During a softball game, a batter hits a ball upward from an initial height of 3 feet. The height, in feet, of the softball is given by s(t)= -16t+70t+3, where t is the time in seconds and t=0 Which is the closest to the time when the softball will be 50 feet above the ground?

a. 0.66 sec
b. 5.03 sec
c. 0.83 sec or 3.55 sec
d. 0.66 sec or 5.03 sec

What is the solution to the following equation 2x^2-3x+2=0

the answers have i's and square roots in them??
