The statement, "If m∠X ≅ m∠Y and m∠Y ≅ m∠Z, then m∠X ≅ m∠Z" demonstrates: D. the transitive property.

In geometry, the transitive property of congruency states that when two angles, sides, or triangles are congruent to a third angle, side, or triangle, then all three angles, sides, or triangles will be congruent to each other.

Illustrating the transitive property, if a = b, and b = c, therefore, a = b = c. We can then state that a = c.

Therefore, given that If m∠X ≅ m∠Y and m∠Y ≅ m∠Z, then m∠X ≅ m∠Z, we have:

Two angles, X and Z, which are both congruent to a third angle, Y.

Therefore, based on the transitive property, we can state that all three angles are congruent to each other, which leads us to conclude that:

m∠X ≅ m∠Z.

Thus, the statement given demonstrates the: D. transitive property.

(a) Similar due to SSS and a scale factor of 3.5. Triangle QRS is similar to triangle VUT.

(b) Similar to due SAS and a scale factor of 0.29. Triangle QRS is similar to triangle TUV.

(c) Similar due to AA. Triangle QRS is similar to triangle VUT.

(d) Similar due to SSS and a scale factor of $0.29$. Triangle QRS is similar to triangle VUT.

As we know that, the ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor.

Since the both triangle area similar so using the SSS theorem;

Triangle QRS congruence to triangle VUT.

QR/VU = RS/UT = SQ/TV

So QR/VU = 56/16; RS/UT = 70/20; SQ/TV = 98/28

QR/VU = RS/UT = SQ/TV = 3.5

Hence, ΔQRS≈ΔVUT using the SSS theorem with the scale factor of 3.5. So the option 1 "Similar due to SSS and a scale factor of 3.5. Triangle QRS is similar to triangle VUT." is correct.

Using division, we know that the total number of students that wil plant 1280 plants are 256 in grade 5.

Division's opposite is multiplication.

If 3 groups of 4 total up to 12, then 4 are in each group when 12 is divided into 3 equal groups.

The fundamental goal of division is to produce equal groups or to ascertain how many individuals are in each category following a fair distribution.

So, we know that each student plant 5 trees.

In all, total 1280 plants were planted.

Then, calculate the number of studensts that planted 1280 plants as follows:

The slope intercept form is y= ( -3/2 ) x + 7/2

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

(x1,y1)= (3. -1) and (x2,y2)= (5, -4)

slope intercept form:

y=mx+b , m=slope, b = constant

m= (y2-y1) /( x2-x1) = (-4-(-1)) / ( 5-3) =  -3/2

line equation:

y-y1=m(x-x1)

Substitute the values

y-(-1)=( -3/2 ) (x-3)

y+1=( -3/2 ) x + 9/2

y= ( -3/2 ) x + 9/2 - 1

y= ( -3/2 ) x + 7/2

The equation of the conic represents a circle with an area of 36π square units.

In this problem we find the equation of the conic in general form, on which we need to determine what kind of conic it represents. This can be done by finding the standard form of the equation by means of algebra properties, using a strategy known as completing the square. The quadratic equation in general form is described by the quadratic equations of the form:

A · x² + B · y² + C · x + D · y + E · x · y + F = 0

Now we proceed to find the standard form of the equation. First, write the equation in standard form:

x² + y² - 3 · x + 6 · y = 7 · x + 2

x² + y² - 10 · x + 6 · y - 2 = 0

Second, complete the square:

(x² - 10 · x + 25) + (y² + 6 · y + 9) = 2 + 25 + 9

(x - 5)² + (y + 3)² = 36

The standard form of the quadratic equation indicates the equation of a circle with a diameter of 12 units and a center at (h, k) = (5, - 3). The area of the circle is calculated below:

Step-by-step explanation:

You want to know the number of devices without defect if 3% of a day's production of 784 devices are defective.

The number of defective devices produced in a day is expected to be ...

  3% × 784 = 23.52 ≈ 24 . . . . devices

The number without defect will be the remaining number of devices:

  784 -24 = 760

About 760 devices are without defect.

The angles in the parallel lines are as follows;

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, linear angles, vertically opposite angles etc.

Therefore, let's find the angles m∠1 and m∠2.

Hence,

138 + m∠1 = 180(angles on a straight line)

The sum of angles on a straight line is 180 degrees.

m∠1 = 180 - 138

m∠1 = 42 degrees

Therefore,

m∠1 =  m∠2 (alternate exterior angles)

Alternate exterior angles are the pair of angles that are formed on th outer side of the parallel lines but on the opposite side of the transversal.

Alternate exterior angles are congruent.

Therefore,

m∠1 =  m∠2 = 42 degrees.

The value of the given composite function f(g(x)) at x = -1 is that f(g(-1)) will be 6.2.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given function f(x) and g(x) are linear functions.

Take (-6,6) and (-1,5)

The equation will be as follows,

f(x) - 6 = (5 - 6)/(-1 + 6)(x + 6)

f(x) - 6 = -x/5 - 6/5

f(x) = -x/5 - 6/5 + 6

f(x) = -x/5 + (- 6 + 30)/5

f(x) = -x/5 + 24/5

Take (-6,-12) and (-1,-7)

g(x) + 12 = (-7 + 12)/(-1 + 6)(x + 6)

g(x) + 12 = x + 6

g(x) = x - 6

Now, f(g(x)) = -(x - 6)/5 + 24/5

f(g(-1)) = -(-1 - 6)/5 + 24/5

f(g(-1)) = 7/5 + 24/5 = 6.2

Hence "At x = -1, the value of the composite function f(g(x)) is that f(g(-1)) will be equal to 6.2.".

Answer:

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity. The degree (which comes from the exponent on the leading term) and the leading coefficient (+ or –) of a polynomial function determines the end behavior of the graph.

Step-by-step explanation:   hope this helps!

The function approaches negative infinity as x approaches positive infinity and the function approaches negative infinity as x approaches positive infinity. Option C is correct.

The end behavior of a polynomial function describes the behavior of the function as x becomes very large in either the positive or negative direction.

As x approaches negative infinity, the function becomes more and more positive. As x approaches positive infinity, the function becomes more and more negative.

As x → -∞, y → ∞

As x → +∞, y → -∞

r = 4 feet

Put in your values:

[tex]\frac{1}{3}[/tex](4)²(3.14)h = 189 ft³

16(3.14)h = 567

50.24h = 567

h = [tex]\frac{567}{50.27}[/tex] = 11.3

The height of the cone is h = 11.3 feet

In geometry,  a cone is a three-dimensional shape formed by joining a set of line segments from a common point called apex to all the points of the base which is a circle.

Height of the cone is distance from apex to the center of the circular base.

Volume of a cone is defined as the total capacity of the cone and the formula for the same is given by,

V = [tex]\frac{1\\}{3}[/tex]πr²h

Here, V = 189 ft³, r = 4 ft, π = 3.14

Substituting these values in formula for the volume,

189 = [tex]\frac{1}{3}[/tex] × 3.14 × 4² × h

189 = [tex]\frac{50.24}{3}[/tex]h

h = 189 × 3 / 50.24

h = 11.285 ≈ 11.3

Answer:

The surface area of the box is 52 square meters. To calculate the surface area of a rectangular box, we need to find the area of each face and then add them together. In this case, the box has six faces, each with a different length and width. The top, bottom, and side faces are all rectangular, while the front and back faces are also rectangular but have a different size.

To find the surface area of the box, we can start by finding the area of the top and bottom faces. The top and bottom faces are both 2 meters by 4 meters, so the area of each face is 2 * 4 = 8 square meters. Therefore, the total area of the top and bottom faces is 8 * 2 = 16 square meters.

Next, we can find the area of the front and back faces. The front and back faces are both 3 meters by 2 meters, so the area of each face is 3 * 2 = 6 square meters. Therefore, the total area of the front and back faces is 6 * 2 = 12 square meters.

Finally, we can find the area of the side faces. The side faces are both 3 meters by 2 meters, so the area of each face is 3 * 2 = 6 square meters. Therefore, the total area of the side faces is 6 * 2 = 12 square meters.

To find the total surface area of the box, we need to add the areas of the top, bottom, front, back, and side faces together.
