What is the recursive formula of the geometric sequence? 1∕2, 3∕4, 9∕8, 27∕16, ...
Question 16 options:

A)

an = (2) ⋅ (1∕2)n – 1 for n ≥ 1

B)

a1 = 1∕2; an = an – 1 ⋅ (3∕2) for n ≥ 2

C)

a1 = 1∕2; an = an – 1 ⋅ (2) for n ≥ 2

D)

an = (1∕2) ⋅ (1∕2)n – 1 for n ≥ 1

the answer is 15% decrease

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.

i believe the answer is 323 ft
