Answer:
Step-by-step explanation:
Let length be x and breadth be y .
Along the river no fencing is required so total boundary line of the rectangular land = x + y + y = x + 2y
add divider to it so total length
= x + 2y + y = x + 3y
x + 3y = 2400
area A = xy
y ( 2400 - 3y ) = A
2400y - 3y² = A
For maximum area dA / dy = 0
2400 - 6y = 0
y = 400 yards.
x = 1200 yards
largest area = xy
= 48000 sq yards.
Answer:
0
Step-by-step explanation:
If A is an event that will never happen, then P(A)=0
Answer:
Step-by-step explanation:
The first statement, the fourth statement, and the fifth statement are true. The others are not.
In vertex form, looking at the first statement, you can see that the vertex is located at (4, -11), NOT (-8, 5)
The (x - 4)^2 binomial gives you the axis of symmetry, which is x = 4, NOT x = 5.
Answer : 66.6

The volume of the air mattress in liters is 385.43 liters approx.
<h3>What is ideal gas law?</h3>
For an ideal gas(or a gas that behaves sufficiently like an ideal gas), we have the following relation:
where, the symbol denotes:
- P = Pressure of the gas
- V = volume of the gas
- T = temperature of the gas
- n = count of moles of the gas
- R = universal gas constant = 8314.46261815324
For the given case, the gas in the air mattress has following properties:
P = 3.5 kilopascals =3500 pascals
T =295 K
n = 0.55 moles
V = volume of gas in air mattress = volume of mattress (to evaluate).
Thus, using the ideal gas law, we get:
Thus, the volume of the air mattress in liters is 385.43 liters approx.
