Step-by-step explanation:
Circle is centred at (0, -2)
-> h = 0 & k = - 2
radius of the circle (r) = y-coordinate of the center = - 2
Equation of circle in standard form is given as:
Plugging the values of h, k and r in the above equation, we find:
This is the required equation of circle.
The rate of change of Pete's height from 3 to 5 years can be determined as,
Thus, the required rate of change from 3 to 5 years is 4 in/year.
