If the output (y) is 71, what is the input number (x) for y = 8x + 77 A) 11.29
B) 9.75
c)8
D)9

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:

15.36 per mile

but forgot to round

i am pretty sure
