Answer:

Step-by-step explanation:

Use the formula for circles.

\(x^{2} + y^{2} = r^{2}\)

Since we already have the values of x and y in the given problem (-2,3), substitute the values in the fomula.

\(x^{2} + y^{2} = r^{2}\)

\((-2)^{2} + (3)^{2} = r^{2}\)

\(4 + 9 = r^{2}\)

\(13 = r^{2}\) (square both sides to get the radius)

\(\sqrt{13} = \sqrt{r^{2} }\)

\(\sqrt{13} = r\)

Answer:

x-intercept: -(\(\frac{35}{9}\),0)

y-intercept: (0,-3)

Step-by-step explanation:

Using the symmetry property of the graph of y = f(x) with respect to the line x = -3, we can find another value for the function. Since f(-1) = -2, the corresponding point on the other side of the line x = -3 is (-5, -2), implying that f(-5) = -2.

Given that the graph of y = f(x) is symmetric with respect to the line x = -3, we know that if a point (a, b) lies on the graph, then the point (-6 - a, b) also lies on the graph. This symmetry property allows us to find another value for the function.

Given that f(-1) = -2, we can determine the corresponding point on the other side of the line x = -3 by mirroring the given point. The x-coordinate of the mirrored point is obtained by subtracting the x-coordinate of the given point from -6. In this case, -6 - (-1) = -5. So, the mirrored point is (-5, -2), and we can conclude that f(-5) = -2.

In conclusion, by utilizing the symmetry property of the graph with respect to the line x = -3, we find that f(-5) = -2.

Therefore , the solution to the given problem of the equation comes out be  y-intercept of g(x) is (0,15).

An equation is referred to as linear when all of the highest powers of the variables are equal to one. The components are interconnected. This kind of issue is also known as a one-degree equation. Learn how to solve a linear equation in one or two variables using the standard form, formula, graph, and instructions in the following paragraphs.

Here,

1) The quadratic factored form can be written as follows because the g(x) function has the x-intercepts "5" and "-1":

y equals a(x-x1)(x-x2), y equals a(x-5)(x+1).

2) We may rewrite the "a" coefficient as follows since we were informed that this g(x) function has been extended vertically by a factor of 3 and mirrored over the x-axis:

g(x) = -3(x-5)(x+1)

3) In order to obtain the function and the y-intercept, let's extend that.

g(x) = -3(x-5)(x+1)

g(x) = -3\(x^{2}\) + 12x + 15

It's important to note that the leading coefficient's minus sign indicates that, in comparison to the parent function, the equation has been stretched vertically and reflected.

Thus, the y-intercept of g(x) is (0,15)

Standard Normal Distribution is also known as the Z-distribution. It is a normal distribution with a mean of 0 and a standard deviation of 1. We use the standard normal distribution to convert any normal distribution to the standard form. In standard form, we can get probabilities of different random variables from the standard normal distribution.

Let Z be a standard normal random variable and we need to find its value if the area to the right of Z is 0.1401. Therefore, the value of Z is 1.08.  Here's the solution:Given that Z is a standard normal random variable.The area to the right of Z is 0.1401.We know that the total area under the normal distribution curve is 1. Let's draw the standard normal distribution curve. We need to find the value of Z such that the area to the right of Z is 0.1401. The area shaded below represents 0.1401. Let Z = z0.1401 represents the value of Z corresponding to an area of 0.1401.

Since the total area is 1, the area to the left of z0.1401 is 1-0.1401 = 0.8599.Now, look up the table of standard normal distribution.  Look for the area 0.8599 in the standard normal distribution table. We can use the standard normal distribution table to find the values of the area under the standard normal curve for different values of Z.The corresponding value of Z is 1.08.Therefore, the value of Z if the area to the right of Z is 0.1401 is 1.08.

The value of x in the given triangle is 2.44 units.

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.

Similar figures are described as items with the same shape but varying sizes, such as two or more figures. While both have the same form, the sizes may vary. Each pair of comparable angles are equal. Similar equivalent side ratios exist.

Given that, LM bisects angle JLK.

Thus, angle JLM = angle MLK.

The two triangles triangle JKL and triangle MLK are similar using AA criteria.

Since, the two triangles are equal the ratio of their sides are equal.

Using Pythagoras theorem in triangle MLK we have:

LM² = 4² + 8²

LM = 8.9

Now, using the ratio:

x + 3 / 8.9 = x / 4

4x + 12 = 8.9x

12 = 4.9x

x = 2.44

Hence, the value of x in the given triangle is 2.44 units.

The factor that does NOT control the stability of a slope is the angle of repose for intact bedrock. The angle of repose refers to the steepest angle at which a pile of loose material remains stable without sliding. It is mainly applicable to loose materials like soil and granular substances, not intact bedrock.

Bedrock stability depends on factors such as its strength, fracturing, and geological properties, rather than the angle of repose. Factors that control the stability of a slope include whether the slope is rock or soil. Rock slopes tend to be more stable than soil slopes due to the cohesive nature of intact rock.

The amount of water in the soil also affects slope stability, as excessive water can increase pore pressure and reduce the shear strength of the soil, leading to slope failure. Additionally, the orientation of fractures, cleavage, and bedding in the rock can influence slope stability by creating planes of weakness or strength.

To summarize, while the angle of repose is a significant factor in slope stability, it is not applicable to intact bedrock. The stability of a slope is influenced by the type of material (rock or soil), the presence of water, and the orientation of fractures and bedding.

The statement \(\cos 35^\circ \cos 35^\circ + \sin 35^\circ \sin 35^\circ = 1\) is true.

The statement \(\cos 35^\circ \cos 35^\circ + \sin 35^\circ \sin 35^\circ = 1\) is true, and we can demonstrate this by using the Pythagorean identity.

The Pythagorean identity states that for any angle \(\theta\), the sum of the squares of the cosine and sine of that angle is equal to 1: \(\cos^2 \theta + \sin^2 \theta = 1\).

In this case, we have \(\theta = 35^\circ\). Substituting this into the Pythagorean identity, we get:

\(\cos^2 35^\circ + \sin^2 35^\circ = 1\).

Now, we can simplify the left-hand side of the equation using the properties of trigonometric functions. Since \(\cos\) and \(\sin\) are both functions of the same angle, 35 degrees, we can express them as \(\cos 35^\circ\) and \(\sin 35^\circ\) respectively.

So, the original expression \(\cos 35^\circ \cos 35^\circ + \sin 35^\circ \sin 35^\circ\) can be rewritten as \(\cos^2 35^\circ + \sin^2 35^\circ\).

Since the left-hand side and the right-hand side of the equation are now identical, we can conclude that the statement is true: \(\cos 35^\circ \cos 35^\circ + \sin 35^\circ \sin 35^\circ = 1\).

This verifies that the given trigonometric expression satisfies the Pythagorean identity, which is a fundamental relationship in trigonometry.

The average of the points A, B and C with weights 1, 1 and 1

respectively is: (-5/3, -2)

A technique known as a weighted average accounts for the varied levels of significance of the values in a data collection. Each number in the data set is multiplied by a predefined weight before the final computation is completed when calculating a weighted average.

Thus:

Weighted average = [(w₁ × x₁) + (w₂ × x₂) + (w₃ × x₃)]/(w₁ + w₂ + w₃)
