Which describes all of the values for which the graph is positive and decreasing?A.all real values of x where x < −1
B.all real values of x where x < 1
C.all real values of x where 1 < x < 3
D.all real values of x where x > 3

Answers

Answer 1
Answer: The statement that describes all of the values for which the graph is positive and decreasing is:

C.) ALL REAL VALUES OF X WHERE 1 < X < 3

The number 1 ensures that the value of x will remain positive.
Since x is less than 3, then the value of x is decreasing.
Answer 2
Answer:

Answer:

c

Step-by-step explanation:

The number 1 ensures that the value of x will remain positive.

Since x is less than 3, then the value of x is decreasing.

What proportion of the first 10,000 natural numbers contain a 3

Answers

we know that

It is much easier to compute the number of numbers that do not contain a 3.

In the first 10 numbers 9 do not contain a 3.

In the first 100 numbers 81 do not contain a 3. (This is because these numbers are formed by selecting a digit out of

[0, 1, 2, 4, 5, 6, 7, 8, 9] for the first position and another digit out of the same set for the last position and this may be done in

9*9 = 81 ways.

In the first 1000 numbers, reasoning as above, there are

9^(3) numbers that do not contain a 3.

Now the pattern should be becoming obvious.

In the first 10^(n) numbers there are 9^(n) numbers that do not contain a 3.

So

In the first 10^(4) numbers there are 9^(4) numbers that do not contain a 3.

9^(4)= 6,561

10,000- 6,561= 3,439

Thus

the ratio of those numbers that do contain a 3 over the total is equal to

Ratio=(3,439)/(10,000) \n \n Ratio=0.3439

therefore

the answer is

0.3439
In the first 10 -> 10 - 9 = 1 (contain a 3).
In the first 100 -> 100 - 9 * 9 = 19 (contain a 3).
In the first 10^n -> 10^n - 9^n  (contain a 3).


So for 10^4 -> 10^4 - 9^4 = 10.000 - 6.561 = 3.439

The answer is 3.439 numbers contain a 3 in the first 10.000

24% of 1,321 is how much?

Answers

Percentage that needs to be determined = 24%
The quantity from which the percentage has to be determined = 1321
Then
24% of 1321 = (24/100) * 1321
                     = 31704/100
                     = 317.04
So from the above deduction we can easily say that 24% of the number 1321 is 317.04. I hope the procedure is not very complicated for you to understand. You can use this method for solving similar type of problems in future without requiring any help from anyone. Only be careful while calculating. Other than the calculation part, there is nothing tough about the problem.
