Kira drained an aquarium. She took 20minutes. The graph shows the amount of water (in liters) in the aquarium versus time (in minutes). Find the domain and the range of the function shown.

The domain and the range of a function are the possible input and output values of the function.

The domain of the function is: [0,20]

The range of the function is: [0,200]

From the graph of the function (See attachment), we have the following observations

The x-coordinates of the graph is from 0 to 20

The y-coordinates is from 0 to 200

The x-coordinates represent the domain, while the y-coordinates represent the range.

Hence, the domain of the function is: [0,20] while the range of the function is: [0,200]

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
