1.The revenue for an amusement park can be modeled by R(x) = 80x -0.04x' where x is the number of people attending the park. The cost to operate the park can be
modeled by C(x) = 4.75x + 275. If profit is determined by subtracting cost from
revenue, which function models the profit of the amusement park?
A. P(x) = -0.04x + 75.25x – 275
B. P(x) = -0.04x + 75.25x + 275
C. P(x) = 0.047° - 75.25x - 275
D. P(x) = 0.04x+ + 75.25x + 275

i believe its b because this sounds familiar

Step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

17 1/3
