Answer:

Step-by-step explanation:

Ok, well the first thing you need to do is make -4/13 have the same numerator as 9/26. Thankfully, 26 is a multiple of 13, so that step is easy:

-4/13 -> -8/26

Then you can add them together with ease.

9/26 + -8/26 = 1/26

Adding a negative number to anything is the same thing as subtracting.

Rewrite 81 as 3 to some power.

NikAS [45]

First, let's find all the factors of 81:

81/3=27
27/3=9
9/3=3
3/1=1

So the factors of 81 are 3,3,3,3, (the numbers by which we divided here).

This means we can write down 81 as 3*3*3*3 or $3^{4}$ - which is the answer to the question! (three to the power of 4)

The cost of producing x units of a product is C dollars, where C is given by the function C = 0.25x2 - 80x + 30000. (See the gra

Nat2105 [25]

From calculus, to determine the maxima or minima of the graph, get the derivative of the equation and equate to zero. So, we derive first the equation of the graph and equate to zero.

C = 0.25x² - 80x + 30000
dC/dx = 0 = 0.5x - 80 + 0
0.5x = 80
x = 80/0.5
x = 160 units

The minimum cost (although not asked) is:

C = 0.25(160)² - 80(160) + 30000
C = $23,600

The answer is 160 units.
