I NEED HELP, need the answers to these question ASAP, please confirm if they're correct first, will give brainliest and points to correct answers. 1. James did an experiment. He started out with 640 bacteria cells. He found that the growth rate of the bacteria cells was 5.3%. Sketch the graph that represents the situation. Label the y-intercept and the point that represents the projected bacteria population 25 h from the time James started the experiment.(10 pts)

2.The function ()=150(1.3)represents the number of bikes sold at Peer’s Bike store in months. The graph represents the amount of bikes sold at Cycles R Us bike store in the same time period.(10pts)
During Week 0, how many more bikes were sold at Peer’s Bike shop than at Cycles r us? Explain.

3. Let ()=−3(2)and ()=−14.Complete the table to determine the solutions of ()=−3(2)= ()=−14.(10 pts)

The solution of ()=−3(2)= ()=−14is =

Part one: measurements 1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project. name relationship to student x height in inches y arm span in inches archie dad 72 72 ginelle mom 65 66 sarah sister 64 65 meleah sister 66 3/4 67 rachel sister 53 1/2 53 emily auntie 66 1/2 66 hannah myself 66 1/2 69 part two: representation of data with plots 1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph. part three: the line of best fit include your scatter plot and the answers to the following questions in your word processing document 1. 1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way. 2. write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. show all your work, including the points used to determine the slope and how the equation was determined. 3. what does the slope of the line represent within the context of your graph? what does the y-intercept represent? 5. use the line of best fit to you to describe the data correlation.

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
