Which is a factor of 144 - 49x²?<br> O 12-7x²<br> O 72-7x²<br> O 12-7x<br> O 72 + 7x

lisabon 2012 [21]

Answer: C: 12-7x

Step-by-step explanation:

This expression is a good example of the difference of two squares, as 144 is the square of 12, while 49x² is the square of 7x.

Any difference of two squares $a^2-b^2$ can be factored into the sum of their square roots times the difference of their square roots $(a+b)(a-b)$ .

Let's factor our expression.

$144-49x^2=(12+7x)(12-7x)$

Out of all the options given, only $12-7x$ is a factor. Hence, option C is correct.

Compute the missing data in the table for the following exponential function f (x) = (one-fourth) Superscript x.

aliina [53]

Answer:

$F(4) = \frac {1}{256}$

Step-by-step explanation:

Given the following mathematical function;

$F(x) = \frac {1}{4^{x}}$

<u>When x = 1</u>

$F(1) = \frac {1}{4^{1}}$

$F(1) = \frac {1}{4}$

<u>When x = 2</u>

$F(2) = \frac {1}{4^{2}}$

$F(2) = \frac {1}{4*4}$

$F(2) = \frac {1}{16}$

<u>When x = 3</u>

$F(3) = \frac {1}{4^{3}}$

$F(3) = \frac {1}{4*4*4}$

$F(3) = \frac {1}{4*4*4}$

<u>When x = 4</u>

$F(4) = \frac {1}{4^{4}}$

$F(4) = \frac {1}{4*4*4*4}$

$F(4) = \frac {1}{256}$

<u>When x = 5</u>

$F(5) = \frac {1}{4^{5}}$

$F(5) = \frac {1}{4*4*4*4*4}$

$F(5) = \frac {1}{1024}$
