Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?

8 0

Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)

What time is 5 3/4 hours after 11:32 PM

Viktor [21]

Answer:

So the time is 5:17 a.m.

Explanation:

Note that:

11:32 pm is 28 minutes before midnight.

Adding the 534 hours will take the time into early morning.

So all we need to do to find the new time (am) is to subtract 28 minutes from 534 hours.

534→5 hours and 45 minutes

Subtracting the minutes:

45

28−− ← Subtract

17

So the time is 5:17 a.m.

Graph the inverse of the function.

Ghella [55]

Answer:

The graph of the inverse function is the same that the graph of the original function

Step-by-step explanation:

step 1

Find the equation of the function in the graph

Let

f(x) ---> the function in the graph

we know that

Is a linear function

take the points (0,6) and (6,0)

<em>Find the slope of the linear function</em>

$m=(0-6)/(6-0)\\m=-1$

<em>Find the the equation of the linear function in slope intercept form</em>

$f(x)=mx+b$

we have

$m=-1$

$b=6$ ---> the y-intercept is given

substitute

$f(x)=-x+6$

step 2

Find the inverse of the function f(x)

Let

y=f(x)

$y=-x+6$

<em>Exchange the variables (x for y and y for x)</em>

$x=-y+6$

Isolate the variable y

$y=-x+6$

Let

$f^{-1}(x)=y$

$f^{-1}(x)=-x+6$

$f^{-1}(x)=f(x)$

In this problem the graph of the inverse function is the same that the graph of the original function
