True or False?In Exercise,determine whether the statement is true or false given that f(x) = In x.if it is false,explain why or

kompoz [17]

Answer:

The given statement is false.

Step-by-step explanation:

We are given the following in the question:

$f(x) = \text{In } x$

The given statement is

$f(x - 2) = f(x) - f(2), x > 2$

Putting the values on the right side of the given statement

$f(x-2)\\=\text{ln }(x-2) \neq \text{ln }x - \text{ln }2$

Thus, the given statement is false.

This can be explained with the help of an example:

For x = 3

$f(x-2) = f(3-2) = f(1)\\=\text{ln }1 = 0\\f(x)-f(2)\\=\text{ln }3-\text{ln }2 \\=0.4054$

Factor Completely x^4-2x^2y^2+y^4

12345 [234]

<h3>Answer :</h3>

$\bf (x+y)^2(x-y)^2$

==============

<h3>Solving Steps:</h3>

===============

$\rightarrow \sf x^4-2x^2y^2+y^4$

<u>breakdown</u>

$\rightarrow \sf x^4-x^2y^2-x^2y^2+y^4$

<u>factor common term</u>

$\rightarrow \sf x^2(x^2-y^2)-y^2(x^2-y^2)$

<u>collect in groups</u>

$\rightarrow \sf (x^2-y^2)(x^2-y^2)$

<u>apply difference between two square method:</u> x² - y² = (x+ y)(x-y)

$\rightarrow \sf (x+y)(x-y) (x+y)(x-y)$

<u>simplify</u>

$\rightarrow \sf (x+y)^2(x-y)^2$

Compute 0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4)).

alexandr1967 [171]

The value of 0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4)) is -40

<h3>What are integers?</h3>

An integer is a whole number (not a fractional number) that can be positive, negative, or zero.

Given:

0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4))

= 0+5-10-15-20

=5-25-20

= -40

Hence, value of 0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4)) is 40.
