Resistors in parallel Two resistors wired in parallel in an electrical circuit give an effective resistance of
a. Graph the resistance function using the window [0, 10] × [0, 10] × [0, 5].
b. Estimate the maximum value of R, for 0 < x ≤ 10 and 0 < y ≤ 10.

- the second is the Problem 1 solution.arrow_forwardc) Sketch the grap 109. Hearing Impairments. The following function approximates the number N, in millions, of hearing-impaired Americans as a function of age x: N(x) = -0.00006x³ + 0.006x2 -0.1x+1.9. a) Find the relative maximum and minimum of this function. b) Find the point of inflection of this function. Sketch the graph of N(x) for 0 ≤ x ≤ 80.arrow_forwardThe purpose of this problem is to solve the following PDE using a numerical simulation. { af (t, x) + (1 − x)= - Ət af 10²ƒ + მე 2 მე2 = 0 f(ln(2), x) = ex (a) The equation above corresponds to a Feynman-Kac formula. Identify the stochastic process (X)20 and the expectation that would correspond to f(t, x) explicitly. (b) Use a numerical simulation of (X+) above to approximate the values of f(0, x) at 20 discrete points for x, uniformly spaced in the interval [0,2]. Submit a graph of your solution. (c) How would you proceed to estimate the function f(0.1, x). (Briefly explain your method, you do not need to do it.) Extra question: You can explicitly determine the function in (b) (either as a conditional expectation or by solving the PDE). Compare the theoretical answer to your solution.arrow_forward
