. you can just use the function you have where f(x)=50 assignments and solve for x to get the amount of weeks.

so

50=\frac{4x-3}{2}\\\\100=4x-3\\4x=103\\x=25.75\ weeks
