Answer:
height = 20.5068 m
Step-by-step explanation:
Given the data in the question;
First, lets calculate the amplitude, midline and period of 8minutes
Amplitude = 35 / 2 = 17.5
|A| = 17.5
A = - 17.5 { since the wheel starts at 6 o clock }
midline C = (35/2) + 3
C = 17.5 + 3
C = 20.5
And period is 8 minutes
⇒ 2π/B = 8
8B = 2π
B = 2π/8 = π/4
So our equation will be in the form of;
y = h(t) = Acos(B×t) + C
∴ h(t) = -17.5cos( π/4×t) + 20.5
Now, How high are you off the ground after 6 minutes
⇒ height = -17.5cos( π/4 × 6) + 20.5
height = -17.5cos( π/4 × 6) + 20.5
height = -17.5cos( 4.71238898) + 20.5
height = -17.5 × cos( 4.712) + 20.5
height = -17.5 × -0.00038898 + 20.5
height = 0.0068 + 20.5
height = 20.5068 m
Answer:
y = mnp/(m + n)
Step-by-step explanation:
I assume that both capital y and small case y are meant to be the same variable. If not, let me know, and I'll solve it again for small case y.
y/m + y/n = p
Factor y out on the left side.
y(1/m + 1/n) = p
y = p/(1/m + 1/n)
Multiply the right side by (mn)/(mn).
y = pmn/[(1/m + 1/n)mn]
y = pmn/(n + m)
y = mnp/(m + n)
Well it would make sense that Jenny had 6 marshmallows and Julie did not put any in, Hope this helped a little
