Use demoivre’s theorem to write the complex number in trigonometric form. (cos(3pi/t)+isin (3pi/5))^3 your choices are: 3(cos(9pi/5)+isin (9pi/5)) (cos(3pi/15)+isin (3pi/15)) 3(cos(3pi/15)+isin (3pi/15)) (cos(9pi/5)+isin (9pi/5))

Acircular garden with radius of 8 feet is surrounded by a circular path with a width of 3 feet. what is the approximate area of the path alone? use 3.14 for π

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable
