n = [z*s/E]^2
n = [2.5758*14.1/1]^2 = 1320 (rounded up)
Answer:
2,143.57
Step-by-step explanation:
The equation for volume of a sphere is 4/3 x pie x r^3. Plug in 8 for r = 512. 512 x 3.14= 1,607.68. 4/3 x 1,607.68 is about 2,143.57
Answer:
$7.25
Step-by-step explanation:
Define the distance through the equation

The distance against the time is given by


When t=2s,


There is a error in 12.8feet.
b) When t=5sec



There is a error in 32 feet.
A = 1/2(b X h)
20.025 = 1/2(8.9 X u)
20.025*2/1= 1/2 * 2/1(8.9 x u)
40.05 =8.9u
40.05/8.9 = 8.9u/8.9
u = 4.50
Check
A = 1/2(b X h)
A = 1/2(8.9 X 4.5)
A = 1/2(40.05)
A = 20.025 in²
