A computer cost $800. It loses 1/4 of its value every year after it is purchased. complete the table to show the value of the computer at the listed times.

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)

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
