Answer:

C the 12th root of (8^x)

Step-by-step explanation:

This becomes 8 ^ x/4  ^ 1/3

We know that a^b^c = a^ (c*c)

8 ^(x/12)

Your answer would be \sqrt[12]{8}^{2}.

Approaching this problem would be easier by converting the cube root of 8 to 8 to the power of 1/3. Remember that when you take anything to the nth root, it is the same as taking something to the power of 1 / n.

Therefore, the equation becomes (x^{1/3} )^{\frac{1}{4}x }.

Now, to keep simplifying, recall that when you do n^{x^y}, it can become n^{x*y}.

This can be applied in this situation. You are taking 8 to the power of 1/3 to the power of 1/4x. Now, you can multiply the two "to the power of's" to get 8^{\frac{1}{12}x }. Applying the same logic, it becomes 8^{\frac{1}{12} *x}  = 8^{\frac{1}{12} ^x}.

Now, all you have to do is use the same logic as used in the very beginning. Raising something to the power of 1/12 can become taking it to the 12th root. So therefore, the equation would be \sqrt[12]{8}^{x}

Good luck!

Given the diagram below, what is cos(45*)? <br><br> A.<br><br><br> B.<br><br><br> C.<br><br><br> D.
alina1380 [7]

Answer:

The answer is option B

Step-by-step explanation:

To find cos 45° we must first find the adjacent and the hypotenuse

Let the adjacent be x

Let the hypotenuse be h

To find the adjacent we use tan

tan ∅ = opposite / adjacent

From the question

the opposite is 9

So we have

tan 45 = 9 / x

x tan 45 = 9

but tan 45 = 1

x = 9

Since we have the adjacent we use Pythagoras theorem to find the hypotenuse

That's

h² = 9² + 9²

h² = 81 + 81

h² = 162

h = √162

h = 9√2

Now use the formula for cosine

cos∅ = adjacent / hypotenuse

The adjacent is 9

The hypotenuse is 9√2

So we have

cos 45 = 9/9√2

We have the final answer as

<h3 /><h3>cos 45 = 1 / √2</h3>

Hope this helps you

fias goal was to raise $5000 to help protect the manatees.She raised $3500.What percent of her goal did she achieve?
Fed [463]

Hello from MrBillDoesMath!

Answer:  70%

Discussion:

    Goal = 5000

    Amount raised = 3500

    Percent of goal reached = ( 3500/5000) * 100 =

                                                 0.7 * 100 = 70

 

Thank you,
