The answer is 6.524. Hope this helps! :D
Write i in trigonometric form. Since |i| = 1 and arg(i) = π/2, we have
i = exp(i π/2) = cos(π/2) + i sin(π/2)
By DeMoivre's theorem,
i² = exp(i π/2)² = exp(i π) = cos(π) + i sin(π)
and it follows that i² = -1 since cos(π) = -1 and sin(π) = 0.
Answer:
0.14
Step-by-step explanation:
The way to solve this problem is to add everything together. 20+60 is 80, and there are two 30 gram slices of bread (30 x 2 = 60) so you add the 80 from before to the two slices of bread, which is 80 + 60, and that equals 140 grams total. Since there are 1000 grams in 1 kilogram, you have to divide this by 1000, giving you 0.14 or 14/1000.
