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

Which property of polynomial addition says that the sum of two polynomials
ArbitrLikvidat [17]

Answer:

The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.

Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.

In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.
