16,-2 would be the answer I believe
Answer:
Step-by-step explanation:
To solve this problem, all you have to do is solve by order of operations.
<u>PEMDAS stands for:</u>
- Parenthesis
- Exponents
- Multiply
- Divide
- Add
- Subtract
<h3>-3(10)</h3>
<u>First, remove parenthesis.</u>
<u />
<u>Multiply.</u>
-3*10
<u>Solve.</u>
<u>-30</u>
- <u>Therefore, the correct answer is -30.</u>
I hope this helps you! Let me know if my answer is wrong or not.
Answer:
The intensity of the 2012 earthquake was about 126 times the intensity of the 1952 earthquake.
Step-by-step explanation:
To compare the intensities, we first need to convert the magnitudes to intensities using the log formula. Then we will set up a ratio to compare the intensities.
Convert the magnitudes to intensities and convert to exponential form.
R=logI
2012 earthquake:
8.6I=logI=108.6
1952 earthquake:
6.5I=logI=106.5
Form a ratio of the intensities.
intensity for 2012intensity for 1952
Substitute in the values and divide by subtracting the exponents to find
108.6106.5102.1≈126.
The intensity of the 2012 earthquake was about 126 times the intensity of the 1952 earthquake.
Your answer:
The intensity of the 1952 earthquake was about 110 times the intensity of the 2012 earthquake.
Remark
What you have to do to learn the difference between recursive and explicit is try try the first 3 or 4 terms to see what you have and how you did it.
a1 = - 3
a2 = - 3 (1/8) = -3 / 8
a3 = (a2) (1/8)
a3 = (-3/8) * 1/8
a3 = (- 3/64)
a4 = a3 (1/8)
a4 = -3/64 * 1/8
a4 = - 3 / 512
Take a good look at a4. What do you notice? No matter what, you are always multiplying by 1/8. That means that A and D are both wrong which they would have you raising by 3 or - 3 to some power.
So which one of B and C is correct?
The answer is which ever one will not change sign from what it started out with. All four terms are minus.
In B the term is multiplied by plus 1/8. That will not change the sign of the next term.
So the answer is
a_n = - 3 * (1/8)^(n - 1) <<<<< answer
Answer:
Total of 9 lengths of 4 inches can be taken out from a board of 3 feet
Step-by-step explanation:
length of board in feet = 3 ft
As
1 ft = 12 inches
So
Length of board in inch = 
= 36 inches
Let no of 4 inches length be = x
The equation become
Total of 9 lengths of 4 inches can be taken out from a board of 3 feet
