B and D are the only true statements.
<span>
A </span>function<span> is a relation for which each value from the set of the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair. Alternatively, you can think of this as for each x, there is one and only one y. Clearly that is not the case here, but it is the equation of the vertical line </span>x = 3.

If cos theta = 3/5 and theta is in quadrant 4, tan 2 theta =
Neko [114]

Answer:

16/9.

Step-by-step explanation:

I am assuming you mean tan^2 theta.

The adjacent side of the triangle drawn in Q 4 = 3 (as cos theta = 3/5.

The opposite side of the triangle drawn in Q 4 = sqrt(5^2-3^2) = 4.

The tangent is negative in Q 4

So tan theta = -4/3.

tan^2 theta = 16/9.
