When I read the article, I found some cons and pros in social media. Media can make people know the news quickly, but it also can change someone’s opinion. People just create the fake story, then make others people support him. I think it affects me because nobody knows the trust of the story, it makes people attack others on the internet just because the “click bait” article. In this article, James Galen wrote to many political posts with the same view and he may not even be a real person. In a different example, at least eight accounts were created that posted and attacked the city councilor and her supporters. In conclusion, I believed the social media is bad at politics.
Misleading Statistics is a good way to mislead the people. The point of this method is to snipper the best or the worst part. Because of this, people can’t see the other part of the thing. I learned about critical thinking from misleading statistics. I made me understand argument: thinking cannot just think the external.
- How might your digital footprint affect your future opportunities?
When I post some essay on the website, somebody can find the digital footprint.
Don’t remain some bad word on the web because people may appeal you.
- Describe at least three strategies that you can use to keep your digital footprint appropriate and safe. Use Privacy Settings Look into Facebook’s proprietary privacy tips or get the works from Lifehacker.com with it’s “Always Up-to-Date Guide to Managing Your Facebook Privacy” Keep A List Of AccountsThen delete the ones you no longer use. That myspace page you signed up for? Don’t just forget about it–find it and delete it. Don’t Overshare
- What information did you learn that you would pass on to other students? How would you go about telling them? Some funny video or nice song
1. Represent repeated multiplication with exponent
For example: x*x*x*x=x^4
2. Describe how powers represent repeated multiplication
For example: y^4=y*y*y*y
3. Demonstrate difference between the exponent and the base by building model of a given power as 2^3 and 3^2
The power of 3^2 is 9 and the power of 2^3 is 8.From this, 3^2 isn’t same to 2^3
3^2 is 3*3
2^3 is 2*2*2
4. Demonstrate difference between two given powers in witch the exponent and the base are interchanged by using repeated multiplication, such as 2^3 and 3^2
The cube of 2 means 2*2*2, and the square of 3 means 3*3.
So cube means multiply for two times and square means multiply one time.
5. Evaluate power with integral based whole number exponent(excluding 0)
For example: a^m*a^n=a^(m+n)
6. Explain the role of parentheses in powers by evaluating a given set of powers such as ab^2 and (ab)^2
(ab)^2=a^2*b^2 From this they aren’t same
7. Explain the exponent laws for multiplying and dividing powers with the same base.
8. Explain the exponent laws for raising a product and quotient to an exponent.
9. Explain the law for powers with an exponent of zero.
All the number with the exponent of zero are one (excluding zero)
10. Use patterns to show that a power with an exponent of zero is equal to one.
All the number with the exponent of one are the number
11. Explain the law for powers with negative exponent law.
When exponent is odd and the base is negative, the power must negative.
Otherwise, when exponent is even and the base is negative, the power must positive.
12. Use patterns to explain the negative exponent law.
When exponent is negative result will be one over the base to power
13. I can apply the exponent laws to powers with both integer and variable bases
Improve this, I’ll give two examples
E.g.1: (-7)^3 ≠-7^3
∵All the number with the exponent of zero are one
14. I can identify the error in a simplification of an expression involving powers.
Using the exponent multiplying into the bracket
E.g. (3^4)^4 ≠3^8
15. Use the order of operations on expressions with powers.
Bracket has more priority than power
16. Determine the sum and difference of two powers.
17. Identify the error in applying the order of operations in an incorrect solution.
18. Use powers to solve problems (measurement problems)
A cube with side length of 10cm , what’s its volume?
Volume = side*side*side = side^3 = 10cm^3
Volume = 1000cm^3
19. Use powers to solve problems (growth problems)
A: 100*3^1=300 B: 100*3^2=900 C: 100*3^12=53144100 D: 100*3^n=3^n*100
20. Applying the order of operations on expressions with powers involving negative exponents and variable bases.
This week I learned many things,I knew many mechine safety in woodwork class.
In math class,I learned Adding and Subtracting integer.
