The congruent angles of an isosceles right triangle measure is 45° each.

How big should the angles be in an isosceles right triangle?Properties of an Isosceles Right TriangleOne of its angles is 90 degrees. The base and height of this triangle are the perpendicular legs, which are also referred to as the base and height. In an isosceles right triangle, the other two angles are sharp, congruent, and measure 45 degrees each.Due to the equality of the two sides, the corresponding angle is congruent. As a result, two sides of an isosceles right triangle are congruent, and the associated angles are each 45 degrees, adding up to 90 degrees. The triangle's three angles will thus add up to 180 degrees.

How are position vs time graph useful ?

Answers

An object's distance from its beginning point during the course of its motion is displayed as a position-time graph. A line's slope increases with its steepness, and an object's motion changes more quickly as a result.

How would you explain a time graph?We can see how the speed of a moving object varies over time by looking at a speed-time graph. The acceleration is larger the steeper the graph is. The object is moving steadily if there is a horizontal line. An object is said to be slowing down when a line dips downward.The vertical axis (y-axis) of a distance-time graph will display the distance (in meters, kilometers, miles, etc.) and the horizontal axis will display the time (in seconds, minutes, hours, etc).

Answers

V is at its maximum when [tex]a = b\ \pi x[/tex],  [tex]V = \pi x2h[/tex], and [tex]c = a x2 + b\ \pi xh[/tex].

Determine the cost of the tank.

This question uses the principles of geometry, specifically the formulas for the area of a circle and the area of a curved surface. In addition, the concept of cost maximization is used to determine the cost of the tank when the volume is at its maximum.

Given,

[tex]c = a x2 + b\ \pi xh[/tex]

This equation states that the cost of the tank is equal to the cost of the base plus the cost of the curved surface.

The cost of the base is equal to the area of the base multiplied by the cost per square metre, which is a.

The area of the base is equal to [tex]\pi x2[/tex], where x is the radius of the base. The cost of the curved surface is equal to the area of the curved surface multiplied by the cost per square metre, which is b.

The area of the curved surface is equal to πxh, where h is the height of the tank.

Combining these two equations gives the equation for c.

[tex]V = \pi x2h[/tex]

This equation states that the volume of the tank is equal to the area of the base multiplied by the height.

The area of the base is equal to [tex]\pi x2[/tex], where x is the radius of the base. The height of the tank is h. Combining these two equations gives the equation for V.

V is at its maximum when [tex]a = b\pi x[/tex]

This equation states that the volume of the tank is maximized when the cost of the base is equal to the cost of the curved surface.

The cost of the base is equal to the area of the base multiplied by the cost per square metre, which is a.

The area of the base is equal to [tex]\pi x2[/tex], where x is the radius of the base. The cost of the curved surface is equal to the area of the curved surface multiplied by the cost per square metre, which is b.

The area of the curved surface is equal to πxh, where h is the height of the tank.

Setting a equal to bπx gives the equation for the maximum volume.

E(aX + b) = aE(X) + b, which shows that E(ax + b) = aE(X) + b, as stated.

What is integration ?

An integral assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinitesimal data. The process of finding integrals is called integration.

This statement can be shown using the linearity property of expectation. According to this property, if X is a random variable and a, b are constants, then E(aX + b) = aE(X) + b.

Applying this property, we have:

E(aX + b) = aE(X) + b

= a(E(X) + b/a)

= aE(X) + ab/a

= aE(X) + b

(b) sketch lines through (0, 0) with slopes 1 4 , 1 2 , − 1 4 , and 4.

Answers

Sketch lines through (0, 0) with slopes of 1 4, 1 2, 1 4, and 4 through the line with slope 4: y - 0 = 4 (x - 0), which reduces to y = 4x.

What do you mean by slope?

The slope of a line is a measure of its steepness or incline and is defined as the ratio of the rise (the vertical change) to the run (the horizontal change) between two points on the line. Slope is commonly represented as "m" in the equation of a line, y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).

The slope of a line can be calculated by dividing the difference in y-coordinates (rise) by the difference in x-coordinates (run) between two points on the line. If (x1, y1) and (x2, y2) are two points on the line, the slope is calculated as:

m = (y2 - y1) / (x2 - x1)

(b) To sketch the lines through (0,0) with slopes 1/4, 1/2, -1/4, and 4, we can use the point-slope form of a line: y - y1 = m(x - x1), where m is the slope of the line and (x1, y1) is a point on the line. For each line, we can substitute the given slope and the point (0,0) to find the equation of the line:

Line with slope 1/4: y - 0 = 1/4 (x - 0), which simplifies to y = 1/4x

Line with slope 1/2: y - 0 = 1/2 (x - 0), which simplifies to y = 1/2x

Line with slope -1/4: y - 0 = -1/4 (x - 0), which simplifies to y = -1/4x

Discussion topic

Answers

Both analytical and Euclidean geometry have strengths and applications, and which technique to choose depends on the individual problem or job at hand.

Analytical geometry, often known as coordinate geometry, represents and analyses geometric objects using mathematical ideas such as algebra and calculus. It is especially useful for analysing objects with a distinct numerical representation, such as lines, circles, and conic sections. Analytical geometry, which provides a systematic framework for modelling and analysing things in any number of dimensions, may readily be extended beyond two dimensions.

Euclidean geometry, on the other hand, studies geometric objects such as points, lines, and planes using a set of axioms and definitions. This method is very beneficial for learning geometric concepts like congruence, similarity, and structures. Euclidean geometry is also beneficial for problem solving that necessitates visualisation, intuition, and spatial reasoning.

Analytical geometry is more helpful in real-world applications such as computer graphics, where objects are represented using mathematical equations and algorithms. Euclidean geometry, on the other hand, is more beneficial in fields like architecture and engineering, where a greater knowledge of geometric principles and spatial reasoning is necessary.

I need to know how long my shadow would be

Answers

Your height and the length of your shadow are related by the formula 1/Tangent (height of the sun). Your shadow would be 5.67 times longer than you if the sun were to be at its lowest point in the sky (10 degrees). At 5 degrees, the proportion is 11.43. (A person of average height (5.8 feet) would therefore cast a shadow that is 66 feet long.)

How would one describe a shadow's length?

The length of the shadow is influenced by the Sun's position in the sky. The shadows are long when the Sun is low in the horizon. The shadows are substantially shorter when the Sun is high in the sky.

How far does your morning shadow extend?

Because the sun's rays are slanted in the morning and evening but are directly overhead at noon, the shadows are longer in the morning and evening and shorter in the noon. The distance of the object from the light source affects how big the shadow is.

To do this, we will add x to both sides of the equation to cancel out the subtraction of x on the left-hand side. The equation becomes

=> x³ = x + 80.

Next, we will take the cube root of both sides to isolate x on one side of the equation. The cube root of x³ is just x, so we get

[tex]x = x^{1/3} + 80^{1/3}[/tex]

Now, we have a simple equation in x and can use basic algebraic techniques to solve for x.

a research study randomly assigned participants into two groups. one group was given vitamin e to take daily. the other group received only a placebo pill. the research study followed the participants for eight years. after the eight years, the proportion of each group that developed a particular type of cancer was compared. what is the primary reason that the study used random assignment?

Answers

The primary reason for the use of random assignment in the research study was to ensure that participants in each group were similar to each other in terms of relevant factors, such as age, gender, or health status.

By randomly assigning participants into two groups, the researchers could ensure that any difference observed between the two groups was due to the intervention and not due to any other factor.

Random assignment eliminates the possibility of bias being introduced into the study, as the two groups are as similar as possible.

This means that any observed difference between the two groups can be attributed directly to the intervention, in this case, the vitamin E supplement.

By randomly assigning participants, the researchers could be sure that the results of the study were valid and could be relied upon.

Find the diagonal of a square whose sides are of the given measure.

Given = 7√3

Answers

Step-by-step explanation:

Use the Pythagorean theorem: a^2 + b^2 = c^2. In this case, sides a and b are each 7sqrt(3), and c is the diagonal of the square.

a^2 + b^2 = c^2

(7sqrt3)^2 + (7sqrt3)^2 = c^2

294 = c^2

c = sqrt(294) = 7sqrt(6)

Due to the difference in the number of columns in A and B, the operation B+A is not defined. ACC - This operation cannot be defined because A's number of columns and C's number of rows are not equal.

What do you mean by matrix?

A matrix is a row-and-column-organized rectangular array containing numbers, symbols, or expressions. In mathematics, science, and engineering, matrices are frequently used to represent and manipulate data as well as to resolve linear equation systems.

The following are defined given that A, B, and C are all 8 by 9 matrices:

A. B+A - This operation is not described because A and B have different numbers of columns.

B. ACC - This operation is undefinable since A's number of columns and C's number of rows are not equal.

C. C-B - This operation is not described because C has more rows than B does because B has more columns.

D. Assuming B is a matrix with a diagonal of 9, this operation is defined and produces a matrix with a diagonal of 3.

E. AB - This operation is known as AB if A's number of columns and B's number of rows are equal. The outcome is an 8 by 9 matrix.

F. CB - If the number of columns is 1, then this operation is defined.

cse 4310 – worksheet3 graph algorithms 1. (50 pts) [graph traversal and representation] for the following graph: a. (10 pts) write down the adjacency list representation

Answers

By "graph representation," we only mean the process of storing a particular graph in a computer's memory.

An adjacency matrix is used in sequential representation to show how the graph's vertices and edges map to one another. The undirected graph, directed graph, weighted directed graph, and weighted undirected graph may all be represented using an adjacency matrix.

Edges in a directed graph represent a particular route between two vertex locations. If a path connects vertex A to vertex B, then vertex A serves as the starting point and vertex B serves as the ending point.

It is similar to an adjacency matrix representation of a directed graph except that instead of using the '1' for the existence of a path, here we have to use the weight associated with the edge.

Correct question: What is graph traversal and representation for the graph? write down the adjacency list representation.

on any given day, a child is either healthy or sick. of children who are healthy today 95% will be healthy tomorrow. of the children who are ill today, 55% will still be ill tomorrow. if 20% of children are ill, what fraction of the children are likely to be ill in two days?

Answers

3% of children are likely to be ill in two days.

Let's call the fraction of children who are ill today x.

The fraction of children who are healthy today is (1 - x).

The fraction of children who were healthy today and will be healthy tomorrow is (1 - x) * 0.95.

The fraction of children who were ill today and will still be ill tomorrow is x * 0.55.

The fraction of children who will be ill in two days is x * 0.55 + (1 - x) * 0.05 = 0.55x + 0.05 - 0.95x = -0.4x + 0.05.

So, if 20% of children are ill today, then x = 0.2, and the fraction of children who are likely to be ill in two days is -0.4 * 0.2 + 0.05 = 0.03.

Therefore, 3% of children are likely to be ill in two days.

Answers

b = 2 does not make the equation true

What is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.

15 = 5b

when b=2,

15=5(2)

15 = 10

This is not true

So, b = 2 does not make the equation true

choose the function and interval for which the mean value theorem does not apply.

Answers

The mean value theorem does not apply to functions that are not continuous on a closed interval [a, b], or not differentiable on an open interval (a, b).

The mean value theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists a point c in the interval (a, b) such that:

f'(c) = (f(b) - f(a)) / (b - a)

For example, the function f(x) = |x| is continuous everywhere, but it is not differentiable at x = 0. The interval [0, 1] does not satisfy the conditions for the mean value theorem to apply.

So, a possible function and interval for which the mean value theorem does not apply is f(x) = |x| on the interval [0, 1].
