\(x = c y\\ x = \dfrac d z\)
\(x=3, y=3 \Rightarrow c = 2\\ x = 3, z=4 \Rightarrow d = 12\)
\(y=3 \Rightarrow x = 6 \Rightarrow z=2\)
1. Suppose a water tank in the shape of a right circular cylinder is thirty feet high and eight feet in diameter.
NO! Alan is correct!
I don't see it! As far as I can see the negative terms run from 1 cubed to 999 cubed so this term is as I wrote it.
"sketch a washer and find the volume of the solid generated by revolving the region bounded by y=8x-(x^2) and y=0.5(x^2) around the x axis --> Im not sure how to do this one."
∏[ (n(n+2)) / (n+4)^2, n, 1, 13] = 3 / 161,840
The problem says the ratio of the amount they spent on tacos, 6T, to the amount they spent on burritos, 2B, is 7:4.
You have the ratio of the price of tacos, to the price of burritos as 7:4.
I suppose it's a poorly worded problem.
Hello Alan: The second part evaluates to this: ∑[ (k^3), k, 1, 999] = 249,500,250,000, which is not correct. It should be written as follows: ∑[ (k - 1)^3, k, 999, 1] = 0, since the terms are continuously declining by 1.
The only possibilities are 0+-9 or 0-9. Both of em would be -9
-0 is not possible, bud
"sketch a washer and find the volume of the solid generated by revolving the region bounded by y=2x^2, y=0 and x=2 around the y-axis --> is 16pi the answer??"
(Yes, 16pi is the resulting volume).
