The number of players, P, that have participated in a local basketball league has increased over the years and can be modeled by P = 7.51x^2 - 16.4x + 35 where x is the number of years. How many players were there in 7 years (so x = 7)

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

the answer is -1 1/5, also a
