Comet Trajectories Some comets, such as Halley’s comet, are a permanent part of the solar system, traveling in elliptical orbits around the sun. Other comets pas through the solar system only once, following a hyperbolic path with the sun at a focus. The figure below shows the path of such a comet. Find an equation for the path, assuming that the closest the comet comes to the sun is

(n - 1)!arrow_forwardAmy and Samiha have a hat that contains two playing cards, one ace and one king. They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king. Who is correct?arrow_forwardConsider the exponential function f(x) = 12x. Complete the sentences about the key features of the graph. The domain is all real numbers. The range is y> 0. The equation of the asymptote is y = 0 The y-intercept is 1arrow_forward
