Mara and taylor need to rent a car for 6 days. if the cost of the car is $105 for each day, which of the following expressions could they use to figure out the total cost? a. 6(100) – 6(5) b. 6(110) + 6(5) c. 6(100) + 6(5)

I am pretty sure it is C. 6(100) + 6(5)

The answer is c. 6(100) + 6(5)

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
