Answer:
The value of this investment at the end of the 5 years is of $662.5.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Dina invests $600 for 5 years at a rate of 2% per year compound interest.
This means that
. Thus



Calculate the value of this investment at the end of the 5 years.
This is A(5). So

The value of this investment at the end of the 5 years is of $662.5.
Answer:
13)

15) 
16) 
Step-by-step explanation:
Answer:
B (6, 8)
C (1, 5)
see attached diagram (qu 1 is blue, qu2 is red)
Step-by-step explanation:
1.
A = (2, 3)
If B is 4 right and 5 up from point A, then
B = (2 + 4, 3 + 5) = (6, 8)
2. C = (9, 7)
If D is 8 left and 2 down from point C, then
C = (9 - 8, 7 - 2) = (1, 5)
