10 times the sum of 2 and 1 is represented by the following expression:

10 x (2 + 1)

10 x is ten times, and (2 + 1) the sum of 2 and 1, "10 times the sum of 2 and 1".

Find the volume of the ellipsoid x2+y2+4z2=100x2+y2+4z2=100.
kondor19780726 [428]
Given the ellipsoid x^2+y^2+4z^2=100

For the radius in the x-dirextion, y = z = 0, and we have

x^2=100 \\  \\ \Rightarrow x=\pm10

For the radius in the y-dirextion, x = z = 0, and we have

y^2=100 \\  \\ \Rightarrow y=\pm10

For the radius in the z-dirextion, x = y = 0, and we have

4z^2=100 \\  \\ \Rightarrow z^2=25 \\ \\ \Rightarrow z=\pm5

Thus, the radius of the ellipsoid is given by

Volume=4\pi r^3=4\pi\times10\times10\times5=500\pi

C = 125S + 6500.


This is because there is an initial fee of $6500 to rent the truck and an additional 125 dollars for each ton of sugar.


C = 125(13) + 6500

C = $8125
