Find the period of the function.

y = 5 cos 1/2 x

Asailor is looking at a kite. if he is looking at the kite at an angle of elevation of 36and the distance from the boat to the point where the kite is directly overhead is 40 feet, how high is the kite?

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2 acellus answer

The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph. which is the residual value when x = –2? a)–2 b)–1 c)1 d)2
