Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x−7) ?
vitfil [10]
Assume that f(5)=8. So, (5, 8) is a point in the graph of f.

For g(x) to give us 8, we need x to be 12, because in that case we would have:

      g(12)=f(12-7)=f(5), which is 8. Thus, (12, 8) is a point on the graph of g.


Comparing (5, 8) in f, and (12, 8) in g, we can see that the graph of g is the graph of f shifted 7 units to the right.


Answer: <span>C) The graph of g(x) is the graph of ​f(x)​ translated 7 units right.</span>

A car is traveling at a speed of miles per hour. What is the car's speed in kilometers per hour? How many kilometers will the ca
mihalych1998 [28]

Complete Question:

As you may have intentionally forgotten to mention the important data elements in your question like at what rate a car is travelling and number of hours car will travel in required number of miles etc. After a little research it seems I have found the complete question you were supposed to write. Hence, I am answering based on this complete question, but anyways, it would certainly improve your concept. Here is the complete question:

<em>A car is traveling at a rate of 60 kilometers per hour. What is the car's rate in miles per hour? How many miles will the car travel in 4 hours? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not round your answers.</em>

<em>Answer:</em>

The car will travel 37.5 miles in one hour.

The car travel 150 miles in 4 hours.

<em>Fetching data from Question:</em>

The rate at which car is traveling: 60 kilometers per hour

one mile = 1.6 km

<em>a) How many miles a car will travel in one hour?</em>

<em>b) How many miles will the car travel in 4 hours?</em>

<em>Calculation:</em>

<em>a) How many miles a car will travel in one hour?</em>

As one mile is equal to 1.6 km.

The rate at which car is traveling: 60 kilometers per hour

So, just divide 60 with 1.6 to get in miles

                      i.e. 60/1.6 = 37.5 miles per hour  

So, the car will travel 37.5 miles in one hour.

<em>b) How many miles will the car travel in 4 hours?</em>

As the car will travel 4 hours.

And car travels 37.5 miles in one hour

So, just multiply the number of hours i.e. 4 with the miles in one hour (speed) i.e. 37.5 to calculate the distance in 4 hours. So,

                                 The distance =  speed × time

                                                        =  37.5  × 4

                                                        =  150 miles

So, the car travel 150 miles in 4 hours.

What is the area of the shaded region and the circle inside?

r=20,1m+13,2m=33,3m
A_1=\pi r^2
A_1=33,3^2\pi
A_1=1108,89\pi

What is the area of the circle inside?

A_2=20,1^2\pi
A_2=404,01\pi

What is the area of the shaded region?

1108,89\pi -404,01\pi =704,88\pi
704,88\pi \approx 704,88*3,14\approx 2213,3232\approx \underline{2213,32}

The answer: 2213,32 :)
