If f (x) = StartRoot x minus 3 EndRoot, which inequality can be used to find the domain of f(x)?

kap26 [50]

Given:

The function is:

$f(x)=\sqrt{x-3}$

To find:

The inequality that is used to find the domain of the given function.

Solution:

We have,

$f(x)=\sqrt{x-3}$

We know that the radical functions are defined for only positive values of radicand.

It means the given function is defined if the value of (x-3) is greater than or equal to 0.

$x-3\geq 0$

Adding 3 on both sides, we get

$x-3+3\geq 0+3$

$x\geq 3$

The inequality $x-3\geq 0$ is used to find the domain of the given function and the domain of the given function is $x\geq 3$ .

Therefore, the correct option is B.

The surface area of a cube is 294 cm2. Which statements are true about the same cube measured in square millimeters? Choose all

wlad13 [49]

To check whether the statements are correct, we need to convert cm to mm.

surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a

1 cm = 10 mm
7 cm = 70 mm

Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²

B. The number representing the surface area would increase.
E. The actual surface area would stay the same.
