Answer:
B=80
Step-by-step explanation:
B is the same answer as the number on the other side
-2/5 +1/2w = -6/7
move the -2/5 over by addition
1/2w = -16/35
w = -32/35
Answer:
y=(2/3)(x+15)-22
Step-by-step explanation:
You use the slope point equation which is y-y1=m(x-x1) or y=m(x-x1)+y1 where m is the slope and x1 and y1 are the coordinates you plug in.
Therefore, 2/3 is the slope m and (-15, -22) are the coordinates for x1 and y1.
y=(2/3)(x-(-15)) + (-22)
y=(2/3)(x+15)-22
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.
