Satellites in near-earth orbit experience a very slight drag due to the extremely thin upper atmosphere. these satellites slowly but surely spiral inward, where they finally burn up as they reach the thicker lower levels of the atmosphere. the radius decreases so slowly that you can consider the satellite to have a circular orbit at all times. as a satellite spirals inward, does it speed up, slow down, or maintain the same speed?

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.)
