What is the value of sin a for this triangle?

The sine of the angle is the ratio of the opposite side to the hypotenuse. The hypotenuse of this triangle can be computed from the Pythagorean theorem:
.. AB = √(AC^2 +BC^2) = √(9 +4) = √13 . . . . cm
Then the ratio of opposite side BC to the hypotenuse AB is
.. sin(A) = BC/AB = 2/√13

Corresponds to the 3rd selection.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
