Four is a zero of the equationx3+3x2−18x−40=0. Which factored form is equivalent to the equation?

(x+2)(x−4√)(x+4√)=0

(x−4)(x+4)(x+5)=0

(x−4)(x+2)(x+5)=0

(x+4)(x+2)(x+5)=0

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)
