The kilopascal is of 3000 m?
unit of measure for atmospheric pressure. Suppose the atmospheric air pressure at sea level is about 98 kilopascals. For every 1000-m increase in altitude, the pressure decreases about 11.3%. What is the approximate pressure at an altitude of 300 m?

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
