Answer:
Center is at (0,0)
Step-by-step explanation:
An equation of ellipse in standard form is:
Where center is at point (h,k)
From the equation of . First, we add 45 both sides:
Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:
Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
Answer:
Step-by-step explanation:
So the initial value of the business computer is $20,000. It depreciates by 15% per year. This is exponential decay. The standard function for exponential decay is:
Where <em>P </em>is the initial value, <em>r</em> is the rate of decay, and <em>t</em> is the time in years.
Since the computer decreases by 15% per year, this means that each year, the computer will be 1-15% or 85% than its previous value.
Therefore, the equation that models the value of the computer is:
