Select the correct answer below: ○ 1 ○ 4 -4 The limit does not exist. -2x² - 2x x 1arrow_forward(4) (8 points) (a) (2 points) Write down a normal vector n for the plane P given by the equation x+2y+z+4=0. (b) (4 points) Find two vectors v, w in the plane P that are not parallel. (c) (2 points) Using your answers to part (b), write down a parametrization r: R² — R3 of the plane P.arrow_forward(2) (8 points) Determine normal vectors for the planes given by the equations x-y+2z = 3 and 2x + z = 3. Then determine a parametrization of the intersection line of the two planes.arrow_forward

- Find the limit. (If the limit is infinite, enter 'oo' or '-o', as appropriate. If the limit does not otherwise exist, enter DNE.) lim X→ ∞ (✓ 81x2 - 81x + x 9x)arrow_forward2) Compute the following anti-derivative. √1x4 dxarrow_forwardQuestion 3 (5pt): A chemical reaction. In an elementary chemical reaction, single molecules of two reactants A and B form a molecule of the product C : ABC. The law of mass action states that the rate of reaction is proportional to the product of the concentrations of A and B: d[C] dt = k[A][B] (where k is a constant positive number). Thus, if the initial concentrations are [A] = = a moles/L and [B] = b moles/L we write x = [C], then we have (E): dx dt = k(ax)(b-x) 1 (a) Write the differential equation (E) with separate variables, i.e. of the form f(x)dx = g(t)dt.

(d) Solve the differentiel equation (E), i.e. find x as a function of t. Use the fact that the initial concentration of C is 0. (e) Now assume that a = b. Find x(t) assuming that a = b. How does this expression for x(t) simplify if it is known that [C] =…arrow_forward
