Answer:

see explanation

Step-by-step explanation:

A cube has 6 congruent square faces

The area of 1 face = $\frac{2}{3}$ × $\frac{2}{3}$ = $\frac{4}{9}$

Multiply by 6 to obtain surface area of cube

surface area = 6 × $\frac{4}{9}$ = $\frac{24}{9}$ = $\frac{8}{3}$ units²

$e ^{2x} = ln5$

Solve for the real domain

$e ^{2x} = ln(5)$

if $f(x) =g(x),$ then $ln(f(x))= ln(g(x))$

$ln(e ^{2x} ) = ln(ln(5))$

Solve : $ln(e ^{2x} ) = ln(ln(5))$

use the logarithmic definition :

$ln(e^{f(x)} ) = f(x)$

$ln(e^{2x} ) = 2x$

$2x=ln(ln(5))$

Divide both sides by 2 :

$\frac{2x}{2} = \frac{ln(ln(5))}{2}$

$x= \frac{ln(ln(5))}{2}$

hope this helps!

How many sides does a regular polygon have, if each exterior angle measures 60?

DaniilM [7]

In a regular polygon, each exterior angle equals each central angle.
central angle = 360 / #sides
#sides = 360 / central angle
#sides = 360 / 60
#sides = 6

Pls help!! will give brainliest, thx, and 5star

nikdorinn [45]

Answer:

178

Step-by-step explanation:

The area of the rectangle is 6x25=150.

The area of the two semicircles on the sides is equal to the area of one circle with a radius of 3, so the area is $3\pi ^{2}$ which is approximately 28.27.

150+28.27=178.27
