The diagonal of a square is x what is the perimeter of the square
RSB [31]

Answer:

2\sqrt{2} x

Step-by-step explanation:

The diagonal divides the square into 2 right angles with legs s and hypotenuse x

Using Pythagoras' identity on one of the right triangles, then

s² + s² = x²

2s² = x² ( divide both sides by 2 )

s² = \frac{x^2}{2} ( take the square root of both sides )

s = \sqrt{\frac{x^2}{2} } = \frac{x}{\sqrt{2} }

Thus

perimeter = 4s = 4 × \frac{x}{\sqrt{2} } = \frac{4x}{\sqrt{2} }

Multiply numerator/ denominator by \sqrt{2}

perimeter = \frac{4x\sqrt{2} }{2} = 2\sqrt{2} x

3cot^(2 )x-1=0<br><br> Pls Help
Elina [12.6K]

Answer:

x=\frac{\pi }{6} ,\frac{7\pi }{6}

Step-by-step explanation:

3*cot^2x-1=0\\\\3*cot^2x=1\\\\cot^2x=\frac{1}{3} \\\\cot(x)=\sqrt{\frac{1}{3} } \\\\cot(x)=\frac{1}{\sqrt{3} } \\\\\frac{1}{tan(x)}=\frac{1}{\sqrt{3} } \\\\tan(x)=\sqrt{3} \\

x=tan^-1(\sqrt{3})

It has to be in Quadrant 1  \frac{+}{+} =+ or 3 \frac{-}{-}=+ for positive.

x=\frac{\pi }{6} ,\frac{7\pi }{6}

Unless that incorrect due to tan(x) range is -\frac{\pi }{2} \leq x\leq \frac{\pi }{2}. Then the only answer is x=\frac{\pi }{6}

At a sports event, 1, 045 spectators will be
raketka [301]

Answer:

85n >/= 1,045

Step-by-step explanation:

85 people times n buses has to equal or exceed 1,045 people

85n is greater than or equal to 1,045

85n >/= 1, 045

n >/= 12.29

So, since n has to be greater than or equal to 12.29, and there is no 29/100ths of a bus, they would need 13 buses (in case there's a follow-up question)

Please lmk if you have questions.
