The current of the Naboo River has speed 2 mph. It takes Senator Amidala's boat a total of 3 hours to travel 8 miles upstream and 8 miles back. Set up an equation that would find the speed of the boat in still water.

What is the value of the expression below? (81^2)^1/8

What function has a range {yly< 5}? question on picture above^

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
