P 27. Make Sense and Persevere A college's
business office found the relationship
between the number of admissions counselors
they employ and the college's profit from
tuition could be modeled by the function
y=-10x2 + 1,500x – 35,000.

a. Graph the function.
b. How many admissions counselors should the
college employ to maximize its profit?
c. What is the maximum amount of profit the
college can make?

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.

these are pretty self explanatory if you know what supp right and com angles are
