In the trapezoid ABCD ( AB ∥ CD ) point M∈ AD , so that AM:MD=3:5. Line l ∥ AB and going trough point M intersects diagonal AC and leg BC at points P and N respectively. Find: BC:BN.
Please give Statement/Reasoning proof as well. THANK YOU PLEASEE
For the given Trapezoid ABCD the value of BC:BN is BC:BN=8:3.
What is Trapezoid?
A trapezoid is a quadrilateral in American and Canadian English that has at least one pair of parallel sides. A trapezium is the term used in British and other varieties of English. In Euclidean geometry, a trapezoid is invariably a convex quadrilateral. The trapezoid's parallel sides are referred to as its bases.
Given:
In the trapezoid ABCD ( AB ∥ CD ) point M∈ AD , so that AM:MD=3:5.
Line l ∥ AB and going trough point M intersects diagonal AC and leg BC at points P and N respectively.
We have to find BC:BN
ABCD is a trapezoid and there is a point m which belongs to AD such that AM:MD=3:5.Line "l" parallel to AB intersects the diagonal AC at p and BD at N.
Now, we know that the parallel lines divide the transversal into the segments with equal ratio, therefore, BN:NC=AM:MD
But, BC= BN+NC
Therefore, BC:BN = (BN + NC): BN
⇒ BC:BN = (3 + 5): 3
⇒ BC:BN = 8:3
Hence, for the given Trapezoid ABCD the value of BC:BN is BC:BN=8:3.

Let y = (5 +b)x-c be perpendicular to 8x + 12y = 40. What is the value of b?
The value of b is -11/2.
What is the slope of the equation?
The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).
To find the value of b, we need to find the slope of the given line and the line that is perpendicular to it.
The slope of the line 8x + 12y = 40 is -8/12 = -2/3.
The slope of a line that is perpendicular to this line is the negative reciprocal of -2/3, which is 3/-2 = -3/2.
The slope of the line y = (5 + b)x - c is 5 + b. Therefore, to find the value of b, we need to set 5 + b equal to -3/2:
5 + b = -3/2
b = -3/2 - 5
b = -11/2
Therefore, the value of b is -11/2.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. Probability informs us of the likelihood that an event will occur given enough trials.Probabilities can be expressed numerically by the number of desired outcomes, divided by the total number of outcomes, when dealing with experiments that are random and well-defined in a purely theoretical context (like flipping a coin).To learn more about probability, refer:

0) The sum of the first and second of three
consecutive even integers is 126. Find the
three even integers.
Answer:
The three consecutive even integers are 40, 42 and 44.
Step-by-step explanation:
Let the consecutive even integers be
x, (x + 2) and (x + 4)The sum of the first and second of three consecutive even integers is 126.
So,
x + (x + 2) + (x + 4) = 126
Open the brackets
x + x + 2 + x + 4 = 126
Combine like terms we get,
3x + 6 = 126
Subtract 6 from both sides we get,
3x + 6 - 6 = 126 - 6
3x = 120
Divide 3 from both sides we get,
3x/3 = 120/3
x = 40
The value of x is 40 and the the consecutive even integers are
x = 40
x + 2 = 40 + 2 = 42
x + 4 = 40 + 4 = 44
Thus, The three consecutive even integers are 40, 42 and 44.

what is the probability of having the first head at the k-th trial? what is the name of this random variable?
The probability of having the first head at the k-th trial is 1/2.
The formula for the binomial distribution of probability is shown below. It can be used to determine the likelihood of getting K heads out of N coin tosses.
[nC k]* [pk]* [qn-k]
p= probability of receiving a head and
q= probability of having a tail.
Both p and q are 1/2.
As a result, the equation is [f12n! * f! r! * (n-r)!]
If you obtain exactly r successes, you also get (n - r) failures at the same time.
qn - rpr = P(getting r successes and n - r failures) (since the n trials are independent) Using the product theorem
There is no mention of the challenges from which the results were attained. There are nCr methods for selecting successful trials among r trials. The remaining (n - r) trials should be failures once the r trials that were picked for successes have been chosen. These nCr methods are incompatible. P(obtaining exactly r successes) in each of these nCr methods equals qn - rpr.

A rocket is fired with an initial vertical velocity of 40 m/s from a launch pad 45 m high. Its height is given by the formula , where h is in meters and t is in seconds. How high does the rocket go? How much time is the rocket in flight?
The maximum height which the rocket attains is 80 m and the time taken by the rocket is 8 sec.
Given,
the following formula yields the height h,
h= -5t² + 40t +45
45m is the height of the launch pad.
We take the first derivative of the function h and then set it to zero to determine the height the rocket reaches.
h' = 0
-10t + 40 =0
-10t = -40
t = 4
Therefore, height reached by the rocket in time t = 4 is,
h= -5t² + 40t +45
= -5(4)² + 40(4) + 45
=125 m
As a result, the rocket can reach:
125- 45
= 80 m
(To determine the real height the rocket travels, we have subtracted the height of the launch pad.)
The rocket takes twice as long to launch as it does to reach the peak.
t = 2*4 = 8 sec
Therefore,
the rocket goes 80 meters in height
the rocket's flight time is 8 seconds.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
As, Maximum miles driven=highest consumption per gallon × Maximum
gallons
where;
Maximum miles driven per person=64 mile
Maximum miles driven = 64×4

So, highest consumption =24.56 miles per gallon
let the Maximum gallons needed be x

Distance Formula:
d=√√(x₂-x₁)² + (y₁ - y₁)²
The distance between the two points is 2√10
Distance between two points:
The formula for the distance between two points (x₁, y₁) and (x₂, y₂) is given by Distance = √ [(x₂-x₁)² + (y₁ - y₁)²]
This formula can be used to find the length of a line whose endpoints are (x₁, y₁) and (x₂, y₂)
Here we have
The endpoints of the line are (1, 2) and (7, 4)
As we know d =√ [(x₂-x₁)² + (y₁ - y₁)²]
Take (x₁, y₁) = (1, 2) and (x₂, y₂) = (7, 4)
By the given formula,
Distance of line = √ [(7 - 1)² + (4 - 2)²]
