Answer:
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
Permutations of four letters from a set of 12 letters. So
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Answer:
1)
2)
Step-by-step explanation:
Assuming that our function is for the first case and for the second case.
Part 1
We can rewrite the expression like this:
And we can reorder the terms like this:
Now if we apply integral in both sides we got:
And after do the integrals we got:
Now we can use the initial condition
And the final solution would be:
Part 2
We can rewrite the expression like this:
And we can reorder the terms like this:
Now if we apply integral in both sides we got:
And after do the integrals we got:
Now we can use the initial condition
And the final solution would be:
first off let's take a peek at what the slanted side of the base is hmmm
Check the picture below, the lateral surface, namely just the sides, excluding top and bottom, is really just 3 rectangles, so let's get their area and sum them up.
