Question Help A telescope contains both a parabolic mirror and a hyperbolic mirror. They share focus Upper F 1F1, which is 4545 feet above the vertex of the parabola. The hyperbola's second focus Upper F 2F2 is 77 ft above the parabola's vertex. The vertex of the hyperbolic mirror is 33 ft below Upper F 1F1. Find the equation of the hyperbola if the center is at the origin of a coordinate system and the foci are on the y-axis.

If forces acting on an object are unbalanced. true or false

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
