Answer:
The 2 numbers are 37 and 39
Step-by-step explanation:
Let the first number be x
The next number that is odd is 2 away from it ( 1 is odd, 3 is the next number that is odd )
x, x+2 are the two numbers
Add them together to get 76
x + x+2 = 76
Combine like terms
2x+2 = 76
Subtract 2 from each side
2x+2-2 = 76-2
2x = 74
Divide by 2
2x/2 = 74/2
x= 37
x+2 = 39
Answer:
So, solution of the differential equation is

Step-by-step explanation:
We have the given differential equation: y′′+4y=5xcos(2x)
We use the Method of Undetermined Coefficients.
We first solve the homogeneous differential equation y′′+4y=0.

It is a homogeneous solution:

Now, we finding a particular solution.

we get

So, solution of the differential equation is

Answer:
x = 80000/L f
Step-by-step explanation:
When using only three sides for fencing a rectangular area, sides will be
"x " and "y " x = 2*y x is the largest side of the rectangular area
we only fence one y side ( the other side is a river
So the perimeter is L = x + 2*y or L = 4*y
On the other hand if now the area will be 20000 f²
A = x*y = 20000 ⇒ y = 20000/ x
As the fence material is the same as that of the maximum area
L = 4*y L = 4* 20000 / x
L*x = 80000
Then x = 80000/L
Where L is the quantity of fencing material
