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:
11.235955
Step-by-step explanation:
7÷0.623
11.235955
You have to multiply each side by 2.5 then multiply the two new sides to get the answer. So 8 1/2, which is 8.5 is going to become 21.25 and 11*2.5 is going to become 27.50. So the new dimensions are 21.25 and 27.50, you multiply both of them which would give you an area of 584.375. YOU'RE WELCOME :)
