You will need the above information to help you interpret the graph. First off, keep in mind that although the exercise told you to write the sine equation based on the speculations it gave you, if you plan on writing your equation as a function of <em>cosine</em>, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of
in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the <em>sine</em> graph [photograph on the left], accourding to the <u>horisontal shift formula</u> above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY <em>REALLY</em> ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the <em>cosine</em> graph [photograph on the right] is shifted
to the left, which means that in order to match the <em>sine</em> graph [photograph on the left], we need to shift the graph FORWARD
which means the C-term will be positive, and by perfourming your calculations, you will arrive at
So, the cosine graph of the sine graph, accourding to the horisontal shift, is
Now, with all that being said, in this case, sinse you ONLY have the exercise to wourk with, take a look at the above information next to
It displays the formula on how to define each wavelength of the graph. You just need to remember that the B-term has
in it as well, meaning both of them strike each other out, leaving you with just a fraction. Now, the amplitude is obvious to figure out because it is the A-term, so this is self-explanatory. The <em>midline</em> is the centre of your graph, also known as the vertical shift, which in this case the centre is at
in which each crest is extended <em>one-half unit</em> beyond the midline, hence, your amplitude. So, no matter what the vertical shift is, that will ALWAYS be the equation of the midline, and if viewed from a graph, no matter how far it shifts vertically, the midline will ALWAYS follow.

Answer:
Step-by-step explanation:
given that a balloon is hovering 800 ft above a lake. The balloon is observed by the crew of a boat as they look upwards at an angle of 20 degrees. Twenty-five seconds later, the crew has to look at an angle of 65 degrees to see the balloon
The distance of the boat from the balloon measured horizontally in the I position = 800 tan 20
After 25 seconds distance of the boat from the balloon measured horizontally in the II position
= 800 tan 65
Distance moved by the boat in 25 seconds
= 
Speed of the boat per second =
53.702 feet per second is the speed of boat
The range of the data is 12
