A point, (m, 2), lies on the graph of the function y = log,(m + 3). The value of m is Answer: A formula involving atmospheric pressure and height above sea level is shown by d = 500log(P - 2) , 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
