Question 1183417:
1. The arch of a small bridge across a stream is parabolic. If at water level, the span of the arch is 80ft and the maximum height above water level is 20ft, what is the equation that represents the arch? Choose the most convenient point for the origin of the coordinate system.
2. The temperature in a certain region is 270C, and at an altitude of 2500 m above the region is 120C. If the equation relating the temperature T and the altitude h is linear, find the equation.
Your question #2 is faulty. 270C temperature in a region but no indication of altitude. Maybe this is relative to the next two-dimensional point?
At the region taken as 0 meter above it, so the point is (0, 270) and your next point would be (2500, 120). So if this is linear relation ship then , and then m for slope, ; do from this what you need.
