Answer:
19 ft by 38 feets
Step-by-step explanation:
Given that :
Available fencing = 76 feets
Rectangular fencing with 3 sides
Let the 3 sides be :
x, x, y
x + x + y = 2x + y = 76
y = 76 - 2x
Area = x * y = xy
Area = (76 - 2x) * x
Area = 76x - 2x²
Take derivative of Area with respect to x ; dA
dA /dx = 76 - 4x = 0
76 - 4x = 0
-4x = - 76
x = 76 / 4
x = 19
2x + y = 76
2(19) + y = 76
38 + y = 76
y = 76 - 38
y = 38
Hence, dimension : 19feet by 38 feets
Answer:
C.
Step-by-step explanation:
Adding to the x value makes a point go appear more right. Subtracting some from the y value makes a point go appear down.
15% in decimal form would be 0.15. 1/2 would be 0.50. So following that, if we were to place these in greatest to least form, then it would be: 0.50, 0.15, 0.09, 0.2. I hope I've ordered these correctly and that I've helped. Have a nice day.
