Question What is the general solution to the differential equation \( \cos y\left(2 \ln (x)-x^{3}\right) \frac{d y}{d x}=\frac{2}{x}-3 x^{2} ? \) \[ y=\arcsin \left(\ln \left|\frac{2}{x}-3 x^{2}\right|+C\right) \] \[ y=-\arcsin \left(\ln \left|\frac{2}{x}-3 x^{2}\right|\right)+C \] \[ y=\arcsin \left(\ln \left|2 \ln (x)-x^{3}\right|+C\right) \] \[ y=-\arcsin \left(\ln \left|2 \ln (x)-x^{3}\right|\right)+C \]

Identify the planes that are perpendicular. O x-12y = 6,-11x – 232 = 2 14 O x+12y = 6, -11x - y - 23z = 2 O x + 12y-z = 6.-11x – 1 – 232 = 2 O x + 12y = 6.-11.x - 237 = 2 O 12x - y - z= 6.-11x + y - 23z = 2

P3.5 The sales revenue, food cost of sales, and guests served for a small fast- food carryout division of a restaurant for the past six months are given below. Sales Month Cost of Revenue Guests Served Sales, Food 1 2. 4 $258,200 274,800 285,600 289,400 298,300 304,600 $ 96,200 104,300 110,500 113,100 118,900 123,700 10,200 10,400 10,300 10,100 10,400 10,500 6 For each of the six months calculate average check and average costs of sales food. Using these averages, calculate an index number. Set the in- dex for month 1 at 100 and complete index numbers for the remaining five months. With the index numbers identified, convert sales revenue and cost of sales food from historic to current dollars.

A cylindrical rock sample has a length of 6 cm, a diameter of 4 cm, and a dry weight of 166.4 g. When fully saturated with an oil of density 0.85 g/cm3, the weight of this sample is 176.9 g. Assuming constant temperature, find: i) The porosity of the sample ii) The pore compressibility of the sample, given that 0.2 cm of oil leaves the sample when a pressure of 3200 psig is applied on it iii) The amount of oil that can be extracted from the sample when a pressure of 2000 psig is applied on it
