A car is at a distance s, in miles, from its starting point in t hours, given by s(t) = 10t2
a. Find s(2) and s(5).
b. Find s(5) – s(2). What does this represent?
c. Find the average rate of change from t = 2 to t=5. This is the average velocity.

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
