1.1.3 what is a function? Question 5 out of 10 Mark all the statements that are true


A. The domain for this function is the set {-5}

B. The range for this function is the set {-5}

C. All real numbers are in the range of this function

D. The domain for this function is all real numbers

C. This graph is not a function because the value of Y is the same for every value of X

Answer:

no, because y does not change by 5 every time x changes by 1

Step-by-step explanation:

The answer is C btw

C:No, because y does not change by 5 every time x changes by 1.

The function graphed below is not continuous.

On the graph at x = 0, the function is not continuous. There is a jump on the graph at x = 0.

A function is said to be continuous if the graph of the function has no break, hole or asymptotes.

In this graph it is clear that the graph is not continuous because the function approaches -4 until when x = 0 and then after x = 0, function takes the values from 1.

This causes a jump on the graph of the function which gives a discontinuity at x = 0.

a) -5/-6

b) 5/-6

c) -5/6

d) 4/-6

From the format of -4/9 and -7/8 you can deduct that it is either A or C, -5/-6 (a) will be a positive decimal so therefore the answer is C because it is the only fraction in the correct format that has an answer on between the two in the problem.

Answer:

so the equation would be 4x (because he buys 4 books) + 0y (because he didn't buy any CDs) = 32 (or it could be $32). The slope would be 4.

Step-by-step explanation:

The sample percentage (p) represents the proportion of people in a sample who have a particular attribute or trait. The correct option is A.

The sample percentage (p) represents the proportion of people in a sample who have a particular attribute or trait. Divide the number of persons (or objects) who have the characteristic of interest by the total number of people (or items) in the sample to get the sample proportion.

Given there are 36 successful outcomes in a sample with a size of 80. Therefore, the sample proportion is,

Sample proportion = 36/80 = 0.45

Hence, the correct option is A.

Steps in order will be

[tex]1. y=\sqrt{7x-21}\\2. y^2=7x-21 \\ 3. y^2=7(x-3)\\4. \frac{y^2}{7}=x-3\\ 5. x=\frac{y^2}{7}+3\\6. f^{-1}(x)=\frac{1}{7}x^2+3 \:where\: x\geq 0[/tex]

Step-by-step explanation:

Consider the function [tex]f(x)=\sqrt{7x-21}[/tex]

We need to find [tex]f^{-1}(x)[/tex]

For finding [tex]f^{-1}(x)[/tex]  replace f(x) with y

Step 1: Replace f(x) with y

[tex]y=\sqrt{7x-21}[/tex]

Now, solve for x

Step 2: Taking square on left side

[tex]y^2=(\sqrt{7x-21})^2\\y^2=7x-21[/tex]

Step 3 : take 7 common

[tex]y^2=7(x-3)[/tex]

Step 4 : Divide both sides by 7

[tex]\frac{y^2}{7}=x-3[/tex]

Step 5: Add 3 on both sides

[tex]\frac{y^2}{7}+3=x-3+3\\x=\frac{y^2}{7}+3[/tex]

Step 6: Replace x with y and x with [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x)=\frac{1}{7}x^2+3[/tex] where x≥0

Steps in order will be

[tex]1. y=\sqrt{7x-21}\\2. y^2=7x-21 \\ 3. y^2=7(x-3)\\4. \frac{y^2}{7}=x-3\\ 5. x=\frac{y^2}{7}+3\\6. f^{-1}(x)=\frac{1}{7}x^2+3 \:where\: x\geq 0[/tex]

An aristocracy is similar to a monarchy because people are born into their positions. Option C is correct.

Given that,
To discuss how aristocracy is similar to a monarchy.

In mathematics, it deals with numbers of operations according to the statements.

Here,
Monarchy is a system of governance in which one or more people hold all the power and authority. Aristocracy, on the other hand, is a type of government in which the power is held by a small number of individuals who are typically thought to be the most competent members of the community.

Thus, An aristocracy is similar to a monarchy because people are born into their positions. Option C is correct.

Step-by-step explanation:

In order to name a plane, you need to name at least 3 points in that plane, which are not in line.

Answer:

The graph of y > mx, where m > 0, consists of a dashed line and a shaded half-plane. The line has a positive slope and passes through the origin. The shadow of the half plane is above the line. m<0 means slope is negative

b>0 means the line will intersect the y axis above 0. Since the slope is positive, the graph is increasing.  So like stated above The boundary line is dashed, and everything above it is shaded.

Answer:

Xavier will not be able to qualify because the speed required for him to qualify is greater than the speed at which he runs

Step-by-step explanation:

Here, we want to know if Xavier will be able to qualify or not

His constant speed is 5/3 m/s

Now to win , he needs a speed of 100 m/55 sec = 20/11 m/s

So now, we need to know the bigger fraction between the two

Mathematically, that will be

5/3 - 20/11 = (55-60)/11 = -5/11

As we can see, the required speed is greater than what he can run

So this means that he will not be able to qualify

Answer:

122.5 People

Step-by-step explanation:

4500-90 = 4410

4410 divided by 36 equals 122.5

==========================================================

Explanation:

n = number of people invited

n+2 = total number of people after adding Oscar and Julie

36(n+2) = total cost before the $90 fee

36(n+2)+90 = total cost after the $90 fee

Set that equal to the budget of 4500 and isolate n

36(n+2)+90 = 4500

36n+72+90 = 4500

36n+162 = 4500

36n = 4500-162

36n = 4338

n = 120.5

n = 120

We round down so that we don't go over budget

Oscar and Julie can invite 120 people.

-----------

Check:

If n = 120 then 36(n+2)+90 = 36(120+2)+90 = 4482 which is under budget

If n = 121 then 36(n+2)+90 = 36(121+2)+90 = 4518 which is over budget

This confirms that 120 is the answer.

Answer:

x = 0.5

Step-by-step explanation:

Given

- 8.25x + 12 - 1.75x = 10.5x + 1.75 , that is

- 10x + 12 = 10.5x + 1.75 ( subtract 10.5x from both sides )

- 20.5x + 12 = 1.75 ( subtract 12 from both sides )

- 20.5x = - 10.25 ( divide both sides by - 20.5 )

x = 0.5
