Need asap. will give brainliest of course.

the graph shows the distance, y, that a car traveled in x hours:

what is the rate of change for the relationship represented in the graph?

1/50
1/25
25
50

The rate of change is 25 miles per hour

Step-by-step explanation:

The rate of change is given by

f(x2) - f(x1)

x2-x1

Let x2 =4 and x1 =0

f(4) = 100 and f(0) = 0

100-0

4-0

100

4

25

The rate of change is 25 miles per hour

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer

the cost of the apple depends on the weight

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
