Answer:
3360
Step-by-step explanation:
simple interest=principle*rate*time/100
simple interest=20000*5.6*3/100
simple interest= 200*5.6*3
simple interest = 3360
For the answer to the question above asking <span>how many years was his money invested? The for the answer above is simple, it is I = Prt
</span>1200 = 1000 * 0.08 * t
<span>1200 = 80t
the answer is 15 years.
I hope my answer helped you. Have a nice day!

Answer:
See explanations below
Step-by-step explanation:
Given the following complex numbers in polar form:
w = 2(cos(90°) + i sin (90°))
sin 90 = 1
cos 90 = 0
Substitute into the formula:
w = 2(0+i(1))
w = 2(0)+2i
w = 0+2i
Hence the value of w in rectangular form is 0+2i
For z:
z =√2(cos(225°) + i sin(225°))
z = √2(-1/√2+ i (-1/√2))
z = -√2/√2 - √2(-1/√2)i
z = -1+ 1i
Hence the value of z in rectangular coordinate is -1+ 1i
For w + z:
w + z = 0+2i + (-1+1i)
w+z = 0+2i-1+i
w+z = -1+3i
Write w+z in polar form
Get the modulus
|w+z| = √(-1)²+3²
|w+z| = √1+9
|w+z| = √10
Get the modulus
theta = tan^-1(-3)
theta = -71.56
theta = 180 - 71.56
theta = 108.43
The expression in polar form is z = √10(cos108.43+isin108.43)
by dy/dx, we'll be assuming that "y" is encapsulating a function, a function in terms of "x".
In expanded form this number would be written as..
4 + 0.9
That's the answer!
Good Luck! :)
