2. A golf ball is hit with an initial vertical velocity of 64 ft/sec. The function h(t) = -16t2 +64t models the height h (in feet) of the golf ball at time t
(in seconds)
At what time, does the golf ball reach a height of 60 feet? You may use any method to solve.

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33

M. xyz =radians. covert this radian measure to its equivalent measure in degrees.

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels. ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0
