Anna walked 8 miles in 3 hours. Juan walked 14 miles in 5 hours. Are these rates in proportion?

Veronika [31]

These rates are not in proportion. Juan walked faster.

Explanation:

First, we want to make these ratios to have the same denominator so we can compare the numerators. To do this, do 3x5 and 8x5 to get 40:15. Then, we do 5x3 and 14x3 to get 42:15. Now we can just compare the numbers 40 and 42, and since 42 < 40, we know Juan walked faster.

Given f(x) =17 -x2 what is the average rate of change in f(x) over the interval [1,5]

Artist 52 [7]

By definition the average rate of change is given by:
 $AVR = \frac{f(x2) - f(x1)}{x2-x1}$
We have the following function:
 $f(x) =17 - x^2$
We evaluate the function for the given interval:
For X = 1:
$f(1) =17 - 1^2$
$f(1) =17 - 1$
$f(1) =16$
For X = 5:
$f(5) =17 - 5^2$
$f(5) =17 - 25$
$f(5) =-8$
Then, replacing values we have:
$AVR = \frac{-8 - 16}{5-1}$
$AVR = \frac{-24}{4}$
$AVR = -6$
Answer:
the average rate of change in f(x) over the interval [1,5] is:
 $AVR = -6$

The range of the following relation R {(3, -5), (1, 2), (-1, -4), (-1, 2)} is (1 point)

kolbaska11 [484]

Answer:

{-5,-4,2}

Step-by-step explanation:

The domain is the inputs and the range is the outputs

The outputs are the y values

{ -5,2,-4,2}

We only list them once and in order from smallest to largest

{-5,-4,2}
