赤く丸をしたbの問題で解答の方に二階微分した後の式がなぜ(-1/4)(-1/4)(H-27)になるのか分かりません。教えてください🙇‍♀️

QA At time t = 0, a boiled potato is taken from a pot on a stove and left to cool in a kitchen. The internal temperature of the potato is 91 degrees Celsius (°C) at time t = 0, and the internal temperature of the potato is greater than 27°C for all times t > 0. The internal temperature of the potato at time t minutes can be modeled by the function H that satisfies the differential equation dH (H- (H-27), where H(t) is dt measured in degrees Celsius and H(0) = 91. (a) Write an equation for the line tangent to the graph of Hat t = 0. Use this equation to approximate the internal temperature of the potato at time t = 3. (b) Use 2017 APⓇ CALCULUS AB FREE-RESPONSE QUESTIONS (a) dH d²H dt² to determine whether your answer in part (a) is an underestimate or an overestimate of the internal temperature of the potato at time t = 3. (c) For t < 10, an alternate model for the internal temperature of the potato at time 7 minutes is the function -= − (G - 27)²/3, where G(t) is measured in degrees Celsius dG G that satisfies the differential equation dt and G(0) = 91. Find an expression for G(t). Based on this model, what is the internal temperature of the potato at time t = 3 ? 564 at (21-27) - == 2-16 To = - = (H(3)-27) 4 -64 = HB)-27 -37 = H (3) (b) _d²fi © 2017 The College Board.

(2) In English-speaking cultures, children are often told to say "please" when asking for something. By so doing, they are more likely to be given イ permission than they do not. If they don't, their parents give them a hint, by asking them " What's the magic word?" Trying to forecast weather is incredibly complicated. Some scientists P believe that no matter how advanced science is, weather is impossible to イ predict it accurately, because there are too many random elements involved. (3) Inuits are a related group found in Alaska, and also in Canada and Greenland. They are thought to have spread into North America from Siberia many thousands years ago. In both the US and Britain these people are ウ often called Eskimos but the name Inuit is now preferred and is becoming more widely used. 5) The Cold War is a term for the political conflict between the capitalis countries of the West and the Communist countries of the East that begar 7 after World War II.
