The following data table represents the total cost of a monthly cell phone bill as a function of the number of minutes that the phone is used each month.

Minutes :500 750 1,000 1,250 1,500
Total Monthly Cost: (in dollars) $62 $77 $92 $107 $122

The table shows that as more minutes are used each month, the total monthly cost will increase at the same rate.
Assuming that this is true, what is the total monthly cost for the cell phone if it is used for 2,500 minutes?

what is the graph

step-by-step explanation:

answer: x=3 and y=4

step-by-step explanation:

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)
