Answer:28.2753
Step-by-step explanation:
You have two choices.
The minimum possible cost to operate your bat factory for a day is $390,
and there are two quantities of bats that both cost that much.
One possibility:
Produce no bats at all per day. Zero. Nada. None.
Cost = 0.06(0)² - 7.2(0) + 390 = $390 per day.
The other choice:
Produce 120 bats per day.
Cost = 0.06(120²) - 7.2(120) + 390
= 0.06(14,400) - 7.2(120) + 390
= 864 - 864 + 390
= $390 per day.
If you produce any other number of bats in a day ... more than zero
but not 120 ... then it will cost you more than $390 to operate the factory
that day.
It should be the 2nd or 4th answer, i’m not COMPLETELY sure. I’m positive it’s the 4th answer
We want to find one-half of the reciprocal of 7/sqrt(98). Let's write down an expression for this:
We can rewrite 98 into 
The square root of 49 is 7
This should be your answer. Let me know if you need any clarifications, thanks!
