Answer:
x = -1
Step-by-step explanation:
1/2 (3x +4 ) = 1/2
1/2 x 3x + 1/2 x 4 = 1/2
1.5 x + 2 = 1/2
1.5x = 1/2 -2
1.5x = -1.5
1.5x /1.5 = -1.5/1.5
x = -1
Check Back
1/2 ( 3 x -1 + 4) =1/2
1/2 ( 1) =1/2
1/2 =1/2
V(t) = 32t
when t = 3 seconds,
V = 32*3
V = 96
So velocity will be 96 units/s after 3 seconds.

Answer: 11 cans</h3>
======================================================
Explanation:
SA = surface area of the sphere
SA = 4*pi*r^2
SA = 4*pi*8^2
SA = 804.247719
The surface area is roughly 804.247719 sq ft.
I used the calculator's stored version of pi to get the most accuracy possible.
Since 1 paint can covers 75 sq ft, divide that surface area over 75 to find out how many cans you need.
804.247719/75 = 10.72330292
Round up to the nearest integer to get 11
You'll have leftover paint, but it's better to go over the goal than come up short.
