Answer:

The angles are

∠A = 90°, ∠B = 26.56°, ∠C = 63.43°

Step-by-step explanation:

We have that the angles of a vector are given as follows;

\(cos\left ( \theta \right ) = \dfrac{\mathbf{a\cdot b}}{\left | \mathbf{a} \right |\left | \mathbf{b} \right |}\)

Whereby the vertices are represented as

A= (2, 5, 0), B = (4, 11, 0), C = (-1, 6, 0),

AB =(4, 11, 0) - (2, 5, 0) = (2, 6, 0) ,  BA = (-2, -6, 0)

BC = (-1, 6, 0) - (4, 11, 0) = (-5, -5, 0), CB = (5, 5, 0)

AC = (-1, 6, 0) - (2, 5, 0) = (-3, 1, 0), CA = (3, -1, 0)

θ₁ = AB·AC

a·c = a₁c₁ + a₂c₂ + a₃c₃ = 2×(-3) + 6×1 = 0

Therefore, θ₁ = 90°

BA·BC = (-2)×(-5) + (-6)×(-5) = 40

\({\left | \mathbf{}BA \right |\left | \mathbf{}BC \right |}\) = (√((-2)² + (-6)²)) × (√((-5)² + (-5)²)) = 44.72

cos(θ₂) = 40/44.72 = 0.894

cos⁻¹(0.894) =θ₂= 26.56°

CA·CB = 5×3 + 5×(-1) = 10

\({\left | \mathbf{}CA \right |\left | \mathbf{}CB \right |}\) = (√((3)² + (-1)²)) × (√((5)² + (5)²)) = 22.36

10/22.36 = 0.447

cos(θ₃) = 0.447

θ₃ = cos⁻¹(0.447) = 63.43°.

The economy size is more economical, as you will get 2kg for $3.15, which comes out to be $1.58 per kg, while the regular size will cost you $0.65 per gram.

To determine which option is more economical, we need to calculate the cost per unit of weight for each detergent.

For the economy size, the cost per kilogram is:

Cost = $3.15

Weight = 2 kg

Cost per kilogram = Cost / Weight = $3.15 / 2 kg = $1.575/kg

For the regular size, the cost per kilogram is:

Cost = $0.60

Weight = 920 g = 0.92 kg

Cost per kilogram = Cost / Weight = $0.60 / 0.92 kg = $0.652/kg

Therefore, the regular-size detergent is more economical as it has a lower cost per kilogram.

The critical points are (2,1) and (0,0). Given, z = 3x² - xy + 2y² - 4x - 7y + 12.1. Find the critical points at which the function may be optimized.

To find the critical points, we need to solve the following system of equations: ∂z/∂x = 0, ∂z/∂y = 0∂z/∂x = 6x - y - 4 = 0∂z/∂y = -x + 4y - 7 = 0By solving these equations, we get two critical points: (2,1) and (0,0).2. Determine whether at the computed points, the function takes on its maximum or minimum value.

To determine whether each critical point is a maximum, minimum, or saddle point, we need to compute the second partial derivatives of z: ∂²z/∂x² = 6, ∂²z/∂y² = 4, ∂²z/∂x∂y = -1At the point (2,1), the second partial derivatives satisfy the condition (∂²z/∂x²)(∂²z/∂y²) - (∂²z/∂x∂y)² = (6)(4) - (-1)² = 25 > 0 and ∂²z/∂x² > 0, so z has a minimum value at this point.At the point (0,0), the second partial derivatives satisfy the condition (∂²z/∂x²)(∂²z/∂y²) - (∂²z/∂x∂y)² = (6)(4) - (-1)² = 25 > 0 and ∂²z/∂x² > 0, so z has a minimum value at this point.Therefore, the function z = 3x² - xy + 2y² - 4x - 7y + 12 is optimized at (2,1), where the minimum value is z = 3(2)² - (2)(1) + 2(1)² - 4(2) - 7(1) + 12 = -10.

Step-by-step explanation:

Because adding to or subtracting from the x will translate (shift or slide) your figure left or right (horizontally) and adding to or subtracting from the y will slide or shift the polygon up or down (vertically) So, both can happen and it need not be by the same amount.

Answer: In physics, when you break a vector into its parts, those parts are called its components. For example, in the vector (4, 1), the x-axis (horizontal) component is 4, and the y-axis (vertical) component is 1. Typically, a physics problem gives you an angle and a magnitude to define a vector; you have to find the components yourself using a little trigonometry.

Suppose you know that a ball is rolling on a flat table at 15 degrees from a direction parallel to the bottom edge at a speed of 7.0 meters/second. You may want to find out how long the ball will take to roll off the edge 1.0 meter to the right.

Define your axes so the ball is at the origin initially and the x-axis is parallel to the bottom edge of the table (refer to the figure). Therefore, the problem breaks down to finding out how long the ball will take to roll 1.0 meter in the x direction. To find the time, you first need to know how fast the ball is moving in the x direction.

Answer:

the radius is 5 cubic meters

When constructing a confidence interval for a population mean from a sample of size 28, the number of degrees of freedom (df) for the critical t-value is 27.

To construct a confidence interval for a population mean using a sample size of 28, we need to determine the number of degrees of freedom (df) for the critical t-value.

The number of degrees of freedom is equal to the sample size minus 1. In this case, the sample size is 28, so the number of degrees of freedom would be 28 - 1 = 27.

To find the critical t-value, we need to specify the confidence level. Let's assume a 95% confidence level, which corresponds to a significance level of 0.05.

Using a t-table or statistical software, we can find the critical t-value associated with a sample size of 28 and a significance level of 0.05, with 27 degrees of freedom.

Once we have the critical t-value, we can then construct the confidence interval for the population mean.

In conclusion, when constructing a confidence interval for a population mean from a sample of size 28, the number of degrees of freedom (df) for the critical t-value is 27.

The outstanding balance on the loan at the end of the 2nd year would be P54,000.

The loan of P60,000 is being amortized in four equal payments over four years. Each payment includes both the principal amount and the interest. The interest rate on the outstanding loan is 15 percent.

To calculate the loan outstanding balance at the end of the 2nd year, we need to determine the amount of principal repaid and subtract it from the original loan amount.

Each year, the borrower makes equal payments, so each payment would be P60,000 divided by 4, which is P15,000. However, each payment also includes interest. The interest on the outstanding loan balance at the beginning of the 2nd year is 15 percent of P60,000, which is P9,000.

The amount of principal repaid in the 2nd year is the total payment of P15,000 minus the interest of P9,000, which is P6,000.

Therefore, at the end of the 2nd year, the outstanding loan balance would be the original loan amount of P60,000 minus the principal repaid in the 2nd year, which is P60,000 - P6,000 = P54,000.

Answer: 215π

Step-by-step explanation:

If you think of the entire thing as two circles, it makes the problem a lot easier. If we were to find the area of the white "circle" and subtract it from the blue "circle", we would get the area of the ring. First, use the outer radius to find the area of this circle:

\(Area=\pi r^2\)

\(Area=\pi (24)^2=576\pi\)

Now find the area of the inner circle:

\(Area=\pi r^2\)

\(Area=\pi (19)^2=361\pi\)

Subtract the area of the inner circle from the area of the outer circle:

\(576\pi -361\pi =215\pi\)

The activity ratio in the value stream measures the efficiency of the production process by evaluating the ratio of value-added activities to non-value-added activities.

The activity ratio is a performance metric used in value stream mapping, which is a lean management tool for analyzing and improving the flow of materials and information in a production process.

It focuses on distinguishing value-added activities, which directly contribute to meeting customer requirements, from non-value-added activities, which do not add value but consume resources and time.

By calculating the activity ratio, organizations can assess the proportion of time and resources spent on value-added activities versus non-value-added activities.

A higher activity ratio indicates that a greater portion of resources is dedicated to value-added activities, indicating improved efficiency and reduced waste.

Conversely, a lower activity ratio suggests a higher proportion of resources being utilized for non-value-added activities, indicating potential areas for improvement and waste reduction.

The activity ratio serves as a valuable diagnostic tool for organizations to identify process inefficiencies, bottlenecks, and areas for improvement. By analyzing the activity ratio, organizations can streamline their processes, eliminate waste, and optimize resource allocation to enhance overall productivity and customer value.

The capital letter H has 2 reflectional symmetry and 2 rotational symmetry.

A figure has reflectional symmetry if it can be reflected across a line and still look the same. For the capital letter H, there is two lines of symmetry, which is the vertical line and horizontal line that divides the letter into two equal halves. Reflecting the letter across this line produces the same letter. So, the H has only 2 reflectional symmetries.

A figure has rotational symmetry if it can be rotated by some angle and still look the same. For the capital letter H, if we rotate it 180 degrees and 360 degrees about the center point of the letter, it will look the same. There is no other angle of rotation that produces the same letter. Therefore, the H has only 2 rotational symmetries.

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%

Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.
