Chapter 7, Problem 46E

Figure 7-43(a) shows a network of roads connecting cities A through G . The weights of the edges represent the cost (in millions of dollars) of putting underground fiber-optic lines along the roads, and the MST of the network is shown in red. Figure 7-43(b) shows the same network except that one additional road (connecting E and G ) has been added. Let x be the cost (in millions) of putting fiber-optic lines along this new road.

(connecting E and G) has been added. Let X be the cost (in millions) of putting fiber-optic lines along this new road.

Describe the MST of the network in Figure 7-43(a) in the case x > 59 . Explain your answer.

stacie is  a resident at a medical facility you work at. You are asked to chart the amount of solid food that she consumes.For the noon meal today, she ate 1/2 of a 3 ounce serving of meatloaf, 3/4 of her 3 ounce serving of mashed potatoes, and 1/3 of her 2 ounce serving of green beans. Show in decimal form how many ounces of solid food that Stacie consumed
Find the area of the shaded region. (a) 5- y 3 2- (1,4) (5,0) 1 3 4 5 6 (b) 3 y 2 Decide whether the problem can be solved using precalculus, or whether calculus is required. If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach. (Hint: Treat the shaded regi as…
