The answer is b, it would root 2x² which would simplify into x root 2
Answer:
Step-by-step explanation:
3 1/7 = 3.142857
3 10/71 = 3.140845
Actual value of pi = 3.14159 to 5 decimal places.
The actual value of pi is larger than 3.140845
The actual value of pi is smaller than 3.142857.
Note the key word is between
3.1408 < pi < 3.142857
When I taught school, I tried to impress upon my students that the counting systems of the ancients was so crude that it was a miracle they could come up with any kind of estimate especially one like 3 and 10/71.
There is mention of pi in the Bible (somewhere in 2nd Kings). It gives a value of 3. You make think that is a pretty poor estimate. but if you knew how the counting system worked, you'd be impressed by how good the answer was. The history of man is one of baby steps until now when we are making giant strides in almost every field that involves numbers. Any mysteries have multiplied by just as much.
Answer:
k pi for k = 0, plus-or-minus 2, plus-or-minus 4, ellipsis
Step-by-step explanation:
The cosine is a maximum when its argument is at multiples of 2π.
k pi for k = 0, plus-or-minus 2, plus-or-minus 4, ellipsis
_____
Both of us could probably read this more easily if you would use appropriate math symbols.
The room is 22.4 feet long
7cm=16ft
9.8cm=?ft
7cm 9.8cm
______=______
16ft x ft
Cross multiply
7x=156.8
divide both sides by 7
x=22.4 ft
