Answer:
-12
Step-by-step explanation:
x = 12-3a
When a=8:
x = 12-3(8)
x = 12 - 24
x = -12
Answer:
1.
2.
3. The first one represents Dale's commission
Explanation:
1. The composition of the function
means that you first apply the function g(x) and then f(x) on the output of g(x).
That is:
- f(x) = 0.05x
- g(x) = x - 3000
2. The composition of the function
means that you first apply the function f(x) and then g(x) on the output of f(x).
That is:
3. Which one represents Dale's commission
To calculate Dales's commision you must subtract $3,000 from the sales, to find the sales over $3000. That is: x - 3,000, which is the function g(x).
Therefore, you first use g(x).
Then, you must multiply the output of g(x) by 0.05 to find the 5% of the sales over $3,000. That is: 0.05(g((x)) = 0.05(x - 3000) = 0.05x - 150.
Therefore, the composition that represents Dale's commission is the first one:
Answer:
C)
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The kite is split into 4 triangles. Calculate the area of each triangle and add them together to find the area of the kite.
The top two triangles have the same measurements of height 6 inches and base 8.5 inches. Use the formula 1/2 b*h and double the area to find for both triangles.
A = 1/2 (8.5)(6)(2) = 51 square inches
The bottom two triangles have the same measurements as each other as well. There height is 13 and base is 8.5. Repeat the same processes.
A = 1/2 (8.5)(13)(2) = 110.5 square inches.
Now add together 51 + 110.5 = 161.6 square inches.
