Aiden borrows a book from a public library. He reads a few pages on day one. On day two, he reads twice the number of pages than he read on day one. On the third day, he reads 6 pages less than what he reads on the first day. If he reads the entire book which contains 458 pages in 3 days, how many pages did he read on day three?

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. Maximum Speed Table Waterline Length Miles Per (Feet) Knots Hour 9 4.0 4.6 10 4.2 4.9 11 4.4 5.1 12 4.6 5.3 13 4.8 5.6 14 5.0 5.8 15 5.2 6.0 16 5.4 6.2 17 5.5 6.4 18 5.7 6.5 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?

Provide supporting work and detail - + 100% <Cobylink RH 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. Parent Function: Notation Parent Function: Graph Translation: Graph a function that extends only through quadrants 1, 2, and 4.

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?
