Answer:
It would be <u>97.50</u> square deckles.
Step-by-step explanation:
Given:
On the distant plant, Mathology, a sports area covers 7400 yodels².
1 deckle = 75.9 yodels.
Now, to get the square deckles.
As given, 1 deckle = 75.9 yodels.
So, to get the square deckles by using conversion factor:
<em>75.9 yodels = 1 deckle.</em>
7400 yodels² =
=
Therefore, it would be 97.50 square deckles.
Answer: see proof below
<u>Step-by-step explanation:</u>
Use the following Half-Angle Identities:
sin² A = (1 - cos 2A)/2
cos² A = (1 + cos 2A)/2
<u>Proof LHS → RHS:</u>
LHS: sin⁴ A
Expand: sin² A · sin² A
LHS = RHS
The distance they can see: d = √ ( 3 h / 2 )
d ( Addison ) = √ ( 3 · 256/3 / 2 ) = √ 124 = √ 64 · 2 = 8 √ 2d ( Kaylib ) = √ ( 3 · 48 / 2 ) = √ 72 = √ 36 · 2 = 6 √ 2d ( Addison ) - d ( Kaylib ) = 8 √ 2 - 6 √ 2 = 2 √ 2Answer: b. 2 √ 2 mi.
