Suppose you first walk 12.0 m in a direction 20 owest of north and then 20.0 m in a direction 40.0osouth of west. how far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (if you represent the two legs of the walk as vector displacements a and b , then this problem asks you to find their sum r = a + b . the two displacements a and b add to give a total displacement r having magnitude r and direction in degrees.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
