Prove:
Using mathemetical induction:
P(n) =
for n=1
P(n) = = 6
It is divisible by 2 and 3
Now, for n=k,
P(k) =
Assuming P(k) is divisible by 2 and 3:
Now, for n=k+1:
P(k+1) =
P(k+1) =
P(k+1) =
Since, we assumed that P(k) is divisible by 2 and 3, therefore, P(k+1) is also
divisible by 2 and 3.
Hence, by mathematical induction, P(n) = is divisible by 2 and 3 for all positive integer n.
There are numerous ways you can do this, but take a look at the attachment to see how I did it. I hope it answers your question! :)
Answer:
Hence r=10.3 cms (rounded to tenth place)
Step-by-step explanation:
In Triangle KLN ,
KN = 5 Cms
LN = ½ of LM
As the Perpendicular dropped from the center to the chord bisects it.
LM = 18 cm
LN = 9 cm
Now we have to find r or KL
We apply Hypotenuse Formula in this
The formula is given as
Where c = r
a=5
b=9
Putting them in the formula
