Answer: The correct option is, (B) SAS.

Step-by-step explanation: The SAS Postulate says that triangles are congruent if any pair of corresponding sides and their included angle are congruent.

The ratio of the volume of the cylinder to the volume of the prism is 4/π.

The volume of a cylinder is the number of unit cubes (cubes of unit length) that can be fit into it. It is the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it. The volume of a cylinder is measured in cubic units such as cm3, m3, in3, etc.

The volume of a square prism is referred to as the amount of space occupied by a 3-dimensional prism that has two congruent square bases and four rectangular faces are known as the volume of square prism. It is measured in cubic units. The volume of a prism is the product of the cross-sectional area and its length. The cross-sectional area is also known as the base area of the square prism.

We are given that a certain cylinder and square prism have equal lateral surface area.

Lateral surface area of cylinder = 2πrh

Lateral surface area of square prism = 4sH

So, 2πrh = 4sH

Also, the height of the cylinder is equal to the height of the prism.

So, h=H

Put in above equation:

2πrh = 4sh

⇒ πr = 2s

⇒ r/s = 2/π

The ratio of the volume of the cylinder to the volume of the prism

⇒ Volume of cylinder/ Volume of prism

⇒ πr²h/s²h

⇒ π(r/s)²

⇒ π(2/π)² ---- (From above)

⇒ 4/π

Thus, the ratio of the volume of the cylinder to the volume of the prism is 4/π.

Answer:

Q11: x = 3

Q12: x = -4

Step-by-step explanation:

Q11
We have the equation as
[tex]\:64^{2x\:+\:4}=16^{5x}[/tex]

Convert the bases in terms of the common base 4

64 = 16 x 4 = 4 x 4 x 4  = 4³

16 = 4 x 4 = 4²

Therefore the original equation becomes:
[tex]\mbox {\large 4^{3\left(2x+4\right)}=4^{2\cdot \:5x}}[/tex]

Since the bases are the same in this equation, the exponents must also be the same

Equation the two exponents we get

3(2x + 4) = 2·5x

==> 6x + 12 = 10x

Move 12 to the right side

6x = -12 + 10x

Move 10x to the left:

6x - 10x = -12

-4x = -12

x = -12/-4 = 3

Answer to Q11

Q12

We can solve this in a similar manner to Q12

27 = 3 x 3 x = 3³

9 = 3 x 3 = 3²

Plugging these in we get

[tex]\mbox {\large 27^x = 3^{3(x)} = 3^{3x}}[/tex]

[tex]\mbox {\large 9^ {(x - 2)} = 3^{2(x-2)} = 3^{2x -4} }\\\\[/tex]

Thus we get

[tex]\mbox {\large 3^{3x} = 3^{2x -4} }\\\\[/tex]

Equating the exponents we get

[tex]3x = 2x - 4\\\\3x - 2x = -4\\\\x = -4[/tex]

ANSWER to 12

y = C1e^(kx) is a valid solution to the equation.

To check that the given y is a solution to the equation, we must first substitute the given y into the given equation. We can do this by substituting the constants C1, C2, and k into the equation. We then move each side of the equation to the same side and simplify. This will result in an equation of 0 = 0, which confirms that the given y is a solution to the equation. In this case, the general solution to the second order differential equation dy dx + ky is yx) C1 cos(kx) + C2 sin(kx) or yx = D1 cosh(kx) + D2 sinh(kx). As such, the given y is a solution to the equation.

For the given equation, dy/dx = Py, with a constant k > 0, the given solution is y = C1e^(kx) or y = D1 cosh(kx) + D2 sinh(kx). To check that this is a valid solution, we can substitute the given solution into the equation and calculate dy/dx. If the result is equal to Py, then we can be sure that the given solution is a valid solution to the equation. For example, if we take the first solution y = C1e^(kx), then we can calculate dy/dx as dy/dx = C1ke^(kx) which is equal to Py = kC1e^(kx). We can see that the two sides are equal, so we can confirm that y = C1e^(kx) is a valid solution to the equation.

A patent is a form of intellectual property that gives an individual or organization the exclusive right to manufacture, use, and/or sell an invention for a set period of time.

The length of a patent varies by country, but generally lasts for 20 years from the date the patent is filed with the government. This period can be extended in certain cases if the patent office grants a patent term extension.

The formula for calculating the length of a patent is: Length of Patent = Initial 20 Year Period + Extension. The initial 20 year period starts from the filing date of the patent application and is the same for all countries. However, the length of the extension varies depending on the country and the circumstances of the patent. For example, some countries may offer a 5-year extension, while others may offer a 10-year extension.

The length of a patent must be carefully calculated so that the patent owner can maximize the benefits of the patent. By calculating the patent length and extension, the patent owner can ensure that they are able to take advantage of their exclusive right to the invention for the maximum amount of time possible.

The difference is that in an observational study, the researchers do not control treatment, and in an experiment, they do.

An experiment is a method used to verify or disprove a theory, as well as to determine something's effectiveness or likelihood.

An experiment vs an observational research differs fundamentally in that:

Members of a sample are measured or surveyed during an observational study without any attempt to manipulate them.

In an experiment, decisions are made under controlled conditions, subjects are divided into groups, and one group is given therapy while the other is left untreated. The main distinction between well-executed observational studies and experimental designs is that the replies of participants are unaffected, whereas in experiments, at least some participants are subjected to a treatment condition at random.

As a result, the researchers in an experiment control the therapy, but they do not in an observational study.

The function g(x) = (3x + 5) + 8 is a translation of 8 units upwards of f(x).

For a general function f(x), we define a vertical translation of N units as:

g(x) = f(x) + N

if N > 0, then the translation is upwards.

if N < 0, then the translation is downwards.

For a general function f(x), we define a horizontal translation of N units as:

g(x) = f(x) + N

if N > 0, then the translation is to the left.

if N < 0, then the translation is to the right.

Here we start at:

f(x) = 3x + 5

Function g(x) is:

g(x) = (3x + 5) + 8

g(x) = f(x) + 8

To calculate the number of ways to arrange the books on a shelf, we can use the formula for permutations.

The formula for permutations is  [tex]\frac{n!}{(n-r)!}[/tex]  

where:  n is the total number of items

              r is the number of items being selected.

a. In this case, there are 8 books total (3 blue + 3 green + 2 red), and we are arranging all of them.

so n= 8 and r = 8, the number of arrangements is

[tex]\frac{8!}{(8-8)!}[/tex] = 8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 =  40320

So the answer to (a) is 40320.

b. To calculate the number of arrangements if the books of the same color are grouped, we can consider each group as one item.

There are 3 groups (blue, green, red), and we are arranging those

so n = 8 and r = 3.

Hence, the number of arrangements is

[tex]\frac{8!}{(8-3)!}[/tex] = [tex]\frac{8!}{5!}[/tex] = [tex]\frac{8x7x6x5x4x3x2x1}{5x4x3x2x1}[/tex] = 336

If A limousine service has 15 cars available for rides: then the number of different collections C of 5 limousines are possible is 3003 .

To find the number of different collections C of five limousines, we can use combinations. A combination is a way to choose a subset of items from a larger set, without regard to order.

Let the number of Cadillac models n.

Then, 15 - 8 = 7 cars are Cadillacs. So, n = 7.

The number of different collections of 5 limousines from the 15 cars is given by the number of combinations of 5 items taken from a set of 15 items:

⇒ ¹⁵C₅ = 15!/(5!×(15 - 5)!) = 15!/(5!×10!) = 3003.

By using the tangent property of a circle, it has been proved that  ABC is isosceles

< ABC = 54°

What is a circle's tangent?

First, it's crucial to understand circles.

Every point on a circle keeps a set distance from the center point in a two-dimensional, rounded form known as a circle. The circle's radius is the fixed separation.

The tangent to a circle is the straight line that intersects the circle at any point.

Then Now

<ACB = <BAY = 72° ( angles in alternate segments)

<ABC + <ACB + < CAB = 180° { being sum of angles of triangle }

54° + 72° + <CAB = 180°

<CAB = 180° - 126°

<CAB = 54°

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The given function is f(x) = -5(4)x - 10

On solving the function it gives -

f(x) = -20x - 10

The graph for the function is plotted.

The end behavior of a function f(x) describes the behavior of the function as x approaches +∞ and as x approaches -∞.

Since the leading term of the polynomial (the term in the polynomial which contains the highest power of the variable) is -20x, the degree is 1, i.e. odd, and the leading coefficient is -20, i.e. negative.

This means that function f(x) approaches ∞ as x approaches -∞, and f(x) approaches -∞, as x approaches ∞.
