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."

What is the product? assume x>0 (√3x + √5) (√15x +2√30

Answers

The first step for solving this expression is to multiply the parenthesis.
$√(45) x^(2) + 2√(90) x + √(75)x + 2√(150)$
Simplify the first radical.
$3√(5) x^(2) + 2√(90) x + √(75)x + 2√(150)$
Simplify the second radical.
$3√(5) x^(2) + 2X3√(10) x + √(75)x + 2√(150)$
Simplify the third radical.
$3√(5) x^(2) + 2X3√(10) x + 5√(3)x + 2√(150)$
Simplify the final radical.
$3√(5) x^(2) + 2X3√(10) x + 5√(3)x + 10√(6)$
Lastly,, calculate the product of 2 × 3 $√(10)$ x to get your final answer.
$3√(5) x^(2) + 6√(10) x + 5√(3)x + 10√(6)$

Sue subtracted 2.9 from 20.9 and got 1.8. Explain why this is not reasonable

Answers

because it is way to low even looking at it u can tell that it will still be in double diets

-- 20.9 is roughly 30.

-- 2.9 is roughly 3.

-- If Sue started with 30 and subtracted 3 from it, she would have 27.

-- 1.8 is nowhere near 27. It's not a reasonable answer.

(Actually, 20.9 - 2.9 = 18 . So you can see where maybe she got her
digits from, but she made some kind of bad mistake in handling them.)

Translate the phrase into a math expression.15 divided by a number, then decreased by 2

A.
(15 ÷ n) + 2

B.
(15 ÷ n) – 2

C.
15 ÷ (n – 2)

D.
15 ÷ (n + 2)

Answers

B. (15/n) – 2

Because you have to divide the 15 and the number first then "decrease" it by 2
