We are to answer the questions given the sales and advertisement function
The answers are given below
Given:
S = 9000 + 12A
Where,
S = Monthly sales revenue
A = monthly advertising expenditure
a. If the firm does not spend on advertisement
S = 9000 + 12A
Where,
A = 0
S = 9000 + 12A
S = 9000 + 12(0)
S = $9000
b. If the firm spends $800 on advertising one month
S = 9000 + 12A
= 9000 + 12(800)
= 9000 + 9600
= 18,600
S = $18,600
c. S = 9000 + 12A
When
S = $15,000
15,000 = 9000 + 12A
15000 - 9000 = 12A
6000 = 12A
A = 6000/12
= 500
A = $500
d. If the firm increases monthly expenditure on advertising by $1
If A increases to $501
S = 9000 + 12A
= 9000 + 12(501)
= 9000 + 6,012
= 15,012
S increases to $15,012

Answer:
B 12 pi m^2
Step-by-step explanation:
The area of the circle is pi r^2
We know the radius is 6
A = pi (6)^2 = 36 pi
The sector is 120 degrees. The entire circle is 360 degrees.
The fraction is 120/360 = 1/3
The sector covers 1/3 of the circle so it is 1/3 of the area
1/3 A = 1/3 (36 pi) = 12 pi
The probability of drawing a white marble followed by a yellow marble, without replacing the white marble is 0.091
<h3>How to determine the probability?</h3>
The distribution of the marbles is given as:
White = 3
Yellow = 4
Green = 5
Total = 12
The probability of selecting a white marble is:
P(White) = 3/12
Now, there are 11 marbles left.
The probability of selecting a yellow marble is:
P(Yellow) = 4/11
The required probability is:
P = 3/12 * 4/11
Evaluate
P = 0.091
Hence, the probability of drawing a white marble followed by a yellow marble, without replacing the white marble is 0.091

I don't know which quadrent the rectangle started in because there is no image, but it should be easy for you to apply the steps. You know that it is being reflected over the x-axis, this means that x will stay the same, and y will be negative. The x axis is the horizontal one, so if you look at where it is, you can either visualize, or use tracing paper to determine where it will end up.
