ANSWER
• Circumference: 18.84 ft
,
• Area: 28.26 ft²
EXPLANATION
The circumference of a circle of radius r is,

In this case, the radius is r = 3 ft and we have to use 3.14 for π,

Hence, the circumference of this circle is 18.84 feet.
The area of a circle of radius r is,

In this case, r = 3 ft and π = 3.14,

Hence, the area of this circle is 28.26 square feet.
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.
If we use the surface of the water as our frame of reference, then Christy's vertical position could be represented by -12 ft.
Answer:
-7
Step-by-step explanation:
first you plug in f(3) in the x so -2(3)= -6
then -6 - 1 = -7
Answer:
1) 10mn - 10×m×n
2)15m - 15×m
10×m×n×+15×m
=10mn+15m
factorize
common number(divisor) = 5
5m(2n+3)
5m*2n=10mn
5m*3=15m
