What do you need help on exactly?
To answer this question, we have the start-up costs of $ 52,000
A monthly inflation of $ 0 is assumed
Operating costs are $680
The daily gain is $960
For the Part A.
The inequality that this situation represents

So:

Where d represents the number of days.
For the Part B.
To start earning, you must replace all the initial investment and cover the expenses per day. The time that must pass for this to happen is obtained by clearing "d" from the inequality.

d> 185.71 days
Then, the sum of the net profits will be greater than the initial investment after 186 days of starting the business.
Answer: Density
This measurement tells you how packed in a substance is. The higher the density, the more the object weighs for a certain volumetric unit (such as a cubic meter). Eg: a cubic meter of feathers is likely to weigh less than a cubic meter of solid gold because the feathers have a lot more air in them as opposed to the gold which is more compact.
density = mass/volume is the formula you often use
0,-3
To work this out I would use the midpoint formula. (x1+x2)/2 , (y1+y2)/2
Therefore, (3+-9)/2 , (-4+0)/2
= -6/2. , -4/2
= -3 , -2
Now we know the half way point from AB, now we will use the same formula but instead of point B we will substitue the midpoint to work out the 1/4 point
Therefore, (3+-3)/2, (-4+-2)/2
=. 0/2, -6/2
=. 0, -3
Therfore the 1/4 way point from AB is 0,-3
Answer:
O A. g(x) = 2(x-4)(x + 7)
