The side length of the square is 2*((8/2)^.5) = 4cm
The area is 4^2 = 16 cm

See the attached picture. The parts labeled a and b are both the same length since this is a square. And each of them is half of the side length of the square. We can find the length of a and b using the Pythagorean theorem because the 8cm is a hypotenuse of a right triangle. So we find a, and multiply by 2 to get the square side length. Then we square that to get the square area.

Graph: g(x)=5cos((\pi )/(2)x-(3\pi )/(2))-2
Tatiana [17]

g(x)=5cos((\pi )/(2)x-(3\pi )/(2))-2

generate by:  Amplitude:5    Period:4

                      Phase shift:(3 to the right)    Vertical shift:-2

x=3,g(x)= 3

x=4,g(x)= -2

x=5,g(x)= -5

x=6,g(x)= -2

x=7,g(x)= 3

the graph is like cos(x)

Is 1/8 less than 1/6?
trasher [3.6K]
1/8 or 1/6 
which is greater 

1) Lets make the fraction into a percent 
1/8 ⇒ 1 ÷ 8 =  0.125 
0.125 x 100 = 12.5%

1/6 ⇒ 1 ÷ 6 = 0.16....
0.16.. x 100 = 16.6.. = 16.7%

1/8 is bigger since it is closer to 0. 

Hope this helps
