500log(P - 2) A formula involving atmospheric pressure and height above sea level is shown by d = - 27 , where d is the distance above sea level, in kilometres, and P is the atmospheric pressure, in kilopascals (kPa). If a balloon floats to a height of 9 km above sea level, what is the atmospheric pressure, to the nearest hundredth of a kilopascal, at that height? Answer: If the graph of y = f(x) has a y-intercept of 6 and an x-intercept of 5, the graph of y =f-](x) has an x- intercept of Answer: A student graphed a function of the form g (0) = asin[b(8 -c)], where a > 0 and b 2 0, as shown below. She found three x -intercepts at IN 191 37 TT 3 3 and 3 . The value of b rounded to the nearest hundredth is
