Find cot θ if csc θ = negative square root of thirty seven divided by six and tan θ &gt; 0.
Ket [755]
You can use the trigonometric identity  1+\cot^2{x}=\csc^2{x}.

1+\cot^2{\theta}=(\frac{-\sqrt{37}}{6} )^2 \\ 1+\cot^2{\theta}=\frac{37}{36} \\ \cot^2{\theta}=\frac{1}{36} \\&#10;\cot{\theta}=\frac{1}{6}

The requirement that \tan{\theta}\ \textgreater \ 0 eliminates -1/6 from being another solution.

A cyclist rides her bike at a rate of 2 meters per second. What is this rate in kilometers per hour? How many kilometers will th
Oksanka [162]

The speed v is 12 m/s.

 

You need to convert the seconds to hours  and meters to kilometers:

 

3600s = 1 hr

 

If you divide 3600 on both sides you will get

 

1 s = (1/3600) hr

 

 

1000m = 1 km

 

If you divide 1000 on both sides you will also get

 

1 m = (1/1000) km

 

 

v = [(12/1000) km] / [(1/3600) hr]

 

v = [(12*3600)/1000] km/hr

 

v = 216/5  km/hr

 

 

The distance in 4 hours is

 

d = [(216/5) km/hr] * 4hr

 

d = 864.50 km

This is why your answer should be 12 m/s

Hope this helps!! - Queenb369

How do I find the area of a composite figure
azamat
It depends on what the composite figure is, but use the formulas, such as A=1/2bh for the triangle and A=bh, for the square and the rectangle.
