a dinosaur fossil is 92,170,000 years old. How can you express this age in scientific notation with the highest level of precision?
9.2x10^7
9.217x10^7****
9.22x10^7
9x10^7
Imma be honest>Im looking for the answers to the Lesson 9: Exponents and Exponential Functions Unit Test
Algebra 1 B Unit 2: Exponents and Exponential Functions
I cat find them if u found them paste a link to help out
U3 L9 Exponents and Exponential Functions Unit Test
1. - 1/10
2. 1
3. - y ^ 4
4. 5 ^ 11
5. 25
6. q ^ 18
7. 1/(1, 296q ^ 24)
8. - 11/2
9. x ^ 21
10. 16/(49y ^ 10)
11. Yes the number is written in scientific notation.
12. 1.4 * 10 ^ - 2, 1.4 * 10 ^ - 1, 1.5 * 10 ^ 3, 2 * 10
13. 2.4 * 10 ^ 3
14. 1.31 * 10 ^ 15
15. 9.191 * 10 ^ 7
16. 1.2*10^ -1 seconds

just putting letters as the answers doesn't guarantee a 100% 💀
correct
just keep looking them up im only looking them up to check my work but you do u.

Hope this helps🖤🤍
Make sure you place if the answers go to the honors test or the regular test. *shrug* Just sayin'
To express the age of the dinosaur fossil in scientific notation with the highest level of precision, we can follow these steps:
Step 1: Identify the non-zero digit in the number. In this case, it is 9.
Step 2: Count the number of decimal places from the non-zero digit to the end of the number. In this case, there are no decimal places since it is a whole number.
Step 3: Rewrite the number by moving the decimal point to the right or left to make it a number between 1 and 10. In this case, we move the decimal point one place to the left so that the number becomes 9.217.
Step 4: Multiply the rewritten number by a power of 10 that represents the count from step 2. In this case, we need to move the decimal point 7 places to the right to express the entire number. Thus, the power of 10 is 10^7.
Combining these steps, the age of the dinosaur fossil, 92,170,000 years old, can be expressed in scientific notation with the highest level of precision as 9.217 x 10^7.
