The mapping diagram displays how inputs are transformed into outputs; this relationship must match the transformation properties of the given functions to determine the correct answer.

To understand which function is represented by the mapping diagram, one needs to look at how the inputs (or arguments) are being transformed into outputs (or values). A mapping diagram shows a set of ordered pairs, illustrating how each input is associated with a specific output. Considering the functions given: F(x) = x+3, F(x) = x-3, F(x) = 3x, and F(x) = 1, it is important to note the nature of transformations that each of these functions imply.

For the F(x) = x+3 function, every input value x is increased by 3, which is a shift to the right on the graph. On the other hand, F(x) = x-3 would decrease every input x by 3, showing a leftward shift. If we consider F(x) = 3x, this would imply each input x is being scaled by a factor of 3. Lastly, F(x) = 1 represents a constant function that maps every input to the same output, which is 1.

To determine the correct function from the mapping diagram, one would compare these transformations to the mapping shown and select the function that accurately describes the relationship between the inputs and outputs in the diagram.

Answer:

18

Step-by-step explanation:

Volume is a product of cross-sectional area and height and relresented as V=Ah where V is volume, A is cross-sectional area and h is height.

For the square, since each has a thickness of 6mm then for 24 of them the height will be 24*6=144 mm

Since the volume and cross sectional area of the triangle should be the same, then the height should also be the same.

Since for the triangle each has a thickness of 8mm then the number requred to achieve a height of 144 mm will be 144/8=18 stacks

To find the number of triangular cutouts needed for the oblique stack to have the same volume as the upright stack, we need to compare the volumes of the two shapes. The volume of a square cutout is 6mm × (the area of the square cross-section), while the volume of a triangular cutout is 8mm × (the area of the triangular cross-section).

To find the number of triangular cutouts needed for the oblique stack to have the same volume as the upright stack, we need to compare the volumes of the two shapes. The volume of a square cutout is 6mm × (the area of the square cross-section), while the volume of a triangular cutout is 8mm × (the area of the triangular cross-section).

Since both stacks have the same area of cross-section, we can set up the equation 6mm × (area of a square) × 24 = 8mm × (area of a triangle) × (number of triangular cutouts). By finding the ratio of the volumes and solving for the number of triangular cutouts, we can determine the number needed.

Given:

Vertical angles.

One angle is 85°.

To find:

The measure of ∠1, ∠2 and ∠3.

Solution:

∠2 and 85° are vertically opposite angles and ∠1 and ∠3 are vertically opposite angles.

Vertical angle theorem:

If two lines are intersecting, then the vertically opposite angles are congruent.

⇒ m∠2 = 85°

Sum of the adjacent angles in a straight line = 180°

m∠2 + m∠3 = 180°

85° + m∠3 = 180°

Subtract 85° from both sides.

85° + m∠3 - 85° = 180° - 85°

m∠3 = 95°

By vertical angle theorem:

⇒ m∠1 = m∠3

⇒ m∠1 = 95°

Therefore m∠1 = 95°, m∠2 = 85° and m∠3 = 95°.

Answer:

[tex]9\pi[/tex]

Step-by-step explanation:

I don't see a picture, so I'm assuming the cylinder looks like a soup can sitting on a table, resting on it's circular base.

The base of the cylinder is a circle, so you need to find the area of a circle with diameter 6.  Use the formula

[tex]A=\pi r^2[/tex] where r is the radius of the cylinder.  If the diameter is 6, then the radius is 3.

[tex]A=\pi (3)^2 = 9\pi[/tex]

Answer:

36

Step-by-step explanation:

That kind of triangle is supposed to equal up to 180. So 65 + 79 = 144. So 180 - 144 = 36. Sorry if this is the wrong answer. This is what i think it is. Again, sorry in advanced!

Sum is always 1

Step-by-step explanation:

The sum of probability of an event and its complementary event is always 1.

Here, the event is rolling an even number. Let it be P(even)

Its complementary event is rolling a number that is not even. Let it be P(not even)

P(even) = 1/6

P(not even) = 5/6

P(even) + P(not even) = 1/6 + 5/6 = 1

Answer:

yes because the no's.are different and they are moving high in the graph

The graph represents changing speed, and the average speed is 0.5 meters per second.

To determine whether the graph represents constant or changing speed, we examine the relationship between distance and time.

If the speed remains consistent over time, the graph represents constant speed.

Conversely, if the speed varies, the graph represents changing speed.

Upon examining the data provided, we observe that the distance traveled increases as time progresses, indicating changing speed.

This inference arises because the increments in distance over successive time intervals are not consistent, suggesting acceleration or deceleration.

To find the average speed, we divide the total distance traveled by the total time taken. In this case, the total distance covered is 100 meters (from 10 to 100 meters), and the total time elapsed is 200 seconds (from 20 to 200 seconds).

Therefore, the average speed is:

[tex]\[ \text{Average speed} = \frac{\text{Total distance}}{\text{Total time}} = \frac{100 \, \text{m}}{200 \, \text{s}} = 0.5 \, \text{m/s} \][/tex]

Hence, the graph represents changing speed, and the average speed is 0.5 meters per second.

The probable question may be:

Does this graph represent constant or changing speed? How do you know?

When a circle is inscribed in a triangle, its radius is equal to the distances between the points of tangency on each side and the center of the circle.

When a circle is inscribed in a triangle, it is tangent to all three sides of the triangle.

The perimeter of the triangle can be found by adding the lengths of the three sides.

Since the circle is inscribed in the triangle, the lengths of the sides of the triangle are equal to the distances between the points of tangency on each side and the center of the circle.

Therefore, the perimeter of the triangle is equal to the sum of these distances.

[tex]\boxed{\angle DBC=x=60^{\circ}}[/tex]

Hello! Remember to write complete questions in order to get good and exact answers. Here the figure is missing so I'll assume the arc measure of DBC is given in radian and you want it in degrees. By definition, an arc's measure is the measure of its central angle being a central angle an angle between two radii in a circle. Suppose that angle measures:

[tex]\angle DBC=\frac{\pi}{3}\ radian \\ \\ \\ So, \ by \ rule \ of \ three: \\\\ \\ \pi \ radian \rightarrow 180 \ degrees \\ \\ \pi/3 \ radian \rightarrow x \ degrees \\ \\ \\ x =\frac{180\pi}{3\pi}=60^{\circ} \\ \\ \\ Finally: \\ \\ \boxed{\angle DBC=x=60^{\circ}}[/tex]

Answer: 20 :)

Step-by-step explanation:

Solution:

Given that,

Jamal has 2 straight sticks with the length of 20 cm and 18 cm

Jamal searches for a third stick so that he can form a triangle

According to triangle inequality theorem,

Triangle inequality theorem states that sum of length of two sides of triangle should always be greater than measure of third side

Let the length of unknown side be "x"

Case 1:

Let 20 cm be the length of third side

Then,

x + 18 > 20

x > 20 - 18

x > 2

Case 2:

Let "x" cm be the length of third side

18 + 20 > x

38 > x

x < 38

This means that length of third side of triangle should be greater than 2 and less than 38

Final answer:

Jamal can use any third stick with a length greater than 2 cm and less than 38 cm to form a triangle with his existing sticks of 20 cm and 18 cm, according to the triangle inequality theorem.

Explanation:

To determine the length of a third stick that Jamal can use to form a triangle with the other two sticks, one must apply the triangle inequality theorem. The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In Jamal's case, the sticks have lengths of 20 cm and 18 cm. Therefore, the length of the third stick must be more than the difference of the two sticks and less than their sum to form a triangle.

So the third stick must be longer than 2 cm (20 cm - 18 cm) and shorter than 38 cm (20 cm + 18 cm). To summarize:

So any stick length between > 2 cm and < 38 cm will allow Jamal to create a triangle with the other two sticks.
