Answer:
7x = y + 37
Step-by-step explanation:
y = 7x - 9
Differentiating y with respect to x, we have as follows:
dy/dx = m = 7 ( where m is the slope)
Using the formula y - y1 = m(x - x1) to obtain the equation of line passing through point (4.-9)
y + 9 = 7(x - 4)
y + 9 = 7x - 28
∴ 7x = y + 37
First convert the complex number to polar form
|5 - 5sqrt3i| = 25sqrt10
argument = arctan - sqrt3 = -pi/3
so 5 - 5sqrt3i = 25sqrt10(cos(-pi/3) + i sin(-pi/3))
the angle is in the 4th quadrant so we could write it as 2pi-pi/3 = 5p/3
= 25sqrt10(cos 5pi/3 + i sin 5pi/3)
Now if r(cosx + isin x) is a 5th root of 5-5sqrt3i then
r^5(cos x + i sinx)^5 = 25sqrt10(cos 5pi/3 + i sin 5pi/3)
r^5 = 25sqrt10 and cos5x + i sin 5x = cos 5pi/3 + i sin 5pi/3
i have to go urgently so i have to leave it to you to finish this
