Triangle ΔABC is comparable to triangle ΔABC, which was formed after ABC's dilatation. The appropriate answers are The characteristics of dilations show that angles ∠B =∠ B'.

In Euclidean geometry, an angle is a shape made up of two rays, referred to as the flanks of the hook, that converge at the vertex of both the angle, which is located in the centre. Two rays may combine to form an angle in the plane in which they are positioned. Two planes colliding results in an angle as well. We refer to them as dihedral angles.

Here,

Assuming that A (0, -3), C (0, 5), and B are the triangle's vertices (6, 3)

Set point P to be (0, 0)

There is;

A' = 3/2 * (0,-3) = (0,-9/2) = (0,-4.5) (0,-4.5)

C' = 3/2 * (0,5) = (0, 15/2) = (0,7.5) (0,7.5)

B' = 3/2 * (6,6/3) = (9 , 9/2) = (9,4.5) (9,4.5)

Therefore, on a scale, the image of ABC is bigger than that of the image of A'B'C.

The proportion of the adjacent angles of ABC is given by a factor of 1.5.

since and "A'B'C" are both equal, the angle made by section BC and

BA,

AB/sin(C) = AC/sin(B)

AB/sin(C) = A'C'/A'B' = sin(B)/sin (C)

This means that

sin(B)/sin(C) = sin(B')/sin(C').

The complete question is "A. Dilate triangle ABC using center p and scale factor 3/2.

B. What do properties of dilations tell you about B'? (please answer B)"

As stated in the problem, the equation can be modeled by the equation:

[tex]y=0.35x[/tex]

The problem also defines the meaning of these variables:

y = bounce height in feet

x = release height in feet

Now, the question asks "If the ball is released from a height of 70 feet, what is the height the ball will achieve after the first bounce?"

From this question, we know that we want to solve for bounce height (y). We are also given the release height (x) of 70. Plug this value into the equation we were given at the start.

[tex]y=0.35(70)[/tex]

Now, just multiply the two values together:

[tex]y=24.5[/tex]

Therefore, we now know that the ball achieved a bounce height of 24.5 ft on the first bounce!

A photo with dimension 5 x 7 in is reduced so that the width becomes 4 in. The reduced size of the length of the photo is 5.6 in.

When two shapes are identical but differ in size, they are considered to be similar shapes. A similar shape can be created by scaling all of the lengths of the original shape. This means they've been stretched or shrunk in the same proportions. This is referred to as the scale factor.

In this case, the original photo and the smaller photo are similar shapes. Hence, the proportion of the corresponding sides have to be the same.

We can find the scale factor as:

Scale factor = reduced width / initial width

                   = 4 in. / 5 in. = 0.8

The length has to be reduces at the same scale factor. Therefore,

reduce length = 0.8 x 7 in = 5.6 in.

If is inversely proportional to x², then:

Given:

Substitute the given values into the found equation and solve for k:

Answer:

The dimensions of the larger triangle are 48 cm * 15 cm.

All these antiderivatives are equivalent as they are different ways of solving the same problem and differ only by a constant value.

What is an antiderivative?

An antiderivative, also known as a primitive function or indefinite integral, is the reverse operation of taking a derivative. In other words, if the derivative of a function f(x) is g(x), then f(x) is said to be an antiderivative of g(x).

The antiderivative of sin(x)cos(x) can be found using the product-to-sum identities:

(sin(x)cos(x))' = (sin(x)cos(x))'
                      = (1/2)(cos(2x) - sin(2x)) + C

Another way to find the antiderivative of sin(x)cos(x) is to use the chain rule:
(sin(x)cos(x))' = (sin(x))'cos(x) + sin(x)(cos(x))'
                     = -sin(x)cos(x) + cos(x)sin(x) + C

A third way is to use integration by parts, where we take u = sin(x) and dv = cos(x)dx. This gives us:
(sin(x)cos(x))' = sin(x)cos(x) - ∫cos(x)sin(x)dx + C

Another way is to use the substitution method, where we set u = cos(x) and du = -sin(x)dx. This gives us:
(sin(x)cos(x))' = sin(x)cos(x) + ∫-sin(x)cos(x)du + C

Lastly, we can use the trigonometric identity method where we use sin(2x) = 2sin(x)cos(x) and integrate.
This gives us: (sin(x)cos(x))' = (1/2)sin(2x) + C

Hence, All these antiderivatives are equivalent as they are different ways of solving the same problem and differ only by a constant value.

Answer: 180 degrees

Step-by-step explanation:

If there are two parallel lines such as we could see in the problem, you can basically carry some angles to the other corners if these corners show the same direction.

In this case, you can carry "a" angle to the corner which is at the top of the "b" angle. Then, you can notice that a and b angles are complementary to 180 degrees for each other. So, this is the answer.

Note: Actually, you can also realize that these two corners at the intersections of the lines should have the same angle otherwise there would be no parallelism.

A random sample variance is when a subset of individuals from a population is chosen using a random selection method, such as a random number generator, to ensure that each individual has an equal chance of being chosen.

A random sample is a type of sampling method used to select individuals from a population to form a sample. To generate a random sample, a list of all the individuals in the population must first be created. Each individual should be numbered consecutively. A random number generator, such as a computer or calculator, can then be used to generate a list of random numbers between 1 and the total number of individuals in the population. The individuals who correspond to the numbers generated by the random number generator form the sample. This ensures that each individual in the population has an equal chance of being chosen for the sample.

Let x = pounds of kind 1, and y = pounds of kind 2

x + y = 5 (total pounds of chocolate)

1.8x + 2.3y = 10 (cost of chocolate)

Solving the system of equations, you get x = 3.75 pounds of kind 1 and y = 1.25 pounds of kind 2. Jim can buy 3.75 pounds of kind 1 and 1.25 pounds of kind 2 for $10.

1.8x = 10 - 2.3y

x = (10 - 2.3y)/1.8

x + y = 5

x = 5 - y

(10 - 2.3y)/1.8 = 5 - y

2x - 12 = 10 ( add 12 to both sides )

Step-by-step explanation:

Amount earned from babysitting at $12/hour = 12B

Total amount earned = 12B + 8L

Each walkway is around 51 yards long.

Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.

The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).

Pythagoras is in the form of;

a²+b²=c²

However, it can also be written in the form of c²=a²+b²

In order to find the hypotenuse, you will have the length of two sides, for example, these could be 3 and 4.

As 'C' is always the hypotenuse, you have to work out the two other lengths, and you do this by squaring the numbers.

3²=9 and 4²=16.

As you're looking for C, you've got to add these together

9+16=25

As a²+b²=c², this means that the answer for C is the square root of 25.

√25= 5

Divide the square in half to make a right triangle. Now, use Pythagoras' theorem to solve for the hypotenuse.

a²+b²=c²

⇒ 36²+36²=c²

⇒ 1296+1296=c²

⇒ 2592=c²

∴ c =50.9116

Round to the nearest whole number, we get c = 51 yards.

Thus, each walkway is around 51 yards long.

A circle is a collection of all points in a plane that are uniformly distanced from a fixed point. The radius of a circle is the difference between the center and any point itself along the perimeter.

A circle is a closed curve that extends outward from a set point known as the center, with each point on the curve being equally spaced from the center. The equation for a circle with a (h, k) center and a radius of r is:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

This is the equation's standard form. So, if we know the radius and center coordinates of a circle, we can rapidly determine its equation.
