Simplify (10-10i)/(-5i)

Phoenix [80]

Answer:

Step-by-step explanation:

$i-\text{imaginary\ unit}\\\\i=\sqrt{-1}\to i^2=-1\\\\=====================$

$\dfrac{10-10i}{-5i}=\dfrac{10}{-5i}+\dfrac{-10i}{-5i}=\dfrac{(10)(i)}{(-5i)(i)}+2=\dfrac{10i}{(-5)(i^2)}+2\\\\=\dfrac{10i}{(-5)(-1)}+2=\dfrac{10i}{5}+1=2i+2=2+2i$

What is the length of PQ¯¯¯¯¯?

timofeeve [1]

Since you don't have any angle and its opposite side, you cannot establish the ratio for the law of sines, so you must use the law of cosines.

$c^2 = a^2 + b^2 - 2ac \cos C$

Let's change it for this problem.

$r^2 = p^2 + q^2 - 2pq \cos R$

$r^2 = 9^2 + 6^2 - 2(9)(6) \cos 34^\circ$

$r^2 = 9^2 + 6^2 - 2(9)(6) \cos 34^\circ$

$r^2 = 27.46$

$r = 5.24$

$PQ = 5.2~km$
