Lego has unveiled its first bricks made from recycled plastic bottles and ( 11 ) that it hopes to include the pieces in sets within two years. The prototype 4x2 bricks have been made from PET plastic from ( 12 ) bottles with additives to give them the strength of standard Lego parts, and are the result of three years of ( 13 ) with 250 variations of materials. It has already ( 14 ) plans to remove single-use plastic from boxes, and since 2018 has been ( 15 ) parts from bio-polyethylene (bio-PE), made from sustainably sourced sugarcane. These parts are bendy pieces, such as trees, leaves and accessories for figurines. Tim Brooks, vice-president for environmental ( 16 ) at Lego Group, said the biggest challenge was "rethinking and innovating new materials that are as ( 17 ), strong and high (18) as our existing bricks and fit with Lego elements made over the past 60 years". He added: "We're committed to playing our part in building a sustainable future for generations of children. We want our products to have a positive ( 19 ) on the planet, not just with the play they inspire, but also with the materials we use.

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.
