Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)

X+y=-4 x-y=2 use elimination with adding and subtraction

If the value of cos330°is√3/2 then find cos 165°.
