∘
∠a=30
∘
angle, a, equals, 30, degrees and
a

ab=12
3

a, b, equals, 12, square root of, 3, end square root.

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:

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

the answer would be c

the square root of 16 is 4.

4*4 = 16
