Geo is
an=a1r^(n-1)
2nd term is 12
4th term is 4/3
a2=a1r^(2-1)=12
a2=a1r=12
a4=a1r^(4-1)=4/3
a4=a1r^3=4/3
we have
a1r=12 and a1r^3=4/3
(a1r^3)/(a1r)=r^2=(4/3)/12=1/9
1/9=r^2
sqrt oth sides
1/3=r
the common ratio is 1/3
Answer:
26.8<u>3</u>
Step-by-step explanation:
5/6=0.83333 repeating
Draw a square with 4 equal sides that are 6 inches long. Then draw a small square on a corner of your drawn square. A(x) = 36 - A^2
a being the area of the smaller square
A^2= area of a square.
