Answer:
12
Step-by-step explanation:
3(4 + 2) - 6
3 * 6 - 6
18 - 6
= 12
Hello!
Amplitude is the maximum displacement on the graph of a function.
Period is the displacement of x at which the graph of a function begins to repeat.
We can find the period of a circular function by using the formula:
.
The amplitude is 6 because it causes the displacement of the graph to change. Therefore, the domain becomes -6 ≥ x ≥ 6.
To find the period, we use the formula
, and we substitute the values into the equation. The value B, is 1/3.
![P = \frac{2\pi}{\frac{1}{3}}](https://tex.z-dn.net/?f=%20P%20%3D%20%5Cfrac%7B2%5Cpi%7D%7B%5Cfrac%7B1%7D%7B3%7D%7D%20)
This can be simplified into 6π.
Since the periodicity is 6π, the graph hits the x-axis at intervals of 3π and -3π, and the graph also hits the x-axis at the origin.
Therefore, the amplitude of the function is 6, the period is 6π, and the function hits the x-axis during intervals of 3π.
Log x+ log 7= log 42
log x=log 42 - log 7
log x=log 42/7 [ log a - log b= log (a/b) ]
log x= log 6
therefore:
x=6
Answer: x=6

What is the area the sprinkler can water?
Area = π r²
r = 18 feet
r² = r * r = 324
A = 3.14 * 324
A = 1017.36
A = 1017 square feet
