Answer:
D. A = πr^2
Step-by-step explanation:
The formula of the area of a circle is <u>A = πr^2</u>.
Question 1. It is graph 3 since the y-intercept in the equation is -2 and the y-intercept on the graph 3 is -2. It is also a quadratic function.
Question 2. It is graph two because the equation listed represents a quadratic function that is positive (graph opens up).
Question 3. It is graph 4 since the y-intercept is 2 and the only graph with that intercept is graph 4. Also, the equation represents a linear function.

Step-by-step explanation:
$7881.18
Step-by-step explanation:
Let the initial Investment be . The Interest is compounded on a monthly basis at 12% annual interest rate. After 17 years, the Investment amounts to $60,000.
As the annual interest rate is 12%, the monthly interest rate is 1%.
Since this is a compound interest problem, the total amount can be modeled as follows:
Here is the interest rate, i.e , and t is the number of time periods, i.e =
∴ Initial Investment = $7881.18
