Exercises 1.4

For part (a), I must evaluate each interval [a, b] this way:

Let A(t) = average velocity

A(t) = [(10(b) - 1.86(b)^2] - [(10(a) - 1.86(a)^2] ÷ (b - a)

For part (b), I must find derivative of the given function and then evaluate when t = 1.

Yes

use

b. yes
The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t.

Yes, that is what you are to do. Why haven't you done it?
