Answer:

The linear function that models the population of bloater fish is y2 =  

✔ –92.57x + 1,052

.

The linear equation that determines when the two populations were equal is  

✔ –19.76x + 227 = –92.57x + 1052

.

The solution is x =  

✔ 11.33

What is x, if the volume of the cylinder is 768pi rcm3?
AVprozaik [17]

let's recall Cavalieri's Principle, <u>solids with equal altitudes and cross-sectional areas at each height have the same volume</u>, so even though this cylinder is slanted with a height = x and a radius = 8, the cross-sectional areas from the bottom to top are the same thickness and thus the same area, so its volume will be the same as a cylinder with the same height and radius that is not slanted.

\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=8\\ h=x\\ V=768\pi \end{cases}\implies 768\pi =\pi (8)^2(x)\implies 768\pi =64\pi x \\\\\\ \cfrac{768\pi }{64\pi }=x\implies 12=x
