Answer:
we need to prove : for every integer n>1, the number
is a multiple of 5.
1) check divisibility for n=1,
(divisible)
2) Assume that
is divisible by 5, 
3) Induction,



Now, 



Take out the common factor,
(divisible by 5)
add both the sides by f(k)

We have proved that difference between
and
is divisible by 5.
so, our assumption in step 2 is correct.
Since
is divisible by 5, then
must be divisible by 5 since we are taking the sum of 2 terms that are divisible by 5.
Therefore, for every integer n>1, the number
is a multiple of 5.
Answer:
zero (0)
Step-by-step explanation:

Answer:
Change in productivity will be 50%
So option (b) will be correct option
Step-by-step explanation:
It is given that it takes 8 hour to bake 800 pretzels
And there is a shift of 8 hours
So hourly production = 
Now the production is increases to 1200
Now hourly production = 
So change in productivity =
%
So option (b) will be correct answer
Answer:
<h3>2</h3>
Step-by-step explanation:
The value of pi is 22/7
Expressing as a decimal, the first ten digits of pi is 3.1415926535
The value in the tenth digit of the pi is 5 (tenth value after the decimal point)
The value of the ones is 3(The value before the decimal point)
The difference between both values = 5 - 3
The difference between both values = 2
Hence the difference of the ones and the tenth digit of the pi is 2
