Cos 17pi/4 = cos pi/4 because 17pi / 4 = 16pi/4 + pi/40
cos pi/4 = 1 / sqrt2 or 0.7071 to nearest 10,000 th
Answer:
38.485(correct to 5 significant figure)/ 12.25π
Step-by-step explanation:


=38.485(cor. to 5 sig.fig.)/ 12.25π
to find arc length of sector,we need to π(radius²)(sector's degree divided by 360 degree)
Answer:
Step-by-step explanation:
This is an Arithmetic Series with common difference 4 and first term 3
so the nth term an = 3 + (n -1)4
= 4n - 1.
The sum of n terms
= n/2 (a1 + L)
= n/2(3 + 1671)
= 837n.
There are (1671-3) / 4 + 1 = 418 terms in the series,
so the total value of the series is 837*418
= 349,866.

I find that if you transform fractions into decimals, they become marginally easier to work with. Nine over five in decimal form is one point eight. If we divide 1.8 by three (Jean-Claude and his two friends), then we come up with the answer 0.6, which, once turned back into a fraction, would be six over ten, or three over five.
