At the start of 2014 Tim's house was worth 100,000.

Novay_Z [31]

For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
Substituting values we have:
y = 100000 * (1.10) ^ 4
y = 146410
Answer:
the value of his house at the start of 2018 is:
y = 146410

Answer:

(x-y^2)(x^2 +xy^2 +y^4)
(a^2 +b)(a^4 -a^2b +b^2)
(m^3-n)(m^6 +m^3n +n^2)
(p+k^3)(p^2 -pk^3 +k^6)
(a^2+b^3)(a^4 -a^2b^3 +b^6)
(x-y)(x^2 +xy +y^2)(x^6 +x^3y^3 +y^6)

Step-by-step explanation:

In every case, the factorization makes use of the standard form for factoring the sum or difference of cubes:

a^3 +b^3 = (a +b)(a^2 -ab +b^2)
a^3 -b^3 = (a -b)(a^2 +ab +b^2)

1. a=x, b=y^2. Use the formula for the difference.

2. a^2 ⇒ a, b = b. Use the formula for the sum.

3. a=m^3, b=n. Use the formula for the difference.

4. a=p b=k^3. Use the formula for the sum.

5. a^2 ⇒ a, b^3 ⇒ b. Use the formula for the sum.

6. a=x^3, b=y^3. Use the formula for the difference. When you do, the first factor is the difference x^3 -y^3, which can be factored using the difference formula again with a=x, b=y.
