Which expression is equivalent to sqrt2x^5/18 ? Assume x>0.

qwelly [4]

Answer

$\frac{x^{2} \sqrt{x} }{3}$

Step-by-step explanation:

first off rt(2x^5) can be simplified as x^2 rt(2x) because we can break up x^5 into x^4 * x. x^4 is a perfect square so factor out a x^2.

the denominator $\sqrt{18}$ can be written as $3\sqrt{2}$ since the factors of 18 involve a perfect square of 9. 9*2 is 18 so factor out a 3.

the whole fraction :

$\frac{x^{2} \sqrt{2x} }{3\sqrt{2} }$

cancel out the $\sqrt{2}$ and you are left with $\frac{x^{2} \sqrt{x} }{3}$

leonid [27]

Answer:

$(1, -2)$

Step-by-step explanation:

Step 1: Set the second equation into the first

$x + (-2x) = -1$

$x - 2x = -1$

$-x / -1 = -1 / -1$

$x = 1$

Step 2: Solve the second equation

$y = -2(1)$

$y = -2$

Answer: $(1, -2)$

Answer:

(D) Pie chart

Step-by-step explanation:

The most appropriate method to represent the resulting data is the pie chart. This is because, in this sample, the variables are few and of nominal type.

Of the rest of the options, the only other that could be used is the histogram, since it can represent nominal variables with their corresponding frequency. The rest of the options have other uses not appropriate for this type of sample.
