Answer:
The length of AP will be 14 units.
Step-by-step explanation:
As P is the centroid of ΔABC as shown in question figure.
As the side AB of the triangle has the midpoint D, the side AC of the triangle has the midpoint F and the side BC of the triangle has the
midpoint E.
Hence, CD, BF and AE being medians of ΔABC.
The point of intersection of these medians will be the centroid of the triangle. Hence, P is the centroid of ΔABC
According to rule, the centroid point of the triangle ΔABC divides each median into two segments in the ratio 2 : 1.
So,

As the value of AE = 21
So,

AP = 14
So, the length of AP will be 14 units.

Answer:
domain:

range:
![( - \infty ,4]](https://tex.z-dn.net/?f=%28%20-%20%20%5Cinfty%20%2C4%5D)
equation:

Step-by-step explanation:
domain is all X values and the X values will extent till infinity in both negative and positive direction, the range is all y values and the y value will go from negative infinity all the way to 4, where the graph stops.
The equation y=0.02x+250 gives the weekly income y in terms of sales x.
Step-by-step explanation:
Given,
Weekly salary of real estate agent = $250
Commission rate = 2%
Let,
x be the sales per week.
y be the total weekly income.
Amount of commission = 2% of sales per week
Amount of commission = 
Amount of commission = 0.02x
Total weekly income = Amount of commission + Weekly salary

The equation y=0.02x+250 gives the weekly income y in terms of sales x.
