Answer:
99 units.
Step-by-step explanation:
The cost function for manufacturing <em>x</em> 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.
They can be equal if the absolute value of b is 1.
2.89 rounded is 3 2.82 rounded is 2.80 which = 2.8 you minus 3-2.8 it = 0.2

Complete Question:
The temperature doubled. Evaluate when t = 32 degrees.
The value of the expression when t = 32 degrees is degrees
Answer:
64 degrees
Step-by-step explanation:
Given

Required
Determine the value of t when it doubles
To do this, we simply multiply the current temperature by 2.
So:
becomes


<em>Hence, the temperature when it doubles is 64 degrees</em>
