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.

写真でマーカーを引いた"that way"はどういう意味合いなのでしょうか？ <指摘している1文の和訳> しかし、創造的な人々は生まれつきそのような脳を持っているのか、それとも学習して創造的になっていくのかは未だに明らかではない。

now that's a 1 We all take pride and pleasure in being called smart or intelligent. But when someone says to us "How creative you are!" compliment! But what does this really mean? What exactly is creativity? One definition says that creative people have the ability to: generate brand-new ideas or concepts, and make (7) unprecedented connections between ideas and concepts that already exist. Which brings up another question: Where does creativity stem from? Neuroscience is actively investigating how creativity works in the brain. So far it has found that in highly creative people, the various regions of the brain work especially well together. There is a high level of cooperation and communication among those regions. (1) This makes for (イ) divergent thought, a key aspect of creativity. But whether creative people's brains are born that way, or whether they learn to be creative is still not clear. It's the old question of "nature" versus "nurture." -
