Answer:
Answer would be 9y+36
Step-by-step explanation:
Because if you distribute the 9 inside the parenthesis, you'd get
9*y=9y and 9*4=36
so 9y+36

Answer:
9/2
distribute the value of x,y, and z, on the given questions, and then you do multiplication, next addition, lastly lowest term.
Answer:
the square root of 75 is either 
or 8.66
Step-by-step explanation:
Answer:
Cartesian
z₁= 3 +4*j
z₂= 2 +3*j
Polar
z₁=5 * e^ (0.927*j)
z₁=√13 * e^ (0.982*j)
Step-by-step explanation:
for the complex numbers z the cartesian form of is
z= x + y*j
then
1) z₁= 3 +4*j (cartesian form)
2) z₂= 2 +3*j (cartesian form)
the polar form is
z= r* e^jθ
where
r= √(x²+y²) → r₁ = √(3²+4²) = 5 , r₂ = √(2²+3²) = √13
and
θ = tan⁻¹ (y/x) → θ₁ = tan⁻¹ (4/3)= 0.927 rad , θ₂ = tan⁻¹ (3/2)= 0.982 rad
then
z₁=5 * e^ (0.927*j)
z₁=√13 * e^ (0.982*j)
