Two factories blow their whistles at exactly the same time. If a man hears the two blasts exactly 4.2 seconds and 5.9 seconds after they are blown and the angle between his lines of sight to the two
factories is 40.8°, how far apart are the factories? Give your result to the nearest meter. (Use the fact
that sound travels at 344 m/sec.)
A) 2903 meters
B) 3263 meters C) 1329 meters D) 1997 meters

The base of a triangle exceeds the height by 9 inches. if the area is 180 square inches, find the length of the base and the height of the triangle.

What are the solutions to the following equation? |m| = 8.5 the value of m is equal to 8.5 and because each distance from zero is 8.5.

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
