                                             Question 11)

Step-by-step explanation:

Given the expression

Therefore,

                                            Question 12)

Step-by-step explanation:

Given the expression

Therefore,

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)
