After each charging, a battery is able to hold only 95% of the charge from the previous charging. The battery was used for 15 hours on its first charge before it had to be recharged. What is the total number of hours the battery can be used over its lifetime?

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
