2. The economy of a small country is based on four sectors: agriculture, manufacturing, transportation and tourism. The internal demand for these sectors is described below. To produce $1 of output: • Agriculture requires $ 0.07 of agriculture, $0.18 of manufacturing, $0.15 of transportation and $0.04 of tourism • Manufacturing requires $0.11 of agriculture, $0.21 of manufacturing, $0.14 of transportation and $0.07 of tourism • Transportation requires $0.10 of agriculture, $0.23 of manufacturing, $0.12 of transportation and $0.09 of tourism • Tourism requires $0.22 of agriculture, $0.25 of manufacturing, $0.15 of transportation and $0.02 of tourism Find the output from each sector that is necessary to meet consumer demands of $23 million for agriculture and $29 million for manufacturing, $18 million of transportation and $8 million of tourism.

Use this data and develop a model of a truck's annual maintenance expenses based on its weekly usage in hours. If the truck's weekly usage is 25.3 hours, we should expect its annual maintenance expense to be:  (Keep one decimal place) Weekly Usage (hours) Annual Maintenance Expense 13 17.0 10 22.0 20 30.0 28 37.0 32 47.0 17 30.5 24 32.5 31 39.0 40 51.5 38 40.0

The line in the graph shows a relationship between two variables, x and y. What is the slope of the curve? ... The slope of the curve is >>> If the slope is negative, use a minus sign. If the slope is positive, do not use a plus sign. 8 7 5- 4- 3- 2- 1- 0- y 0 1 2 3 4

Given the functional relationship: y = 14x5/x2  find the value of y when x = 1.5
