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.

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.

Step-by-step explanation:

A. (0, -8); y = -8; opens up will be the correct solution for the graph of given modulus  function g(x) = |x| - 8.

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

Answer:

The three consecutive even integers are 40, 42 and 44.

Step-by-step explanation:

Let the consecutive even integers be

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.

No, the estimate should be higher

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

                                     =256 miles

So, highest consumption =24.56 miles per gallon

let the Maximum gallons needed be x

256=24.56 x

24.56 x=256

x ≥ 256/24.56

the 96th term of the arithmetic sequence 3, -14, -25 is -1048.

An arithmetic sequence is an ordered set of numbers that have a common difference between each consecutive term.

The general form of an arithmetic sequence is

aₙ = a₁ + d(n-1)

where aₙ is the nth term, a₁ is the initial term, and d is the common difference.

Given that n =96, a₁=-3, and d = -11

Substituting these value in the above equation

a₉₆ = -3 - 11(96-1) = -3 - (11*95) = -3-1045 = -1048

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.

percentage, a relative value indicating hundredth parts of any quantity.

Given that a person saves 12.5% of his income.

The monthly income of the person is 10000.

We need to find how much he spend in a month.

Convert 12.5 % to the decimal value by dividing 12.5 by 100.

12.5/100=0.125

Now multiply 0.125 with 10000

0.125×10000

Equation : 200 = 15x + 5y + 120

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
