URGENT Find all seventh roots of unity and sketch them on the axes below.

The 7th roots are :

Step-by-step explanation:

The roots of unity are evenly spread around the unit circle.      

The roots of unity can be find by using the relation

Now z be a polynomial.

therefore, cos 0 = 1.

Now, for k=0, z = 1

Then the 7th roots are :

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
