Answer:
y = 0.20x(-38,000) + 38,000
Step-by-step explanation:
y: represents how much the price is now.
x: Represents the number of years passed.
y = 0.20x(-38,000) + 38,000
For example if it's 1 year
y = 0.20(1) (-38,000) + 38,000
y = 0.20(-38,000) + 38,000
y = -7600 + 38,000
y = 30,400

Which table represents a linear function?
Table one represents a linear function for the given data.
What is a linear function?A linear function is a mathematical function that can be written in the form:
y = mx + b
where "m" and "b" are constants, and "x" and "y" are variables.
In this form, "m" represents the slope of the line, and "b" represents the y-intercept, the point where the line crosses the y-axis. The slope of the line is the rate of change of the function, representing how much the value of "y" changes for every unit change in "x".
The given table is,
x y
1 5
2 10
3 15
4 20
5 25
The slope of the given data is,
m = ( 10 - 5 ) / ( 2 - 1 ) = 5
m = ( 15 - 10 ) / ( 3 - 2 ) = 5
m = ( 20 - 15 ) / ( 4 - 3 ) = 5
Here the slope is constant, so the function is linear.

This hanger is in balance. There are two labeled weights of 4 grams and 12 grams. The three circles each have the same weight. What is the weight of each circle, in grams?
Answer:
8/3 gram
Step-by-step explanation:
Since the hanger is said to be in balance, then the weight on the right balances the weight on the left ;
Right hand side = Left hand side
12 = 4 + x + x + x
12 = 4 + 3x
12 - 4 = 3x
8 = 3x
8/3 = 3x / 3
x = 8/3 gram

Introduction
Scientists have established a timeline of events after the Big Bang, based on astronomical observations and our understanding of the physical laws of the universe, such as gravity and the speed of light. In this lab activity, you will gather evidence to support the Big Bang theory.
Problem:
How can models demonstrate theories of our expanding universe?
Hypothesis:
Review the virtual lab demonstration in the lesson and stop the video when prompted to formulate a hypothesis. Hypothesize (or predict) what will happen to the distances between the labeled circles when you blow up the balloon ¼ full, ½ full, and ¾ full. Remember to include independent and dependent variables in your hypothesis.
The carbon dioxide represents how galaxies will spread out.
Materials:
Watch the virtual lab demonstration video within the lesson. No additional materials are needed.
Variables:
For this investigation:
List the independent variable(s):
List the dependent variable(s):
List the controlled variable(s):
Procedures:
1. Watch the virtual lab demonstration video within the lesson and record your observations in Table 1.
2. Using your expanding universe data from Table 1, construct a line graph using the volume of the below on the X axis and the distance between points on the Y axis. Be sure to include units and add titles to the graphs. Refer to the graph example and graphing tutorial in the lesson if needed.
3. Complete the Questions and Conclusion section of the lab report.
Data and Observations:

Construct a line graph using the expanding the universe data from table 1. The volume will be plotted on the x-axis. The distance between the points will be plotted on the y-axis. Be sure to include units and add titles to the graph. Refer to the graph example and graphing tutorial in the lesson if needed.
Place your graph here.
Questions and Conclusion
1. How does the density and distribution of your “stars” change as the balloon expands?
2. How does your expanding balloon model represent an expanding universe?
3. What are some shortcomings of using this model as a replica of universe expansion?
4. How does the model you created help to show that the Steady State theory is inaccurate?
5. Suggest a way that a scientist could create an even more accurate model of universe expansion.
6. What will happen to the gravitational force between stars as the universe continues to expand?
In conclusion, how did your prediction of distances between points compare to your experimental results? All I truly need is the variables question 3 and 5 and I’m good :) thank you <3 this is for science but I didn’t know which one to pick so I picked a random one lol

If there are 520 grams of radioactive material with a half life of 12 hours how much of the radioactive material will be left after 72 hours? Is the radioactive decay modeled by a linear function or an exponential function
Answer:
16.25 grams are left
exponential
Step-by-step explanation:
Half the material will decay every 12-hour period (the other half will remain).
Initial amount (at time t = 0): 520 grams
Time t = 12: 260 grams are left
Time t = 24: 130 grams are left
Time t = 36: 65 grams are left
Time t = 48: 32.5 grams are left
Time t = 72: 16.25 grams are left
Radioactive decay is modeled by an exponential function. The function can't be linear because for them, equal time steps would produce equal reductions in the amount of material.
