1. What must the value of n be so that it satisfies 3.8x10" = 0.0038?
a.) n =- 3
b.)
n = 3
=
c.)
n =- 2
d.) n =- 4

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.

answer is  

a.

7 in. x 11 in.

hope you get this right.
