9:19 Lesson 5 Mental Toughness Section 2 * 2 Stay focused. Relax. 5G |連続 -X 83% You might be surprised that even 押し続けると world-class athletes get nervous and - lose confidence. Roger Federer is one of the greatest tennis players of all time. He is the winner of 20 Grand Slam tournaments. You might think that he would have no problems keeping up his self-confidence. You would be wrong. Roger Federer is sometimes plagued with negative thoughts. He was playing a match which he had perfectly prepared for, yet somehow he was losing. When asked how he felt, he said, "No matter how positive you are, you just see negativity flying all around you." So what is his advice? Accept all the difficult thoughts and feelings and just stay focused on the game.

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.
