Step-by-step explanation:
y=f(x)=3x find f(x) when x=0
f(x)=3x
f (0) = 3×0
=0
Answer:
24 customers per hour
Step-by-step explanation:
The service rate is given by the demand of customers per hour per employee divided by the labor utilization.
If there are two service counter employees on duty, the demand of customers per hour per employee is:

Answer:

Step-by-step explanation:
There are several ways to solve this quartic equation. But since the coefficients, they repeat a=1,b=2,c=1,d=2, but e=0, and they are multiple of each other, then it is more convenient to work with factoring as the method of solving it.
As if it was a quadratic one.

Answer:
cube root is what number can go into it 3 times
Step-by-step explanation:
for example, the cube root of 27 is 3, because you can times 3x3x3 and get 27. Another example is the cube root of 125 is 5, because you can times 5x5x5 and get 125.
