What is the square root 6n carried to the power of 2/3 in radical form
BaLLatris [955]

Answer: \sqrt[3]{6n}

Step-by-step explanation:

We have the following expression:

(\sqrt{6n})^{\frac{2}{3}}

Which can be written as follows:

((6n)^{\frac{1}{2}})^{\frac{2}{3}}

Multiplying the exponents:

(6n)^{\frac{1}{3}}

Writing in radical form we finally have the result:

\sqrt[3]{6n}

A raindrop falls at 200m per minute. how long will it take a raindrop to travel 6000m?
Kryger [21]
The first thing you should know is that by definition:
 d = v * t
 Where
 d: distance
 v: speed
 t: time
 We then have to clear the time:
 t = (d) / (v)
 Substituting the values:
 t = (6000) / (200)
 t = 30 minutes
 Answer: 
 It will take a raindrop to travel 6000m about: 
 t = 30 minutes

Can someone please explain composite events to me in layman's terms?
kykrilka [37]

Step-by-step explanation:

A simple event is one that can only happen in one way - in other words, it has a single outcome. If we consider our previous example of tossing a coin: we get one outcome that is a head or a tail. A compound event is more complex than a simple event, as it involves the probability of more than one outcome.

Which of the following equations does not represent a linear relationship between x and y
Ksenya-84 [330]

A linear relationship is an equation that has a constant slope

The equation that does not represent a linear relationship is (b) y = 2x^2 + 5x

<h3>How to determine the non-linear relationship</h3>

A linear equation can take any of the following forms:

y = mx + b

y - y1 = m(x - x1)

Ax + By = c

Any form different from the above forms is not a linear equation

Using the above format as a guide, the equation that does not represent a linear relationship is (b) y = 2x^2 + 5x
