Answer:
g(f(x)) = (x + 9)^2 or x^2 + 18x + 81
Step-by-step explanation:
(gºf)(x) is the "c .... " of two functions f(x) and g(x): f(x) is the input to g(x).
We start with g(x): g(x) = x^2. We replace the first x with f(x) and the second x with x + 9:
g(f(x)) = (x + 9)^2 or x^2 + 18x + 81
Answer:
g(4)=3
Step-by-step explanation:
We need slope/rate of the table
Slopes of all options
- 5/7=25/21
- 3/5=9/15
- 1/3
- 7/9
- 7/11=21/33
Option D is correct
Option
Answer:
Answer for 4th question
b = 7
Answer for 5th question
area= 99sq.in
Step-by-step explanation:
4. area of parallelogram= base × height
28= b × 4
b= 28/4
b = 7
5. area of parallelogram= base × height
area= 9 × 11
area= 9 sq.in
The formula is:
Total time = (hose1 * hose2) / (hose1 + hose2)
Total time = (5 * 4) / 5 + 4
Total time = 20 / 9
Total time = 2 + (2/9)
Total time = 2.22222...
