Answer:
<em>Question 7. Option B,</em>
<em>Question 8. Option C</em>
Step-by-step explanation:
<em>Question 7.</em>
Let us create a proportionality, and solve for the value of s, through cross multiplication;
<em>Question 8.</em>
We can solve this problem in a similar manner, through setting a proportionality and solving for the length of the shadow of the tree, which we can pose as x;
Answer: 1) The minimum price, in dollars, to avoid a loss = 22,
2) the maximum price in dollars , to avoid a loss = 53,
3) The price that results the maximum profit = 37.5 dollars
Step-by-step explanation:
Since the given function that shows the total profit,
Where x is the price of the product.
Since for avoiding the loss,
,
⇒
If
If
Thus, 53 ≥ x ≥ 22,
Therefore, the minimum price to avoid the loss = $ 22
And, the minimum price to avoid the loss = $ 53
⇒
Now, For maximum or minimum,
,
⇒
⇒
⇒
For x = 37.5, f''(x) is negative,
Thus, For the price of $ 37.5 dollars the company has the greatest profit.
