<span>(x - h)² + (y - k)² = r²
is the equation of the circle with center (h, k) and radius r units.
Thus (x + 2)² + y² = 10 is the equation of a circle whose center is at the point (-2, 0) and having a radius of √10 units<u>

Answer:

Step-by-step explanation:
This is a compound interest formula expressed as:

Where:
is time in years
is the rate of interest
is the accumulated amount after n years
is the initial amount.
#We substitute the given values to determine amount after n years as follows:

Hence, the amount earned after n years is given by the expression
