The tape diagram should have one box for $5, 121 as the total. And some more boxes where the value is 14.50. Hope this helps!
Answer:
The most straightforward way to obtain the expression for cos(2x) is by using the "cosine of the sum" formula: cos(x + y) = cosx*cosy - sinx*siny. cos(2x) = cos² (x) - (1 - cos²(x)) = 2cos²(x) - 1. = 2cos²(x) - 1.
Step-by-step explanation:
16= 32 =48. 72- 48 = 24. The third side of the triangle is 24! Hope this helps, have a great day! :)
