Suppose total revenue from sale of x items is provided by R(x)=29 ln(7x+1), while total cost to produce x items is C(x)=x/4. Determine approximate number of items which should be manufactured so that profit is maximum.
Each front tire on a hybrid is assumed to be filled to the pressure of 26 psi. Assume the actual air pressure in each tire is the random variable: X for the right tire and Y for left tire with the joint pdf. f(x,y) = k(x2 + y2) for 20 ? x ? 30 and
Civil engineers responsible for the design as well as maintenance of aircraft pavements traditionally use pavement-quality concrete. A study was conducted to access the suitability of concrete blocks as a surface for aircraft pavements.
