Complex numbers multiplication is commutative.
so
given
= (2+i)(1+2i) * (3-i)(3+i) * (1-i)
|(2+i)(1+2i)| has 5 as its absolute value and geometrically thinking its argument is pi/2. so
(2+i)(i+2i) = 5i
and obviously
(3+i)(3-i) = 10
so the answer is
50i * (1-i) = 50 + 50i
maybe, I think...
Answer C explanation: Alternate interior angles are always congruent
What are you solving for? For y: y=x or for x: x=y
Answer:
( x+ 2.4) ^2 + ( y+4.8) ^2 = 45
Step-by-step explanation:
The equation of a circle can be written as
( x-h) ^2 + ( y-k) ^2 = r^2
Where ( h,k) is the center and r is the radius
( x-- 2.4) ^2 + ( y--4.8) ^2 = (sqrt45)^2
( x+ 2.4) ^2 + ( y+4.8) ^2 = 45
