The new coordinate of point (5,-4) after dilation by a scale factor of 33 centered at the origin is (165,-132)(165,132)
What is the scale factor?You must specify the extent of the shape's enlargement when describing one.
The scale factor is the ratio of two dimensions such that one figure is large and another is small.
Given the coordinate (5,-4),(5,-4)
If we apply a scale factor by 33 on any general coordinate (x,y)
Then,
x → 33x and y → 33y
Similarly
5 → 33(5) = 165
-4 → 33(-4) = -132
So the new coordinate will be (165,-132)(165,-132)
Same step apply once more for (5,-4) the coordinate of other is same
Hence "The new coordinate of point (5,-4)(5,-4) after dilation by a scale factor of 33 centered at the origin is (165,-132),(165,-132)

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.
Given the matrices A and B shown below, find A + B.

D. (-8, 0); x = -8; opens down
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

The number of minutes will it take him to mow the entire yard will be 50 minutes.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Dad mowed 60% of the yard in 30 minutes.
Let 'A' be the entire area of the lawn and 'x' be the total time to mow the entire lawn. Then 60% of the lawn is given as,
⇒ 60% of A
⇒ 0.60A
The ratio of the area of the lawn to time remains constant. Then the equation is given as,
0.60A / 30 = A / x
x = 30 / 0.60
x = 50 minutes

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.

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.

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.
