Tommy builds a model based on a drawing that uses the scale 1 cm : 20 cm. What would be the length of the model if the length of the drawing is 5 cm? A. 20 B. 21 C. 100 D.25

step-by-step explanation:

think the answer would beb

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)
