8. If3:8=c:56, the value of c will be

The scale for the second values is 56/8 = 7

C = 3 x 7 = 21

C= 21

a .4y4

hope this !

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:
