Sine of angle K= 1/2, square root of 3/3, 2 times the square root of 3, 2

B or 2nd choice

don't know if exact

Step-by-step explanation:

Sin(x) = 5√3/10 = 0.866025404

sin(x) = 0.866025404

x = sin^-1(0.866025404)

x = 60.00000002°

1/2 ≠ 60

√3/3 = 0.577350269

close enough

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)
