The answer is ‘y=30’
i don’t really know how to explain it but multiply the first top number’-4x’ with all of the bottom numbers. Multiply the first number at the bottom ‘-10’ by all the numbers at the top.
-40x-20y=-140
-40x+28y=-100

c)
Step-by-step explanation:
For total cost function , average cost is given by i.e., total cost divided by number of units produced.
Marginal average cost function refers to derivative of the average cost function i.e.,
Given:
Average cost =
a)
At x = 50 units,
b)
Average cost =
c)
Marginal average cost:
Differentiate average cost with respect to
Take
using quotient rule,
Therefore,
Answer:
841.6 ft
Step-by-step explanation:
Solve this using the quadratic formula.
y=-16x^2+212x+139 becomes -16x^2 + 212x + 139. The x-value of the axis of symmetry is
-212
x = ----------- = 6.625 (This time measurement is in seconds.)
2(-16)
The maximum height reached by the rocket is the y value when x = 6.625 and is y(6.625) = 841.6 ft
