Hello,
aPb=b*(b-1)*(b-2)*....*(b-a+1) / a!
3P5=5*4*3/(3*2*1)=10
If we name the number of the employers 1,2,3,4,5
Here are the choices:
123,124,125,134,135,145,234,235,245,345 (total 10 choices)
Sin x = square root (2) / 2
In order for us to get for cos x and tan x, first we need to know what
Hypotenuse, Adjacent, and Opposite sides.
sin x = opposite / hypotenuse.
adjacent = square root (hypotenuse^2 - opposite^2)
adjacent = square root (2^2 - square root(2)^2)
adjacent = square root (4 - 2)
adjacent = square root (2)
cos x = adjacent / hypotenuse
tan x = opposite / adjacent..
cos x = square root (2) / 2
tan x = square root (2) / <span>square root (2) = 1
So, </span>cos x = square root (2) / 2 and tan x<span> = 1</span>
Check the forward differences of the sequence.
If , then let be the sequence of first-order differences of . That is, for n ≥ 1,
so that .
Let be the sequence of differences of ,
and we see that this is a constant sequence, . In other words, is an arithmetic sequence with common difference between terms of 2. That is,
and we can solve for in terms of :
and so on down to
We solve for in the same way.
Then
and so on down to
Answer: The three different equations will be
Step-by-step explanation:
We have to write three equation that have x = 5 as a solution:
1) First equation will be
2) Second equation will be
3) Third equation will be
Hence, the three different equations will be
