Which of the following functions represents f(n), the number of small squares in figure n? A. f(n) = (n + 1)^2 - 1
B. f(n) = 2n^2 + 1
C. f(n) = n^2-1
D. f(n) = (n + 1)^2 + 1

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.

72 is the answer to this problem

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
