DaniilM [7]

Just told you : first know by heart remarkable identities !

Then apply :

4x²-12x = -9

4x²-12x +9 =0

(2x-3)² = 0

(2x-3) (2x-3) = 0

Now you have a double solution :

2x-3 = 0

and 2x -3 = 0

I let you try !

A region is bounded by semicircular arcs constructed on the side of a square whose sides measure 2/\pi, as shown. What is the pe

Paladinen [302]

Answer:

Step-by-step explanation:

The perimeter of the region is equal to the sum of the perimeter of the four semicircular arc. Since the semicircular arcs have the same measure, therefore:

Perimeter of region = 4 × Perimeter of semicircular arc.

The side of the square = diameter of the semicircle = 2/π.

The radius of semicircle = diameter/2 = $\frac{2/\pi}{2} =\frac{1}{\pi}$

The perimeter of a semicircle = perimeter of a circle ÷ 2

$Perimeter\ of \ semicircle = \frac{perimeter\ of\ circle}{2}=\frac{2\pi r}{2}=\frac{2\pi (\frac{1}{\pi} )}{2} =1\\ Perimeter\ of\ region = 4*Perimeter\ of \ semicircle=4*1=4\$
