Answer:
- Amplitude = 48
- Interpretation: The vertical distance from the center line to either the highest point or the lowest point is 48 feet. It represents half the total vertical distance from peak to valley.

Explanation:
The facts "The right lasts for 18 minutes" and "tickets are just $2" are not relevant to this question.
All we care about really is the h(t) function.
The general sine function is
y = A*sin(B(x-C)) + D
where
- |A| = amplitude
- B is used to find the period T = 2pi/B
- C is the horizontal phase shift
- D is the vertical shift and y = D is the center line
Here we have A = 48 so |A| = |48| = 48 is the amplitude. If you graphed the h(t) function, you would find that y = 55 is the center line and y = 55+48 = 103 is the highest y value possible, while y = 55-48 = 7 is the lowest y value possible.
In short, the Ferris wheel reaches the highest point of 103 feet and the lowest point of 7 feet off the ground.
Answer:
36
Step-by-step explanation:
The base is 16 inches.
The formula for the area of a triangle is
A = 1/2bh
We know that b = h+5, so we can rewrite this as:
A = 1/2(h+5)(h)
Using the area that we have, we now have:
88 = 1/2(h+5)(h)
We can cancel the 1/2 by multiplying by 2:
88*2 = (1/2)(h+5)(h)*2
176 = (h+5)(h)
Using the distributive property, we have:
176 = h² + 5h
We want quadratic equations to be set equal to 0, so we will subtract 176 from both sides:
176 - 176 = h² + 5h - 176
0 = h² + 5h - 176
Using the quadratic formula:

Since a negative length makes no sense, we know that h=11.
The base is 5 inches longer than the height, so b = 11+5 = 16.
