<span>The exact solution of cos (17</span>π<span>/6) is as follows:
First change the angle into degrees.
17(</span>π/6) (180°/π) = 510°
Then we calculate the cosine of the angle above and it as follows:
cos 510° = -(√3)/2
Hope this answers the question. Have a nice day.

Answer:
5.1 cm
Step-by-step explanation:
The equation for the circumference of a circle is 2πr or πd.
So, we can plug in 16 and 3.14 to get 16 = 3.14×diameter.
Divide both sides by 3.14 to get approximately 5.1 cm.
Hope that helps! :)

<em>Correct option: C]</em>
Step-by-step explanation:
<u>Arithmetic Sequences</u>
Each term in an arithmetic sequence is obtained as the previous term plus a constant number called the common difference. The general term is
We are given this information
Replacing those values in the formula
Solving for r
The general term is, then
Or equivalently
