Initially, a spinner points west. Chenille moves it clockwise 2 1/4 revolutions and then counterclockwise 3 3/4 revolutions. In

Zigmanuir [339]

Answer: East

Step-by-step explanation:

Given

A spinner initially pointing towards west is made to move $2\frac{1}{4}$ revolutions clockwise and $3\frac{3}{4}$ revolutions counterclockwise.

After one complete revolution pointer points at the same direction.

So, the net movement of the spinner is

$\Rightarrow 3\dfrac{3}{4}-2\dfrac{1}{4}\\\\\Rightarrow \dfrac{15}{4}-\dfrac{9}{4}\\\\\Rightarrow \dfrac{15-9}{4}\\\\\Rightarrow \dfrac{6}{4}\ \text{or}\ 1\dfrac{2}{4}\ \text{CCW}$

That is 1 and half-revolution counter clockwise

After 1 revolution, direction is same, but after half revolution it points towards east.

The final direction is east.

Simplify 2√2-√3<br> ---------------<br> √2+√3

serious [3.7K]

Step-by-step explanation:

$= \frac{2 \sqrt{2} - \sqrt{3} }{ \sqrt{2} + \sqrt{3} }$

$= \frac{2 \sqrt{2} - \sqrt{3} }{ \sqrt{2} + \sqrt{3} } \times \frac{ \sqrt{2} - \sqrt{3} }{ \sqrt{2} - \sqrt{3} }$

$= \frac{ 2( \sqrt{2} - \sqrt{3} )( \sqrt{2} - \sqrt{3} )}{ { \sqrt{2} }^{2} - { \sqrt{3} }^{2} }$

$= \frac{2(2 - \sqrt{6} - \sqrt{6} - 3) }{2 - 3}$

$= \frac{2( - 1 - 2 \sqrt{6} )}{ - 1}$

$= \frac{ - 2(1 + 2 \sqrt{6} )}{ - 1}$

$= 2(1 + 2 \sqrt{6} )$

$= 2 + 4 \sqrt{6}$
