**Instantaneous rates of change. Exponential growth and Decay**

Find the instantaneous rate of change in Revenue R = −+20 4qq2 at q = 30 where q is the quantity of items sold. a) Using the table in Figure 2 as a guide, find the instantaneous rate of change numerically from the left side. Calculate the slope of secants lines through the following points where 1) q1=30 and q2= 29.5 3) q1=30 and q2= 29.99 2) q1=30 and q2= 29.9 4) q1=30 and q2= 29.999 . b... Find the instantaneous rate of change of annual total revenue with respect to the quantity of bearing presses sold when 50 bearing presses are sold annually. Solution Start by rewriting the definition of instantaneous rate of change for the function TR x() with a 50, 0 Instantaneous rate of (50 ) (50) lim change of ( ) at 50 h TR h TR TR x x h To calculate the limit, we need to find the

MTH 132 Chapter 1 - Functions and Limits MSU 4.2VIDEO - Tangent Lines, Instantaneous Rate of Change, and Applications Objective(s): Be able to visualize tangent lines....This would be a good activity to introduce the concept of the derivative shortly after students know how to find the instantaneous rate of change by using a limit. Once students are done the graphs on the charts, they can then move to extend their thinking with this Desmos activity where they visually estimate the slope of the tangent to eventually build the derivative (based on a original

### Sal approximates the instantaneous velocity of a motorcyclist.

- Example 2: Find the Instantaneous speed of the rock in Example 1 at the instant t =2. Now we have a problem. The speed at exactly 2 seconds implies that no time has elapsed (i.e. the change in time
- After looking at it graphically…..we used the equation we came up with to algebraically calculate the slope of the tangent line (the instantaneous rate of change). We then practice that calculation using other points the students were interested in knowing about.
- 15/08/2014 · Previously in class we began looking at how to find “instantaneous” speed (speed at an instant) rather than average speed. We saw that to do this we could use a tangent drawn at the point on the curve where we wanted to find the speed (or velocity).
