Hum, this problem was difficult. You use the next expression to solve this problem. \[\cos (A - B) = \cos A \cos B + \sin A \sin B \] \[\cos (A + B) = \cos A \cos B - \sin A \sin B\] \[\cos (A - B ) - \cos (A +B ) =2 \sin A \sin B\] So \[\sin A \sin B = 0.5 \left( \cos(A - B) - \cos(A + B) \right)\] A = 1.8 x, B = 0.5 x \[\sin (1.8x) \sin (0.5x) = 0.5\left( \cos(1.8-0.5)x - \cos(1.8+0.5)x \right)\]\[= 0.5 \left( \cos(1.3x) - \cos (2.3x) \right)\] It's finish !!
You’ll need to combine like terms to solve. All terms are x here, so we simply add all coefficients. 2 + 1 + 2 + 1 = 6, so the sum will be 6x.
(Not my own work.)
8 = 2 x 2 x 2
<span>30 = ...........2 x 3 x 5 </span>
<span>75 = ................3 x 5 x 5 </span>
<span>-------------------------------------- </span>
<span>....= 2 x 2 x 2 x 3 x 5 x 5 </span>
<span>....= 600</span>
Hello,
How are you doing? I believe you are asking for something like 162 water bottles in 9 cases? So in this case, you need to do the math like the following!
162/9 = 18 water bottles per case or
18:1
Thank you,
Darian D.
