The nth term is given by 2ⁿ-1.
The series looks like, 1, 3, 7, 15, 31, 63, 127, ...
Because all are a multiple of 2, you can factor out 2, 2(-x^2+x+2)=0
Answer:
[0.16316 , 0.27684]
Step-by-step explanation:
0.22 +/- 1.96(0.029)
0.22 +/- 0.05684
[0.16316 , 0.27684]
You have to use the Pythagorean theorem but there is a little twist here since a square has has equal sides. So:
x^2+x^2=8
2x^2=8
2/2x^2=8/2
x^2=4
√x^2=√4
x=2
The side of the square is 2.
So now the area of a square is:
Side×Side
2×2=4
The area of the square is 4 centimetres
