How to find the angles of an isosceles triangle?

An isosceles triangle is a triangle that has two sides equal to each other and two angles congruent to each other.

The base angles of an isosceles triangles are congruent and the two legs are also equal.

Therefore, ΔHIJ

where

HI ≅ IJ

m∠H  = 3x + 10

m∠I = 6x - 20

Therefore,

m∠H ≅ m∠J

m∠H  + m∠I+ m∠J = 180

3x + 10 + 6x - 20 + 3x + 10 = 180

12x  = 180

x = 180 / 12

x = 15

Hence,

m∠H  = 3(15) + 10 = 55 degrees

m∠I = 6(15) - 20 = 90 - 20  = 70 degrees

m∠J = 55 degrees.

6x-3y= -21

Help

Answers

Answer:

The answer is x = -6 and y = -5.

Step-by-step explanation:

To solve this problem, we can use substitution. Let's first solve one of the equations in terms of the variable y, and then substitute this value into the other equation.

4x = 3y - 9

3y = 4x + 9

Since the term "3y" is present in the other equation given, we can substitute the right side of this equation (4x + 9) into the other equation for 3y. This is shown below.

6x - 3y = -21

6x - (4x + 9) = -21

6x - 4x - 9 = -21

We can simplify the left side of the equation and solve for x.

2x - 9 = -21

2x = -12

x = -6

Now, we can substitute this value for x into one of our equations to solve for y.

4x = 3y - 9

4(-6) = 3y - 9

-24 = 3y - 9

-15 = 3y

y = -5

Therefore, the correct answer is x = -6 and y = -5.

Answers

The number of independent pieces of information used to calculate a statistic is called the degrees of freedom, which is frequently denoted by the letters v or df. I

What is the degree of freedom?

Itbis determined by subtracting the number of restrictions from the sample size. Subtract the number of relations from the number of observations to determine degrees of freedom. You need to deduct one (1) from the total number of observations, n, in order to calculate the degrees of freedom for a sample mean or average.

The degrees of freedom for the chi-square are calculated as df = (r-1)(c-1) where

r = the number of rows

c = the number of columns.

If the observed chi-square test statistic is greater than the critical value, the null hypothesis can be rejected.

So when f(x) has a reflection across the x-axis, this means that it goes from

f(x)—> -f(x)

So -f(x)=-(-9x+10)

And we know that -f(x)=g(x) because that is the function that is formed after reflecting f(x) across the x-axis. So the function g(x) will be

g(x)=-(-9x+10)

Simplifying this we get

Answers

There is a probability of 33.45% that the age of randomly selected CEO will be between 50 and 55 years old.

What does the math term "probability" mean?

The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out.              

                     Statistics is the study of events that follow a probability distribution.

Given that:

Mean = 56, standard deviation = 4, For 50:

z = (50 - 56) / 4 = -1.5

For 44:

z = (55 - 56) / 4 = -0.25

P(50 < x < 55) = P(z < -0.25) - P(z < -1.5) = 0.4013 - 0.0668 = 33.45

There is a probability of 33.45% that the age of randomly selected CEO will be between 50 and 55 years old.

c is y-intercept

The formula to find the slope between two coordinates is;

If we take the coordinates (4, 5000) and (12, 10000), we have;

Slope = (10000 - 5000)/(12 - 4)

Hello. Could someone help me to solve this question? The answer is 86.61cm.

Answers

The perimeter of the whole diagram in cm is derived as 86.6158 cm using trigonometric ratios.

Trigonometric ratios

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

Considering the angle P for right-angled triangle formed by extending the line PQ to the base of the trapezium, so that we have opposite side of 7 cm (22 cm - 15 cm)

so; sinP = 7/25.3

P = sin^(-1)(7/25.3)

P = 16.06

The isosceles triangle PQR have the angle;

Q = 180 - 2(16.06) {sum of interior angles of Isosceles triangle with two equal base angles}

Q = 147.88°

Considering the smaller right-angled triangle formed by the height of the trapezium and one side of the Isosceles triangle, we have its angle;

Q = 180° - 147.88° {sum of angles on a straight line}

Q = 32.12

also;

sin32.12 = 7/hypotenuse (one of the equal sides of the Isosceles triangle)

hypotenuse = 7/sin32.12

hypotenuse = 13.1655

The length TS is equal to the adjacent side of the smaller triangle, so;

cos32.12 = TS/13.1655

TS = 13.1655 × cos32.12

TS = 1.51503

Therefore, the perimeter of the whole diagram is;

25.3 cm + 22 cm + 15 cm + 13.1655 cm + 11.1503 cm = 86.6158 cm.

If both bouquets have 6 tickseeds, the first bouquet ( roses + tickseeds) has more flowers.

The problem can be solved using ratio.

Bouquet 1 :

Every 2 tickseeds there are 7 roses

Hence, the ratio

Tickseed : rose = 2 : 7    

If there are 6 tickseeds, then

2 : 7 = 6 : rose

rose = (6/2) x 7 = 21

Number of flowers = 6 tickseeds + 21 roses = 27 flowers

Bouquet 2 :

Every 3 tickseeds there are 4 daisies

Hence, the ratio

Tickseed : daisy = 3 : 4

If there are 6 tickseeds, then

3 : 4 = 6 : daisy

daisy = (6/3) x 4 = 8

Number of flowers = 6 tickseeds + 4 daisies = 10 flowers

Therefore, [tex]$W(\mathbf{x})$[/tex] is a linear transformation.

To check whether [tex]$W(\mathbf{x})$[/tex] is onto:

Define the linear transformations:

[tex]$$T_1: \mathbf{R} \rightarrow \mathbf{R}$ such that $T_1(\mathbf{x})=\mathbf{x}$[/tex]

[tex]$$T_2: \mathbf{R} \rightarrow \mathbf{R}$ such that $T_2(\mathbf{x})=-\mathbf{x}$[/tex]

Then, [tex]$T_2(\mathbf{x})=-\mathbf{x}=-T_1(\mathbf{x}) \Rightarrow T_2(\mathbf{x})=-T_1(\mathbf{x})$[/tex]

The range of both functions [tex]$T_1, T_2$ is $\mathbf{R}$[/tex] This is same as the co-domain of [tex]$T_1, T_2$[/tex]. So, they are onto functions.

If A and B are the two sets, if for every element of B, there is at least one or more element matching with set A, it is called the onto function.

Therefore, [tex]$T_1, T_2: \mathbf{R} \rightarrow \mathbf{R}$[/tex]are onto linear transformations.

And, [tex]$W=T_1+T_2: \mathbf{R} \rightarrow \mathbf{R}$[/tex] is a mapping.

Now, [tex]$W(\mathbf{x})=T_1(\mathbf{x})+T_2(\mathbf{x})$[/tex]

[tex]$$\begin{aligned}& =T_1(\mathbf{x})-T_1(\mathbf{x}) \\& =0\end{aligned}$$[/tex]

So, the range of [tex]$$W(\mathbf{x})$ is $\{0\} \neq \mathbf{R}($[/tex] co-domain of [tex]$W(\mathbf{x}))$[/tex]

Then, is [tex]$W(\mathbf{x})$[/tex] not onto.

So, the given statement is false.

To solve this problem, we need to use the formula for the volume of a rectangular prism, which is V = l × w × h, where l and w are the length and width of the base and h is the height.

We are given that the side length of the base of the building is 100 feet less than the height of the building, so the height of the building is h = l + 100, where l is the side length of the base. We can substitute this expression for h into the formula for the volume of the building:

V = l × w × (l + 100) = 2 million cubic feet

Since the building is 25 times as tall as the tower, the height of the tower is h = (1/25) × h = (1/25) × (l + 100). Substituting this expression for h into the formula for the volume of the building, we get:

V = l × w × (1/25) × (l + 100) = 2 million cubic feet

Solving this equation for l, we find that l = 500 feet. This is the side length of the base of the building, so the height of the building is h = l + 100 = 500 + 100 = 600 feet. The tower is (1/25) × 600 = 24 feet tall.

what is the coefficient of determination; how do you interpret this number? make a comment on the strength of the regression relationship

Answers

The coefficient of determination (also known as the R-squared) is a measure of the proportion of the variance in the dependent variable (the y-variable) that is explained by the independent variable (the x-variable).

It is denoted by r-squared and typically takes values between 0 and 1. A value of 0 indicates that the independent variable does not explain any of the variance in the dependent variable, while a value of 1 indicates that the independent variable explains all of the variance in the dependent variable. The coefficient of determination (also known as the R-squared) is a measure of the proportion of the variance in the dependent variable (the y-variable) that is explained by the independent variable (the x-variable). A higher R-squared value indicates a stronger regression relationship between the two variables.

Lucy wants to but a new car but needs money for the down payment. Her parents agree to lend her money at an annual rate of 5%, charged as simple interest. They lend her $4000 for 2 years. She makes no payments except the one at the end of that time.

Answer the following questions:
How much total interest will Lucy have to pay?
What will the total repayment amount be (including interest)

Answers

Answer:

To calculate the total interest that Lucy will have to pay, we need to use the formula for simple interest: I = P * R * T, where I is the interest, P is the principal (the amount borrowed), R is the interest rate (as a decimal), and T is the time in years. Using this formula, we can calculate the total interest that Lucy will have to pay as follows:

I = P * R * T

I = $4000 * 0.05 * 2

I = $400

Therefore, the total interest that Lucy will have to pay is $400.

________________________________________________________

To calculate the total repayment amount (including interest), we need to add the total interest to the original amount borrowed, which in this case is $4000. Therefore, the total repayment amount will be $4000 + $400 = $4400. This is the amount that Lucy will have to pay back to her parents at the end of the two-year period.

Step-by-step explanation:

Answer:

Total interest = $400

Total repayment (including interest) = $4,400

Step-by-step explanation:

Simple Interest Formula

[tex]\large\boxed{ \sf I = Prt}[/tex]

where:

I = Total interest.P = Principal amount.r = Interest rate (in decimal form).t = Time (in years).

Given:

P = $4,000r = 5% = 0.05t = 2 years

To find the total interest, substitute the given values into the formula and solve for I:

[tex]\implies \sf I=4000 \cdot 0.05 \cdot 2[/tex]

[tex]\implies \sf I=200 \cdot 2[/tex]

[tex]\implies \sf I=400[/tex]

Therefore, the total interest Lucy has to pay is $400.

The total repayment amount is the sum of the principal and the interest:

[tex]\implies \sf A=P+I[/tex]

[tex]\implies \sf A=4000 +400[/tex]

[tex]\implies \sf A=4400[/tex]

Therefore, the total repayment (including interest) is $4,400.

Expand the function.


f(x)=(3x+2)^4

Answers

The expanded equation of the function f(x) = (3x + 2)⁴ is f(x) = 81x + 216x³ + 216x² + 96x + 16

How to expand the function

From the question, we have the following parameters that can be used in our computation:

f(x) = (3x + 2)⁴

Using the pascal triangle at n = 4, we have the coefficients to be

Coefficient = 1     4     6     4     1

So, when the function f(x) = (3x + 2)⁴ is expanded, we have

f(x) = 1 * (3x)⁴ + 4 * (3x)³ * 2 + 6 * (3x)² * 2² + 4 * (3x) * 2³ + 1 * 2⁴

Evaluate

f(x) = 81x + 216x³ + 216x² + 96x + 16

Hence, the solution is f(x) = 81x + 216x³ + 216x² + 96x + 16

Which do you prefer: leaving √5 in radical form, or converting it to a decimal? Why? When would it be useful to use each?

Answers

I would prefer leaving the answer as a radical number as √5 since it is a shorter form and exact form of the answer.

How to express radical numbers?

My reasons for leaving it as a radical form or a decimal approximation are;

1) If we are trying to find an exact answer, then we should leave it as √5. For example, if we are told a square has an area of 5 square units, then it means that the exact length of the side is √5 units.

2) If √5 is the length of an object that has to be made to that specific length, then we would require an approximation. For example, if you are asked to make a square out of cardboard whose area is 5 square feet, then we will definitely need an approximation of √5 ft = 2.24 ft, which would help us make each side of the cardboard square in the length of 2.24 ft.
