Suppose a farmer wants to fence off a rectangular area with three sides of a rectangle, using a river as the fourth side. He has

100 yards of fence to use. Let x denote the length of the side of the rectangle parallel to the river. Find a formula for the function A(x) that gives the area as a function of x. What is the domain of this function based on the formula and what is it based on the context of the problem?

A = Area
x = Side Parallel to the river.

a = (\frac{x}{2}) \times x

Which in your context results to:

x = 100 \div 2
1250 = ( \frac{50}{2} ) \times 50

Area = 1250 yards squared

Edgar purchased a home for $182,100 to home appreciates about 3.5% each year what is the value of the home after 12 years
olasank [31]

Answer:

the value of the home after 12 years =$275,165.60

Step-by-step explanation:

To find value of appreciation after 12 years

We apply exponential growth formula

y=a(1+r)^x

Where a represents the initial amount (purchased amount)

a= 182,100

r = rate of interest ( appreciation percentage) = 3.5% = 0.035

x  represents the time period= 12 years

Plug in all the values

y=a(1+r)^x

y=182100(1+0.035)^12

y= 275165.6025027724  

y=$275165.60
