Because reptiles hibernate during the winter months, no reptiles are gathered during the months of January, February, November, and December. The number of lizards harvested during the remaining months can be modeled as h(m) = 15.3 sin(0.805m + 2.95) + 16.7 where m is the month of the year (i.e., m = 3 represents March), 3 sm s 10.+ (a) Calculate the amplitude and average value of the model. (Round your answer to one decimal place.) amplitude lizards average value | lizards (b) Calculate the highest and lowest monthly harvests. Write a sentence interpreting these numbers in context. (Round your answer to the nearest integer.) The most lizards harvested in one month is lizard(s) and the least harvested in one month (during harvest season) is lizard(s).

- Pls help ASAParrow_forwardCompare the phase shift and amplitude of y=-cos(x-180∘) and y=-2sin(x-90∘). Which of the following choices is the correct comparison? a The cosine function has a phase shift that is 12 that of the sine function and in the same direction; the amplitude of the cosine function is 2 times that of the sine function. b The cosine function has a phase shift that is 12 that of the sine function and in the opposite direction; the amplitude of the cosine function is 12 that of the sine function. c The cosine function has a phase shift that is 2 times larger than the phase shift of the sine function and in the same direction; the amplitude of the cosine function is 12 that of the sine function. d The cosine function has a phase shift that is 2 times larger than that of the sine function and in the opposite direction; the amplitude of the cosine function is 2 times that of the sine function.arrow_forwardNumber 83arrow_forward
