Aball is thrown from initial height of 2 feet with an initial upward velocity of 35 ft./s. the ball's height h (in feet) after t seconds is given by the following. h=2+35t-16t^2
find all values of t for which the ball's height is 20 feet. round your answer(s) to the nearest hundredth.

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
