A remote control helicopter travels 24.6 km in 30 minster find the speed of the helicopter in m/s​

Triangle xyz has vertices x(1,3), y(0,0)

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
