Answer:
Volume of solid is
Step-by-step explanation:
We need to find the volume of solid formed by rotating the region bounded by the graph of , y-axis and the line y=3 about the line y=5.
Please see the attachment for figure.
Using Shell method,
where,
a=0 (Lower limit of solid)
b=4 (Upper limit of solid)
(Outer Radius of Shell)
r=2 (Inner radius of shell)
dx is thickness of shell
Volume of shell, dV=Area of shell x Thickness
Volume of solid
Thus, Volume of solid is
Answer:
k = 2P /x^2
Step-by-step explanation:
P = 1/2 kx^2
Multiply each side by 2
2P = 2*1/2 k x^2
2P = k x^2
Divide each side by x^2
2P / x^2 = k x^2 / x^2
2P /x^2 =k
Jack's age is 14, so his age can't be 14 - g
Mara's age is 14 - g, which means she is g years young than Jack(not older because if she was older, you would need to add not subract)
The answer is B.
