The problem can be represented by the the exponential growth formula which is :

Where: t ⇒ time , A ⇒ initial amount , r ⇒ rate of increase
P(t) ⇒ predicted amount at the end of t.
For the given problem:
initial amount = A = $278,640
<span>predicted increase in value per year = 4% =0.04
</span>
<span>∴ r = 1 + 0.04 = 1.04
</span>
<span>for t = 18 years
</span>
∴

<span />
Rounding to the nearest dollar ⇒ ∴ P(t) = <span>564,474
</span>
So, the predicted value of David's home in 18 years = $564,474
So, The correct option is <span>
$564,474</span>
This would be a Quintic Trinomial; it has a degree of 5 and 3 terms.
Answer:
(3,4)
Step-by-step explanation:
A function can't have the x repeat so the only possible answer is (3,4)

Answer:
It will take 8 years.
Step-by-step explanation:
If the plant is already 14 inches and you want it to grow up to 38, then we subtract 14 from 38 and then divide the answer by 3 because in each year the plant will grow 3 inches, so then you get 8, which is the numbers of years.
38 - 14 = 24
24/3 = 8
