The spherical container has a radius of 4ft (where ft represents feet)
Its filled with gas that costs $12 per ft³
The value of gas in the container = ?
The volume of a sphere = 4/3
r³
The volume of the container = 4/3 ×
× 4³ ft³
One cubic foot = $12
4/3 ×
× 64 = How much?
Cross multiplying gives:
4/3 ×
×64 × $12 = $3216.99 (Rounded up to nearest one cent)
Rx + h = sx - k
rx - sx = -k -h
x ( r -s ) = -k -h
x = -k -h / r -s Ans
Answer:
it is 1/2
Step-by-step explanation:
Find slope as negative reciprocal of 2 => m=-1/2
y=mx + b
8=5(-1/2) +b
b=21/2
y= -1/2x +21/2
