1813_HW10_10.1to10.4_Fall21.pdf Page 2 of 2 3. (8 pts.) A hot brick was removed from an oven and begins to cool. Its temperature after t hours of cooling is given by C = H(t) = 22 + 200e-1.15t, where H is measured in degrees Celsius. (a) Find H-1 (C). (b) Find H 1(50) and interpret its meaning in the context of the problem. 4. (6 pts.) The following formulas arise in calculus: H(x) = F(x)G(x) h(x) = f(x) G(x) + F(x)g(x) F(xx) f ( ) G(x)-F(x)9(x) G ( x ) j (x) - (G (x))2 Find formulas for H (x), J(x), and j(x), given that: F(x) - 5x4 f ( x) - 20x3 h(x) = 10x5cos(x) + 20x3sin (x2) H(x) J(x) ; i (x) = 3 X 4. 10 0 MacBook Air
