Question 25 of 25 > Attempt 3 Find y' for the function y = x' cosh-' (2x). (Use symbolic notation and fractions where needed.) 5 cosh (2x)x# - 2x sinh (2x) cosh (2x) 2 IncorrectQuestion 21 of25 ) G Attempt 1 A bee ies around a circle traced on an equator of a ball with a radius of 9 cm at a constant distance of 5 cm from the ball. An ant travels along the same circle but on the ball. Use differentials to approximate how many more centimeters the bee travels than the ant in one round-trip journey. [Express numbers in exact form. Use symbolic notation and fractions where needed.) difference in distances: 4 Incorrect Question 20 of 25 Attempt 2 Find the linear approximation L(x) to f(x) = In (x + 8) at xo = 3. (Use symbolic notation and fractions where needed.) L(x) = 1 X + (- 17 + In(11)) IncorrectQuestion 19 of 25 > Find the linear approximation 1.0:} to f(x) = 95" at x9 = 9. (Use symbolic notation and fractions where needed.) Question 18 of 25 > Use Newton's Method with the first approximation c = 1.6 to find c3, the third approximation to the real zero of the function f(x) = x' - 7x + 4 in the interval (1, 8). (Use decimal notation. Give your answer to five decimal places.)
