G. 226 mm
Step-by-step explanation:
C=2(3.14)(36)
When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.
9h + 15 > 55
Subtract 15 from each side: 9h > 40
Divide each side by 9 : <em> h > 40/9</em>
Any number greater than (4 and 4/9) satisfies the inequality.
Answer: 2061
Step-by-step explanation:
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.
B because x is the independent variable; you could choose any number for x
