Rachel is a stunt driver, and she's escaping from a building that is about to explode! DDD represents Rachel's remaining distance (in meters) as a function of time ttt (in seconds). D=-38t+220D=−38t+220 (I know that the answer is 38 meters per second, but why isint it negative 38 per second, since a negative 38 is in the origanal problem?) thanks

M. xyz =radians. covert this radian measure to its equivalent measure in degrees.

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a, b and c integers and a> 1

Answer this two poles, ab and ed, are fixed to the ground with the of ropes ac and ec, as shown: two right triangles abc and edc have a common vertex c. angle abc and edc are right angles. ab is labeled 13 feet, ac is labeled 15 feet, ec is labeled 10 feet, and ed is labeled 4 feet. what is the approximate distance, in feet, between the two poles? 11.14 feet16.65 feet14.35 feet15.59 feet
