Answer:
(a) 
Multiplicative inverse of w will be 
(B) As w is same as the product of 
So there multiplicative inverse will also be same
Step-by-step explanation:
We have given two complex numbers
and 
(a) First we have to find 
So 
As we know that 
So 
Multiplicative inverse :
It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1
So multiplicative inverse of w will be 
Because when we multiply
with
it gives result as 1
(b) As w is same as the product of 
So there multiplicative inverse will also be same
The equation youre using is y=mx+b
b is the y int which 3 and the slope between the points is 5/2 so your equation is y=5/2x+3
The simple interest rate was: 1.25%
Step-by-step explanation:
Simple interest is given by:

Given
Principal amount =$3000
Time = t = 2 years
Interest amount = A = $75
putting the values in the formula

Dividing both sides by 6000

So,
The rate is:
0.0125 * 100 = 1.25%
Hence,
the simple interest rate was: 1.25%

Answer:
All of the planets in our solar system revolve around one star-our sun.
The sun's gravity holds the planets in place.
Astronomers long ago and today use star charts to map star locations.

We call a full circle or a full rotation 360 degrees. There's nothing magic
or mathematical about that number. It was invented by people. It could
have been any number they wanted.
But it was a great choice because it has a lot of factors. With 360 degrees
in a full rotation, you can split up a full rotation into 2, 3, 4, 5, 6, 8, 9, 10, 12,
15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, or 180 equal pieces, without
ever slicing up a degree !
