The formula of the function would be:
y = 96000(1.07)^t
The graph is an exponential function with y-intercept of 9600. The curve goes upward indefinitely as the value of time increases.
Therefore, from the choices, the statements that apply to the graph are:
-The graph of the function begins at y = 96,000.
-The graph of the function shows the exponential growth.
By the angle difference formula for sines, we have:

By the angle sum formula for tangents, we have:

.
Rationalizing the denominator gives

as the final answer.
889/81= 10,97530864197531
