Answer:
A(x) = x(200-x)
Step-by-step explanation:
400 feet of fencing to enclose a rectangular dog exercise pen means the perimeter of rectangle is 400 feet
If x is length and y is breadth. Perimeter is given by :
P = 2(x+y)
400 = 2(x+y)
⇒ (x+y) = 200 .....(1)
y = 200-x
Area of a rectangle is given by :
A = xy
A(x) = x(200-x)
Hence, the area as a function of length of rectangle is x(200-x).
Simplifying the expression would be 19.76.
The answer is 8
Explanation if you care lol:
For the denominators (4, 8) the lowest common denominator is 8
The number of years it would take sales to reach $1,750,000 is 14.65 years.
<h3>What is the number of years?</h3>
The formula that can be used to determine the number of years it would take for the sales to reach $1,750,000 is:
Number of years : In (FV / PV) / r
Where:
- FV = future level of sales - $1,750,000
- PV = present level of sales = 850,000
- r = rate of growth - 4.931998%
Number of years : In ($1,750,000 / 850,000) / 0.04931998
Number of years : In (2.06) / 0.04931998
Number of years : 14.65 years
