The graph represents the cleaning costs charged by a housekeeping service.
which statement is true of the cost function?

a.) a cleaning time of 2 hours will cost $100.
b.) a cleaning time of 6 hours will cost $150.
c.) cost is a fixed rate of $100 for jobs requiring more than 2 hours, up to a maximum of 6 hours.
d.) cost is a fixed rate of $200 for jobs that require at least 6 hours.

C- Cost is a fixed rate of $100 for jobs requiring more than 2 hours, up to a maximum of 6 hours

Step-by-step explanation:

 The correct option is

(C) Cost is a fixed rate of $100 for jobs requiring more than 2 hours, up to a maximum of 6 hours.

Step-by-step explanation:  We are given a graph that represents cleaning costs charged by a housekeeping service.

We are to select the statement that is TRUE of the cost function.

Option (A) is

"A cleaning time of 2 hours will cost $100."

Since there is an open circle at the point (2, 100) and a closed circle at (2, 50), so a cleansing time of 2 hours will cost $50.

Thus, option (A) is NOT CORRECT.

Option (B) is

"A cleaning time of 6 hours will cost $150."

Since there is a closed circle at the point (6, 100) and an open circle at (6, 200), so a cleansing time of 6 hours will cost $100.

Thus, option (B) is NOT CORRECT.

Option (C) is

"Cost is a fixed rate of $100 for jobs requiring more than 2 hours, up to a maximum of 6 hours."

Since there is an open circle at the point (2, 100) and a closed circle at (6, 100), so a cleansing time of more than 2 hours up to a maximum of 6 hours will cost a fixed rate of $100.

Thus, option (C) is CORRECT.

Option (D) is

" Cost is a fixed rate of $200 for jobs that require at least 6 hours."

Since there is an open circle at the point (0, 50), closed circle at (2, 50), open circle at (2, 100) and a closed circle at (6, 100).

So, the price lies between $50 and $100 for jobs that require at least 6 hours.

Therefore, the price is not fixed.

Thus, option (D) is NOT CORRECT.

Option (C) is the correct option.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
