Answer:
4 dollars or 13 dollars
Step-by-step explanation:
Revenue is the income or increase in net assets that a commercial organization have as a result of offering services.
Revenue is the product of selling price per goods and the number of goods sold. That is:
Revenue = selling price per goods * number of goods sold
Given the revenue function:
R=-n² +17n +200; where n is the increase in the original price of T-shirt.
Since the council wants to make a revenue of $250, hence:
-n² +17n +200 = 250
-n² + 17n - 50 = 0
Solving using a calculator gives:
n = $4 or $13 (to the nearest whole number)
Consider the cross-sectional right triangle shown in the figure.
One of its sides is the height of the pyramid, with length H. The other side is half of the square base, so its length is 81 m. The hypotenuse of this triangle is the height of one of the faces.
By right triangle trigonometry,

,
thus,

.

Required

For two functions f(x) and g(x) where f(x) and g(x)are inverse;

So, by comparison:

Answer:
y = 7x/5 - 5
Step-by-step explanation:
m = 7/5
y - 2 = 7/5(x - 5)
y - 2 = 7x/5 - 7
y = 7x/5 - 5
