Answer: y = -10 sin (πx) + 4
<u>Step-by-step explanation:</u>
y = A sin (Bx - C) + D
- Amplitude: A
- Period = 2π/B ---> B = 2π/Period
- Phase Shift = C/B --> C = B · Phase Shift
- D: midline, vertical shift
Given:
- A = 10
- B = 2π/2 = π
- C = B · 0 = 0
- D = 4
- reflection over x- axis
Equation:
y = -10 sin (πx - 0) + 4
Marcy
The school and Marcy are on the same x axis on the grid at -3 whilst Henry is the opposite end of the axis. Thus on the x axis Marcy is closer
On the y axis Henry is closer as they are both on 8 and Marcy is on 2
However overall Marcy is closer as the difference between -3 and 4 is 7 and the difference between 2 and 8 is 6
Hope this is right And hope it helps!
Answer:
11 pints
because 1 gallon is 8 pints
I think it’s 20d-$12
Hope this helps!
