Perimeter is the distance around the edge of a shape. The algebraic sum of the length of each side is the perimeter of that shape. We have formulas available for the various shapes in geometry.

The perimeter of a square is expressed as 4l

The circumference of a circle = 2πr

This means that;

4l = 2πr

4l = 2× 3.142 × 2

4l = 12.57

divide both sides by 4

l = 12.57/4

l = 3.14 units(nearest hundredth)

therefore the value of the side length is 3.14 units

Step-by-step explanation:

Therefore, the perimeter of triangle ABC is 70 units.

A triangle is a polygon with three sides and three angles. It is one of the basic shapes in geometry and is formed by connecting three non-collinear points with straight line segments. Triangles can be classified based on the length of their sides or the measure of their angles. Some common types of triangles include equilateral triangles, isosceles triangles, scalene triangles, acute triangles, obtuse triangles, and right triangles. Triangles have many important properties and are used in many areas of mathematics and science, including trigonometry, geometry, and physics.

Here,

Since D and E are midpoints of the sides AB and AC, respectively, we know that DE is parallel to BC and that DE is half the length of BC. Similarly, we know that EF is parallel to AB and that EF is half the length of AB. Finally, we know that DF is parallel to AC and that DF is half the length of AC. Therefore, we can construct a parallelogram with sides BC and DE, and another parallelogram with sides AB and EF, as shown in the diagram below.

    A

    /\

   /  \

 E/____\F

Since DE is parallel to BC, we know that triangle ADE is similar to triangle ABC, and that the ratio of their side lengths is 1:2. Therefore, the length of BC is twice the length of DE, or 2*7=14 units.

Similarly, since EF is parallel to AB, we know that triangle AEF is similar to triangle ABC, and that the ratio of their side lengths is 1:2. Therefore, the length of AB is twice the length of EF, or 2*12=24 units.

Finally, since DF is parallel to AC, we know that triangle DFC is similar to triangle ABC, and that the ratio of their side lengths is 1:2. Therefore, the length of AC is twice the length of DF, or 2*16=32 units.

Therefore, the perimeter of triangle ABC is AB+BC+AC=24+14+32=70 units.

The number is 5 if two increased by a number is a dozen. In other words, the correct answer is 5 by solving equations.

Step 1: Write the given information as an equation. "Two increased by a number" can be represented as 2 + x, where x is the unknown number.

Step 2: Translate "Two increased by a number is a dozen" into an equation. The word "a dozen" refers to the number 12.

\(2 + x = 12.\)

Step 3: Solve the equation for x. To isolate x, subtract 2 from both sides of the equation:

\(2 + x - 2 = 12 - 2.\)

This simplifies to x = 10.

Step 4: Verify the solution. Substitute the value of x back into the original equation:

2 + 10 = 12.

This equation is true, so x = 10 is indeed the solution.

Answer: imaginary axis

Step-by-step explanation:

The correct function that describes the student's distance from the finish line after x minutes is f(x) = -1/4x + 10.

The correct function that describes the student's distance from the finish line after x minutes can be determined by analyzing the given information. We know that the student runs 1 kilometer every 4 minutes, and the race is a total of 10 kilometers.

Let's examine the options:

1. f(x) = 1/4x + 10

This function represents the distance covered by the student in x minutes, but it does not account for the fact that the total race distance is 10 kilometers.

2. f(x) = -1/10x + 4

This function has a negative coefficient for x, which would indicate that the student is getting farther away from the finish line as time progresses, which is not the case.

3. f(x) = 1/10 + 4

This function is a constant and does not change with time, so it cannot describe the student's distance from the finish line.

4. f(x) = -1/4x + 10

This function correctly represents the student's distance from the finish line. The negative coefficient for x indicates that the distance decreases as time progresses, and the constant term of 10 represents the initial distance from the finish line, which is 10 kilometers.

To solve the partial differential equation (PDE) Uyy + uy = 1, we can use the method of separation of variables.

Assuming u(x, y) can be written as a product of two functions, u(x, y) = X(x)Y(y), we substitute this into the PDE and separate the variables:

Y''(y)X(x) + Y'(y)X(x) = 1

Dividing both sides by X(x)Y(y), we get:

Y''(y)/Y(y) + Y'(y)/Y(y) = 1/X(x)

Since the left side depends only on y and the right side depends only on x, both sides must be equal to a constant. Let's denote this constant by -λ²:

Y''(y)/Y(y) + Y'(y)/Y(y) = -λ²

X''(x)/X(x) = λ²

Solving the two ordinary differential equations (ODEs) separately, we find the general solutions for Y(y) and X(x). Then, combining these solutions, we obtain the general solution u(x, y).

To solve the PDE Uxy - uy = 2, we can use a similar approach. Assume u(x, y) = X(x)Y(y), and substitute it into the PDE:

X'(x)Y'(y) - Y'(y)X(x) = 2

Dividing both sides by X(x)Y(y), we get:

X'(x)/X(x) - Y'(y)/Y(y) = 2/(X(x)Y(y))

Again, since the left side depends only on x and the right side depends only on y, both sides must be equal to a constant. Let's denote this constant by λ:

X'(x)/X(x) = λ

Y'(y)/Y(y) = -λ

Solving these ODEs separately, we find the general solutions for X(x) and Y(y). Combining these solutions gives us the general solution u(x, y).

The probability that the balls are drawn from the first urn is 0.99.

The given problem provides information on two urns. In the first urn, 70% of the balls are red, and 30% are blue, while in the second urn, 70% of the balls are blue, and 30% are red. From one of the urns, 12 balls are randomly drawn, out of which 8 are red, and 4 are blue.

We need to determine the probability that the balls are drawn from the first urn.

Let A be the event that the balls are drawn from the first urn. The probability of selecting urn 1 is given by P(A). Out of the 12 balls drawn, 8 are red and 4 are blue. Hence, we can write P(RRBBRRRRRRRR) = P(A) x P(8 red balls and 4 blue balls are drawn | A).

The probability of selecting either urn 1 or urn 2 is 0.5, which is represented as P(A) = P(B). Therefore, P(RRBBRRRRRRRR) = 0.5 x (0.7)^8 x (0.3)^4 = 0.00424.

Let B be the event that the balls are drawn from the second urn. The probability of selecting urn 2 is given by P(B). Out of the 12 balls drawn, 4 are red and 8 are blue. Hence, we can write P(BBRRBBBBBBBB) = P(B) x P(4 red balls and 8 blue balls are drawn | B).

Therefore, P(BBRRBBBBBBBB) = 0.5 x (0.3)^4 x (0.7)^8 = 0.00043.

The probability that the balls are drawn from the first urn is given by P(A | RRBBRRRRRRRR) = P(A) x P(RRBBRRRRRRRR) / [P(A) x P(RRBBRRRRRRRR) + P(B) x P(BBRRBBBBBBBB)].

Substituting the values, we get P(A | RRBBRRRRRRRR) = 0.5 x 0.00424 / [0.5 x 0.00424 + 0.5 x 0.00043] = 0.989 which is approximately 0.99.

To find a power series solution for the given differential equation, we start by assuming a power series solution of the form:

y(x) = Σ C_k * x^k

where C_k are constants to be determined, and Σ represents the summation symbol.

First, let's find the derivative of y(x):

y'(x) = Σ k * C_k * x^(k-1)

Next, substitute y(x) and y'(x) into the differential equation:

y' - 4y = Σ k * C_k * x^(k-1) - 4 * Σ C_k * x^k = 0

Now, we can rearrange the terms and combine the series:

Σ (k * C_k - 4 * C_k) * x^k = 0

This equation must hold for all values of x, so the coefficients of each term must be zero:

k * C_k - 4 * C_k = 0

Simplifying the equation, we have:

(k - 4) * C_k = 0

This equation tells us that either k - 4 = 0 or C_k = 0. Since we are looking for a non-trivial solution, we set k - 4 = 0, which gives k = 4.

Now, let's determine the value of C_4. Substituting k = 4 into the power series solution, we have:

y(x) = C_4 * x^4

Since we have not been given any initial conditions, we cannot determine the exact value of C_4. However, the coefficient C_4 represents the term with the highest power of x, and it corresponds to the constant of integration in the solution.

The radius of convergence of the resulting series is P = ∞, which means the power series solution converges for all values of x.

By comparing the series with well-known series, we can identify that the series solution in terms of familiar elementary functions is:

y(x) = C_4 * e^(4x)

Therefore, the power series solution to the given differential equation is y(x) = C_4 * e^(4x), where C_4 is an arbitrary constant.
