Answer:

<u>Given</u>:

  • R(x) = 59x - 0.3x²
  • C(x) = 3x + 14

<u>Find the following</u>:

  • P(x) = R(x) - C(x) = 59x - 0.3x² - 3x - 14 = -0.3x² + 56x - 14
  • R(80) = 59(80) - 0.3(80²) = 2800
  • C(80) = 3(80) + 14 = 254
  • P(80) = 2800 - 254 = 2546

What's the area of this yellow surface? pick one of the options.
Oksi-84 [34.3K]
28 in^2

Divide shape into one rectangle and two squares:

Area of rectangle:
10 x 2 = 20 in^2

Area of one square:
2 x 2 = 4 in^2

Multiply that by 2 because we have 2 squares similar in size:
4 in^2 x 2 = 8 in^2

Add the area of the rectangle and two squares:
20 in^2 + 8 in^2 = 28 in^2

Have a nice day
Hope this helps!

Why won’t anyone answer my questions argh! how do you draw starlight line graphs
Oduvanchick [21]
The table tells us that the x coordinate. It also tells us that y is always x + 1.

For #1 you plot the coordinate (0, 1).
0 (the x coordinate) is given to us already.
1 (the y coordinate) is needed to be found by the equation.
You would then need to fill in the equation given with the x coorident. 
y = 0 + 1 
Then, solve for y.
0 + 1 = 1
The y coordinate is 1
Go to the horizontal line (x) and find 0.
Then go to the veridical line (y) and find 1.
Then match up the the x and y to plot the coordinate.

You would continue with this equation with the rest of the xs. 

This is a hard concept to explain in just words, so feel free to comment with any more questions. :D

If I cut 2/3 of a pie and put the big piece on my plate. Then eat 1/4 of the piece. What fraction of the original pie did I eat.
Hunter-Best [27]
If you took \frac{2}{3} of a pie then only ate \frac{1}{4} of that slice, you ate \frac{1}{4} of \frac{2}{3}.

\frac{2}{3} * \frac{1}{4} = \frac{2}{12}

Simplify.

\frac{2}{12} = \frac{1}{6}

So, you ate 1/6 of the pie.
