The following figure is made of six semicircles with the same diameter, and of four congruent equilateral triangles represented

Oxana [17]

6 semicircles = 3 circles

The formula of the area of a equilateral triangle:

$A_\triangle=\dfrac{a^2\sqrt3}{4}$

We have a = |AE| = 3cm. Substitute:

$A_\triangle=\dfrac{3^2\sqrt3}{4}=\dfrac{9\sqrt3}{4}\ cm^2$

The formula of the area of a circle:

$A_O=\pi r^2$

We have 2r = |AE| =3cm → r = 1.5cm. Substitute:

$A_O=\pi\cdot1.5^2=2.25\pi\ cm^2$

The area of the figure:

$A=4A_\triangle+3A_O\\\\A=4\cdot\dfrac{9\sqrt3}{4}+3\cdot2.25\pi=9\sqrt3+6.75\pi=6\dfrac{3}{4}\pi+9\sqrt3\\\\=\dfrac{27}{4}\pi+\dfrac{36\sqrt3}{4}=\dfrac{9}{4}\cdot3\pi+\dfrac{9}{4}\cdot4\sqrt3=\dfrac{9}{4}(3\pi+4\sqrt3)\ cm^2$

2*log(y+5)=log 20-log 5

Ilia_Sergeevich [38]

Answer:

$y = - 3$

Step-by-step explanation:

$\frac{2 log_{10}(y + 5) }{2} = \frac{ log_{10}(20) }{2} - \frac{ log_{10}(5) }{2}$

$log_{10}(y + 5) = \frac{ log_{10}(20) }{2} - \frac{ log_{10}(5) }{2}$

$y + 5 = 2 \\ y = - 3$
