Consider these specific values of x.
For example, if x=10, then <span>C(10)=16(10)+36,000=160+36,000=36,160 (say $)
and R(10)=18*10=180.
So if only 10 units are produced, the total cost is 36,160, while the revenue is only 180 (again, say $.)
If, for example, x=1000, then we can calculate
</span><span>C(1000)=16*1000+36,000=16,000+36,000=52,000
and
R(1000)=18*1000=18,000.
This suggests that with higher values of x, we can get to a particular point where the Cost and Revenue are the same. To find this point, we set the equation:
C(x)=R(x),
which gives us that particular x at which both </span>C(x) and R(x) give the same value.
Thus, we solve <span>16x+36,000=18x. Subtracting 16x from both sides 2x=36,000, then x = 36,000/2=18,000.
Answer: 18,000

Answer:
Let f be a function. If any horizontal line intersects the graph of f more than once, then f does not have an inverse. An absolute value function (without domain restriction) has an inverse that is NOT a function. That's why an absolute value function does not have an inverse function。
A
D
B
False
I believe those are correct
Step-by-step explanation:
5x + 2(11 - x) = - 5
5x + 22 - 2x = - 5
3x = - 5 - 22
3x = - 27
x = -27 / 3
x = 9
Therefore x = 9 .
Answer:
sigma should be used
Step-by-step explanation:
Given that The mean length of time in jail from the survey was four years with a standard deviation of 1.9 years.
The above given is for sample of 27 size.
For hypothesis test to compare mean of sample with population we can use either population std dev or sample std dev.
But once population std deviation is given, we use only that as that would be more reliable.
So here we can use population std deviation 1.4 only.
If population std deviation is used we can use normality and do Z test
