the angle of elevation from the bottom of the worlds longest slide located in Peru Vermont is approximately 45 degrees. the slide covers a horizontal distance of 821 feet. what is the length of the slide?

a. is correct

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:

its less than 713.21 but greater than 5.2
