Answer:

Step-by-step explanation:

√(x - 6) > 0, because √(x - 6) is in denominator.

√(x - 6) >0

(x - 6)>0

x > 6, so domain is (6, ∞). This is C. or D.

1/√(x - 6) cannot be negative because 1 >0, and √(x - 6) ≥0.

So,range cannot have negative values. And the answer is D.

Which expressions are equivilant to 6^16?

belka [17]

The expressions which are equivalent to 6¹⁶ are

$(6^{8}) ^{2}$

$(6^{-2}) ^{\times -8}$

and $(6^{-4}) ^{\times -4}$

<h3>Equivalent expressions </h3>

From the question, we are to determine which of the given expressions are equivalent to 6¹⁶

From one of the laws of indices, we have that

$x^{y\times z} = (x^{y})^{z}$

The given expression, 6¹⁶, can be expressed as

$6^{8\times 2}$

$6^{-2\times -8}$

$6^{-4\times -4}$

Then,

$6^{8\times 2}= (6^{8}) ^{2}$

$6^{-2\times -8}= (6^{-2}) ^{\times -8}$

$6^{-4\times -4}= (6^{-4}) ^{\times -4}$

Hence, the expressions which are equivalent to 6¹⁶ are

$(6^{8}) ^{2}$

$(6^{-2}) ^{\times -8}$

and $(6^{-4}) ^{\times -4}$

A bag has 5 red marbles, 4 blue marbles, 8 green marbles, and 3 yellow

kozerog [31]

<u>Answer:</u>

40% of the total marbles are green.

<u>Step-by-step explanation:</u>

Percentage: Green marbles/Total marbles

=> 8/5 + 4 + 8 + 3
=> 8/20

<u>Percentage formula:</u> $\frac{a}{b} (100)$ <u />

=> 8/20 x 100
=> 8 x 5
=> 40

Hence, 40% of the total marbles are green.

Hoped this helped.
