The small pizza is 8 inch what the circumference plz help

h = -16t² + 30t + 4

4; 15; 18; 13; 2

Step-by-step explanation:

Convention: upwards positive

s = ut + ½at²

s = h - 4 (because its already at a height of 4 feet)

u = 30

a = -32

h - 4 = 30t + (½)(-32)t²

h = -16t² + 30t + 4

h = -16t² + 30t + 4

Plug in t to find h:

t = 0, h = 4

t = 0.5, h = 15

t = 1, h = 18

t = 1.5, h = 13

t = 2, h = 0
