Answer: The number is 1.
Step-by-step explanation:
Here is the equation:
2(1/N) + 3N = 5.
Substitute 1 into the equation.
2(1/1) + 3 * 1 = 5.
2(1) + 3 * 1 = 5.
2 + 3 * 1 = 5.
2 + 3 = 5.
5 = 5.
1 is a solution.
I also found out that any number greater than 1 makes the equation unbalanced, where the left side becomes greater than the right.
And as for negative numbers, they make the left side smaller than the right.
So the only solution is the integer 1.
The ratio of men to women in a certain factory = 3:4
The total number of men in the factory = 222
Let us assume the common ratio to be = x
Then
3x = 222
x = 222/3
= 74
Then
The total number of women workers in the factory = 4 * 74
= 296
So
The total number of workers in the factory = 296 + 222
= 518
From the above deduction we can easily conclude that there are a total of 518 workers in the factory.
Answer:
the answer to that equation would be 27.50
Answer:
Critical points are 1 and -1
Maximum at x=1
Minimum at x=-1
Step-by-step explanation:
We are given that a function
on (
)
We have to find the critical points of the function.
To find the critical point we will differentiate function w.r.t x and then substitute f'(x)=0








Therefore, the critical points of the given function are 1 and -1.



When we goes from 0 to 2 then the sign of derivative change from positive to negative .Therefore, function has local maximum at x=1.



When we goes form -2 to 0 then the sign of derivative change from negative to positive .Hence , function has local minimum at x=-1
Hence, critical points are local maximum and local minimum .
