Ireally need with these problems ((−3/4)to the 5th power)to the third power. (−2.9)⋅(−2.9)to the 7th power, and (−3/4p)to the third power. sorry, the exponents weren't working. so much for me. i really need

Crickets can jump with a vertical velocity of up to 14 ft/s. which equation models the height of such a jump, in feet, after t seconds? h(t) = –16t2 + v0t + h0 h(t) = –16t2 + v0t + 14 h(t) = –16t2 + 14t h(t) = –16t2 + 14t + 14 what is the maximum height the cricket reaches? round to the nearest thousandth. h = feet
