$\frac{4}{5} - \frac{3}{10} \\ 
 \\ \frac{4*2}{5*2}= \frac{8}{10} \\ 
 \\ \frac{3*1}{10*1}= \frac{3}{10} \\ 
 \\ \frac{8}{10} - \frac{3}{10}= \frac{5}{10} \\ 
 \\ \frac{5:5}{10:5}= \frac{1}{2} \\ 
 \\ Solution: \frac{1}{2} \\$

Answer:

Step-by-step explanation:

Find the average rate of change of each given function over the interval [-2, 2]]:

✔️ Average rate of change of m(x) over [-2, 2]:

Average rate of change = $\frac{m(b) - m(a)}{b - a}$

Where,

a = -2, m(a) = -12

b = 2, m(b) = 4

Plug in the values into the equation

Average rate of change = $\frac{4 - (-12)}{2 - (-2)}$

= $\frac{16}{4}$

Average rate of change = 4

✔️ Average rate of change of n(x) over [-2, 2]:

Average rate of change = $\frac{n(b) - n(a)}{b - a}$

Where,

a = -2, n(a) = -6

b = 2, n(b) = 6

Plug in the values into the equation

Average rate of change = $\frac{6 - (-6)}{2 - (-2)}$

= $\frac{12}{4}$

Average rate of change = 3

✔️ Average rate of change of q(x) over [-2, 2]:

Average rate of change = $\frac{q(b) - q(a)}{b - a}$

Where,

a = -2, q(a) = -4

b = 2, q(b) = -12

Plug in the values into the equation

Average rate of change = $\frac{-12 - (-4)}{2 - (-2)}$

= $\frac{-8}{4}$

Average rate of change = -2

✔️ Average rate of change of p(x) over [-2, 2]:

Average rate of change = $\frac{p(b) - p(a)}{b - a}$

Where,

a = -2, p(a) = 12

b = 2, p(b) = -4

Plug in the values into the equation

Average rate of change = $\frac{-4 - 12}{2 - (-2)}$

= $\frac{-16}{4}$

Average rate of change = -4

The answer is D. Only p(x) has an average rate of change of -4 over [-2, 2]

258.5 miles in 5.5 hours. also please show your work on paper or on here in a understandable way

Y_Kistochka [10]

Answer:

47 miles per hour

Step-by-step explanation:

so you have to do distance/time and divide the numbers.

so put 258.5 at the top because it's the distance then you put the time under it so 5.5 hour and divide that and you get 47 mph
