Calvin found cencus data for the population of Idaho from 1870 through 2000. He made a chart and scatter plot using this data.

the answer is d. (1.2, -4.7) on edgn

hope this !

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

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)
