<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.

To get the total cost, add the tax rate to 1, then multiply that by the price of the cartridge:
Total: 17.50 x 1.0925 = $19.12
25% off translates into 0.25($30) = $7.50 off.
A faster way to determine the sales price is to subtract 0.25 from 1.00 and then mult. the regular price by the result: sales price = 0.75($30) = $22.50 (answer)
3/2/3 - 1/1/4
= 3/8/12 - 1/3/12
= 2/5/12
