A company sells widgets. The amount of profit, y, made by the

vfiekz [6]

Answer:

846.06 units

Step-by-step explanation:

The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation as follows :

$y = -4x^2 + 183x- 1247$ ...(1)

We need to find out the maximum amount of profit the company can make.

For maximum profit put dy/dx = 0

So,

$\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87$

Put x = 22.87 in equation (1). So,

$y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06$

So, the maximum profit is 846.06 units.

If the perimeter of a rectangular picture frame must be less than 180 in, and the width is 26 in, what must the height h of the

valentinak56 [21]

You would form this inequality:

52 + 2x < (or equal to) 180

Then, solve as you would in an ordinary equation.

Subtract 52 from both sides of the sign. 180 - 52 = 128.

So, 2x is less than or equal to 128.
Divide 128 into two to get 64.

The height of the frame must be 64 inches.

When making sugar skulls we made 5 small ones for every 7 large ones we made. If we made 132 sugar skulls altogether, how many w

Zina [86]

Okay so first,

Confirm: Every time we have 7 large sugar skulls, that also makes 5 large sugar skulls. So if you have 132 <u>ALTOGETHER</u>, then you'd need to do some multiplication/division. First, divide 132 by 5, that equals 26 small sugar skulls. Lastly, 132 ÷ 7 = 18 large sugar skulls. So there are 26 small sugar skulls and 18 large sugar skulls.

(I hope that was right, I tried my best :)
