The product of the complex numbers 65(cos(14°)+ i sin(14°)) and 8(cos(4°)+ i sin(4°)) is 520[cos(18) + isin(18)]
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Complex number is in the form z = a + bi, where a and b are real numbers.
The product of the complex numbers 65(cos(14°)+ i sin(14°)) and 8(cos(4°)+ i sin(4°)) is:
z = 65 * 8 [cos(14 + 4) + isin(14 + 4)] = 520[cos(18) + isin(18)]

He spent 1.25 hours edging.
You can get this by multiplying the total amount of time by the percentage.
.25 * 5 = 1.25
I would decrease 75% for example if you take 2/4 and do the problem above it becomes 1/3 therefore it is 75%
Answer:
It is called the constant ratio.
