Of the 220 students who ate lunch, 145 ate salad and 200 ate pizza. how many ate both?

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

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:

i'll be glad to : )
