Using C1 and C2 to represent the objective coefficients of X1 and X2, respectively, the slope of a line for the objective function can be represented by:a. C1/C2b. C2/C1c. -C1/C2d. -C2/C1e. None of these

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
