Answer: 6720
Step-by-step explanation:
The number of permutations of n things taken r at a time is given by the following formula:
Similarly, for n=8 and r=5, the number of permutations of 8 things taken 5 at a time will be:
Hence,
The permutation is solved and the expression is ⁸P₅ = 6,720
Given data ,
The notation "8P5" represents the permutation of 8 objects taken 5 at a time.
The formula for permutation is given by: P(n, r) = n! / (n - r)!
Using this formula, we can calculate ⁸P₅ as follows:
permutation ⁸P₅ = 8! / (8 - 5)!
⁸P₅ = 8! / 3!
⁸P₅ = (8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1)
⁸P₅ = 8 * 7 * 6 * 5 * 4
permutation ⁸P₅ = 6,720
Therefore, the expression ⁸P₅ is equal to 6,720
Hence , the permutation is solved

There are so many parts to this question that I would normally skip it ...
I mean, even though there are only 4 letters, it needs 7 answers.
But I was so overcome with shock and awe at the sight of the bountiful
5 points at the end of the rainbow that I just couldn't pass it by.
Tim can paint a house in 6 days.
Tara can paint a house in 3 days.
a). Tim paints 1/6 of a house in one day.
Tara paints 1/3 of a house in one day.
b). In 'd' days, Time can paint d/6 of a house.
In 'd' days, Tara can paint d/3 of a house.
c). In one day, Tim and Tara together can paint (1/6 + 1/3) = 1/2 of a house.
In 'd' days, Tim and Tara together can paint (d/6 + d/3) = d/2 of a house.
d). The number of days it will take Tim and Tara together to paint
a whole house is
N = 1 / (1/6 + 1/3)
N = 1 / (1/2)
N = 2 .

Just use the area formula: 3.14 *r^2 to find the total area of 339.62 and then divide this by 3 to get 113.21. Then to subtract the triangle..find the area of the traingle which is 1/2 (10.4)^2 = 54.08. 113.21 - 54.08 = 59.13 which should be your answer
