Hello,
g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32
h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0
==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s
25=-16*1.25²+v*1.25
==>v=50/1.25=40
Equation h=-16t²+40*t
Answer:
r≈4.51yd
Step-by-step explanation:
The surface area of a sphere is given by the formula SA = 4r2, where r is the radius of the sphere. If the surface area of a sphere is 256 square yards, then the radius of the sphere is 4.51yd.
Formula: A=4πr^2
X=-2y+6
-2y+6+y=10
-y+6=10
-y=4
y=-4
X=14
2(14) + 2(-4)=28- -8=28+8=36
Answer is 36 I think
