Answer:
$15.2
Step-by-step explanation:
2 because in the equation of a circle it is x^2 + y^2 = r^2, r=radius so you would take the square root of 4, leaving the radius of the circle to be 2.

Hope it helps you in your learning process.
The double angle formula for the sine is

The right hand side is exactly your expression, where 
So, rewriting the expression from right to left, we have

Answer:
<u>Domain:</u>
The domain of this can be any value between 0 to 565 miles per hour
<u>Range:</u>
The reasonable range can be the distance traveled which can be from 0 to 13,560 miles (no plane travel is longer than 24 hours, we assume).
Step-by-step explanation:
Domain is the input, set of x values for the function.
Range is the output, set of y values for the function.
This isn't a function essentially, but it is given that an Airplane travels at 565 miles per hour.
<em>We can say that the domain will be the speed of the airplane and the range would be the distance it travels.</em>

<u>Domain:</u>
The domain of this can be any value between 0 to 565 miles per hour
<u>Range:</u>
The reasonable range can be the distance traveled which can be from 0 to (565*24=13,560 miles) 13,560 miles (no plane travel is longer than 24 hours, we assume).
