Find the length s of the arc of a circle of radius 20 miles subtended by the central angle 1/5 radian

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368

answer: 104.283185

step-by-step explanation:

3.14159265359 + 3.14159265359= 6.28318530718

since you're subtracting 3 twice, i'm just gonna say -6

6.28318530718 - 6 = 0.28318530718

0.28318530718 + 5 = 5.28318530718

5.28318530718 + 99 = 104.283185307

no idea how or if it wants you to round, but there are 2.18 students per teacher(if you meant 3 and not 33 it would be 24 students per teach), 11 students per tutor, and you would need 12 tutors for 132 students.
