Answer:
The first answer is correct.
Step-by-step explanation:
Line 5 says that the reason is due to substitution
Line 3 says m∠ SQT equals 180°
If we substitute 180° into the spot for m∠ SQT in line 4, we get solution option 1
Answer:
i would say its b
Step-by-step explanation:
If 3 =

, then we know 9 =

because 9 is 3 squared.

can be simplified to

So now we know

=

·

Since

and

have the same base, we can express it as a single term by adding the exponents together.
So the answer is C)
Answer:
$500?
Step-by-step explanation:
Answer:
$302,500
Step-by-step explanation:
If cost (C) = $7, then Sales (S) = 37,500 units
If cost (C) = $15, then Sales (S) = 17,500 units
The slope of the linear relationship between units sold and cost is:

The linear equation that describes this relationship is:

The revenue function is given by:

The cost at which the derivative of the revenue equals zero is the cost that yields the maximum revenue.

The optimal cost is $11, therefore, the maximum revenue is:
