Required information Concrete expands both horizontally and vertically over time. An article reports measurements of horizontal and vertical expansion (in units of parts per hundred thousand) made at several locations on a bridge in Quebec City in Canada. The results are presented in the following table. Horizontal 43 Vertical 55 5 18 24 32 10 21 80 58 68 57 69 63 For what horizontal expansion would you predict a vertical expansion of 65 parts per hundred thousand? The required horizontal expansion is 26.55 parts per hundred thousand.

Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. It is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day. island 4 km 16 km W L D nest @ A bird with these tendencies is released from an island that is 4 km from the nearest point B on a straight shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Points B and D are 16 km apart. Assume that the bird instinctively chooses a path that will minimize its energy expenditure. (Round your answers to two decimal places.) (a) In general, if it takes 1.2 times as much energy to fly over water as land, to what point C should the bird fly in order to minimize the total energy expended in returning to its nesting area? km from B (b) Let W and L denote the energy (in joules) per kilometer flown over water and land, respectively.…
