HEL A ball is shot into the air from the edge of a building, 50 feet above the ground. Its initial velocity is 20 feet per
second. The equation h(t) = -16t^2+20t + 50 can be used to model the height of the ball after t seconds.
About how long does it take for the ball to hit the ground? Round to the nearest tenth.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2
