Hello :
cscx = -5/2
1/sinx =-5/2
sinx=-2/5
sin²x+cos²x=1
4/25+cos²x=25/25
cos²x = 21/25
between 270 and 360 : cosx > 0 cosx=(<span>√21)/5
but : sin2x =2sinx cosx
sin2x = 2(-2/5)(</span>(√21)/5)
sin2x = (-4√21)/25

This is a problem of
System of Equations. So in this problem we have two rental car companies. Thus, we can write a system of equation by analyzing the statements step by step:
<span>
One rental car company charges $65 per day with unlimited miles:
That is the final cost you will pay, in dollars, at the end of the day, by using the car will be:
</span>

This is true because this company offers you a plan for unlimited miles.
<span>
Another rental car company charges $42 per day plus $0.20 per mile:
In a mathematical language that is:
</span>

<span>
Therefore, f</span><span>or a one-day rental, the mileage that makes the cost of the two options equal is</span><span>:
</span>
