If the cost, C(x), for manufacturing x units of a certain product is given by C(x) = x2 – 15x + 34
find the number of units manufactured at a cost of $8350.

99 units.

Step-by-step explanation:

The cost function for manufacturing x units of a certain product is:

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

Subtract 8350 from both sides:

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

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

Simplify:

Evaluate:

Therefore, our solutions are:

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

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

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

55 because 55 + 55 = 110 good luck babe
