9. If f(1)=8 and f(n)={f(n-1)+2 then which of the following is the value of f(3)? (1) 5
(3) 3
(2) 7
(4) 6

see below for explanation

Step-by-step explanation:

f(1)=8 so f(2)=8+2=10 and f(3)=12

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.

6 on both sides and twelve on the top and the bottom
