Revenue = Sales Volume (x) times Price. Price depends on volume sold: the more you are willing to sell per week, the lower your average price will have to be to get them all sold.

<span>eg, if there are a fixed number of buyers with a variety of incomes, then you might be able to sell the first 10 per month for £30 each through the up-market High Street jeweller. If you want to sell an extra 10 per month you might have to reduce the price to £15 and sell them through Asda/WalMart. And to move another 10 per month you may have to sell them from a street stall at £5 each! </span>

How do you go from Vertex To standard Form?

Lynna [10]

The vertex form:

$y=a(x-h)^2+k$

The standard form:

$y=ax^2+bx+c$

$y=a(x-h)^2+k\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\y=a(x^2+2xh+h^2)+k\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\y=ax^2+2ahx+ah^2+k$

HELP MATH ANSWER QUESTION

Rom4ik [11]

Answer:

x = 84 , y = 168

Step-by-step explanation:

$Sin 60 = \frac{opposite side}{hypotenuse}\\\\ \frac{\sqrt{3}}{2}= \frac{AB}{BC}\\\\ \frac{\sqrt{3}}{2} = \frac{84\sqrt{3}}{y}\\\\Cross\ multiply ,\\\\y*\sqrt{3} =2*84 \sqrt{3}\\\\y= \frac{2*84*\sqrt{3}}{\sqrt{3}}\\\\y=168$

$Cos\60 = \frac{adjacent}{hypotenuse}\\\\ \frac{1}{2}= \frac{AC}{BC}\\\\ \frac{1}{2}= \frac{x}{168}\\\\ \frac{1}{2}*168=x\\\\x= 84$

A football team starts on the 10 yard line moving toward the 50 yard line so they can score on the other side of the field. In t

sergiy2304 [10]

Answer:

16 yard line

Step-by-step explanation:

The football team is starting on the 10 yard line. In the first play, they move up to the 24 yard line. Then in the second play, they go back to the 12 yard line since they lost 12 yards. Then in the third play, they gain 4 yards so you add 4 to 12. They end up at the 16 yard line after the third play. This means that they're going to start their fourth play at the 16 yard line.
