Find f[g(x)] and g[f(x)].f(x) = 5x + 9; g(x) = 4x - 7
A. f[g(x)] = 20x + 26 g[f(x)] = 20x - 29 B. f[g(x)] = 20x + 29 g[f(x)] = 20x - 26 C. f[g(x)] = 20x - 26 g[f(x)] = 20x + 29 D. f[g(x)] = 20x - 29 g[f(x)] = 20x + 26
Find the x-value of all points where the function has relative extrema. Find the value(s) of any relative extrema.f(x) = 2 + 8x - x2
A. Relative maximum of 50 at 0. B. Relative minimum of 0 at 4. C. Relative maximum of 16 at - 4. D. Relative maximum of 18 at 4.
Use the two steps for solving a linear programming problem to solve the problem.An airline with two types of airplanes, P1 and P2, has contracted with a tour group to provide transportation for a minimum of 400 first class, 750 tourist class, and 1500 economy class passengers. For a certain trip, airplane P1 costs $10,000 to operate and can accommodate 20 first class, 50 tourist class, and 110 economy class passengers. Airplane P2 costs $8500 to operate and can accommodate 18 first class, 30 tourist class, and 44 economy class passengers. How many of each type of airplane should be used in order to minimize the operating cost?
A. 5 P1 planes and 17 P2 planes
B.
| 9 P1 planes and 13 P2 planes |
C. 11 P1 planes and 7 P2 planes
D. 7 P1 planes and 11 P2 planes
