How is it possible to simplify 2 divided by (the square root of 6)? My calculator says that it is equal to (the square root of 6
Sauron [17]

Answer:

\boxed{\frac{\sqrt{6}}{3}}

Step-by-step explanation:

Multiply the fraction by \frac{\sqrt{6}}{\sqrt{6}}

\frac{2}{\sqrt{6}} \times \frac{\sqrt{6}}{\sqrt{6}} = \frac{2\sqrt{6}}{6}\\

Cancel the 2s

\frac{2\sqrt{6}}{6}= \frac{\sqrt{6}}{3}

∴ \boxed{\frac{2}{\sqrt{6}} = \frac{\sqrt{6}}{3}}

Write the equation of the piecewise function ƒ that is represented by its graph.
igomit [66]

Answer:

\left \{ {{f(x)=2;\text{ For }0\leq x1}} \right.

Step-by-step explanation:

We have been given graph of a piece-wise function. We are asked to write the equation for the given piece-wise function.

We can see that for x values greater than or equal to 0 and less than 1, the function is a line.

We can see that our given line is a horizontal line, so it will be in form y=C intersecting y-axis at (0,C).

The given crosses y-axis at (0,2), therefore, its equation would be y=2.

We can see that for x values greater than 1, the graph is a reflected and shifted square root function.

The square root function is reflected across x-axis and has a vertex at (1,1), therefore, our function for second part would be y=-\sqrt{x-1}+1.

The function is not defined at x=1 and it can a jump continuity.

Therefore, our required piece-wise function would be:

\left \{ {{f(x)=2;\text{ For }0\leq x1}} \right.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 100 miles per
storchak [24]

Solving for the elapsed time

distance traveled = (speed of first train + speed of second train) * elapsed time

280 miles = (95 mph + 105 mph) * elapsed time

280 miles = 200 mph * elapsed time

elapsed time = 280 miles / 200 mph

elapsed time = 1.4 hours

elapsed time = 1 hour and 24 minutes

It will take 1 hour and 24 minutes for the two trains to be 280 miles apart.
