Complete each statement regarding an angle θ and its reference angle theta hat using radian measure. (Assume

0 ≤ θ < 2π.

Give your answers in terms of θ.)

(a) If θ is in QI, then theta hat =

(b) If θ is in QII, then theta hat =

(c) If θ is in QIII, then theta hat =

(d) If θ is in QIV, then =

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)

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
