If f(x)=2x-1 and g(x)=3x, then (g º f)(-2)

   -15

Step-by-step explanation:

g(x)= 3x

(g*f)=3(2x-1)

(g*f)(x)=6x-3

(g*f)(-2)=6(-2)-3

           =-12-3

          =-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.
