The magnitude of ab -> is 7.28 units and the direction is 111.8°.

To find the magnitude and direction of ab ->, we first need to find the components of the vector ab ->. The components can be found by subtracting the coordinates of a from the coordinates of b.

So, the x-component of ab -> is (-2) - (-4) = 2 and the y-component of ab -> is 13 - 6 = 7.

The magnitude of ab -> can be found using the Pythagorean theorem:

|ab ->| = sqrt((2)^2 + (7)^2) = 7.28 units (rounded to two decimal places).

The direction of ab -> can be found using trigonometry.

tan(theta) = (y-component of ab ->) / (x-component of ab ->) = 7/2

theta = arctan(7/2) = 111.8° (rounded to one decimal place)

Therefore, the magnitude of ab -> is 7.28 units and the direction is 111.8°.

Answer:

27°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

let the third angle be x , then

x + 90° + 63° = 180°

x + 153° = 180° ( subtract 153° from both sides )

x = 27°

Answer:

27 degrees

Step-by-step explanation:

A right angled triangle has 1 angle as 90 degree. And as you know the other angle is 63 degree, and the angle sum property of a triangle is 180 degrees. So-

Let's take 'x' as the other angle.

90 + 63 + x = 180

153 + x = 180

x = 180 - 153 = 27

x = 27 degrees

So, the other angle is 27 degrees.

All the angles of the right-angled triangle are- 90, 63, 27.

Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).

The length of a one-dimensional object, such as a line, curve, or straight segment, is measured by the fundamental physical quantity known as length. It is a way to gauge the separation between two points or the size of an object along a specific axis. The International System of Units (SI) uses metres as the unit of length (m). One of the most important ideas in geometry is length, which is used to describe the characteristics of geometric forms and shapes. For instance, the length of a circle is the distance around its circumference, whereas the length of a line segment is the distance between its endpoints.

given

(A) We must first determine the length of chord PQ in order to determine the length of segment PM. Since LM is the perpendicular bisector of PQ in the figure, PM is equal to MQ. PQ's length is 20 cm, so PM and MQ's lengths are each 50 percent of that, or:

PM=MQ=20/2=10 cm

Sqrt(PM2 + LM2) = PL

(d) When we enter the values from parts (a) and (c), we obtain:

Sqrt(10 + 15) = PL

Sqrt(100 + 225) = PL

Sqrt = PL (325)

PL ≈ 18.03 cm

Hence, section PL measures about 18.03 cm in length (rounded to the nearest hundredth digit).

Therefore, the t-score to be used for a 99% confidence interval estimate for the population mean is 2.692.

To find the t-score for a 99% confidence interval estimate for the population mean with a random sample of 45 career changers, we need to use the t-distribution. The t-distribution is used when the population standard deviation is unknown, and we estimate it using the sample standard deviation.

Since the sample size is 45, which is greater than 30, we can approximate the t-distribution with the standard normal distribution (z-distribution). However, to be more accurate, we can still use the t-distribution. For a 99% confidence level, we need to find the critical value associated with a confidence level of 0.995 (since we divide the confidence level by 2 for a two-tailed test).

The degrees of freedom for a sample size of 45 is:

(n - 1) = (45 - 1)

= 44

Using a t-table or a statistical calculator, we can find that the t-score associated with a 99% confidence level and 44 degrees of freedom is approximately 2.692.

There are 4845 ways to choose four books from a reading list of 20 books.

To calculate the number of ways to choose four books from a list of 20, we can use the combination formula. The formula for calculating combinations is given by nCr = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to be chosen. In this case, we have 20 books in the reading list, and we want to choose 4 books. Using the combination formula, we can calculate the number of ways as follows:

20C4 = 20! / (4!(20-4)!)

     = (20 * 19 * 18 * 17) / (4 * 3 * 2 * 1)

     = 4845

Andualem needs to sell approximately 113 furniture pieces in order to break even.

To break even, Andualem needs to sell enough furniture to cover the total investment cost and the cost per item. By dividing the total investment cost by the profit per item, we can determine the volume of furniture Andualem needs to sell in order to break even.

To calculate the volume of furniture necessary for Andualem to break even, we need to consider the total investment cost and the cost per item.

The total investment cost includes the cost of plant and equipment, which is estimated to be $225,000. The cost per item includes labor, materials, packaging, and shipping, which amounts to $1,000 per item.

To break even, Andualem needs to cover both the total investment cost and the cost per item through the sale of furniture. The profit per item can be calculated as the selling price minus the cost per item, which is $3,000 - $1,000 = $2,000.

Now, to determine the volume of furniture necessary for Andualem to break even, we divide the total investment cost by the profit per item.

Volume = Total investment cost / Profit per item

Volume = $225,000 / $2,000

Volume = 112.5

Therefore, Andualem needs to sell approximately 113 furniture pieces in order to break even. It is important to note that the volume calculated is rounded up to the nearest whole number, as selling fractional furniture pieces is not feasible.

The equilibrium constant can be determined using the concentrations of reactants and products at equilibrium. In this case, the initial concentrations of substances A, B, and C are given as [A] = 0.50 M, [B] = 0.75 M, and [C] = 1.2 M, while the equilibrium concentration of C is [C] = 1.0 M.

The equilibrium constant, denoted as K, is defined as the ratio of the product of the concentrations of the products to the product of the concentrations of the reactants, each raised to the power of their stoichiometric coefficients. In this case, the balanced chemical equation is not provided, so we cannot directly calculate the equilibrium constant.

To determine the equilibrium constant, we need the balanced chemical equation representing the reaction.

The exercise involves finding the product C = AB, where matrix A is given by [2 9] and matrix B is given by [3 6 1]. We need to perform the matrix multiplication to obtain the resulting matrix C.

Let's calculate the matrix product C = AB step by step:

Matrix A has dimensions 2x1, and matrix B has dimensions 1x3. To perform the multiplication, the number of columns in A must match the number of rows in B.

In this case, both matrices satisfy this condition, so the product C = AB is defined.

Calculating AB:

AB = [23 + 912 26 + 94 21 + 95]

[103 + 612 106 + 64 101 + 65]

Simplifying the calculations:

AB = [6 + 108 12 + 36 2 + 45]

[30 + 72 60 + 24 10 + 30]

AB = [114 48 47]

[102 84 40]

Therefore, the product C = AB is:

C = [114 48 47]
