Given the functions: f(x) = x^3,g(x) = x-7, h(x) = x + 2, which composition of functions would give you the new function n(x) = (x + 2)3 – 7?

A. n(x) = f(g(h(x)))
B. n(x) = g(f(h(x)))
C. n(x) = g(h(f(x)))
D. n(x) = h(f(g(x)))
E. n(x) = f(h(g(x)))

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.

answer: c i think
