Suppose that the functions fand g are defined for all real numbers x as follows. f(x)=x-5
g(x) = 2x2
Write the expressions for (fg)(x) and (f-g)(x) and evaluate (f+g)(-1).

(fg) (x)= ?
(f-g) (x) = ?
(f+g) (-1) = ?

An objects motion is described by the equation d= 4sin (pi t) what will the height of the object be at 1.75 seconds?

100 points, hi, i’m not sure how to get the equation from the graph and table.

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.
