Statement 1: 2AB = AC
Reason 1: Given
--------------------------------------------
Statement 2: AC = AB+BC
Reason 2: Segment addition postulate (which your teacher abbreviated to "Seg + Post")
--------------------------------------------
Statement 3: 2AB = AB+BC
Reason 3: Substitution
--------------------------------------------
Statement 4: 2AB-AB = AB+BC-AB
Reason 4: Subtraction Property of Equality
---------------------------------------------
Statement 5: AB = BC
Reason 5: Combine like terms
----------------------------------------------
Notes:
- The first reason is "given" since we just simply restate what the instructions provide. If you are given multiple items, you list each one at a time.
- The segment addition postulate is where we break a line into smaller parts and then build it back together.
- Substitution is simply replacement. We've replaced AC with 2AB.
- The subtraction property of equality is the idea where we subtract the same thing from both sides. In statement 4, we're subtracting AB from both sides.
- The last statement of any proof is always the thing we're trying to prove. Once we reach such a statement, there's no need to go any further since the proof has concluded.
Let the lenght perpendicular to street = x
Means lenght two sides will be x and x
Another side of retangle will be = 256 - 2x
Area of rectangle will be= A = x * (256-2x) = 256 x - 2 x^2
For maximum area, dA/dx = 0
d/dx (256 x - 2 x^2) = 0
256 - 4 x = 0
4 x = 256
x = 64 feet
Means one side is 64 feet
Another side will be = 256 - 2 * 64 = 128
Now we have two sides of rectangle 64 and 128
Area = 128 * 64 = 8192 square feet : Answer
Hope it will help :)
Answer:
The answer is False
Step-by-step explanation:
C = pi * d
Plug in what we know:
C = 3.14 * 26
Multiply:
C = 81.64
