The total cost f(x), in dollars, for renting a bike for x hours is shown:
f(x) = 10 + 20x
what does f(10) represent?
a. the number of miles the bike can travel for a cost of $10  the b. number of miles the bike travels in 10 hours  the number of c. hours the bike can be rented for a cost of $10  the number of d. dollars it costs to rent the bike for 10 hours

D

Step-by-step explanation:

($20/hr) is the hourly rental rate, and x is the number of hours for which the bike is rented.

In    f(x) = 10 + 20x   letting x = 10 results in the total rental cost of the bike for 10 hours (Answer D)

d i took the test

Step-by-step explanation:

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.

y=1/4x-4
