Find the exact area of the surface obtained by rotating the curve about the x-axis. y = sin (x/9) , 0 ≤ x ≤ 9

the answer to the question is a  

it has the same slope and the same y-intercept.

step-by-step explanation:

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)
