What is triangle ?

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.

Given,

x , y and z are exterior angles of triangle ABC.

So,

By angle sum property of triangle

Angles of

1 + 2 + 3 = 180

1 + z = 180

3 + y = 180

2 + x = 180

z + 180 = 1

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.

Answer:

s = 1.5d

where s = number of scarves knitted

d = number of days required to knit s scarves

Step-by-step explanation:

Let s represent the number of scarves knitted in 4 days

The direct variation relationship is s = kd where k = constant of proportionality

So k = s/d

For s = 6, d = 4

So k = 6/4 = 1.5

So the direct variation equation is s = 1.5d

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.

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

The time that Llyr arrives at Nuneaton, given that it is 6 minutes late, is 10 34.

Llyr's journey from Preston to Nuneaton took 114 minutes.

Kathy would not catch the 10 28 train to Milton Keynes.

Llyr is meant to arrive in Nuneaton at 10 28 but arrived 6 minutes later which is:

The time that the trip took is therefore:

= Arrival at Nuneaton - Departure at Llyr

= 10 34 - 08 40

= 1 hour 54 minutes

= 114 minutes

The time that Kathy would get back to the station is:

The area of the region bounded by the parabola is [tex]\frac {5}{12} $[/tex].

Area of the region bounded by y=f(x) and x axis between x=a and x=b is given by [tex]$\int_a^b f(x) d x$[/tex]. The coordinates of all the points mentioned are first calculated and then finally the area of required region OAC is calculated.

The area of the region bounded by the parabola y=[tex]5x^{2}[/tex].

The area that needs to be calculated is the area enclosed by OAC as shown in figure.

From the figure, it is clear that

Area of region OAC=area of region OAB-area of region ABC......(1) let us first calculate the equation of the tangent at(1,5).

⇒[tex]$\frac{d y}{d x}=10 x \Rightarrow \frac{d y}{d x}(1,5)=10$$[/tex]

Equation of tangent is y-5=10(x-1).

This tangent intercepts x axis at [tex]$x=\frac{-5}{10}+1=\frac{1}{2}$[/tex]  (Putting y=0 in equation of tangent)

Hence, coordinates of C is (0.5,0) and B is (1,0).

⇒BC=OB−OC⇒BC=1−0.5=0.5

The area of region ABC is [tex]$\frac{1}{2} * B C * A B=\frac{1}{2} * 0.5 * 5=\frac{5}{4}$[/tex]

Now area of region OAB is given by [tex]$\int_0^1 5 x^2 d x \Rightarrow\left[\frac{5}{3} x^3\right]_0^1=\frac{5}{3}$[/tex]

Area of region OAB is thus [tex]$\frac{5}{3}$[/tex]

Now using equation (1) area of region OAC [tex]=\frac{5}{3}-\frac{5}{4}=\frac{5}{12}$[/tex]

The area of region OAC is [tex]\frac {5}{12} $[/tex].

Therefore, the area of the region is [tex]\frac {5}{12} $[/tex].

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

in our second equation lets isolate x

x = 2y + 4

now lets plug this into our first equation

6(2y+4) + 2y = -4

12y + 24 + 2y =-4

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.

The distance from A to B is 355.42 feet.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

From the figure,

Tan 4 = PQ/853

PQ = tan 4 x 853

PQ = 0.07 x 853 _____(1)

Tan 7 = PQ/(853 - x)

PQ = tan 7 x (853 - x)

PQ = 0.12 x (853 - x) ______(2)

Now,

From (1) and (2) we get,

0.07 x 853 = 0.12 x (853 - x)

59.71 = 102.36 - 0.12x

0.12x = 102.36  - 59.71

For the function f(x) = -5(4)x - 10, the end behaviour signifies that [x→∞,f(x)→-∞] and [x→-∞,f(x)→∞].

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 ∞.

Therefore, the end behaviour is [x→∞,f(x)→-∞] and [x→-∞,f(x)→∞].

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

<BAY = 72°

< 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°
