Explanation for Question 12 From the Math (No Calc) Section on the 2020 October Sat
So question 12 gives us a function AFT and tells us that T is 2 ours. And so this is important for our question. 3 We need to know that T is in the units of ours. 4 Then if we read on the question that's asking us is what would the 5 function look like if we were talking about M minutes rather than T hours. 6 So we can notice the only thing that's changing from answer to answer is 7 what's happening in the exponent. So we need to figure out how to convert 8 our hours into minutes, or rather actually how to take 9 our minutes and convert it into hours so that this what's happening. 10 Exponent is the same thing as T. And so if we think about what 11 we would do, if we try to convert something in minutes to hours, 12 let's say for example, that we had 20 minutes, 13 it doesn't tell us this in the question, but we can pretend and kind 14 of come up with our own numbers. If we had 20 minutes and wanted 15 to convert it to hours, we would take one hour and we would divide 16 by 60, right? Cause then our minutes will cancel and we'll be left with 17 hours. So what we're doing is we're taking our number of minutes and 18 we're dividing by 60 is we can see here. 19 And so the answer choice that shows us that is a.
