Perimeter = 2(Length) + 2(Width)
300 = 2L + 2W → 150 = L + W → 150 - L = W
Area = Length · Width
= L(150 - L) →
= 150L - L²
There are 2 different methods for solving (depending on which math course you are taking).
<u>Calculus</u>: find the derivative, set it equal to zero, and solve for L.
= 150L - L² → 0 = 150 - 2L → 2L = 150 → L = 75
<u>Algebra</u>: find the vertex.
= - L² + 150L → L = -b/2a → L = -150/2(-1) → L = 75
Once you solve for L, plug it into the Perimeter equation to solve for W:
150 - L = W → 150 - 75 = W → W = 75
Answer: 75ft x 75ft
Answer:
it is 36 inches
Step-by-step explanation:
Answer:
- <u><em> 3 + 6 = 9</em></u>
- <u><em>2 + 1 + 4 + 2 = 9</em></u>
- <u><em>18 : 2 = 9</em></u>
- <u><em>3 + 3 + 3 = 9</em></u>
Step-by-step explanation:
Which expression is equivalent to
(3²)
3² = 9
- 2 + 1 + 4 + 2 = 9
- 18 : 2 = 9
- 3 + 3 + 3 = 9
Answer:
X =3.410
Step-by-step explanation:
Sin(angle) = opposite/hypotenuse
Sin(43) =x/5
0.6819 = x/5
X = 3.41
