2Question 1:
Express the given complex number in the form a + ib: (5i)(-3i/5)
Answer:
(5i)(-3i/5) = (-5 * 3/5) * i * i
= -3 * i2
= -3 * (-1) [Since i2 = -1]
= 3When he heard a voice thus calling to him, he was standing at the door of his box, with a flag in his hand, furled round its short pole. One would have thought, considering the nature of the ground, that he could not have doubted from what quarter the voice came; but instead of looking up to where I stood on the top of the steep cutting nearly over his head, he turned himself about, and looked down the Line. There was something remarkable in his manner of doing so, though I could not have said for my life what. But I know it was remarkable enough to attract my notice, even though his figure was foreshortened and shadowed, down in the deep trench, and mine was high above him, so steeped in the glow of an angry sunset, that I had shaded my eyes with my hand before I saw him at all.Arc: Arc is a part of the circumference of a circle. Arc APB is minor arc and arc AQB is major arc.Alex and Sam also build tables.
Together they make 10 tables in 12 days.
Alex working alone can make 10 in 30 days.
How long would it take Sam working alone to make 10 tables?

Letters:
Use a for Alex's work rate
Use s for Sam's work rate
12 days of Alex and Sam is 10 tables -
so: 12a + 12s = 10
30 days of Alex alone is also 10 tables: 30a = 10
We are being asked how long it would take Sam to make 10 tables.
\mathbf\green{To \: slove \: -}Toslove−
30a = 10, so Alex's rate (tables per day) is -
a = 10/30 = 1/3
Start with: 12a + 12s = 10
Put "1/3" for a: 12(1/3) + 12s = 10
Simplify: 4 + 12s = 10
Subtract 4 from both sides: 12s = 6
Divide both sides by 12: s = 6/12
Simplify: s = 1/2
Which means that Sam's rate is half a table a day (faster than Alex!)
So 10 tables would take Sam just 20 days.
