A bird picks up a stone and drops it while flying the function y=64-16t^2 represents the height y in feet of the stone t seconds after it dropped. The stone hits the top of a 15 foot tall building. After how many seconds does the stone hit the building?

Solve the system of equations. y= 2x y= x^2 - 15

Consider the following equation -167 + 37 = 49 - 21p select the equation that has the same solution as the given equation. o a. p - 5 + ip = 7 - p ob. +55 + 12p = 5p + 16 c. 2 + 1.25p = -3.75p + 10 d. -14 + 6p = -9 - 6p reset next
