The first graph since it’s increasing rapidly while the second one is a parabola.
A. Is an exponential function
The first thing we need to do is use tan to find x. If the original angle of depression is 7 degrees, then the angle from the cliff to the bow of the boat is 90-7=83 degrees. Thus,<span>tan83 = <span>d / 150</span></span>or we can express it like this:<span>d =150 tan 83 ≈ 855.2</span><span>where d is the total distance from the boat to the cliff when the angle of depression is 7 degrees. Hope this helps a lot</span>
