Aboat a moving with speed 8kmh leaves point p whose position vector is r1=4i+3j heading directly towards point q whose position vector is r2=2i+5j. at the same time another boat b leaves point 0i+0j. if the velocity of boat b is vector vba=root2(-5i+3j), find a. the veloctiy of boat b b. the timetaken when the boats are close c. the shortest distance apart

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

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.

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