A large helium balloon is tethered to the ground by two taut lines. One line is 100 ft. long and makes an 80 degree angle with the ground. The second line makes a 40 degree angle with the ground. How long is the second line?

where is the diagram? shown below where? ?

step-by-step explanation:

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

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)
