At day 7, the four-day moving average for the price of the stock would be $58.25.
<h3>What is the four-day moving average at day 7?</h3>
This can be found as:
= (Day 7 price + Day 6 + Day 5 + Day 4) / Number of days
Solving gives:
= (59 + 55 + 59 + 60) / 4
= 233 / 4
= $58.25

X²+3x-21=0
1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2
2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21
Answer: the product of the 2 solutions of this equation is -21

Answer:
Step-by-step explanation:
The marginal cost function, C'(x), is the derivate of the cost function, C(x).
Therefore, we can obtain the cost function by finding the integral of the marginal cost function:
Where 'a' is a constant and represents fixed costs. If fixed costs are $3,000, the cost function is:
