When the measure of ∠4 is 120∘, the measure of ∠1 is 60∘. Please answer in " always true, sometimes true, or never true

Using the fact that the sum of the interior angles must be 180°, we will get:

∠B  = 101°

XYZ  = 76°

Let's solve the problem for the first triangle.

Ok, remember that the sum of the interior angles of any triangle is always equal to 180°, then we can write:

∠B + ∠C + ∠A = 180°

Replacing the values that we know we will get:

∠B + 44° + 35° = 180°

Now we can solve that equation to get:

∠B = 180° - 44° - 35° = 101°

So the answer is 101°.

For the second triangle, the interior angles are:

(5x + 1)

(3x + 11)

And, the one at the right is:

180° - 12x + 20

Then the sum gives:

(5x + 1) + (3x+  11) + 180° - 12x + 20 = 180

5x + 1 + 3x + 11 - 12x + 20 = 0

-4x + 32 = 0

-4x = -32

x = 32/4 = 8

And XYZ = 12x - 20 = 12*8 - 20 = 76

Deposit of $1400 will be double in 14.2 years.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period.

Given,

Deposited Principal Amount P = $1400

Rate of interest r = 5% = 0.05

Amount A = double the deposit = 2× $1400 = $2800

Let the number of years = n

Amount A = P(1 + r)ⁿ

$2800 = $1400(1 + 0.05)ⁿ

(1 + 0.05)ⁿ = 2

Taking log on both side

n log(1.05) = log2

n =  log2 / log(1.05)

n = 0.3010/0.0212

n = 14.2

Hence, It will take 14.2 years to double the deposit of $1400.

The residual in this case is 4.72%, which is calculated by taking the difference between the predicted value (32.54%) and the actual value (27.82%).

The political scientist's least squares regression equation predicted that 32.54% of people in Wyoming would vote for Obama in 2012. However, the actual percentage of people who voted for Obama in Wyoming in 2012 was 27.82%, which was lower than the predicted value. This difference between the predicted and actual value is the residual, which in this case is 4.72%.

The "best" solution z+ = A^+b is the one that minimizes the 2-norm of the residual vector r = b - Az. In general, not all right-hand sides b will have a unique solution z+, and even if there is a solution, it may not be exact (i.e., Az ≠ b).

To find the pseudoinverse of a matrix A, the first step is to take the singular value decomposition (SVD) of A, which can be written as A = UΣV^T, where U and V are orthogonal matrices and Σ is a diagonal matrix with nonnegative singular values. The pseudoinverse of A is given by A^+ = VΣ^+U^T, where Σ^+ is the same as Σ except that the nonzero elements of Σ are replaced by their inverses.

Next, the projection matrices are given by AtA and AA+, which are used to project a vector onto the column space and the row space of A, respectively.

The "best" solution z+ = A^+b is the one that minimizes the 2-norm of the residual vector r = b - Az. In general, not all right-hand sides b will have a unique solution z+, and even if there is a solution, it may not be exact (i.e., Az ≠ b).

Whether a solution is exact or unique depends on the rank of A and the number of linearly independent columns and rows. If the rank of A is equal to the number of columns, then the solution is unique, otherwise, the solution may not be unique.

Answer: 4 aka the one on the bottom

Step-by-step explanation: There is 3 sections, only one filled in to make 1/3, then you split that in half

Answer:

1/6

Step-by-step explanation:

If we know that only 1/3 of the ice cream cake was left, and George ate 1/2 of that, we can use the equation:

1/3 ÷ 2 = 1/6

If we were to divide a fraction, we would take the denominator, in this case its 3, and multiply that by the amount being divided, which is 2.

2 × 3 = 6

Now that we have 6, simply add it back to the fraction denominator with the same numerator which is 1. This would make it 1/6.

Answer:

x −2 −1 0

y −1 0 1

Step-by-step explanation:

Condition:

A linear relationship is proportional if the ratio of the change in the dependent variable to the change in the independent variable is constant. This constant is known as the proportionality constant and can be represented by "k" in the equation y = kx. When a linear relationship is proportional, there is a direct relationship between the variables and as one increases, the other increases and vice versa.

The second table (x = -2, -1, 0 and y = -1, 0, 1) represents a linear relationship that is also proportional. A proportional relationship means that the ratio of y to x remains constant, or in other words, y is a constant multiple of x. In this table, for every 1 unit increase in x, y increases by 1 unit, making it proportional.

The third table represents a linear relationship that is also proportional.

Your foot measure in centimeter is 4.25 centimeters and the proportion is 10.8 inches / 2.54 centimeters = x centimeters.

A proportion is an equation that states that two ratios are equal. It's often used to convert from one unit of measurement to another.

In your case, you want to convert 10.8 inches to centimeters, so you'll use a proportion to help you do that.

Here the correct proportion to use is 10.8 inches / 2.54 centimeters = x centimeters.

In this proportion, the first ratio on the left side of the equation represents 10.8 inches in terms of centimeters, and the second ratio on the right side of the equation represents x centimeters in terms of inches.

Since we know the conversion factor between inches and centimeters, 2.54 centimeters per inch, we can substitute that into the proportion.

=> 10.8 inches / 2.54 centimeters = x centimeters

=> 10.8 inches / 2.54 centimeters

=> 10.8 / 2.54 centimeters = 4.25 centimeters.

Therefore, 10.8 inches is equal to 4.25 centimeters.

Answer: Diploid cells divide to form four haploid daughter cells during mitosis.

Step-by-step explanation:

The answer is: Sister chromatids separate to form haploid daughter cells during meiosis.

One of a chromosome's two identical halves that has undergone replication in order to facilitate cell division is referred to as a chromatid. A chromosomal region known as the centromere is where the two "sister" chromatids are fused.

One of the two identical copies of a duplicated chromosome is called a chromatid. At the centromere, a portion of the chromosome, the twin copies of the DNA join together during cell division. Sister chromatids are those that are joined. A chromosome is a protein and DNA-based structure that resembles a thread. It contains an organism's whole genetic makeup. Parents pass this on to their children. One of a chromosome's halves is called a chromatid. There is just one chromatid per chromosome.

The chromatids in each thread-like structure in the chromosome are the result of the chromosome's DNA replicating itself. Haploid cells are produced as a result of the segregation of the chromatids during meiosis II.

A parallelogram is a two-dimensional shape with four straight sides that are parallel to one another and with opposite sides that are of equal length. The parallel and equal lengths of the opposing sides give the shape its name.

A rectangle that has been extended or contracted in one direction, or two congruent adjacent rectangles combined, can be used to describe a parallelogram.

a. The scale factor, when a dilation is carried out with centre of dilation A, is the ratio of the lengths of the corresponding sides of the pre-image and image. If the parallelograms ABCD and AB'C'D' have equivalent sides with lengths of AB and AB', respectively, the scaling factor is AB'/AB.

b. Set n equal to the total number of parallelograms ABCD that can fit inside parallelogram AB'C'D'.

Then, by multiplying the area of the parallelogram AB'C'D' by the area of the parallelogram ABCD, the area of the parallelogram AB'C'D' is equal to n times the area of the parallelogram ABCD.

c. The area of the parallelogram AB'C'D' is exactly proportional to the area of the parallelogram ABCD; as a result, if the scale factor of the dilation is k, the area of the parallelogram AB'C'D' is equal to k2 times the area of the parallelogram ABCD.

d. If the area of parallelogram ABCD is 12 square units, then the area of parallelogram AB'C'D' is equal to k2, or k2 times, the area of parallelogram ABCD.

To determine the number of rectangles needed to achieve a desired accuracy, one could start with a small number of rectangles, calculate the approximation error, and then increase the number of rectangles until the error is within the desired range.

The number of rectangles to use in a rectangle approximation of a definite integral depends on several factors:

The desired accuracy: The smaller the desired accuracy, the more rectangles will be required.

The shape of the function: If the function is highly curved, more rectangles will be required to capture the shape of the function than if the function is more linear.

The range of integration: The larger the range of integration, the more rectangles will be required.

In general, to determine the number of rectangles needed to achieve a desired accuracy, one could start with a small number of rectangles, calculate the approximation error, and then increase the number of rectangles until the error is within the desired range. Alternatively, one can use mathematical techniques such as adaptive quadrature methods that automatically adjust the number of rectangles to achieve a desired accuracy.

As a result, the radius of convergence, R, is equal to one. As a result, f(x) = x(1 + 8x)^2 = x(1 + 16x + 64x^2 +...) = x + 16x^2 + 64x^3 +... This is the function f's power series representation (x).

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example.

Here,

The power series representation for f(x) = x(1 + 8x)^2 can be found by expanding the function (1 + 8x)^2 as a Taylor series centered at x = 0:

(1 + 8x)^2 = 1 + 16x + 64x^2 + ...

So, f(x) = x(1 + 8x)^2 = x(1 + 16x + 64x^2 + ...) = x + 16x^2 + 64x^3 + ...

This is the power series representation for the function f(x).

To determine the radius of convergence, R, we use the formula:

R = 1 / limsup |a_n|^(1/n)

where a_n is the nth coefficient in the power series and limsup refers to the limit superior of the sequence {|a_n|^(1/n)}.

In this case, a_n = 16n x^n, so |a_n|^(1/n) = |16n|^(1/n) * |x|^(1/n). Since |16n|^(1/n) is a constant, the limit superior is just equal to |x|^(1/n). Therefore,

R = 1 / limsup |a_n|^(1/n) = 1 / |x|^(1/n) = 1

So, the radius of convergence, R, is equal to 1. So, f(x) = x(1 + 8x)^2 = x(1 + 16x + 64x^2 + ...) = x + 16x^2 + 64x^3 + ... This is the power series representation for the function f(x).

The PPF diagram shows the maximum output of two products that an economy can produce at a given time, and it is shaped like a curve. When farm fields are left unused, the amount of agricultural products that can be produced is decreased, resulting in a shift in the PPF curve inwards. This means that the economy has to sacrifice other goods to maintain the same level of production of agricultural products, leading to an opportunity cost. Thus, leaving farm fields unused has implications for the economy's PPF diagram, as it reduces the output of agricultural products, resulting in a shift in the PPF curve inwards.
