1. determine if the number is written in scientific notation. if not, explain 32x10^4
a. no; it is not written as a power of 10
b. no; the first factor is not a number between 1 and 10
c. yes; the number is written in scientific notation

2. determine if the number is written in scientific notation. if not, explain 2.01x 10^-5
a. no; it is not written as a power of 10
b. no; the first factor is not a number between 1 and 10
c. yes; the number is written in scientific notation

1) 32*10^4 is not written in scientific notation because the first factor is not a number betweem 1 and 10.

3.4 * 10^5 is the same number written in scientific notation.

2) 2.01x10^-5 is written in scientific notation.

1)

option b is correct.

2)

Option c is correct.

Step-by-step explanation:

We know that any number is in scientific notation if it could be represented as:

So the number is written in two parts:

Just the digits (with the decimal point placed after the first digit), followed by × 10 to a power that puts the decimal point where it should be .

1)

32×10^4 is not expressed in scientific notation as the decimal point is not placed after the first digit.

Hence option b is correct.

The number in scientific notation is:

(3.2×10^5)

2)

2.01×10^-5.

Yes, the given expression is in scientific notation as it satisfies the above two rules of number in scientific notation.

Hence, option c is correct.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Is 8.50 an answer or no? ?
