Simplify: −√16x^2 , when x<0

Savatey [412]

Answer:

$-4|x|$

Step-by-step explanation:

To simplify :

$-\sqrt{16x^2}$ , when $x$

In order to simplify the given expression we will take the square root of the term inside the root.

The term in the square root are perfect squares (square of an integer), so, we can write them in square of the numbers.

⇒ $-\sqrt{(\pm4x)^2}$ [As $(\pm4x)^2=16x^2$ ]

On taking square root the square gets removed. So, we have,

⇒ $-(\pm4x)$

⇒ $-4|x|$

Since $x$ , so the value would be negative.

So, simplified answer is

$-4|x|$ (Answer)

A hot air balloon holds 1,592 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic

yuradex [85]

Answer: 285.2 kg

Step-by-step explanation:

Given

The volume of helium in the balloon is $V=1592\ m^3$

The density of the helium is $\rho =0.1785\ kg/m^3$

Mass of the helium gas is given by the product of density and volume

$\Rightarrow M=\rho \cdot V\\\Rightarrow M=0.1785\times 1592\\\Rightarrow M=285.2\ kg$

Thus, the mass of gas is 285.2 kg
