The average salary is $18,725
To find the answer add up each job's salary then divide by the number of jobs.
28,700 + 18,600 + 14,66 + 13,00 = 74,900
Then divide 74,900 by 4 ( added 4 numbers )
Answer:

Step-by-step explanation:
This is horizontal parabola.
It has a directrix at x=-6.
The vertex is (0,0).
The focus is (6,0)
The equation of this parabola is of the form

Where (p,0) is the focus
By comparison, p=6
Therefore the equation of the parabola is

This implies that

3x1000+2x100+4x10+6x1+7x(1/10)+8x(1/100)
Answer:
see explanation
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = width × length
let width be w then length is 2w + 3 ( 3 more than twice the width ), then
A = w(2w + 3) ← distribute
= 2w² + 3w
When w = 4 , then
A = 2(4)² + 3(4)
= 2(16) + 12
= 32 + 12
= 44 ft²
