Answer:
0.28 and 4.48
Step-by-step explanation:
c) You have to find the number by which the numbers in the list get multiplied.
If you divide the third number 1.12 by the first 0.07, you get 16. To get from 0.07 to 1.12, the 0.07 was multiplied twice by this number. 16=4*4, so the multiplier is 4.
Now it is possible to calculate the whole series:
0.07 * 4 = 0.28
0.28 * 4 = 1.12
1.12 * 4 = 4.48
4.48 * 4 = 17.92
d) divide the second by the first number:
So work with factor 10/11 to calculate the series:
11/10, 1, 10/11, 100/121, 1000/1333, ...
g) Divide 7/12 by 2/3 to find 7/8. So the number preceding 2/3 is (2/3) / (7/8) = 16/21 and the numbers after 7/12 are:
(7/12) * (7/8) = 49/96
and
(49/96) * (7/8) = 343/768

<----------(-4)--------(-2)--------(0)--------(-2)----------(4)-------------->
x>4 or x<-4
Step-by-step explanation:
You are looking for numbers that give you a distance, x, greater than 4 from 0. That wouldn't be anything between -4 and 4 because these would all give you a distance less than 4 from 0. So the answer would be to shade everything greater than 4 while also shading everything less than -4.
Here is a number line <-----|-----|-----|-----|-----|-----|-----|-----|-->
-6 -4 -2 0 2 4 6 8
Let's think about this more which of these numbers on this number line would satisfy |x|>4?
Numbers inside the numbers -4 and 4.
Or the numbers on the outside.
Let's try the inside numbers:
-2,02
|-2|>4
2>4 is false which means -2 doesn't satisfy |x|>4
|0|>4
0>4 is false which means 0 doesn't satisfy |x|>4
|2|>4
2>4 is false which means 2 doesn't satisfy |x|>4
We could also try -4 and 4... but these will both give you a distance equal to 4 from 0. And we are looking for greater than.
|-4|>4
4>4 is false which mean -4 doesn't satisfy |x|>4
|4|>4
4>4 is false which means 4 doesn't satisfy |x|>4
Now let's try the numbers on the outside:
-6,6,8
|-6|>4
6>4 is true so -6 does satisfy |x|>4
|6|>4
6>4 is true so 6 does satisfy |x|>4
|8|>4
8>4 is true so 8 does satisfy |x|>4
So what I'm trying to do is convince you more that the only numbers that would satisfy |x|>4 are numbers outside the interval from -4 to 4.
So x>4 or x<-4.
On a number line the solution would look like this:
***********o o**************
<----------(-4)--------(-2)--------(0)--------(-2)----------(4)-------------->
We have holes at -4 and 4 to mean we do not include those numbers. We would have if the inequality read . The line underneath this inequality means to include or equals. We do not want to include; we did not have the equal sign. The only difference between the two solutions would be to fill the holes if you
