Profit is always calculated as revenue minus expenses. If a company’s expenses were $10 million, write an equation that expresse

ivann1987 [24]

The equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) is P = R - 10

The profit is $15 million when revenue is $25 million

Step-by-step explanation:

The formula of the profit is P = R - E, where

R is the revenue
E is the expenses

If a company’s expenses were $10 million, wee need to write an equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) and then find the profit when revenue is $25 million

∵ P is the profit in millions of dollars

∵ R is the revenue in millions of dollars

∵ The expenses E were $10 million

∵ Profit = Revenue - Expenses

∴ P = R - 10

The equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) is P = R - 10

∵ The revenue R = $25 million

∵ P = R - 10

- Substitute the value of R in the equation

∴ P = 25 - 10

∴ P = 15

∴ The profit is $15 million

The profit is $15 million when revenue is $25 million

Answer:

Answer is below

Step-by-step explanation:

Factor left side of equation.

$(z+2)(z-3)=0\\$

Set factors equal to 0.

$z+2=0 or z-3=0\\\\z=-2 \\Or\\ z=3$

Which one of the triangles shown is the image of the other triangle after dilation?What are the coordinates of the center of dil

Tanya [424]

Answer:

a) ΔF'G'H' is the image of ΔFGH

b)Center of dilation (7,-1)

c) Scale factor: $\frac{1}{2}$

Step-by-step explanation:

Question a

Since the smaller triangle is named F'G'H', it means that, it is the image of triangle FGH.

Question B.

To find the center of dilation, draw straight lines through any two corresponding points.

The straight lines will meet at (7,-1).

This is called the center of dilation.

See graph in attachment.

Question c

The scale factor of the dilation is given by;

$k=\frac{|F'G'|}{|FG|}$

$k=\frac{\sqrt{(4-5)^2+(1-5)^2}}{\sqrt{(3-1)^2+(3-11)^2}}$

$k=\frac{\sqrt{1+16}}{\sqrt{4+64}}$

$k=\frac{\sqrt{17}}{\sqrt{68}}$

$k=\frac{\sqrt{17}}{2\sqrt{17}}$

$k=\frac{1}{2}$
