Answer:
Step-by-step explanation:
<em>Perimeter is the sum of side lengths</em>
<u>Let's find the sides first</u>
- AB = √(-2- 2)² + (-4+1)² = 5
- BC = (2 - (-1)) = 3
- CD = √(-1- 2)²+(5-2)² = √18 = 3√2 = 4.24
- DE = √(-4 -(-1))²+(2-5)²= √18 = 3√2 = 4.24
- AE = √(-4-(-2)²+(2-(-4))²=√40= 2√10 = 6.32
<u>Perimeter is</u>
- P = 5 + 3 + 4.24 + 4.24 + 6.32 = 22.8 ≈ 23 rounded to the nearest whole number
- 3/14 is your final answer.
Don’t worry! I am happy to help you! Standard form is just the number alone. In this case, here are the numbers written out for you.
1. 53
2. 9,400
3. 707,000
4. 0.0026
5. 0.08651
6. 0.0000067
The next part here is scientific notation. The first number has to be greater than 1, but less than ten, and the number you multiply by is powers of 10, sometime positively and sometimes negatively. You can search up the powers of 10 chart to find more. Here they are written in scientific notation.
7. 5.61 * 10^3
8. 1.4 * 10^1
9. 5.64 * 10^7
10. 7.52 * 10^-1
11. 6.4 * 10^-3
12. 5.81 * 10^-4
For this next part, you have to get these answers and express it in scientific notation. Here are these answers with the work.
13. 69,000,000 + 212,000 = 69,212,000.
Scientific notation: 6.9212 * 10^7
14. 43,000 + 521,000 = 564,000
Scientific notation: 5.64 * 10^5
Harrys answer would be 8-7, so 1 and Terry's answer would be 11. 1-11 is negative 10
