Answer:

C

Step-by-step explanation:

Here, originally, we are told that the point Q has coordinates (-2,1)

Now, its dilated point has the coordinates (-8,4)

what we can observe here is the the shape original polygon was dilated by a factor of 4 to give the image

Now the point R’ is (0,8)

To get the point R , we simply divide each coordinate by 4

Thus, we have (0/4 , 8/4)

This is same as option C

Answer:

The greatest of the four integers is 14.

Step-by-step explanation:

Let x be the first integer.

x + (x + 1) + (x + 2) + (x + 3) = 50

4x + 6 = 50

4x = 44

x = 11

11 + 12 + 13 + 14 = 50

The number of blue balloons will be equal to 45.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the ratio of red balloons to blue balloons at a party is 4 to 9. There are 20 red balloons. The number of blue balloons will be calculated as below:-

4/9 to 20/x

Cross multiply and divide to get your answer.

4 / 9 = 20 / x

4x=180

x=45

Therefore, the number of blue balloons will be equal to 45.

Answer:

5.555

Step-by-step explanation:

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

From this graph we should determine two points so we can work out the slope. Let's take points (3, -4) and (6, -2).

The equation to find the slope is:

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

Let's substitute in our values:

m = [tex]\frac{-2 - -4}{6 - 3}[/tex]

Remember that two negatives make a positive, let's solve for m:

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

Okay, now we have the value of m. Now we need the value of b. We can determine this by looking at the graph and looking where the line passes through the y-axis. In this graph, we can see the line pass through the y-axis at point (0, -6).

Therefore we can determine that b = -6.

Let's substitute our value for m and our value for b into the slope-intercept formula:

y = mx + b

y = [tex]\frac{2}{3}[/tex]x + -6

There's your final answer! I hope this helps, have a great night. :)

Statements are;

1) S(q) represents a quantity that changes at a constant rate per unit interval.

2) S(q) represents a quantity that changes at a constant percent rate per unit interval

3) S(q) represents a linear function

4) S(q) represents an exponential function.

Answer:

Statements 1 & 3 are true while statements 2 & 4 are false

Step-by-step explanation:

We are told that S(q) is a function that represents the quiz score, S, in terms of the number of correctly answered questions, q.

Statement 1 is true because the quiz score(S(q)) changes at a constant rate per unit questions answered since the math quiz has 10 questions and is scored out of 100

Statement 2 is false because S(q) is not expressed as a percentage rate.

Statement 3 is correct because S(q) function is a straight linear functional relationship where it directly depends on the number of correctly answered questions(q)

Statement 4 is false because the relationship is not expressed in exponential form but as a direct linear relationship.

The function S(q) is an illustration of a linear function.

The true statements are:

The false statements are:

From the question, we understand that:

S(q) represents the quiz score in terms of the number of correct answers

This means that:

As the correct answers increases or decreases, the value of s(q) changes at a constant interval

Functions that have such behavior are linear functions because they change at a constant rate

Hence, (a) and (c) are true, while (b) and (d) are false.

Answer:

Volume of cone is: 47464.23 dm³

Step-by-step explanation:

We are given:

Radius of cone r = 35 dm

Slant Height of cone h = 37 dm

We need to find Volume of the cone.

The formula used to find Volume is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]

Putting values and finding volume:

[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14*(35)^2 *\frac{37}{3}\\Volume=47464.23\ dm^3[/tex]

So, volume of cone is: 47464.23 dm³

Step-by-step explanation:

Step 1: Set up equation

tan55° = 19/x

Step 2: Solve for x

And we have our final answer!

Answer:

13.3

Step-by-step explanation:

This is trigonometry

So for this one, we use a basic ratio. We need to use 19 and 55 degrees for the answer. We are given that the leg adjacent to the 55-degree angle is x and the opposite leg to the 55-degree angle is 19.

So we use tangent(opposite leg/adjacent leg) for this (TOA of SOH CAH TOA)

tan(55 degrees)=19/x

  SO then solve for x and then evaluate using a scientific calculator and you should get 13.30394322

Given:

The vertices of ΔWXY are W(-10, 4), X(-3, -1), and Y(-5, 11).

To find:

Which type of triangle is ΔWXY by its sides.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using distance formula, we get

[tex]WX=\sqrt{(-3-(-10))^2+(-1-4)^2}[/tex]

[tex]WX=\sqrt{(-3+10)^2+(-5)^2}[/tex]

[tex]WX=\sqrt{(7)^2+(-5)^2}[/tex]

[tex]WX=\sqrt49+25}[/tex]

[tex]WX=\sqrt{74}[/tex]

Similarly,

[tex]XY=\sqrt{\left(-5-\left(-3\right)\right)^2+\left(11-\left(-1\right)\right)^2}=2\sqrt{37}[/tex]

[tex]WY=\sqrt{\left(-5-\left(-10\right)\right)^2+\left(11-4\right)^2}=\sqrt{74}[/tex]

Now,

[tex]WX=WY[/tex]

So, triangle is an isosceles triangles.

and,

[tex]WX^2+WY^2=(\sqrt{74})^2+(\sqrt{74})^2[/tex]

[tex]WX^2+WY^2=74+74[/tex]

[tex]WX^2+WY^2=148[/tex]

[tex]WX^2+WY^2=(2\sqrt{37})^2[/tex]

[tex]WX^2+WY^2=WY^2[/tex]

So, triangle is right angled triangle.

Therefore, the ΔWXY is an isosceles right angle triangle.
