0 or if maybe another 0 for two ZER0s
Answer:
I would say laps per minute
Ans
2:47 mins
Step-by-step explanation:
2 1/6 ÷7/8 = 2 10/21
2 10/12 to decimal 2.47
Answer: You have to find the unit rate so you divide 7.50 by 3 which is 2.50 so for 1 pound it is 2.50, 2 pounds is 5, 3 pounds is 7.50, 4 pounds is 10, and 5 pounds is 12.50
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)
