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.

Help needed ASAP will give brainliest AND 5 STARS RATE

STALIN [3.7K]

Answer:

A or the first answer is correct

Step-by-step explanation:

3650 - 2000 = 1650

1650 / (divided by) 150 = 11

you can also check your work by doing 150 *(times) 11 = 1650

1650 + 2000 = 3650

6 math geniuses help please!! math

Answer:

Step-by-step explanation:

Begin with Euler's formula. I am assuming youre aware of this if youre taking complex algebra? You can prove Euler's formula by doing a Maclaurin expansion of cosine, sine, and e^x. Euler's formula states that:

$e^{ix}=cos(x)+isin(x)$

We can put the first complex number in exponetial form by noticing the input is 2pi/3. The second complex number has an input of pi/3. Therefore:

$z_1=8e^{i(2\pi /3)}$

$z_2=0.5e^{i(\pi /3)}$

Then:

$\frac{z_1}{z_2} =\frac{8e^{i(2\pi /3)}}{0.5e^{i(\pi /3)}}$

Simplify the coefficients to get:

$\frac{z_1}{z_2} =\frac{16e^{i(2\pi /3)}}{e^{i(\pi /3)}}$

When you divide exponentials, you subtract the exponents. Therefore:

$\frac{z_1}{z_2} =16e^{i(2\pi /3)-i(\pi /3)}=16e^{i(\pi /3)$

Put it back into trigonemtric form using Euler's formula:

$16e^{i(\pi /3)}=16cos(\pi /3)+i16sin(\pi /3)$

Cosine of pi/3 is 0.5, and sine of pi/3 is square root of 3 over 2. We have:

$16e^{i(\pi /3)}=16cos(\pi /3)+i16sin(\pi /3)=16*0.5+16*\frac{\sqrt{3} }{2} *i=8+8\sqrt{3} i$

If two expressions have the same factor and base , what happens to the exponents when the expressions are multiplied

Amanda [17]

When two exponents have the same base or factor such as 3^6 and 3^8 and are multiplied, the exponents are added together. The answer would be 3^14.

Can I please get Help with this math problem please

kifflom [539]

Answer:

AB=16

BC=15

AC=12

PQ=12

QR=12

PR=19

Step-by-step explanation:

well you know that the perimeter is the sum of all sides

so we have

$(2x)+(2x+4)+(2x+3)=(2x)+(2x)+(3x+1)\\\\2x+2x+4+2x+3=2x+2x+3x+1\\\\(2x+2x+2x)+(4+3)=(2x+2x+3x)+(1)\\\\6x+7=7x+1\\\\6x+7-1=7x\\\\6x+6=7x\\\\6=7x-6x\\\\x=6$
