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.

0) The sum of the first and second of three
consecutive even integers is 126. Find the
three even integers.
Answers
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 modulus function?
Regardless of whether a number is positive or negative, the modulus function, also known as the absolute value function, determines its magnitude. No matter what the number or variable, it always returns a non-negative value. The expression y = |x| or f(x) = |x|, where f: R (0,) and x R, denotes a modulus function.
When x is a real number, then |x| is its modulus. f(x) will have the same value as x if x is not negative. If x is negative, then f(x) will have the magnitude of x; if x is negative, then f(x) = -x. Here is a summary of the modulus function formula.
As we can see in the graph attached that the f(x) is zero at y=-8 and it is a modulus function so the graph will open upwards
but the graph is little shifted to y=-8 because the equation given to us is |x|-8 =g(x) so it will shift down according to the rule

Let y = (5 +b)x-c be perpendicular to 8x + 12y = 40. What is the value of b?
Answers
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.

In the continuous Efm=300+20m. series, if mean (x)=15+m and Find the number of terms N.
Answers
Answer:
the number of terms N in the series is approximately 8.57, which is approximately equal to 9.
Step-by-step explanation:
The mean of a series is calculated by taking the sum of all the terms in the series and dividing it by the number of terms. In this case, the mean of the continuous series Efm=300+20m is given as x=15+m.
To find the number of terms N in the series, we can use the formula for the mean to solve for N. The formula for the mean is:
mean = sum of terms / number of terms
Substituting the given values, we get:
15+m = (300+20m) / N
We can then multiply both sides of the equation by N to isolate the sum of terms:
(15+m) * N = 300+20m
This simplifies to:
15N + mN = 300 + 20m
We can then combine like terms to get:
(15+20)N = 300
35N = 300
Dividing both sides by 35, we get:
N = 300/35
N = 8.57
