The perimeter of a rectangle of lenght 6cm and width 4cm can be given as?

Step-by-step explanation:

perimeter of a rectangle = 2 * ( length + width)

= 2*(6+4)

= 2 * 10 = 20 cm

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)
