Write the equation of the circle with center (3, 2) and radius r = 7. Use the ^ key for the exponents. Write your answer as the example:
(x - 4)^2+(y+8)^2=25
If Keith is represented by x, and Joe is three less than Keith, Troy is represented by x-3.
Then, we know that Joe exercises for twice the amount of time as Troy, we multiply the expression for Joe by two.
Keith = x
Troy = x-3
Joe = 2(x-3)
The standard compound interest formula is
Future value after x years with an annual interest of i
=Present Value (1+i)^x [which is an exponential function]
for given present value of $360. interest=0.03 (3%) and a total of x years, above equation reduces to
Future value after x years
=360(1.03^x)
