Answer:
y = 9 cos [(⅕pi)x]
Step-by-step explanation:
Amplitude = 9
Period = 10
2pi/10 = pi/5
For this case, the first thing we must do is define variables.
We have then:
x: number of cabins
y: number of campers
We now write the equation that models the problem:

We know that there are 148 campers.
Therefore, substituting y = 148 in the given equation we have:

From here, we clear the value of x:

Therefore, the number of full cabins is:

Answer:
The number of full cabins is:

7.5 - 3.2 = 4.3 + 4 = 8.3^3 = 571.787 ÷ 2 = 285.8935 rounded to 285.9
Answer:f=10 and g(x)=4x
Step-by-step explanation:
Answer: 5
Step-by-step explanation:
Because the shape is a kite we can tell that WX and WZ are congruent.
So 4x-8 = 2x+2
Add 8 to both sides
4x = 2x+10
Subtract 2x
2x = 10
Divide by 2
x = 5
