A biologist studied the populations of white-sided jackrabbits and black-tailed jackrabbits over a 5-year period. The biologist modeled the populations, in thousands, with the following polynomials where x is time, in years. White-sided jackrabbits: 9.7x2 – 0.8x + 2.3 Black-tailed jackrabbits: -1.1x2 + 7.7x + 5.4 What polynomial models the total number of white-sided and black-tailed jackrabbits? A. -8.6x2 + 6.9x - 7.7 B. 8.6x2 - 6.9x + 7.7 C. 8.6x2 + 6.9x + 7.7 D. 8.6x2 - 6.9x – 7.7

The map shows the location of the airport and a warehouse in a city. though not displayed on the map, there is also a factory 112 miles due north of the warehouse.a truck traveled from the warehouse to the airport and then to the factory. what is the total number of miles the truck traveled?

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
