Answer:
c
Step-by-step explanation:
I think its c
I'm not sure
First, since the building is 5.5 inches and the scale is 1 inch for 8 feet, you would multiply 5.5* 8 to get 44 feet.
Answer:
Step-by-step explanation:
The 
-intercept of a line is the value when 
. In the equation 
, we can solve for its equation when we plug in .
Solving for when :
.
So the -intercept of the equation is 
.
To find what equation has the same -intercept, we can do the same process for each equations given by the choices. However, I can see that the equation, , has the -intercept. If in doubt, you can check for the solution below or solve each equations for yourself.
Solving for when :
Answer:
Step-by-step explanation:
The x intercepts are 0 and
1000 - 2x = 0 given condition
1000 = 2x Divide by 2
500 = x
So the two intercepts are 0,0 and 500,0
The intercepts mean that for (0,0) the phone company hasn't charged anything, yet. For 500,0 the phone company can sell a single phone -- not when they cost 500 dollars apiece.
The answer to the B part is completing the square.
r(x) = - 2x^2 + 1000x
r(x) = -2(x^2 - 500x )
1/2 ( 500) = 250
250^2 is what you put inside the bracket's to complete the square.
r(x) = - 2(x^2 - 500x + 250^2) + 2*250^2
r(x) = -2(x - 250)^2 + 2*62500
r(x) = - 2(x - 250)^2 + 125000
They should sell their phones at 250 dollars a piece. The total revenue is 125000. Your graph shows exactly the same thing.
