The circumference of the circle is approximately 24.492 yards.

what is circumference ?

Circumference is the distance around the edge of a circle or any other closed curve. It is the perimeter of a circle and is often denoted by the symbol "C". The circumference is a key measurement when working with circles, as it can help us calculate the radius, diameter, and area of the circle.

The formula for the circumference of a circle is:

C = 2πr

where "C" is the circumference, "π" (pi) is a mathematical constant approximately equal to 3.14, and "r" is the radius of the circle.

A circle does not have a perimeter as it is a two-dimensional shape. However, it has a circumference, which is the distance around the circle.

To find the circumference of a circle with a diameter of 7.8 yards and using π as 3.14, we can use the formula:

Circumference = π × Diameter

Circumference = 3.14 × 7.8 yards

Circumference = 24.492 yards (rounded to three decimal places)

Therefore, the circumference of the circle is approximately 24.492 yards.

Answer:

The missing angle is 65°

Step-by-step explanation:

For context, all triangles' angles will always add up to 180°. The outside angle of S is supplementary to the inside angle, so in order to find S:

180 - 153 = 27°

<TSU = 27°

S = 27°

U = 88°

As mentioned before, angles of triangles will add up to 180. In order to find the missing angle (?) we will add the other two sides and subtract them from 180.

27 + 88 = 115

180 - 115 = 65°

Using Standard deviation, approximately, 95% of the area under the normal curve falls between 2 standard deviations.

The area under a normal curve represents the total probability of an event occurring for a normally distributed random variable.

A normal distribution is a bell-shaped curve that describes a continuous probability distribution of a variable, where most values cluster around the mean, and the curve tapers off symmetrically on both sides.

The total area under the normal curve is equal to 1 or 100%, which means that the probability of all possible outcomes adds up to 1 or 100%.

The Empirical Rule states that:

Direct labor efficiency variance = $6,100 F.

Given that

Standard labor-hours per unit of output     8.5 hours

Standard labor rate                                     $12.30 per hour

Standard labor hours allowed                          6,800 hours (800 units *                                         8.5 hours allowed)

The following data pertain to operations concerning the product for the last month:

Actual hours worked  6,300 hours

Actual total labor cost  $74,970

Actual output                  800 units

We can determine the labor efficiency variance using the following equation:

1. Direct labor efficiency variance = (Standard hours allowed - Actual labor hours) * Standard rate

2. Direct labor efficiency variance = (6,800 hours - 6,300 hours) * $12.20

3. Direct labor efficiency variance = $6,100 F

The variance is favorable as the actual labor hours used are less than the standard hours allowed.

Hence the answer is Direct labor efficiency variance = $6,100 F.

The angle between the 5cm and 7cm sides to the nearest degree should measure approximately 71 degrees.

To construct a triangle with sides 7cm, 5cm and 6cm, start by drawing a straight line of 7cm length using the ruler. Next, use the compasses to draw an arc from one end of the line, with a radius of 5cm. Then, draw another arc from the same point of the line, with a radius of 6cm. Where the arcs intersect, draw a straight line connecting them to complete the triangle.

To measure the size of the angle between the 5cm and 7cm sides, use the compasses to draw a small arc from the vertex of the angle, and measure the angle using the ruler. To ensure accuracy, divide the angle into smaller, easier-to-measure angles. Repeat the process until the angle is measured to the nearest degree. In this case, the angle between the sides of 5cm and 7cm is approximately 71 degrees.

The given transfer function G(s) = 2/((s+1)(s+4)) has two poles at s = -1 and s = -4, a gain of 1/2 when s = 0, and it is a type zero system.

The given transfer function is G(s) = 2/((s+1)(s+4)).

To understand the properties of this transfer function, let's break it down:

Zeros: The zeros of a transfer function are the values of s for which the numerator becomes zero. In this case, the numerator is 2, which does not have any zeros.

Poles: The poles of a transfer function are the values of s for which the denominator becomes zero. In this case, the denominator is (s+1)(s+4), which becomes zero when s = -1 and s = -4.

Gain: The gain of the transfer function is the value of the transfer function when s is zero. In this case, when s = 0, the transfer function becomes G(0) = 2/((0+1)(0+4)) = 1/2.

Type: The type of a transfer function refers to the number of integrators in the system. To determine the type, we count the number of poles at the origin (s = 0). In this case, there are no poles at the origin, so the type of the transfer function is zero.

Overall, the given transfer function G(s) = 2/((s+1)(s+4)) has two poles at s = -1 and s = -4, a gain of 1/2 when s = 0, and it is a type zero system.

Yes, snow and "cold" weather are independent events. The probability of snow and a "cold" day is 15.

Based on the given probabilities, we can determine if snow and "cold" weather are independent events. Independent events occur when the probability of both events happening together is equal to the product of their individual probabilities.

P(snow) = 0.30

P(cold) = 0.50

P(snow and cold) = 0.15

If snow and cold are independent, then P(snow and cold) = P(snow) * P(cold).

0.15 = 0.30 * 0.50

0.15 = 0.15

Since both sides of the equation are equal, snow and "cold" weather are independent events.

Answer:

Step-by-step explanation:

The conclusion is our that : ∠B and ∠C are congruent

i.e., ∠B ≅ ∠C

We have the following:

A △ABC with AB ≅ AC

Since AB ≅ AC implies AB=AC.

The lengths of sides A B and A C are congruent.

Our assumption is ∠B and ∠C are not congruent.

Then the measure of one angle is greater than the other and

It is also given that:

m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem.

and if m∠B < m∠C, then AC < AB by the same reason.  

As we know if in a triangle two sides are equal then the triangle becomes an isosceles triangle.

Since triangle is isosceles then the angles opposite to equal sides are equal i.e.,

if AB=AC then ∠B = ∠C in △ABC

which is contradiction to the assumption that ∠B and ∠C are not congruent.

Therefore, it can be concluded that

∠B and ∠C are congruent.

The stage at which a company outlines the general characteristics of the types of products it plans to develop is the concept development stage.

To outline the types of products they will develop, companies often engage in various activities. They may conduct market surveys, analyze competitor offerings, and gather feedback from potential customers. This information helps them identify market gaps and determine the unique value proposition their product can offer.

Moreover, during this stage, companies may create prototypes or mock-ups of the product to visualize its physical or digital form. This allows them to assess the feasibility, practicality, and potential market acceptance of their ideas. Iterative design processes, such as user testing and feedback loops, can further refine the product concept.

The outcome of the concept development stage is a comprehensive product concept that serves as a foundation for subsequent stages. This concept outlines the core features, benefits, and unique selling points of the new product. It also provides guidance for the subsequent stages of the new product development process, such as product design, testing, and commercialization.

Answer:

The solution to the given  is y(t) = -1/15, which is defined on the interval (-∞, ∞).

The initial-value problem given is dy/dt = 2(t-1)y2 with the initial condition y(0) = -1/15. The solution of this problem is y(t) = -1/15, which is a constant. This means that the solution is defined on the entire real line, which can be written in interval notation as (-∞, ∞).

To derive this solution, we can start by taking the antiderivative of both sides of the equation. Doing so yields \(∫dy/2(t-1)y2 = ∫dt\). Applying the integral law of substitution yields \(∫dy/y2 = ∫(2(t-1))dt\). Solving this integral yields y = -1/15 + c, where c is an arbitrary constant. Since the initial condition is y(0) = -1/15, we can set c = 0 to get the solution y(t) = -1/15. This means the solution is a constant, so the largest interval on which the solution is defined is (-∞, ∞).
