Answer: n > -9
Step-by-step explanation:
3+2n > -15
2n> -18
n > -9
It is 35% because you need to divide 21 out of 100 then multiply the answer you get by 7
Answer:
First of all look at the graphs that have been plotted then at your equation that is given. You see the x and ys there and find the answer
Your picture has several issues.
- x is not defined. It appears to be the number of apartments rented.
- R(x) is defined two different ways. The first way, it looks like it is the revenue from a single apartment. The second way, it looks like it is the revenue from the entire apartment complex.
- The derivative is in error. It should be -20x +2000. In any event, this is not the derivative you want. You're not trying to maximize revenue; you're trying to maximize profit.
- It might be useful to write an equation for profit: P(x) = R(x) -200x = -10x² +1800x. Then when you go to maximize it, your derivative will be P'(x) = 0 = -20x +1800 ⇒ x = 90.
Your answer is correct, but the path you followed to get there has a few potholes.
The cubic inches left is 20.05 cubic inches.
<h3 /><h3>Description of the glass </h3>
A glass has the shape of a cylinder. In order to determine which glass is left, the volume of the glass has to be determined. Then what is drank would be subtracted from the volume of the glass.
<h3>
Volume of the cylinder. </h3>
Volume of a cylinder = nr^2h
- n = 22/7
- r = radius= 2.5 / 2 = 1.25
22/7 x 1.25^2 x 5 = 24.55 cubic inches
<h3>Determination of what is left </h3>
24.55 - 4.5 = 20.05 cubic inches
