Answer:

I think that the other answer is WRONG

tan(12) = \frac{x}{40}

x = tan(12)*40 = 8.5

Step-by-step explanation:

\frac{sin\left(78\right)}{40}=\frac{sin\left(12\right)}{x} = 8.5

The graph of a function is shown below. Which ordered pair best represents the location of the y intercept
Wittaler [7]
When a question is asking you for the y-intercept based on a graph, all you have to do is look to see at what point does the function cross/intersect the y-axis. The x-value will always be zero in a y-intercept. By looking at the graph you see that the function crosses the y-axis at the point (0, -1), which is your answer.

Answer: (0, -1)
