Cot y, if csc y =-10/3 and cos y< 0
fredd [130]
\csc y=-\dfrac{10}3\implies\sin y=-\dfrac3{10}

\cos^2y=1-\sin^2y\implies \cos y=\pm\sqrt{1-\dfrac9{100}}=\pm\dfrac{\sqrt{91}}{10}

You're told that \cos y, so omit the positive root.

\cot y=\dfrac{\cos y}{\sin y}=\dfrac{-\frac{\sqrt{91}}{10}}{-\frac3{10}}=\dfrac{\sqrt{91}}3

A train leaves Los Angeles at 2 p.m. heading north at 50 mph. If the next train leaves three hours later and also heads north at
Mamont248 [21]
Since the first train has been travelling for 3 hours, we have the following equations:
d=50t+3*50=50t+150
d=60t

We want to know when they will be equal, so set these equal to eachother:
60t=50t+150
10t=150
t=15

So 15 hours after the second train leaves, they will be at the same distance. This is at 8AM since the second train leaves at 5PM.
