Explanation for Question 11 From the Math (No Calc) Section on the 2017 May Sat
For question 11, they give us a scenario and then they give us a 2 bunch of, um, answer choices with different equations that are all in 3 slope intercept form. So our task is to read this paragraph 4 and determine what slope intercept form equation best fits 5 the scenario. Whenever I read a for your response, 6 our paragraphs, I like to circle the important parts. 7 So grab a pen and follow along. Paragraph reads the pressure extended 8 on an object underwater increases by one atmosphere for every 9 33 feet below the surface of the water at sea level. 10 The pressure is one atmosphere, 11 which equation gives the total pressure. Pete and atmospheres exerted 12 on the underwater object at the depth of F feet below sea level. 13 So we can think of this as a graph, 14 think of it as a graph, we plot our sea level 15 at the bottom. We plot our pressure on 16 the Y and they tell us that, 17 um, at sea level, 18 the pressure of the atmosphere, the pressure is one atmosphere. 19 So when we're at sea level zero at the origin, 20 in terms of the X, our atmosphere pressure is one that 21 makes her Y intercept one because it crosses the y-axis or it 22 starts in this case at one. 23 Then it says that it, 24 the entrepreneur water increases by one atmosphere, 25 every 33 feet. So if we moved 26 33 feet each time, so it's going to be 33, 66 99. 27 And so on each time that happens, 28 we increased by one atmosphere. 29 So we started at zero one. Our next point would be at 33 30 to our on...
