Answer:
(-3, 3√3)
Step-by-step explanation:
Evaluate each of the coordinates. Keep or drop the "i" as your convention requires.
6(cos(120°), i·sin(120°)) = (6·cos(120°), i·6·sin(120°)) = (6(-0.5), i·6·√3/2)
= (-3, 3√3 i)
You may want the (x, y) coordinates written as (-3, 3√3).
___
In the complex plane, this is -3+i·3√3.
Since she runs 6
miles each day and there 7 days per week, you will have to multiply 6
times 7.
But since you have to use distributive properties, multiply like this (6
)(7)
6
is equal to 
Now turn 7 into a fraction, so its 
Now multipy (6
)(
)
Multiply the numerators, so its 7 * 13 which gives you 91 and multiply the denominators so its 1 * 2 which gives you 2.
Put that back into a fraction as 
Divde it to change it to a mixed number and the answer is 45
