What’s a reflection transformation

Answers

Answer:

A rigid transformation that flips preimage without changing size or shape just the angle over a specific line.

Step-by-step explanation:

"In mathematics, a reflection is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis or plane of reflection. The image of a figure by a reflection is its mirror image in the axis or plane of reflection."

"In geometry, a reflection is a type of rigid transformation in which the preimage is flipped across a line of reflection to create the image. Each point of the image is the same distance from the line as the preimage is, just on the opposite side of the line."

The formula for the area A of a trapezoid is A=1/2(b1+b2)h, where b1 and b2 represents the lengths of the bases and h represents the height. Which equation can be used to find the height of a trapezoid?A. h=2A-b1-b2
B. h=2A/b1+b2
C. h=A(b1+b2)/2
D. h=A-2/b1-b2

Answers

The answer:  [B]:  h = 2A / (b1 + b2) .
__________________________________________________________
Explanation:

Given:  A = (½) * (b1 + b2) * h ; 
________________________________
→Multiply EACH side of the equation by "2", to get rid of the fraction, "½";
____________________________________________________________
  → 2*A = 2 *  (½) * (b1 + b2) * h ; 

  → 2* A = 1 * (b1 + b2) * h ;
 
  → 2A =  (b1 + b2) * h ; 
____________________________
→ Now, divide EACH side of the equation by: "(b1 + b2)" ; to isolate "h" on one side of the equation; 
__________________________________________________________
  →   2A  / (b1 + b2) =  [(b1 + b2) * h] / (b1 + b2) ;

  →   2A  / (b1 + b2) =  h ; ↔ h = 2A / (b1 + b2) ; which corresponds to:
                                            "Answer choice: [B]" .

A box contains 3 plains pencils and 7 pens . A second box contains 6 color pencils and 2 crayons one item from each box is chosen at random. What is the probability that a pen from the first box and crayon from the second box are selected

Answers

Well to solve these type of question it is very easy to make a tree diagram and then solve them. How ever i have done it here for you.

So basically we have to get a pen from the first box so its probability is 7 / 10.

Similarly, we have to get a crayon from the second box so its probability is 2 / 8.

Now by counting principle we can multiply the two probabilities so 7/10 * 1/4 which becomes equal to 7/40.
