Answer:990

Step-by-step explanation:

Since the president has 11 chances, the vice president has 10 chances, and the treasures has 9 chances, then there are 11 x 10 x 9 = 990 way of choosing them.

Or,

11P3 = 11!/(11 - 3)! = 11!/8! = (11 x 10 x 9 x 8!)/8! = 11 x 10 x 9 = 990

The Graph describes the water level of creek after a rainstorm which best describes the domain in context?

belka [17]

The domain of a function are its possible input values

The domain of the function is (b) all real numbers greater than or equal to 0.

From the graph, we have the following observations

t represents time (it is plotted on the x-axis)
t starts at 0
t has no end

The above observations imply that; the domain starts from 0

Hence, the domain of the function is the set of all real numbers greater than or equal to 0.
