Answer:
the ending balance is $531.51
Step-by-step explanation:
The computation of the ending balance is shown below:
= Opening balance + all deposits - all withdrawls
= $500 + $100 + $250 + $300 - $400.32 - $100 - $55.55 - $62.62
= $531.51
hence, the ending balance is $531.51
Answer:
6
Step-by-step explanation:
Given : g(x) = and h(x)=2x-8.
g*h(x) =(2x-8).
We have square root(x-6) in composite function f*h(x).
So, we need to find the domain, we need to check for that values of x's, square root(x-4\6) would be defined.
Square roots are undefined for negative values.
Therefore, we can setup an inequality for it's domain x-6≥0.
Adding 4 on both sides, we get
x-6+6≥0+6.
x≥6.
Answer:
The employee would earn $320 for a 40-hour work week.
Step-by-step explanation:
Given
- Total Earning amount = $72.00
- Total Time taken = 9 hours
To determine
We have to find the employee's earning earn for a 40-hour work week.
<u>First Step</u>
Determining the hourly rate
In order to determine the hourly rate, the first step we need to do is to divide the earning amount by the total number of hours.
Hourly rate = Total Earning amount / Total Time taken
= $72.00 / 9 hours
= $8.00 per hour
<u>Second Step</u>
Determining the employee's earning earn for a 40-hour work week.
As we have already determined that employee is earning $8.00 per hour.
i.e.
- Hourly rate = $8.00 per hour
In order to determine the employee's earning for a 40-hour work week, all we need is to multiply the hourly rate i.e. 8 with 40.
Thus,
Earning for 40-hour work week = Hourly rate × 40
= 8.00 × 40
= $320
Therefore, the employee would earn $320 for a 40-hour work week.
since the point (4,13) is on the circle, then the distance from the center to it, is the radius of the circle.
