The distance in miles thax the lookout of a submarine
can see is approximately
d=1.22vh, where h is the
height of the lookout above
the water. How far would a
submarine periscope have
to be above water to locate
a ship 6 miles away?

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

i those same problems in math and dont know how to do them
