The height in feet of an arrow is modeled by the equation h(t)=(1+2t)(18-8t) where t is seconds after the arrow is shot. When does the arrow hit the ground

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

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)
