H Is The Circumcenter Of Triangle BCD, BC=18, And HD=14. Find CH.

Answers

Answer 1

Given that H is the circumcenter of the triangle.

It means, the length between each vertex point of the triangle and the point H is the radius of the circle.

Thus, the line DH=CH=BH are the radius of the circle.

It is given that DH=14.

Therefore CH=14.

Hence the value of CH is 14.

Answers

Given: A and B are two sets such that-

[tex]\begin{gathered} A\cap B=\phi \\ Pr(A)=0.3 \\ Pr(B)=0.4 \end{gathered}[/tex]

Required: To determine-

[tex]\begin{gathered} Pr(A\cap B) \\ Pr(A\cup B) \end{gathered}[/tex]

Explanation: Since A and B have no common elements, the events are independent events or disjoints or mutually exclusive.

For independent events, we have-

[tex]Pr(A\cap B)=Pr(A).Pr(B)[/tex]

Substituting the values into the formula-

[tex]\begin{gathered} Pr(A\cap B)=0.3\times0.4 \\ =0.12 \end{gathered}[/tex]

Recall that-

[tex]Pr(A\cup B)=Pr(A)+Pr(B)-Pr(A\cap B)[/tex]

Substituting the values into the formula and further solving as-

[tex]\begin{gathered} Pr(A\cup B)=0.3+0.4-0.12 \\ =0.7-0.12 \\ =0.58 \end{gathered}[/tex]

The linear equation has the solution x = 1 only if the value of b is 6

For which value of b is x = 1 a solution?

If we replace x by 1 in that equation, we will get:

2*1 + 14 = 10*1 + b

2 + 14 = 10 + b

16 = 10 + b

To find the value of b such that x = 1 is a solution, we need to isolate b, to do so we need to subtract 10 in both sides.

Consider that you have a population greater than 30, then, you can use the normal distribution to determine the margin of error.

Use the following formula:

[tex]\bar{x}\pm Z_{\frac{\alpha}{2}}\frac{s}{\sqrt[]{n}}[/tex]

where:

x: mean = 33

s: standard deviation = 2

n = 31

Z: z-value for 98%

The value of Z can be found on a table for the normal distribution. For a margin of error at 98%, you get for Z:

Z = 2.326

Replace the previous values of the parameters into the formula for the margin of error (confidence interval):

[tex]\begin{gathered} 33\pm(2.326)\frac{2}{\sqrt[]{31}}= \\ 33\pm0.83 \end{gathered}[/tex]

5) The midrange is 19.5ºF

6) The midrange is 67.5º

Explanation:

The problem tell us how to calculate the midrange.

In (5) the minimum and maximum values are given (-6ºF and 45ºF, respectively). Using the formula:

[tex]Midrange=\frac{-6+45}{2}=\frac{39}{2}=19.5ºF[/tex]

In (6), we need to find the minimum and maximum values from a list of them. We can see that the minimum is 58º and the maximum 77º

Then:

[tex]Midrange=\frac{58+77}{2}=\frac{135}{2}=67.5º[/tex]

In 2009, there were 6.1 million females enrolled in degree granting institutions of higher education. over the next several years this number increased at a rate of 400,000 per year. estimate the number of females enrolled in 2024. y = ______ millionthe equation of the line that models this information is;y = 0.4t + 6.1Determine what year 12.9 million females will be enrolled.

Answers

Notice that

400,000 = 0.4 million

That's why the equation that models that information has the factor 0.4, since it expresses the result in millions of females.

Now, we need to notice that t, in the expression 0.4t + 6.1, is the number of years passed since 2009. So, in the year 2024, we have:

t = 2024 - 2009 = 15

Therefore, the number of females enrolled in 2024 can be estimated to be:

y = (0.4 * 15 + 6.1) million

y = (6 + 6.1) million

y = 12.1 million

Now, to determine the year when 12.9 million females will be enrolled, we first need to find t corresponding to y = 12.9, and then add it to the year 2009.

y = 0.4t + 6.1​

12.9 = 0.4t + 6.1

12.9 - 6.1 = 0.4t

6.8 = 0.4t

t = 6.8/0.4

t = 68/4

t = 17

Therefore, the year when it happens will be:

2009 + 17 = 2026

How do you calculate weekly pay for federal income tax?

An income tax is a charge levied against people or organizations in relation to the income or profits they make. In most cases, income tax is calculated as the sum of the tax rate and the amount of taxable income. The type of taxpayer and the type of income are two factors that can affect the tax rate. Individuals (or family units) and corporations are subject to income taxes. The basis for calculating individual income tax is the income received. Since the burden is presumably on the individuals who pay it, it is typically categorized as a direct tax. Income taxes are assessed against both businesses and people based on their profits. Taxable income can be earned from a variety of sources, including earnings, salaries, dividends, interest, royalties, and rent.

Explanation

Algebra / Graphs and Functions / Equations of Parallel and Perpendicular Lines

We have the line:

[tex]y=7x-1.[/tex]

We must find the equation:

0. of the perpendicular line,

,

1. and the parallel line,

to the given line that passes through the point (-2, 3).

1) Perpendicular line

The equation of the perpendicular line has the form:

[tex]y=m_p\cdot(x-x_0)+y_0.[/tex]

Where mₚ is the slope, and (x₀, y₀) = (-2, 3).

From the equation of the given line, we see that its slope is m = 7. The slope of the perpendicular line mₚ is given by the equation:

[tex]\begin{gathered} m\cdot m_p=-1, \\ 7\cdot m_p=-1, \\ m_p=-\frac{1}{7}. \end{gathered}[/tex]

Replacing mₚ = -1/7 and (x₀, y₀) = (-2, 3) in the equation of the perpendicular line, we get:

[tex]y=-\frac{1}{7}\cdot(x-(-2))+3=-\frac{1}{7}\cdot(x+2)+3=-\frac{1}{7}\cdot x-\frac{2}{7}+3=-\frac{1}{7}\cdot x+\frac{19}{7}.[/tex]

2) Parallel line

The equation of the perpendicular line has the form:

[tex]y=m_p\cdot(x-x_0)+y_0.[/tex]

Where mₚ is the slope, and (x₀, y₀) = (-2, 3).

From the equation of the given line, we see that its slope is m = 7. The parallel line has the same slope as the given line, so we have:

[tex]\begin{gathered} m_p=m, \\ m_p=7. \end{gathered}[/tex]

Replacing mₚ = 7 and (x₀, y₀) = (-2, 3) in the equation of the parallel line, we get:

[tex]y=7\cdot(x-(-2))+3=7\cdot(x+2)+3=7x+14+3=7x+17.[/tex]

3) Graph

Plotting the equations obtained, we get the following graph:

Step 1: The term -2(x-2)² is simplified by first squaring the expression x-2.

[tex]\begin{gathered} 3x(x-12x)+3x^2-2(x-2)^2 \\ =3x(x-12x)+3x^2-2(x-2)(x-2) \\ =3x(x-12x)+3x^2-2(x^2-2x-2x+4) \\ =3x(x-12x)+3x^2-2(x^2-4x+4) \end{gathered}[/tex]

Step 3: After multiplying, the like terms are combined by adding and subtracting.
