Part 2: How far can you travel?

Apparently, the length of your kayak affects the speed your kayak can travel. Based on the table below, choose a kayak length.

1) What kayak size are you picking?

2) Using the information you picked, if you travel at maximum speed upstream with a river current of 2 miles per hour, find how far it will take you to travel in 6 hou

A) First, draw a picture to depict the situation. Identify the variables and write an equation to solve for the distance.

B) Solve the equation and show your work./nPart 1

What's their speed?

You are going to calculate what speed the kayakers are paddling, if they stay at a constant rate the entire trip, while kayaking in Humboldt bay.

Page 4/4/nAlgebra 1 is all about equations and functions. First, you learned about Linear Functions and then Quadratic Functions. Next, you learned

about Rational Functions (indirect variation), then Exponential, and then Radical Functions. Before Algebra 1 comes to a close, it is good to

review these functions and compare them side by side.

Complete the table below.

The table has been created for you in a Worksheet. The worksheet is available as a Google Doc., Word, or PDF Worksheet. If you don't have

access to Google Docs. or Microsoft Word, download the PDF and create the worksheet in an application of your choice. If you use the Googl

doc. version, download your completed worksheet as a PDF. You MUST complete the worksheet and upload it as a PDF. All graphs need to b

inserted into the Worksheet, and every line item completed. Do NOT upload individual graphs; your work needs to be organized.

All images should be original. Graphed them using a digital calculator such as Desmos.com.

Resources: Desmos User Guide

Export a graph from Desmos by choosing 'Share' and then 'Export', or you can 'Print' them as a PDF. Alternatively, you can take a

screenshot of your graph. Insert the graph images into the worksheet table.

If it is not possible to graph

through these quadrants,

chose one or two quadrants and explain the choice.

At 1:00 pm, Ryan realizes his computer has been unplugged. He needs to work on the computer in his car and wants

it to be fully charged. The image on the right represents the time it took for the laptop to charge.

1. When can Ryan expect his laptop to be fully charged? Do a quick estimate and explain your reasoning.

2. He does a quick calculation at 1:17 and estimates the computer charges 1% a minute. He estimates it will be fully charged by 2:30. Was

he right?

3. Was his prediction over or under?

4. Create a table of values for the data points. You first need to convert the minutes to decimals. (Hint: to convert 1:04 pm to decimal, you

would take 1 + 4/60, which is 1.07).

5. Graph all the data points from your table. Use desmos.com to graph the points OR draw an original graph using graph paper.

6. Calculate the line of best fit for your graph. Use the regression tool on desmos.com to get the most accurate line of best fit. Write the line

of best fit in the form y=mx+b. Based on your line of best fit, when will the computer be fully charged?

7. Was your first estimate correct? Why do you think Ryan's first estimate was not accurate?
