I believe the answer is B., weight when sold because it is dependent on x, the time(feed for one year).
There are 60 seconds in a minute. there are 40,000 in a second. That means we have to multiply that by 60.
60*40,000= 2,400,000
The answer is 2,400,000 gallons per minute.
Answer:
The value of 
which makes the equation true.
Step-by-step explanation:
Given the equation
We have to find the value of r for which the equation must be true.
solving the equation
Multiply both sides by -11
Therefore, the value of which makes the equation true.
<u>VERIFICATION:</u>
Putting in the equation
∵
L.H.S = R.H.S
Therefore, the value of which makes the equation true.
Step-by-step explanation:
For a quadratic equation y = ax² + bx + c, the vertex (the maximum or minimum point) is at x = -b/(2a).
1) y = -0.5t² + 2t + 38
The maximum is at:
t = -2 / (2 × -0.5)
t = 2
The maximum height is:
y = -0.5(2)² + 2(2) + 38
y = 40
The coordinates of the vertex are (2, 40). That means the missile reaches a maximum height of 40 km after 2 minutes.
2) y = -4.9t² + 12t + 1.6
The maximum is at:
t = -12 / (2 × -4.9)
t = 1.22
The maximum height is:
y = -4.9(1.22)² + 12(1.22) + 1.6
y = 8.95
The coordinates of the vertex are (1.22, 8.95). That means the missile reaches a maximum height of 8.95 m after 1.22 seconds.
3) y = -0.04x² + 0.88x
The maximum is at:
x = -0.88 / (2 × -0.04)
x = 11
The maximum height is:
y = -0.04(11)² + 0.88(11)
y = 4.84
The maximum height of the tunnel is 4.84 meters.
The maximum width is when y = 0.
0 = -0.04x² + 0.88x
0 = -0.04x (x − 22)
x = 22
The maximum width is 22 feet.
The answer is letter choice B
