The length of the altitude of the equilateral triangle ABC is \(\frac{13\sqrt{3} }{2}\).

Equilateral Triangle is defined as the triangle with all the sides equal and all the angles = 60 deg.

Altitude of a Triangle can be defined as the perpendicular drawn from the vertex of a triangle to the opposite side.

According to the question

In the figure given below

In ΔADC

Since ΔADC is a right angle triangle we can apply Pythagoras Theorem.

Let the sides of the equilateral triangle be "a". and "h" be the altitude.

Since the altitude is of equilateral triangle it divides the base i.e. DC=a/2

\((AC)^{2} =(AD)^{2}+(DC)^{2}\)

\(a^{2} =h^{2}+(\frac{a}{2})^{2}\\ \\ h^{2}=\frac{4a^{2}-a^{2}}{4} \\ \\ h=\sqrt{3} *\frac{1}{2} *a\)

Substituting the value of a=13 we get

Altitude \(h=\frac{13\sqrt{3} }{2}\)

Therefore , The length of the altitude of the equilateral ΔABC is \(\frac{13\sqrt{3} }{2}\).

Answer:

\(\displaystyle{P(x)=x^3-x^2}\)

Step-by-step explanation:

Given the zeros of 0, 0, 1. We can write the polynomial in form of x-intersects:

\(\displaystyle{P(x) = (x-x_1)(x-x_2)(x-x_3)}\)

Hence:

\(\displaystyle{P(x)=(x-0)(x-0)(x-1)}\)

Which can be simplified to:

\(\displaystyle{P(x)=x\cdot x \cdot (x-1)}\\\\\displaystyle{P(x)=x^2(x-1)}\)

Convert to the standard form by distributing x²:

\(\displaystyle{P(x)=x^2\cdot x - x^2 \cdot 1}\\\\\displaystyle{P(x)=x^3-x^2}\)

Based on the given information that Caruso, Inc. has an inventory turnover rate of 8 times and a cost of goods sold of $150,000, the company average inventory can be calculated.

To calculate the average inventory, we can use the formula: Average Inventory = Cost of Goods Sold / Inventory Turnover Rate.

Plugging in the values, we have: Average Inventory = $150,000 / 8 = $18,750. Therefore, option c. The company's average inventory is $18,750 is the correct answer.

The inventory turnover rate measures how quickly a company sells its inventory during a specific period. In this case, the turnover rate of 8 times indicates that Caruso, Inc. sells its entire inventory 8 times per year. This suggests that the company has an efficient inventory management system and a relatively high sales volume compared to its inventory level.

If a ray of light is traveling at a downward angle of 45 degrees and strikes an object, the ray will reflect back at the same angle from the object.

The law of reflection say that when light fall on an object that is able to reflect the ray of light than the light will be reflected from the normal to the surface at the same angle at which the ray has fallen on to the surface.

So, when a light beam strikes an item while approaching it at a 45-degree downward angle, the beam will return at the same angle.

The angle will be measured from the surface of the object or the normal. Although it does not matter in this particular case because the angle will be same in this case measured from anywhere, the normal or the surface of the object.

Answer:

45 degrees

Step-by-step explanation:

The side that is opposite the 95-degree angle should be the longest, followed by the 53-degree angle and finally the 32-degree angle, which will be the shortest. The answer is (b).

How do you tell which angle is larger: The largest angle is located across from the longest side, just like with the sides. Theorem: If and only if angle A (= angle CAB) is greater than angle B (= angle ABC), then side BC of a triangle ABC will be longer than side CA. To put it another way, larger sides are in opposition to larger angles.

If you have an angle and its opposite side, you may calculate the hypotenuse by dividing the length of the opposing side by sin(). To find the length of the side next to the angle, you can also divide the length by tan(). Less than 90 degrees is the acute angle measurement. Right angles are 90 degrees in length. Angles that are obtuse are more than 90 degrees. Hint: There are two fundamental units used to measure angles from one of the two fundamental units, radians () or degrees ().

Correct Question:

The required perimeter of the door on the scale drawing is 4 cm, which is option A.

Perimeter is the measure of the figure on its circumference.

Here,
To find the perimeter of the door on the scale drawing, we need to first find the dimensions of the door on the scale drawing. We can use the scale 2:8 to convert the actual dimensions of the door to the corresponding dimensions on the scale drawing:

Height on scale drawing = (2/8) x 5 cm = 1.25 cm

Width on scale drawing = (2/8) x 3 cm = 0.75 cm

The perimeter on the scale drawing = 2 x (height on scale drawing + width on scale drawing)

Perimeter on scale drawing = 2 x (1.25 cm + 0.75 cm)

Perimeter on scale drawing = 2 x 2 cm

The perimeter on the scale drawing = 4 cm

(a) To prove An(BUC) = (AUB) n (AUC), we show that any element x in An(BUC) belongs to (AUB) n (AUC) by considering two cases: when x belongs to B and when x belongs to C.

(b) To demonstrate (A - B) n (B - A) = 0, we assume the existence of an element x in both (A - B) and (B - A), leading to a contradiction. Therefore, the intersection of the two sets is empty.

(a) To prove An(BUC) = (AUB) n (AUC), we need to show that any element x belongs to both sides of the equation.

Let's start with the left-hand side, An(BUC). This means x belongs to both A and BUC. Since x is in BUC, it must either be in B or in C. Therefore, we have two cases:

Case 1: x belongs to B

In this case, x is in both A and B, so it belongs to AUB. Also, since x is in C (from BUC), it belongs to AUC. Therefore, x belongs to both AUB and AUC, which implies that x is in (AUB) n (AUC).

Case 2: x belongs to C

Similar to Case 1, x is in both A and C, so it belongs to AUC. Also, since x is in BUC, it belongs to B as well. Therefore, x belongs to both AUC and AUB, implying that x is in (AUB) n (AUC).

In both cases, we have shown that any element x in An(BUC) also belongs to (AUB) n (AUC). Hence, we have proved that An(BUC) = (AUB) n (AUC).

(b) To prove (A - B) n (B - A) = 0, we need to show that the intersection of the two sets is empty, meaning there are no common elements.

Let's assume there exists an element x that belongs to both (A - B) and (B - A). This implies that x belongs to A but not to B, and at the same time, x belongs to B but not to A. However, this leads to a contradiction since an element cannot simultaneously belong to a set and not belong to the same set.

Hence, our assumption that there exists an element x belonging to both (A - B) and (B - A) is false. Therefore, the intersection of the two sets is empty, and we can conclude that (A - B) n (B - A) = 0.

The equation 3x = 7 in Z₁1 has a unique solution. : True

The given equation is 3x = 7 in Z₁1, and we are asked to determine if it has a unique solution or not. In Z₁1, there are only two elements, 0 and 1.

To solve the given equation, we can try both the elements of Z₁1 and see which one satisfies the equation. Putting

x = 0, we get 3 × 0 = 0, which is not equal to 7.

Putting x = 1, we get 3 × 1 = 3, which is not equal to 7. Hence, there is no solution for the given equation in Z₁1.

Therefore, the statement "The equation 3x = 7 in Z₁1 has a unique solution" is false.The equation 2x = 7 in Z₁0 has a unique solution.

False The given equation is 2x = 7 in Z₁0, and we are asked to determine if it has a unique solution or not. In Z₁0, there is only one element, 0.

To solve the given equation, we can try x = 0. But 2 × 0 is not equal to 7. Hence, there is no solution for the given equation in Z₁0.

Therefore, the statement "The equation 2x = 7 in Z₁0 has a unique solution" is false.

Step-by-step explanation:

To solve for the volume of a right circular cone like the one in the picture, you use \(\pi\)\(r^{2}\)\(\frac{h}{3}\).

Plug in the radius and height to get \(\pi\)\(20^{2}\)\(\frac{20}{3}\).

Then solve (and round to the nearest hundredth) and you should get 8,377.58.

In the fixed-point iteration, choosing a suitable g(x) is a crucial step that determines the rate and convergence of the method.

The results obtained from Tables in Steps 3 and 4 provide an insight into how the choice of g(x) affects the convergence of the fixed-point method.

When discussing how the choice of g(x) affects the convergence of the fixed-point method, it is essential to note that g(x) is a continuous function in the interval [a,b], and its fixed point, say α, is also in the interval [a,b].

The table in step 3 provides a comparison of the absolute error of fixed-point iteration for three different choices of g(x) (i.e., g1(x), g2(x), and g3(x)).

It shows that as the number of iterations increases, the absolute error reduces for all three cases.

However, the rate of convergence for each choice of g(x) is different. g2(x) converges faster than g1(x) and g3(x). This indicates that the choice of g(x) affects the speed of convergence.

The table in step 4 compares the actual number of iterations required for the three choices of g(x) to obtain the root. It shows that the choice of g(x) affects the number of iterations required to obtain the root.

For instance, g2(x) requires fewer iterations to converge than g1(x) and g3(x). This implies that the choice of g(x) affects the efficiency of the method.

In conclusion, the choice of g(x) has a significant impact on the convergence and efficiency of the fixed-point iteration method. The right choice of g(x) results in faster convergence and fewer iterations required to obtain the root.

A normally distributed phenomenon using standard nomenclature can be described as follows:

A dataset is said to be normally distributed if it follows a bell-shaped curve, which is symmetrical around the mean (µ) and characterized by its standard deviation (σ). In standard nomenclature, a normally distributed dataset is represented as \(N(µ, σ^2)\), where µ is the mean and \(σ^2\)is the variance (square of the standard deviation).

For example, if we consider the heights of adult males in a large population, we may observe that the distribution is normally distributed with a mean height (µ) of 175 cm and a standard deviation (σ) of 10 cm.
