Answer:
The vertex is the point (6,-31)
Step-by-step explanation:
we have

This is a vertical parabola open upward
The vertex represent a minimum
Convert to vertex form
Complete the square


Rewrite as perfect squares
-----> equation in vertex form
therefore
The vertex is the point (6,-31)
Answer:
Hence the correct option is option d.
Explanation:
We can 95% confident that between 28.1% and 39.2% of all rental property owners own a property by the water.
Here correct option for interpretation of the 95% confidence interval. The remaining options are about probabilities and sample proportions.
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.

Determine the number of pints of each to make 21 of green paints
First, calculate the total ratio.


The blue and the yellow pint can be represented individually as:


Number of blue paint calculated last week is:







I’m pretty sure it’s 86, because you need to subtract 2 from the first side then you have 86 = X
