3.1 Q17
1 answer:
Here, you are looking at two numbers, x and y, such that 
, or, if you say that x is the larger of the two, simply 
. You are looking to minimize the value for 
. The smallest possible numbers are 
. You might initially be tempted to think that you should choose an infinitely negative number and a number 18 more than it; however, the product of two negative numbers is positive, so this would become an infinitely large number. Then, it might be tempting to say 18 and 0, because their product, after all, is zero. But it is possible to get a negative product with a positive and a negative number. The least product is when 
, and this will apply for any difference you choose, not just 18.
In sum, it's 9 and –9.
In sum, it's 9 and –9.

The triangle pay $32 more for that day than it paid per day during the first period of time.
Step-by-step explanation:
The given is,
Triangle Construction pays Square Insurance $5,980
To insure a construction site for 92 days
To extend the insurance beyond the 92 days costs $97 per day
Triangle extends the insurance by 1 day
Step:1
Insurance per day from the 92 days period,
Where, Total insurance for 92 days = $ 5,980
Period = 92 days
From the values, equation becomes,
= $ 65 per day
Step:2
Insurance per day after the 92 days,
= $ 97
Amount Pay for that day than it paid per day during the first period of time,
= $32
Result:
The triangle pay $32 more for that day than it paid per day during the first period of time, if the Triangle Construction pays Square Insurance $5,980 to insure a construction site for 92 days and to extend the insurance beyond the 92 days costs $97 per day.
