Answer:
5/2, 2.6, 1 + sqrt(3), sqrt(8)
Step-by-step explanation:
Use a calculator:
sqrt(8) = 2.83
5/2 = 2.5
2.6 = 2.6
1 + sqrt(3) = 2.73
Answer:
5/2, 2.6, 1 + sqrt(3), sqrt(8)
Answer:
Step-by-step explanation:
Volume = 198 ft
length * width * height = 198
(x - 1) * (x + 4) * 3 = 198
(x - 1) * (x + 4) = 198/3
(x - 1) * (x + 4) = 66
x*x + x*4 -1*x - 1*4 = 66 {Use FOIL method to multiply}
x² + 4x - x - 4 = 66
x² + 3x - 4 =66
x² + 3x - 4 - 66 = 0
x² + 3x - 70 = 0
Now factorize.
x² + 10x - 7x - 7*10 = 0
x(x +10) - 7(x + 10 ) = 0
(x + 10)(x - 7) = 0
x - 7 = 0 {x + 10 is ignored because measurement cannot be in negative}
x = 7
length = x - 1 = 7 - 1 = 6ft
Width = x + 4 = 7 + 4 = 11 ft
Answer:
9/16
Step-by-step explanation:
Derivative rule:
Here, n=-1, so
Evaluating this at x=-4 gives 9/16
Across the large angle is going to be large side, then AB is going to be larger than DF.
