i actually can't tell but i think this is right
Answer:
400 m^2.
Step-by-step explanation:
The largest area is obtained where the enclosure is a square.
I think that's the right answer because a square is a special form of a rectangle.
So the square would be 20 * 20 = 400 m^2.
Proof:
Let the sides of the rectangle be x and y m long
The area A = xy.
Also the perimeter 2x + 2y = 80
x + y = 40
y = 40 - x.
So substituting for y in A = xy:-
A = x(40 - x)
A = 40x - x^2
For maximum value of A we find the derivative and equate it to 0:
derivative A' = 40 - 2x = 0
2x = 40
x = 20.
So y = 40 - x
= 40 - 20
=20
x and y are the same value so x = y.
Therefore for maximum area the rectangle is a square.
Answer:
Angle Bisector Theorem
Step-by-step explanation:
Answer:
The transaction will be recorded by the company as :
DR : Non-collectibles $5670
CR : Accounts receivable $5670
Step-by-step explanation:
Amount of money estimated = $5670
The amount which is non-collectible is recorded as a DEBIT transaction by the company because the amount in the non-collectible account can't be received by the company.
But, the amount in the receivables is the amount which is available for receiving and can be received by the company. So, receivable transaction is marked as CREDIT by the company.
Thus, the transaction will be recorded by the company as :
DR : Non-collectibles $5670
CR : Accounts receivable $5670

the triangles are similar, the angles are congruents then
so... just add them up, and divide by 2, or set them as rational
