Answer:
It will take them roughly 7.27 mintues
Step-by-step explanation:
To find this, model the amount of apples that can collect a minute using m as the minutes.
Isaac = 3m
Juanita = 5m/2
Now we can add them together and solve for when they will have 40 apples.
3m + 5m/2 = 40
5.5m = 40
m = 7.27
Answer:
=x^2 -14xy+49y^2
Step-by-step explanation:
(x − 7y)^2
= (x-7y)(x-7y)
= x^2 -7xy-7xy+49y^2
=x^2 -14xy+49y^2
Step-by-step explanation:
General form of a sine or cosine wave is:
y = ±A sin((2π/T) t) + B
y = ±A cos((2π/T) t) + B
where A is the amplitude, T is the period, and B is the vertical offset or midline.
The Ferris wheel is 80 meters in diameter or 40 meters in radius.
A = 40
The Ferris wheel turns once every 8 minutes.
T = 8
The lowest point is 5 meters above the ground, so the center of the Ferris wheel is 45 meters above the ground.
B = 45
At t=0, you're at the lowest point, so use -cos.
Therefore, the equation is:
y = -40 cos(2π/8 t) + 45
y = -40 cos(π/4 t) + 45
When t = 5:
y = -40 cos(5π/4) + 45
y = 20√2 + 45
y ≈ 73.3 meters
When y = 35:
35 = -40 cos(π/4 t) + 45
-10 = -40 cos(π/4 t)
1/4 = cos(π/4 t)
π/4 t ≈ 1.318
t ≈ 1.68 minutes
