What is the image of (
−
1
,
9
)
(−1,9) after a dilation by a scale factor of
2
2 centered at the origin?

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:

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
