Answer:
B
Step-by-step explanation:
5t < -15 (divide by 5 on each side)
t < -3
1. Square
2. (0, 0), (6,3) (6,13),(-0.5,0)
well, let's say we know "r" and also "y", can we get the angle and the rectangular "x"?
![\bf \begin{cases} y=rsin(\theta )\\ x=rcos(\theta ) \end{cases} \\\\[-0.35em] ~\dotfill\\\\ y=rsin(\theta )\implies \cfrac{y}{r}=sin(\theta )\implies sin^{-1}\left( \cfrac{y}{r} \right)=\theta](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Bcases%7D%20y%3Drsin%28%5Ctheta%20%29%5C%5C%20x%3Drcos%28%5Ctheta%20%29%20%5Cend%7Bcases%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20y%3Drsin%28%5Ctheta%20%29%5Cimplies%20%5Ccfrac%7By%7D%7Br%7D%3Dsin%28%5Ctheta%20%29%5Cimplies%20sin%5E%7B-1%7D%5Cleft%28%20%5Ccfrac%7By%7D%7Br%7D%20%5Cright%29%3D%5Ctheta)
and once we know what angle θ is, since x = rcos(θ), we know "r" already, and we know θ as well, so we know "x" as well.
