Answer:
To solve the above problem we will use the unitary method as follows
As estimated If £ 3 is equivalent to € 4
Then, £ 1 will be equivalent to = € \frac{4}{3}
£ 64.60 will be equivalent to = € \frac{4}{3} \times 64.60 = 1.3333 \times 64.60 = 86.1311
Now you have to round the answer up to 2 decimal points to get the final answer
€ 86.1311 ≈ € 86.13
Thus, £ 64.60 is approximately equal to € 86.13.

Answer:
e^2
Step-by-step explanation:
Let's start from what we know.
Note that:
(sign of last term will be + when n is even and - when n is odd).
Sum is finite so we can split it into two sums, first
with only positive trems (squares of even numbers) and second
with negative (squares of odd numbers). So:
And now the proof.
1) n is even.
In this case, both
and
have
terms. For example if n=8 then:
Generally, there will be:
Now, calculate our sum:
So in this case we prove, that:
2) n is odd.
Here,
has more terms than
. For example if n=7 then:
So there is
terms in
,
terms in
and:
Now, we can calculate our sum:
We consider all possible n so we prove that:
Answer:
4*-2... answer D. is correct :)
Answer:
Step-by-step explanation:
This half life exponential decay equation goes by the formula:
Where
Since half life is given as 22, we plug that into "Half-Life" in the formula for k and then plug in the formula for k into the exponential decay formula:
So,
Now
third choice is correct.
