devlian [24]

Answer:

13y= x + 59

Step-by-step explanation:

gradient= y² - y¹ / x²- x¹

=5 - 4 / 6- -7

= 1/ 13

<h3>equation of line: y=mx+c</h3>

x y

5= 1 (6) + c

c = 5 - 6

= 59

y=mx+c

For z = 2cis 60°, find z4 in rectangular form.

a_sh-v [17]

By DeMoivre's theorem,

$z=2\mathrm{cis}60^\circ\implies z^4=2^4\mathrm{cis}(4\times60)^\circ=16\mathrm{cis}\,240^\circ$
$z^4=16(\cos240^\circ+i\sin240^\circ)$
$z^4=16\left(-\dfrac12-i\dfrac{\sqrt3}2\right)$
$z^4=-8-i8\sqrt3$
