The formula for a triangular prism is

\( \frac{1}{2} a \times h\)

where a is the area of the triangle.

The area of a triangle is

\( \frac{4 \times 5}{2} = 10\)

so the volume is

\(10 \times 12 = 120\)

Answer:

well if you're looking for angles then

angle ADB = 30°

angle CBD = 80°

angle CDB = 120°

but they asked to classify triangle ADC ,whose measurements are 90° , 40° and 50° ...so of they're asking what type of triangle then it is a right angled triangle.

Answer:

Triangle ADC is a right triangle.

Step-by-step explanation:

Triangles Classification

An acute triangle is a triangle with three acute angles or with less than 90° each.

An obtuse triangle has one obtuse angle or more than 90°.

A right triangle has one right angle of 90°

From the figure, we can see angle D is marked as a right angle (90°), thus triangle ADC is a right triangle.

To complete the answer, triangle ADB is obtuse (has an angle of 100°), and triangle ABD is acute.

P-value of less than 0.05 is typically considered statistically significant, indicating that the relationship between the variables in the regression equation is unlikely to be due to chance.

To find the p-value for the regression equation that fits the given data, you would need to conduct a regression analysis. This involves analyzing the relationship between the variables in the data set and determining whether there is a statistically significant relationship. Unfortunately, the data set you provided does not have any indication of what the variables are or what the regression equation is, so it is impossible to provide a specific answer to your question.
However, if you do conduct a regression analysis and obtain a p-value, you would round your answer to four decimal places as requested in the question. The p-value is a decimal value that represents the probability of obtaining the observed results if the null hypothesis is true. Based on the data provided, we first need to calculate the regression equation. However, the data seems to be presented in an unclear format. Please provide the data as pairs of x and y values, like this: (x1, y1), (x2, y2), (x3, y3), and so on. Once you provide the data in this format, I'll be happy to help you find the p-value for the regression equation, rounded to four decimal places.

The equation of the  circle , with diameter  DEis (x - 5)² + (y - 7)² = 80

An equation is an expression that appears as the relationship between two or more variables and numbers. since the  standard equation  for a circle  is (x - h)² + (y - k)² = r², where    (h, k)  is the center of the circle and r is the radius. It is given that the diameter of the circle is at D(-3, 3) and E(13, 11). So the coordinate of the center is:

h = (13 + (-3))/2 = 5

k = (3 + 11)/2 = 7

(h, k) = (5, 7) and the  Radius is diameter / 2 = 8√5 ÷ 2 = 4√5.

the equation will be : (x - 5)² + (y - 7)² = (4√5)² => (x - 5)² + (y - 7)² = 80

A 95% confidence interval for percent of american adults who believe in aliens:  (0.6578, 0.7822)

In this question we have been given that in a survey conducted on an srs of 200 american adults, 72% of them said they believed in aliens

We need to find the 95% confidence interval for percent of american adults who believe in aliens.

95% confidence interval = (p ± z√[p(1 - p)/n])

Here, n = 200

p = 72%

p = 0.72

And the z-score for 95% confidence interval is 1.960

The upper limit of interval would be,

(p + z√[p(1 - p)/n])

= 0.72 + 1.960 √[0.72(1 - 0.72)/200]

= 0.72 + 1.960 √[(0.72 * 0.28)/200]

= 0.72 + 1.960 √0.001008

= 0.72 + 0.0622

= 0.7822

The lower limit of interval would be,

(p - z√[p(1 - p)/n])

= 0.72 - 1.960 √[0.72(1 - 0.72)/200]

= 0.72 - 1.960 √[(0.72 * 0.28)/200]

= 0.72 - 1.960 √0.001008

= 0.72 - 0.0622

= 0.6578

Therefore, a 95% confidence interval = (0.6578, 0.7822)

The probability of event B, P(B), is 0.1667.

To find the probability of event B, we can use the formula for the probability of the intersection of two independent events:

P(A and B) = P(A) * P(B)

We are given that P(A and B) = 0.10 and P(A) = 0.6.

Let's substitute these values into the formula:

0.10 = 0.6 * P(B)

To solve for P(B), we divide both sides of the equation by 0.6:

0.10 / 0.6 = P(B)

Simplifying the division:

P(B) ≈ 0.1667

Option (A) - 4 is the correct answer.

The value of x for linear equation -6x + 4x = 8 is - 4.

If a variable's maximum power constantly equals 1, the equation is considered linear equation. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. Here, A is a coefficient, B is a constant, and x is a variable.

The given equation is -6x + 4x = 8.
Simplifying the above equation.
-2x = 8
Now, dividing both sides by -2.

x = -4
Therefore the value of x in equation -6x + 4x = 8 is -4.

Answer:

The range of the function is all real numbers greater than or equal to -1.

Step-by-step explanation:

Second order polynomials are continous and have an absolute maximum or minimum that restricts the set of the range associated with the function. A fair approach to estimate the range is rewritting the expression into parabola form, which is:

\(y - k = C \cdot (x-h)^{2}\)

Where:

\(C\) - Vertix parameter, dimensionless. If \(C > 0\), then vertix is an absolute minimum, but if \(C < 0\), vertix is an absolute maximum.

\(x\) - Independent variable, dimensionless.

\(y\) - Dependent variable, dimensionless.

\(h\) - Location of the vertix with respect to the independent variable, dimensionless.

\(k\) - Location of the vertix with respect to the dependent variable, dimensionless. This value restrics the set corresponding to the range of the polynomic function.

First, we have to expand polynomial into its standard form:

\(y = (x-4)\cdot (x-2)\)

\(y = x^{2}-6\cdot x +8\)

Now, we are going to complete the square and factorize the resultant expression until parabola form is obtained:

\(y = x^{2}-6\cdot x + 9 -9 + 8\)

\(y = (x-3)^{2} -1\)

\(y + 1 = 1 \cdot (x-3)^{2}\)

Since the vertix parameter is positive, then vertix is an absolute minimum. The location of the vertix with respect ot the depedent variable is \(k = -1\). Therefore, the range of the function is all real numbers greater than or equal to -1.

The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Madelyn has a total of 15 dimes and quartets in her piggy bank. The total amount of money in her piggy bank is $2.85.

Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equations are given as,

0.10x + 0.25y = 2.85       ....1

x + y = 15                         ....2

From equations 1 and 2, then we have

0.10(15 - y) + 0.25y = 2.85

1.5 - 0.10y + 0.25y = 2.85

0.15y = 1.35

y = 9

Then the value of the variable 'x' is given as,

x + 9 = 15

x = 6

The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.

We are given an item that costs 490 dollars before tax, the sales tax of the item is $44.10, which means the item will cost $534.10 in total. Assuming what you are asking is to find the percentage of the sales tax we will use the formula to calculate percentages, and then add that answer to our before cost to confirm our answer.

Formula to calculate percentages:

\(\frac{p\times n}{100}\)
\(p=9\)
\(\frac{9\times490}{100}\)
\(9\times490=4410\)
\(4410\div100=44.1=44.10\)

The domain of function f(x) is (-∞, -6) ∪ (-6, ∞).

The domain of function g(x) is (-∞, -2) ∪ (-2, 2) ∪ (2, ∞).

We have,

To find the domain of a function, we need to determine the values of x for which the function is defined.

For f(x) = x² / (x + 6), the function is defined for all real numbers except when the denominator (x + 6) equals zero, as division by zero is undefined. So, we set x + 6 ≠ 0 and solve for x:

x + 6 ≠ 0

x ≠ -6

Therefore, the domain of f(x) is all real numbers except -6.

In interval notation, the domain is (-∞, -6) ∪ (-6, ∞).

For g(x) = (x - 2) / (x² - 4), the function is defined for all real numbers except when the denominator (x² - 4) equals zero.

So, we set x² - 4 ≠ 0 and solve for x:

x² - 4 ≠ 0

(x - 2)(x + 2) ≠ 0

This equation is satisfied when x ≠ 2 and x ≠ -2.

Therefore, the domain of g(x) is all real numbers except 2 and -2.

In interval notation, the domain is (-∞, -2) ∪ (-2, 2) ∪ (2, ∞).

Thus,

The domain of f(x) is (-∞, -6) ∪ (-6, ∞).

The domain of g(x) is (-∞, -2) ∪ (-2, 2) ∪ (2, ∞).
