A transformation named T maps triangle XYZ to triangle X'Y'Z'. The transformation is a(n) _____.
wel

Answer:

The transformation is called Translation.

Step-by-step explanation:

We have different types of transformation:

Translation: A translation or slide is an isometry in which all points of a figure move the same distance and in the same direction.

Reflection: A reflection is an isometry in which the preimage and the image have opposite orientations. In other words, the image appears backwards.

Rotation: A rotation is an isometry in which a figure has been rotated or turned around a point called center of rotation.

Dilation: A dilation could be an enlargement or a reduction.

In Geometry, "Translation" simply means Moving without rotating, resizing or anything else, just moving.

To Translate a shape: Every point of the shape must move;

   the same distance

   in the same direction.

So, in this question XYZ translate to X^{'} Y^{'} Z^{'} since every point move in the same distance and same direction.

The proof for the product property of logarithms requires simplifying the expression logb(bx y) to x y. Which property is used t
masya89 [10]

You can use the properties of logarithm to derive the simplified form of the given expression.

The simplification of the given expression requires the given below properties of logarithm

  • log_a(b^c) = c \times log_a(b)\\\\
  • log_b(b) = 1

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

  • b = log_a(c)

Some properties of logarithm are:

log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})\\\\log_a(b^c) = c \times log_a(b)\\\\log_b(b) = 1

<h3>Using the above properties, to get to the simplified form of the given expression</h3>

The given expression is

log_b(b^{x+y})

Using the property log_a(b^c) = c \times log_a(b)\\\\, we get

log_b(b^{x+y}) = (x+y)\times log_b(b)

Using the property log_b(b) = 1, we get

log_b(b^{x+y}) = (x+y)\times log_b(b) = (x+y) \times 1 = x + y

Thus,

The simplification of the given expression requires the given below properties of logarithm

  • log_a(b^c) = c \times log_a(b)\\\\
  • log_b(b) = 1

7. What's the sum of 2/5 and 2/4?
NISA [10]

Step-by-step explanation:

2/5+2/4 (find common denominator)

The common denominator is 20

2/5 is 8/20 (multiply by 4)

2/4 is 10/20 (multiply by 5)

8/20+10/20 is 18/20

If you simplify 18/20 this would by 9/10 if you divide by 2

so the total is 18/20 or 9/10 simplified

Hope this helps!!!!

Have a nice day :)
