Rational Reasoning A change in t of 1 day (At = 1) The account value (in dollars) after t has changed by 1 day The change in the account value when 1 day has passed (a value of A f(t)) Correct! The length of the red arrow (vector) represents a change in time elapsed of 1 day (At = 1). This helps us focus our attention on the account values at the beginning and end of 1-day period (represented by the lengths of the blue segments). d. What does the length of the blue line segment on the right represent? Choose the best answer. OA change in t of 1 day (At = 1) The change in the account value when 1 day has passed (a value of Af(t)) The account value (in dollars) for some value of t The account value (in dollars) after t has changed by 1 day Correct! As you move the purple 'X' you are varying the value of t. The length of the blue segment on the left represents the account value (in dollars) at a given value of t and the length of the segment on the right represents the account value 1 day later. e. In your own words, explain how we can "see" the value of the multiplier 2 while interacting with this applet. Edit Insert Formats . B I U X X A A f. In your own words, explain how we can "see" the fact that the account value changes by 100% whenever t changes by 1. Edit * Insert * Formats * B I U X x AY AY
