What is the phase shift and period for the function y = 3cos6(θ − 30°) + 4?

phase shift = right 30°, period = 60°

phase shift = right 30°, period = −60°

phase shift = left 30°, period = 60°

phase shift = left 40°, period = 30°

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
