Answer:
Qinghai
Step-by-step explanation:
Part A
See the image labeled "part A". We'll use the values marked in blue and red for f(2) and g(2) respectively. These values are the function outputs when the input is x = 2.
(f-2g)(x) = f(x) - 2*g(x)
(f-2g)(2) = f(2) - 2*g(2)
(f-2g)(2) = 1 - 2*3
(f-2g)(2) = -5
Answer: -5
=====================================================
Part B
See the image labeled "part B". We'll use the values marked in blue and red for g(-1) and f(0) respectively.
We have to start with g(-1) and then chain it to finding f(0) afterward.
g(-1) = 0
f(g(-1)) = f(0) = 9
Answer: 9
=====================================================
Part C
See the image labeled "part C". We'll use the values marked in blue and red for g(-2) and g(-3) respectively.
Because g(-2) is the innermost function, it must go first, then g(-3) can go next.
g(-2) = -3
g(g(-2)) = g(-3) = 8
Answer: 8
ANSWER
The distance is 10 units.
EXPLANATION
Let us use the distance formula to find the distance between,

and

The distance formula is given by,

We plug in the values to get,





To find this answer, you must first find out how much each car makes them. You do 144 divided by 24 to do this. You get the answer 6. Which means that they make $6 for each car washed.
Now that you know how much each car wash makes them, you multiply 6 by 30 to get how much they earned on Sunday.
6 x 30= 180.
So, they earned B.$180 on Sunday
Assuming that angles X and Z are the same as A and C, the Y angle must be 75 degrees. It's because the sum of all three angles in any triangle give us 180 degrees, so:
180 - 45 - 60 = 75 degrees
