Answer:

0.6 or \frac{3}{5}

Step-by-step explanation:

Using the Pythagorean theorem (a^{2} +b^{2} =c^{2}) we get that the hypotenuse is 5.

so the cos V is adjacent over the hypotenuse. so if adjacent is 3 and hypotenuse is 5, the answer is \frac{3}{5} which equals 0.6 in decimal form.

Which of the following is equivalent to x^-1/2<br><br>1) -1/2x <br>2) -√x<br>3) 1/√x<br>4) -1/2x
irina [24]

Answer:

Option (3) is correct.

Step-by-step explanation:

We need to find the expression that is equivalent to x^{-1/2}.

The property is : x^{-a}=\dfrac{1}{x^a}

Here, a = 1/2

So,

x^{-1/2}=\dfrac{1}{x^{1/2}}

We know that, x^{1/2}=\sqrt{x}

\dfrac{1}{x^{1/2}}=\dfrac{1}{\sqrt{x} }

So, x^{-1/2} is equivalent to \dfrac{1}{\sqrt{x} }

Hence, the correct option is (3).
