1 answer:
The length of this pendulum that makes one full swing is 3.93 meters.
<h3>How to calculate the length of the pendulum?</h3>Mathematically, the time taken by this pendulum is given by this formula:
Making L the subject of the formula, we have:
Substitute all the values in the formula
Hence, the length of this pendulum that makes one full swing is 3.93 meters.

First, lets create a equation for our situation. Let 
be the months. We know four our problem that <span>Eliza started her savings account with $100, and each month she deposits $25 into her account. We can use that information to create a model as follows:
</span>
<span>
We want to find the average value of that function </span>from the 2nd month to the 10th month, so its average value in the interval [2,10]. Remember that the formula for finding the average of a function over an interval is:
. So lets replace the values in our formula to find the average of our function:
![\frac{25(10)+100-[25(2)+100]}{10-2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B25%2810%29%2B100-%5B25%282%29%2B100%5D%7D%7B10-2%7D%20)
We can conclude that <span>the average rate of change in Eliza's account from the 2nd month to the 10th month is $25.</span>
