There are two possible solutions:
1)
When we know that:
when
then:
For
we have:
and:
k = 0
k = 1
k = 2
k = 3
k = 4
k = 5
So the answer is:
2)
We don't know method (1). If so, we could use following identities:
There will be:
Now, we complete the square for:
and for:
When we return to
:
And we have answer:
Step-by-step explanation:
Volume of Cylinder=πr²h
=16084m²
1 whole thing = 6 sixths
3 whole things = 18 sixths
1 third of a whole thing = 2 sixths of it
3 wholes plus 1 third = 18 sixths plus 2 sixths = 20 sixths
Answer: 10 km in one hour
Step-by-step explanation:
If there are nine hours, and we need to find the distance it will cover in one hour, then we need to divide 90 by 9.
90 ÷ 9 = 10
A train covers 10 km in one hour.
Hope this helps!
