A watermelon is tossed off the top of a building. The function h(t) = -16t2 + 68t + 128 describes the watermelon's height, h, in feet, t seconds after it was thrown. What is the average velocity of the watermelon over the interval |1, 2.2|7 If necessary, round your answer to at least two decimal places. ft/s What is the instantaneous velocity of the watermelon at time t - 2.2 ? If necessary, round your answer to at least two decimal places. ft/s > Next QuestionSuppose f(5) - 4, f'(5) = 3. Approximate f( 4.98). f(4.98) ~ enter your answer rounded to two decimal places) If f"(5) - -9 is the approximation you found for f(4.98) an over-estimate or an under-estimate? Select an
