Since x can be any value as long as the denominator equals 0 (it doesn't matter if it's positive or negative), we have to figure out when x^2=0, which is when x=0. Therefore, the domain is (-inf, 0) U (0, inf)
Answer:

a) $4110
Step-by-step explanation:
Let x represent number of rain coats and C(x) represent total cost to produce new line of rain coats.
We have been given that the fixed costs of $570 to set up for production, and variable costs of $30 per jacket.
The cost of x jackets would be
.
The total cost of x jackets would be variable cost of x jackets plus fixed costs that is $570.
Therefore, the total cost of producing x rain coats would be
.
To find the total cost of producing 118 rain coats, we will substitute
in the above equation as:



Therefore, the total cost of producing 118 rain coats is $4110 and option 'a' is the correct choice.
So you have to ask yourself “how many 25 minute sessions are there in 6 hours?” First you have to convert 6 hours to minutes. 6 hours = 360 minutes. Next divide that number by 25. 360 divided by 25 is 14.4. Now you know that there are 14.4 sessions of 25 minutes in 6 hours. Because the Ferris wheel can have 50 people in 25 minutes, you can multiply 14.4 times 50. The answer is 720 people.
Hello there! So, 1/4 is equivalent to 0.25, which is 25% in percent form. 0.5 is 50% and 0.2 is 20% in percent form. 50 + 20 + 25 is 95. 100 - 95 is 5. Issac can use 5% of the minutes on the cell phone plan. The answer is D: 5%.
