3. A point, (m, 4), lies on the graph of the function y = log: (m + 2). The value of m is Hint: Express the given function as an exponential equation, replacing y with the y-value in the given point, and then solve for m. Numerical Response 4. A formula involving atmospheric pressure and height above sea level is shown by d = 500 log (P - 2) 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 8 km above sea level, what is the atmospheric pressure, to the nearest hundredth of a kilopascal, at that height? Hint: Graph d = 8 and d = 500 log (P - 2) 27 , and determine the x-coordinate of the intersection point
