Given y inversely proportional to x and x = 3 for y = 4, what is x if y = 12?

A.) 1
B.) 9
C.) 16

Answers

Answer 1

B

12 is equal to 4y, or 4(3)

you can multiply 4 by x to get 9 since they’re inversely proportionate.

Answer 2

Answer:

A) 1.

Step-by-step explanation:

y is inversely proporcional to x so the equation has the form:

y = c/x

With c been any constant, to find the value of c we use y=4 and x=3:

4 = c/3

c=4*3

c=12

So the equation is

y=12/x

Using y=12 to find x:

12=12/x

(12/12)=x

x=1

Which expression is equivalent to sqrt 10 / 4 sqrt 8

Answers

Answer:

Step-by-step explanation:

Keep in mind that we want to eliminate the radical from the denominator.  Note that the denominator is equal to

8^(1/4) = (2^3)^(1/4).

If we multiply the entire given expression by 2^(1/4), we get:

2^(1/4)           √10

----------- * -----------------

2^(1/4)       (2^3)^(1/4)

or

2^(1/4)           √10            2^(1/4) · √10          2^(1/4) · 10^(2/4)    

----------- * ----------------- = ---------------------- = ---------------------------

2^(1/4)       (2^3)^(1/4)         2^(1/4 + 3/4)                2                          

    2^(1/4) · 10^(2/4)           2^(1/4) · 100^(1/4)        200^(1/4)

n-2/180

(n-1) 180

180/n-1

(n-2) 180

Answers

Answer:

D.

Step-by-step explanation:

The formula is Sum(n) = (n -2) 180.

The polygon angle sum theorem states that the sum of the measures of the interior angles of an n-gon is (n-2) 180

What is a polygon or an n-gon?

A polygon is a geometric figure with a finite number of sides in 2D. A polygon's sides are made up of straight-line segments. They are called as sides. The intersection of two line segments is known as the vertex and an angle is generated as result.

The term n-gon refers to polygon with n sides.

What are the interior angles of a Polygon or an n-gon?

A polygon's interior angle is the angle formed between two adjacent sides of the polygon.

How to find the sum of the measures of the interior angles of an n-gon?

We will take a pentagon(5 sides) and then we will try to generalize it to an n-gon(n sides) with the following steps:

In the figure let's take the vertex B and connect all the other vertices to it.Now, look there are a total of 3 triangles formed inside the pentagon.So, now we can say if we add connect all the vertices of an n-gon from a random vertex it will produce a total of (n-2) triangles in it.
What is the sum of the interior angles of a triangle?

The sum of the interior angles of a triangle is 180°

Now, each triangle has the sum of interior angles of 180°,

so (n-2) triangles will have the sum of interior angles of (n-2)×180°.

Therefore, the sum of the measures of the interior angles of an n-gon is (n-2)×180.

Step-by-step explanation:

The mean is another way to say average.

Add the weights of all the polar bears together

3,280 kilograms total.

Then divide by the total number of bears

3,280 / 8 = 410

Answer:

Mean=410

Step-by-step explanation:

Given that the table shows the weights, in kilograms, of 8 polar bears.

Now we need to find about what is the mean weight of the polar bears.

So we just need to add all the weights then divide the sum by 8 to get the mean weight.

[tex]Mean=\frac{453+553+471+358+467+262+352+364}{8}[/tex]

[tex]Mean=\frac{3280}{8}[/tex]

If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w.r) (x)?

Answers

Final answer:

The range of (w.r)(x) is all real numbers.

Explanation:

The range of (w.r)(x) can be found by substituting the value of x from w(x) into r(x). So, we have:

(w.r)(x) = r(w(x)) = 2 - (x - 2)^2 = 2 - (x^2 - 4x + 4) = 6 - x^2 + 4x.

Therefore, the range of (w.r)(x) is all real numbers.

[tex]-6 <x <-4[/tex]        Increasing

[tex]-4 <x <-1[/tex]      Neither Increasing or Decreasing ​

Step-by-step explanation:

To know if the graph of a function is growing or decreasing you must use the graph to verify what happens when x increases.

If when x increases y decreases, then the function is decreasing.

If when x increases y increases, then the function is growing.

Let's look at the

First interval.

[tex]-13 <x <-12[/tex] Note that the value of y is always equal in this interval, therefore the function is not  increasing or decreasing.

Second interval

[tex]-12 <x <-9[/tex]

Note that when x increases from -12 to -10, the value of y increases from y = 1 to y = 3.

Then the function is  increasing in this interval

Third interval

[tex]-9 <x <-6[/tex]

Note that when x = -9 y= 8, but when x approaches -6 then y approaches 7.

Therefore in this interval the function is decreasing.

Fourth interval

[tex]-6 <x <-4[/tex]

When x = -6 y = 7 and at the end of the interval when x = -4 then y = 11

The function is increasing.

Fifth interval

[tex]-4 <x <-1[/tex]

The value of y remains constant throughout the interval. So the function is not  increasing and it is not decreasing

happy to help

Final answer:

Set A represents a function because each element of its domain is paired with a unique element in the range. Set B does not represent a function because it has repeated first elements without unique corresponding second elements.

Explanation:

The question asks which set of ordered pairs represents a function. A function is a special type of relation where each element of the domain (the first element in each ordered pair) is paired with a unique element in the range (the second element in each ordered pair). Analyzing option A, we see that each first element in the set A = {(1, −2), (3, −5), (5, 2), (7, 5)} is unique, which means it represents a function. However, for option B, we have repeated first elements in the set B = {(4, 2), (4, −2), (9, 3), (9, −3)}, which means it does not meet the criteria for a function as the first element, which belongs to the domain, is not mapped to a unique value in the range.


If y is 4.5 when x is 3, and y varies directly with x, find y when x is 9. 1.5 7.5 10.5 13.5

Answers

ANSWER

13.5

EXPLANATION

It was given that, y varies directly as x.

Therefore, the variation equation is of the form:

[tex]y = kx[/tex]

If y is 4.5 when x is 3, then we can substitute to find the constant of variation.

[tex]4.5 = 3k[/tex]

Divide both sides by 3;

[tex]k = \frac{4.5}{3} [/tex]

[tex]k = \frac{3}{2} [/tex]

Hence the equation becomes:

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

When x=9,

[tex]y = \frac{3}{2} \times 9 = 13.5[/tex]
