What is f(+3) if f(x) = 5 x

Answer: x= 6

Step-by-step explanation:

Since the shape is a parallelogram, the angles will either be equal to each other or add up to 180.  

You can see they do not look the same so they add up to equal 180

12x + 3 +105 = 180

12x + 108 = 180

12x = 72

x = 6

The probability that you are correct by making a random guess is 1/5.

According to the given question.

On a multiple choice test, each question has 5 possible answers.

As we know that probability, is a measure of the likelihood of an event to occur. It is calculated by taking the ratios of favorable outcomes to the total number of outcomes.

Here, it is given that there are 5 possible answers of one question.

⇒ Total number of outcomes = 5

Also, only one answer will correct out of 5 possible answers.

Which means, total number of favorable outcomes = 1

Therefore, the probability that you are correct by making a random guess

= favorable outcomes/total number of outcomes

= 1/5

Hence, the probability that you are correct by making a random guess is 1/5.

The equation of the line that passes through the points (-1, -2) and (1, 4) is y = 3x + 1.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

To find the equation of the line that passes through the points (-1, -2) and (1, 4), we can use the point-slope form of the equation of a line -

y - y1 = m(x - x1)

where m is the slope of the line, and (x1, y1) is one of the given points on the line.

First, we can find the slope of the line by using the two given points -

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

m = (4 - (-2)) / (1 - (-1))

m = 6 / 2

m = 3

Now we can choose one of the given points, say (-1, -2), and substitute the slope and the coordinates into the point-slope form of the equation -

y - (-2) = 3(x - (-1))

Simplifying, we get that -

y + 2 = 3(x + 1)

Expanding and rearranging -

y + 2 = 3x + 3

y = 3x + 1

Therefore, the equation of the line is obtained as y = 3x + 1.

Answer:

y = - \(\frac{3}{5}\) x + 1

Step-by-step explanation:

Parallel lines have equal slopes

Calculate m of CD using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = C(- 3, 4) and (x₂, y₂ ) = D(7, - 2)

m = \(\frac{-2-4}{7+3}\) = \(\frac{-6}{10}\) = - \(\frac{3}{5}\) , thus

y = - \(\frac{3}{5}\) x + 1 ← is parallel to CD

Using algebraic expressions and equations to solve this problem, a 19- inch piece of steel is cut into three pieces measuring 2 inches, 4 inches, and 13 inches.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

If the second piece is twice as long as the first piece, we can write this as an algebraic expression "2x" where x is the length of the first piece.

If the third piece is three inches more than five times the length of the first piece, we can write this as an algebraic expression "3 + 5x" where x is the length of the first piece.

If the three pieces were cut from a single piece of steel 19-inches long, we can write the equation for the sum using the algebraic expressions.

let x = length of first piece

2x = length of second piece

3 + 5x = length of third piece

x + 2x + 3 + 5x = 19 inches

Solving for x,

8x = 19 -3

8x = 16

x = 2 inches

length of first piece = 2 inches

Substitute the value of x in the expressions for the second and third piece.

length of second piece = 2x

length of second piece = 2(2)

length of second piece = 4 inches

length of third piece = 3 + 5x

length of third piece = 3 + 5(2)

length of third piece = 3 + 10

length of third piece = 13 inches

Answer:

Step-by-step explanation:

Answer:

\(\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0\)

Or:

\(pm = qn \text{ and } pn + qm \neq 0\)

Step-by-step explanation:

We are given two complex numbers:

\(\displaystyle m + ni \text{ and } p + qi\)

Where m, n, p, and q are real numbers.

And we want to determine the relationship among m, n, p, and q such that the product of the two complex numbers will only have an imaginary part.

Find the product:

\(\displaystyle \begin{aligned} (m+ni)(p+qi) &= p(m+ni) + qi(m+ni) \\ &= (pm + pni) + (qmi + qni^2) \\ &= (pm + pni) + (qmi - qn) \\ &= (pm - qn) + i(pn + qm) \end{aligned}\)

Therefore, for the product to have only an imaginary part, the real part must be zero and the imaginary part must not be zero. That is:

\(\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0\)

In conclusion, the relationship between m, n, p, and q is:

\(\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0\)

Or:

\(pm = qn \text{ and } pn + qm \neq 0\)

The x-coordinates of the left edges of the rectangles are 1,5/4,6/4,7/4.

The area of this region with a Riemann Sum is 0.7595.

A specific type of approximation of an integral by a finite sum in mathematics is known as a Riemann sum. It bears the name of the German mathematician Bernhard Riemann from the nineteenth century. Approximating the area of functions or lines on a graph, as well as the length of curves and other approximations, is a highly typical use.

Given function is f(x) = 1/x on the interval [1,2] is shown.

The four rectangles of width 1/4 are present.

From the figure we can see that the x coordinate of the left edges of the rectangle are:

1,5/4,6/4,7/4

Now we plug these values in the function to find the height of rectangles.

For x=1 ,f(x) = 1

For x=5/4 ,f(x) = 4/5

For x=6/4 ,f(x) = 4/6

For x=7/4 ,f(x) = 4/7

Now, Area = length*width, and width of each rectangle is 1/4

Area of rectangle 1 = 1*1/4 = 1/4

Area of rectangle 2 = 4/5*1/4 = 1/5

Area of rectangle 3 = 4/6*1/4 = 1/6

Area of rectangle 4 = 4/7*1/4 = 1/7

Total Area is = 1/4+1/5+1/6+1/7  = 0.7595

This is an overestimation of ln(2).

Step-by-step explanation:

The compound event probability of spinning an even number and flipping heads is P ( A ) = 1/4

Given data ,

Let the total number of outcomes in spinning a spinner be = 6

The number of even outcomes = 3

Let the number of outcomes in flipping a coin = 2

So , the probability of landing an even number = 3/6 = 1/2

The probability of landing a heads = 1/2

And , probability of spinning an even number and flipping heads is given by P ( A ) = probability of landing a heads x probability of landing an even number

On simplifying , we get

P ( A ) = 1/2 ( 1/2 )

P ( A ) = 1/4

Hence , the probability is 1/4 or 25 %

False. The given statement is not a valid proof of the theorem because it is circular.

The proof starts with the assumption that there exists an integer k such that n < k < n^2 and then uses this assumption to conclude that the theorem is true. However, this does not actually prove the existence of k, it simply restates the theorem. A valid proof would need to start with some other set of premises and use logical deduction to arrive at the conclusion that such a k exists.

Given matrix A = [[-1, -5q, 14m, 1348n]] and matrix B = [[-11v, 9w, -3, -2r, -141]], we need to compute the entries of E = A^T - B.

The transpose of matrix A, denoted as A^T, is obtained by interchanging the rows and columns of matrix A. So, A^T = [[-1], [-5q], [14m], [1348n]].

To compute e21, we find the entry at the second row and first column of E, which is obtained by subtracting the corresponding entries of A^T and B. Therefore, e21 = -1 - (-11v) = 11v - 1.

To compute a31 - b23 + e12, we consider the entry at the third row and first column of A^T, subtract b23 from it, and add e12. Thus, a31 - b23 + e12 = 14m - (-3) + (-5q) = 14m + 3 - 5q.

The final answers for (a) e21 and (b) a31 - b23 + e12 are 11v - 1 and 14m + 3 - 5q, respectively, in exact, reduced form.
