Answer:
$1136.60
Step-by-step explanation:
The formula for exponential growth is f(x) = a(1 + r)^x where a is the initial value, r is the growth rate, and x is the number of time intervals.
We know that Mr. Paris starts with an $1800 initial value, so we can substitute that into the equation:
f(x)=1800(1 + r)^x
We also know the time intervals is 6 months. So that can be substituted as well:
f(x)=1800(1 + r)^6
They told you that the growth rate is 8.5%, which is 0.085 of 1.
f(x)=1800(1 + 0.085)^6
Add the 2 values in the parentheses and you get 1.085
f(x)=1800(1.085)^6
Now solve.
Order of operations requires you to raise 1.085 to the 6th power before multiplying by 1800. So then you have this:
1800(1.63146751) = 2936.64152. That rounds to 2936.60
So $2936.60 is the total amount of money in the bank account, but were looking for the interest earned, which is the difference between the end value and the initial value.
$2936.60 - $1800 = $1136.60
Answer:C
Step-by-step explanation:
The correct proportion of the corresponding sides is 2 : 3
<h3>How to determine the proportion?</h3>
From the question, we understand that the shapes are similar.
This means that:
Ratio = GHIJ : KLMN
From the figure, we have:
GH = 6 and KL = 9
So, we have:
Ratio = 6 : 9
Simplify the ratio
Ratio = 2 : 3
Hence, the correct proportion of the corresponding sides is 2 : 3
