1 answer:

4 0

ANSWER

$256 {x}^{4}$

EXPLANATION

The given expression is

${(4x)}^{4}$

Recall that,

${(ab)}^{m}={(a}^{m}{b}^{m})$

We apply this property to get,

$= ( {4}^{4} {x}^{4} )$

This simplifies to,

$= 256 {x}^{4}$

Answer:

3 $\frac{1}{2}$

Step-by-step explanation:

Given

$\frac{\frac{1}{2} }{4}$ = $\frac{x}{28}$ ( cross- multiply )

4x = $\frac{1}{2}$ × 28 = 14 ( divide both sides by 4 )

x = $\frac{14}{4}$ = $\frac{7}{2}$ = 3 $\frac{1}{2}$

Round your answer to two decimal places.

vaieri [72.5K]

Answer:

<u>The correct answer is Hypotenuse = 3.61 units (Rounding to two decimal places)</u>

Step-by-step explanation:

We can use the Pythagoras theorem formula for solving this questions. It can be expressed symbolically as follows:

Hypotenuse² = First leg² + Second leg²

"The amount of units comprising the hypotenuse squared is equal to the addition of the measure of both legs squared."

Hypotenuse² = First leg² + Second leg²

Hypotenuse = √(First leg² + Second leg² )

Replacing with the real values:

Hypotenuse = √(3² + 2² )

Hypotenuse = √(9 + 4 )

Hypotenuse = √13

Hypotenuse = 3.60555

<u>Hypotenuse = 3.61 units (Rounding to two decimal places)</u>

A _________ is used to change one unit to another?

slamgirl [31]

Answer:

conversion factor

Step-by-step explanation:

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

Factor completely 8x5 2x4 4x2. Prime 2(4x5 x4 2x2) 2x(4x4 x3 2x) 2x2(4x3 x2 2).

Alecsey [184]

The complete factor of the expression $\rm 8x^5 + 2x^4 + 4x^2$ is $\rm 2x^{2} (4x^3 + x^2 + 2 )$ correct option is D.

<h3>What is a factorization?</h3>

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is $\rm 8x^5 + 2x^4 + 4x^2$ .

To solve the expression properly we have to take common (2x²). Then we have

$\rm 8x^5 + 2x^4 + 4x^2\\\\2x^{2} (4x^3 + x^2 + 2 )$

The factor is $\rm 2x^{2} (4x^3 + x^2 + 2 )$ .
