A hot-air balloon rises vertically from the ground so that its height after t sec is given by the following function. h = 1 2 t2 + 1 2 t ft where (0 <= t <= 60) (a) What is the height of the balloon at the end of 33 sec? Incorrect: Your answer is incorrect. ft (b) What is the average velocity of the balloon between t = 0 and t = 33? Incorrect: Your answer is incorrect. ft/sec (c) What is the velocity of the balloon at the end of 33 sec? Incorrect: Your answer is incorrect. ft/sec

Step 1
h = 1/2(33)^2 + 1/2(33) h = 1/2(1089) + 1/2(33) h = 544.5 + 16.5 h = 561 ft Show more…

A hot-air balloon rises vertically from the ground so that its height after t s is given by the following function: h = 1/2 t^2 + 1/2 t ft where (0 ≤ t ≤ 60) (a) What is the height (in ft) of the balloon at the end of 39 sec? (b) What is the average velocity (in ft/sec) of the balloon between t = 0 and t = 39? (c) What is the velocity at time t? v(t) = What is the velocity (in ft/sec) at the end of 39 sec?
