Find an equation fortne hyperbola described. Graph the equation. Center at (7', - 6); focus at (10, - 6); vertex at (9, - 6) An equation of the hyperbola is = 1. (Simplify your answer. Use integers or fractions for any numbers in the expression.) Find an equation for the hyperbola described. Graph the equation. Center at ( 3, - 1); focus at ( 3, - 9); vertex at ( - 3, -3) An equation of the hyperboia is =1. (Simplify your answer. Use integers or fractions for any numbers in the expression.) Under certain water conditions, the free chlorine (hypochlorous acid, HOCl) in a swimming pool decomposes according to the law of uninhibited decay. After shocking a pool, the pool boy, Geoff, tested the water and found the amount of free chlorine to be 2.6 parts per million (ppm). Twenty-four hours later, Geoff tested the water again and found the amount of free chlorine to be 2.3 ppm. What will be the reading after 2 days (that is, 48 hours)? When the chlorine level reaches 1.0 ppm, Geoff must shock the pool again. How long can Geoffgo before he must shook the pool again? After 2 days, or 48 hours, the amount of free chlorine in the pool will be ppm. (Do not round until the final answer. Then round to the nearest hundredth as needed.)
