8 for a cd and start with $15

Step-by-step explanation: Here, notice that the value that we

don't know is how many CDs are purchased.

Since CD's cost $8, we multiply 8 by our variable, which is x.

So we have 8 times x or 8x.

In addition, since there is a one time fee

of $15 to begin, we add 15 to 8x.

So we have 8x + 15.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
