Given the displacement vectors A = (8.00 î − 9.00 ĵ + 5.00 ) m and B = (7.00 î + 5.00 ĵ − 3.00 ) m,
find the magnitudes of the following vectors and express each in terms of its rectangular components.
A) C = + || = m = ( î + ĵ + ) m
B) D = 2 - || = m = ( î + ĵ + ) m

Ms. hidalgo opens the door to her classroom. her classroom is 60 degrees and the air outside is 80. predict what will happen using your knowledge of how heat flows.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
