(01.06 LC) Which number is not in scientific notation?
1 answer:
Answer:
Step-by-step explanation:
Hello!
Rules for scientific notation format:
- Has to be multiplied to a power of 10
- One factor has to be greater than 1 but less than 10
<u></u><u />
There is a multiplication to a power of 10, but the other factor is less than 1.
This is NOT in Scientific Notation.
All the other options have a multiplication operation to a power of 10, and all the other factors are above 1 and less than 10.

<u><em>Answer:</em></u>
x = 7
<u><em>Explanation:</em></u>
<u>We are given that:</u>
l = 7x - 7
m = 4x + 14
<u>We want to have:</u>
l = m
<u>Therefore, we will simply equate the two equations and solve for x as follows:</u>
7x - 7 = 4x + 14
7x - 7 - 4x = 4x + 14 - 4x
3x - 7 = 14
3x - 7 + 7 = 14 + 7
3x = 21
x =
x = 7

<h3>Answer: Choice C</h3>
=================================================
Explanation:
For choice C, the x values are out of order, so it might be tricky at first. I recommend sorting the x values from smallest to largest to get -2, -1, 0, 1, 2. Do the same for the y values as well. Make sure the correct y values stay with their x value pairs. You should get the list of y values to be 4, 2, 1, 1/2, 1/4
Check out the attached image below for the sorted table I'm referring to
We can see the list of y values is going down as x increases. This is a good sign we have decay. Further proof is that we multiply each term by 1/2 to get the next one
4 times 1/2 = 2
2 times 1/2 = 1
1 times 1/2 = 1/2
1/2 times 1/2 = 1/4
and so on. Effectively we can say the decay rate is 50%
