4. The first graph plots data from a soap density measurement laboratory. The slope of the line is the density of the soap.
1. __________ Calculate the slope of the line.
2. ______________ Determine the y-intercept of the line.
3. y = _________ x + __________ Write the y = mx + b slope-intercept equation for the line.
4. [float] or [sink] The slope of the line is the density of soap. If the density of the soap is less than one gram/centimeter³ then the soap would float. If the density of the soap is greater than one gram/centimeter³ then the soap would sink. Based on the above, will this soap float or sink?
5. A student gathered the data seen in the table below. Plot the data on the graph.
1. __________ Calculate the slope of the line.
2. __________ Calculate the intercept of the line.
3. __________ cm. How far will the RipStik travel in 23 seconds?
4. __________ seconds. How long in seconds for the RipStik to travel 7500 centimeters?
6. __________ What is the slope of the line y = 2.0 + 0.15x?
7. __________ What is the y-intercept of the line y = 2.0 + 0.15x?
1. __________ _____ For a Brother XR-7700 sewing machine, calculate the power used based on the information in the images.
2. __________ _____ For a Brother XR-7700 sewing machine, calculate the resistance.
3. ________________ Power is now about forty cents per kiloWatt hour. How much would it cost to run the sewing machine for 24 hours?
1. __________ What is the atomic number of Zn?
2. __________ What is the atomic mass of Zn?
3. __________ How many protons does Zn have?
4. __________ How many neutrons does Zn have?
5. __________ How many electrons does Zn have?
8. [Note that in an atom the number of neutrons is equal to or greater than the number of protons. Thus the more numerous nucleons are the neutrons.]

16. The following graph is from laboratory fourteen. The dashed lines are the linear mathematical models for the flying ring and the flying in the 8:00 lab section. The solid line is the linear mathematical model for an orange "swerve" ball. The dotted line is the mathematical model for a non-flying object.

Based on the graph and analysis which objects are flying and which are not flying? Explain why.
