A25 stamp is increased to 30. what percent of the original price does this increase represent?

       =20% increase

Step-by-step explanation:

To find the percent increase,

increase = (new - original)/ original * 100%

Then new price is 30 and the original price is 25

increase = (30-25)/25 * 100%

               =5/25 * 100%

                =.2 *100%

                 =20% increase

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)
