Answer:
23,600.
Step-by-step explanation:
23|6
Let x = length and y = width
You would have 2 lengths, so 2x and 3 widths, so 3y
Those need to equal total length of fence:
2x + 3y = 1200
The 3 widths would equal total fence minus the 2 lengths:
3Y = 1200-2x
Solve for y: y = 400 -2/3x
Area = length x width = xy. Replace y :
Area = x(400-2/3x) = 400x-2/3x^2
Differentiate:
400-4x/3 =0
4x/3 = 400
4x = 1200
X = 300
Y = 400-2/3(300) = 200
The dimension would be 300 ft x 200 ft
Answer:
Step-by-step explanation:
The answer (y intercept) occurs when x = 0
The answer is -2
-5y = 10
y = 10/-5
y = - 2
9514 1404 393
Explanation:
Your different answers came about as a result of an error you made in the Pythagorean theorem calculation.
√(100 +100) = √200 = 14.142 . . . . same as vector calculation
We have
so this is indeed a difference of squares. Factorizing would give
making the answer D.
We can further factor the first term here and write
but that's clearly out of the scope of this question.
