Explanation Given information: f ( x , y , z ) = x 2 y z , P = ( 1 , 5 , 9 ) Calculation: Since the gradient of function is denoted by ∇ f = 〈 ∂ f ∂ x , ∂ f ∂ y , ∂ f ∂ y 〉 The given equation f ( x , y , z ) = x 2 y z , Differentiating f with respect to x we get, ∂ f ∂ x = ∂ ∂ x x 2 y z ⇒ ∂ f ∂ x = y z ∂ ∂ x x 2 ⇒ ∂ f ∂ x = 2 x y z Differentiating f with respect to y we get, ∂ f ∂ y = ∂ ∂ y x 2 y z ⇒ ∂ f ∂ y = x 2 z ∂ ∂ y y = x 2 z Differentiating f with respect to z we get, ∂ f ∂ z = ∂ ∂ z x 2 y z ⇒ ∂ f ∂ z = x 2 y ∂ ∂ z z = x 2 y 1 2 z = x 2 y 2

A coffee shop currently sells 470 lattes a day at $3.50 each. They recently tried raising the by price by $0.25 a latte, and found that they sold 50 less lattes a day. a) Assume that the number of lattes they sell in a day, N, is linearly related to the sale price, 'p' (in dollars). Find an equation for N as a function of p. N(p) = b) Revenue (the amount of money the store brings in before costs) can be found by multiplying the cost per cup times the number of cups sold. Again using p as the sales price, use your equation from above to write an equation for the revenue, R as a function of p. Rip) = c) The store wants to maximize their revenue (make as much money as possible). Find the value of è that will maximize the revenue (round to the nearest cent). which will give a maximum revenue of S

Ohm's law states that the voltage drop Vacross an ideal resistor is linearly proportional to the current i flowing through the resistor as V= iR. Where R is the resistance. However, real resistors may not always obey Ohm's law. Suppose that you perform some very precise experiments to measure the voltage drop and the corresponding current for a resistor. The following results suggest a curvilinear relationship rather than the straight line represented by Ohm's law. i -1 - 0.5 - 0.25 0.25 0.5 1 V -637 -96.5 -20.25 20.5 96.5 637 Instead of the typical linear regression method for analyzing such experimental data, fit a curve to the data to quantify the relationship. Compute V for i = 0.1 using Polynomial Interpolation.
