Step-by-step explanation:
Explanation:
Let M be the midpoint of AB. Then CM is the perpendicular bisector of AB. As such, center O is on CM, and OC is a radius (and CM). The tangent is perpendicular to that radius (and CM), so is parallel to AB, which is also perpendicular to CM.
If you need to go any further, you can show that triangles CMA and CMB are congruent, so (linear) angles CMA and CMB are congruent, hence both 90°.
The first thing you should do is plot each region with respect to the temperature and then observe the behavior of each region.
Region A: not observable trend
Region B: exponential trend
Region C: negative linear trend
Region D: positive linear trend

300. if you sold a third. then 2/3 would be left. you can then infer each is 300
