<u>Key skills needed: Simple Interest Formula, Operations ( +, - , x , / )</u>
1) To understand this problem, you need to know the simple interest formula.
A = P(1+rt)
A is the amount
P is the principal
R is the interest rate as a decimal
T is the time in years
2) The 1st thing we need to do is convert the interest rate into a decimal. We have 14%. To convert into decimal form, we divide it by a 100, or move the decimal 2 places to the left. This is 0.14 --> So r=0.14
3) Next we use the formula:
A = 1,010(1+ 0.14(8))
- We first do 0.14(8) which is 1.12 and then add it to the 1 value, so you will get --> A = 1,010(2.12)
- Multiply and you will get A = $2,141.20
- To find the interest earned, you subtract this by the original amount, so $2,141.20 - $1,010 which would be $1,131.20
This means $1,131.20 is your answer.

Hello!
You put -1 in for x
F(-1) = (-1)^5 + (-1 + 3)^2
F(-1) = -1 + (2)^2
F(-1) = -1 + 4
F(-1) = 3
The answer is 3
Hope this helps!
Answer:
12
Step-by-step explanation:
<h2>8 unit tiles should be added</h2>
Step-by-step explanation:
Function given is 
. We wish to add more unit tiles to the function so that it becomes a complete square.
Since the given function is of order 2, the side of the square will be order 1. Let us assume a general order 1 expression 
to be the side of the square.
As the function forms the square after adding some 
unit tiles, 
From comparision, 
∴ 8 more unit tiles are required to complete the square.
