If the cost, C(x), for manufacturing x units of a certain product is given by
Diano4ka-milaya [45]

Answer:

99 units.

Step-by-step explanation:

The cost function for manufacturing <em>x</em> units of a certain product is:

C(x)=x^2-15x+34

We want to find the number of units manufactured at a cost of $8350. Therefore:

8350=x^2-15x+34

Subtract 8350 from both sides:

x^2-15x-8316=0

This equation can be a bit difficult to factor, if even possible, so we can use the quadratic formula:

\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

In this case, a = 1, b = -15, and c = -8316. Thus:

\displaystyle x=\frac{-(-15)\pm\sqrt{(-15)^2-4(1)(-8316)}}{2(1)}

Simplify:

\displaystyle x=\frac{15\pm\sqrt{33489}}{2}

Evaluate:

\displaystyle x=\frac{15\pm183}{2}

Therefore, our solutions are:

\displaystyle x=\frac{15+183}{2}=99\text{ and } x=\frac{15-183}{2}=-84

We cannot produce negative items, so we can ignore the second answer.

Therefore, for a cost of $8350, 99 items are being produced.

2х - Зу = 32<br> x + 4у = -20<br><br><br> solve the system of equations
ANTONII [103]
Answer: x=68/11 and y=-72/11


Steps:

2(x+4y=-20)

2x+8y=-40

2x - 3y = 32
- 2x + 8y = -40

-11y=72

y=-72/11


x + 4(-72/11) = -20

x - 288/11 = -20

x=68/11

Minchanka [31]
I would use the formula
Initial x multiplier^time

So the initial is 7,500, the multiplier will be 1.03975 and then it would be to the power of 10 (time).

7500 x 1.03975^10 = $11,075.17
