This is an example of a triangle with two missing sides.
TrigonometryTo find the missing sides of a triangle, you can use the trigonometric ratios of sine, cosine, and tangent. All of these are based on the reference angle, which is the angle between the two known sides.For example, if the reference angle is 30°, then the trigonometric ratios are: sine of 30° is 1/2, cosine of 30° is √3/2, and tangent of 30° is √3/3.To find the missing sides of a triangle, you can use the Law of Sines and Law of Cosines. The Law of Sines states that the ratio of the lengths of the sides of a triangle to the sines of their opposite angles is the same for all three sides. The Law of Cosines states that the sum of the squares of the two sides of a triangle is equal to the square of the third side minus twice the product of the two sides multiplied by the cosine of the angle between them.Using these two laws, you can solve for the missing sides of the triangle. For example, if you know the length of two sides and the angle between them, you can use the Law of Cosines to find the length of the third side. Then, you can use the Law of Sines to find the angles of the other two sides. This method of finding the missing sides of a triangle is called trigonometry.To learn more about trigonometry refer to:

The percentage change in the Touchdown passes is 28 %
What is percentage ?A figure or ratio stated as a fraction of 100 is called a percentage. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.
Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. A percentage can be found in one of two ways:
use the unitary approach.by adjusting the fraction's denominator to 100.It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation is not applied. In these situations, we employ the unitary technique.

Inside a square with side length 10, two congruent equilateral triangles are drawn such that they share one side and each has one vertex on a vertex of the square. What is the side length of the largest square that can be inscribed in the space inside the square and outside of the triangles
Therefore ,2.113 is the deemed appropriate of the greatest square that could be inscribed with in area between the square and the triangle.
Describe the triangle.A triangle is considered a polygon since it has four vertices or segments. It is a basic geometric form. Triangle ABC refers to a triangle the with ends A, B, and C. In Euclidean geometry, a singular plane plus square are produced when the sides are not collinear. A triangle is a polygon if it has three parts and three corners. The points where the three sides of the triangle meet are known as its corners. Three triangle angles add up to 180 degrees.
Here,
The midpoint of foot FE, G, is where we start by measuring the side length of the equilateral triangle.
Given that DE=GB and G is the midpoint, let GE equal x.
As a result, DGGB=x3 using fundamental trigonometry.
DB=2x3 follows.
We may then construct the equation 2x3=102 because DB is the orthogonal of ABCD and has length 102. Thus, the triangle's side length is
2x=(10√2)/√3.
Now, observe the diagonal AC. It is composed of the triangle's side length and the little square's diagonal multiplied by two. Let the little square's side length be y:
Let the little square's side length be y:
AC=y√2 + [(10√2)/√3]+y√2=10√2.
How to find y?
=>y√2+y√2 + (10√2√3)/3=10√2
=>y√2+y√2 + (10√6)/3=10√2
=> [3y√2+3y√2 + (10√6)] /3=10√2
=>6y√2+10√6=30√2
=>6y√2 = 30√2-10√6
=>y√2 = (30√2-10√6)/6
=>y = (30√2-10√6)/6√2
=>y = (60-20√3)/12
=>y= 5(3−√3)3 or 2.113

On solving the provided question we cans ay that the upper bound for the integral is 1/(n+1).
what is integral?In mathematics, integrals translate integers into functions that express concepts like displacement, area, and volume that result from the combination of little facts. Integral discovery is a process that is referred to as integration. Integrals are mathematical constructs that, in calculus, have the same meaning as areas or generalized versions of areas. The main goal of calculus is to work with derivatives and integrals. Primitives and inverse derivatives are other terms for integral. Integration is essentially utilized to determine the area of 2D space and determine the volume of 3D objects. As a result, calculating an integral of a function with respect to x entails calculating the area between the curve and the x-axis.
The maximum value of the integrand on the interval [0, 1] is:
f(x) = 5x(1 + x)^(0.5)
At x = 1, f(x) = 5(1 + 1)^(0.5) = 5√2.
Therefore, an upper bound for the integral is:
In ≤ 5√2∫x^n dx
Using integration by parts, we obtain:
In ≤ 5√2[x^(n + 1)/(n + 1)]_0^1
= 5√2/ (n + 1)
Therefore, the upper bound for the integral is 1/(n+1).

Cox Proportional hazards Model:
Sir David Cox observed that if the proportional hazards assumption holds (or, is assumed to hold) then it is possible to estimate the effect parameter (s), denoted β₁ below, without any consideration of the full hazard function. This approach to survival data is called application of the Cox proportional hazards model, sometimes abbreviated to Cox model or to proportional hazards model. However, Cox also noted that biological interpretation of the proportional hazards assumption can be quite tricky.
Let Xi = ([tex]X_i1[/tex] , … , [tex]X_in[/tex]) be the realized values of the covariates for subject i. The hazard function for the Cox proportional hazards model has the form:
λ (t I [tex]X_i[/tex]) = λ₀(t) exp( β₁[tex]X_i1[/tex] +...... + βₙ[tex]X_in[/tex])
= λ₀ (t) exp( [tex]X_i . \beta[/tex])
This expression gives the hazard function at time t for subject i with covariate vector (explanatory variables) Xi. Note : that between subjects, the baseline hazard is identical (has no dependency on i). The only difference between subjects' hazards comes from the baseline scaling factor exp [tex](X_i . \beta)[/tex].

How does the us tax policy encourage long-term investments?

d. by providing a lower tax rate for long-term gains
The US tax policy encourage long-term investments by providing a lower tax rate for long-term gains.
Therefore the answer is d. by providing a lower tax rate for long-term gains.
In the United States, the tax code provides a lower tax rate for long-term capital gains, which are gains on investments held for more than one year, as a way to encourage long-term investments. This means that when an investor sells an asset that they have held for more than one year, they will pay a lower tax rate on the gain than they would if they had held the asset for less than one year. This provides an incentive for investors to hold on to their investments for a longer period of time, rather than engaging in short-term buying and selling.

Josh graphs a system of equations to determine the roots of the polynomial equation x⁵ = -2x² . From the graph, he determines that there are two solutions to the equation. Which statement is true?
He is correct because the least exponent of the system is two so there must be two solutions.He is not correct because the greatest exponent of the system is five so there must be five solutions, three of which must be multiplicities or complex.He is correct because the graph shows two intersection points.He is not correct because the difference of the exponents is three, so there must be three solutions, one of which is a multiplicity.Pls help with theseeeeeeee
Yes, you can assume both statements. In the diagram, planes W and X intersect at the line KL.
Determine whether you can assume the statement?This means that the points K, L, M, and N lie on the same plane, making them coplanar.All four points are contained within the same plane and are connected by lines, so it is clear that they all lie on the same plane.This means that statement 11 is true and statement 12 is also true.Yes, you can assume the statement in Exercises 11 and 12.The statement in Exercise 11 is true because it is shown in the diagram that Planes W and X intersect at KL.The statement in Exercise 12 is true because the points K, L, M, and N all lie on the same plane, which is Plane W.This type of reasoning is called deductive reasoning.Deductive reasoning is a logical process in which a conclusion is drawn based on the evidence that is given.In this case, the evidence is the diagram and the conclusion is the statement in the exercise.

What is stem-and-leaf plot?A stem and leaf plot, often known as a stem plot, is a method for categorizing discrete or continuous data. Data are organized as they are gathered using a stem and leaf plot. A stem and leaf plot resembles a bar graph in appearance. As each integer throughout the database is divided into a stem and a leaf, thus the name fits.
The last digit of each data point serves as the "leaf" in a stem and leaf plot, which divides the data into numerical points (the leading digit or digits).
Thus, in this case, correct option is:b
in a stem-and-leaf display: b. one or more digits are used to define each stem, and a single digit is used to define each leaf

The volume of a cylinder is 90 cm³. If the radius is 3 cm, what is the height of the cylinder? OA. 10 cm OB. 30 cm C. 15 cm D. 5 cm 3 cm
Answer:
3 cm
Step-by-step explanation:
Volume of a cylinderThe formula of a cylinder is given by:
[tex]\pi r^{2} h[/tex]
where r is the radius and h is the height of the cylinder.
SolutionGiven information from the question:
Volume of cylinder = [tex]90cm^{3}[/tex]
Radius of cylinder = 3cm
We can derive an equation to find the height:
[tex]90=\pi 3^{2} h\\9\pi h=90\\h = \frac{90}{9\pi } \\h = 3.18cm[/tex]
Given the height is 3.18cm, we will choose the closest answer which is 3 cm.
