A) New branch in:
2nd stage=2
3rd stage=4
4th stage=8
which can be listed as 2,4,8,...
Here,
2nd term/1st term=4/2=2
3rd term/2nd term=8/4=2
Since common ratio is 2, the given sequence is geometric sequence.
b) The required function is,
B(n)=2^(n-1)
{just put n=1,2,3.. here to check if it gives accurate no of branches in each step or not}
where n is stage number
c)Using above function to calculate total no of branches growing out in the 8th stage,
B(8)=2^(8-1)=2^7=128
3/5 is 12/20 simplified. :)
1. Find the greatest common factor of 12 and 20 which is 4.
2. Divide 12 by 4 and 20 by 4.
3. 12/4=3 and 20/4=5
4. 3/5!
Answer:
-0.2
Step-by-step explanation:
Sine and cosine are co-functions.
That means, cos(90-x)=sin(x) or sin(90-x)=cos(x).
So here since cos(90-x)=-0.2, then sin(x)=-0.2.
A = pi*r^2
(16/25)*pi = pi*r^2
16/25 = r^2
rt(16/25) = r
r = 4/5
C = 2pi*r
C = 2pi*(4/5)
C = (8/5) pi cm
You get an answer of an even number
Hope this helped:)
