A construction company has adjoined a rectangular enclosure of $1000-\mathrm{ft}^2$ to its office building. Three sides of the enclosure are fenced in. The side of the building adjacent to the enclosure is $100 \mathrm{ft}$ long and a portion of this side is used as the fourth side of the enclosure. Let $x$ and $y$ be the dimensions of the enclosure, where $x$ is measured parallel to the building, and let $L$ be the length of fencing required for those dimensions. What is the domain of the function in part (b) ?

As shown in the accompanying figure, a camera is mounted at a point $3000 \mathrm{ft}$ from the base of a rocket launching pad. The rocket rises vertically when launched, and the camera's elevation angle is continually adjusted to follow the bottom of the rocket.

Find the domain of the function in the previous part.
