Answer:
308[cos(45) + isin(45)]
Step-by-step explanation:
z1×z2:
Modulus: r1 × r2
= 7×44 = 308
Argument: theta1 + theta2
= -70 + 115 = 45
z1z2 = 308[cos(45) + isin(45)]
Or
z1z2 = 154sqrt(2) + (i)154sqrt(2)
sqrt: square root
Answer:
Yeah
Step-by-step explanation:
lol
Answer:
I = p× r× t
300×8×4
pinicipal × rate × time
That is the formula
the answer is 300×8×4= 9600
