 In this video, we provide the solution to question number five for the practice final exam for math 1050 We got a story problem here. Terry is skiing down a steep hill Terry starts at an elevation of 4,000 feet and descends at 65 feet per second if the elevation of Terry is E of T after T seconds What's this function going to be? So notice here that if we're going down the hill Right this this slope going downwards really gives us a linear function, right? Terry started off at 4,000 feet. That's the initial value. Then we're descending at 65 feet per second. So that's a description of a rate. That's gonna be the slope here so if you think of our line being in the standard slope intercept form, right the intercept Was gonna turn out to be 4,000 right there the slope M would then be a negative 65 feet per second And so putting those together we see that the elevation of Terry is gonna look like negative 65 times T plus 4,000 the initial value and so this would then give us the feet that Terry is in with regard to elevation And so we then see that the correct answer would then be choice F I wrote it a little bit different, but it's the exact same function Terry's elevation would be 4,000 minus 65 T
