To determine the units needed to have the lowest cost, we need to do minimization of the equation of cost. We get the first derivative of the equation and equate it with zero. Then, determine the value of x.

<span>C = 0.25x2 - 80x + 30000
C' = 0.5x - 80 = 0
x = 160 units

Hope this answers the question.</span>

Help please I am very confused
Helga [31]

The sides of the triangle occur in a ratio of 4 : 7 : 2, so if <em>x</em> is some positive number, then we can write each side's length in terms of <em>x</em> as 4<em>x</em>, 7<em>x</em>, and 2<em>x</em>.

The perimeter is 299 yd, so

4<em>x</em> + 7<em>x</em> + 2<em>x</em> = 299 yd

13<em>x</em> = 299 yd

<em>x</em> = (299 yd) / 13

<em>x</em> = 23 yd

Then the sides of the triangle have lengths of

4<em>x</em> = 4 • 23 yd = 104 yd

7<em>x</em> = 7 • 23 yd = 161 yd

2<em>x</em> = 2 • 23 yd = 46 yd

"Median" here refers to the side length between the shortest and longest sides, so the answer would be 104 yd.

Please help me asap I will extra points show work it is surface area of prisms thank you
lutik1710 [3]
Okay, the easiest way (I personally) find surface area is to find the area of each face [L x W (OR H)] and then add all of the areas together.


Question 1)  The Area of 1 of the faces is 4, because 2 x 2 is 4. 
Since there is 6 faces, do 6 times 4, or 24^{2} feet in total.
