Skip designs tracks for amusement park rides. For a new design, the track will be elliptical. If the ellipse is placed on a larg
e coordinate grid with its center at (0, 0), the equation (the drawing ^) models the path of the track. The units are given in yards. How long is the major axis of the track? Explain how you found the distance.
Given: center (0,0) the equation given should have been: x²/2500 + y²/8100 = 1
We need to identify the larger denominator. If it is under x, the ellipse is horizontal. If it is under y, the ellipse is vertical. In this case, 8100 is larger and it is under y so the ellipse is vertical.
(x-h)²/b² + (y-k)²/a² = 1
h and k are the center values which are both 0. a = length of the semi-major axis b = length of the semi-minor axis
The 8th grade does. All you do is divide each number by the amount of hours worked. So 6th grade 170/55 7th 112/4 and 8th 192/6 In the end its 6th= 3 dollars an hour 7th= 28 dolars an hour and 8th gets 32dollars an hour so they have the highest rate
By definition, the volume of a sphere is given by: V = (4/3) * (pi) * (r ^ 3) where, r: radius of the sphere. Substituting we have: V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3 answer the best estimate for the volume of air in the balloon in cubic inches is C. 113.1
