Express the complex number in trigonometric form. 2i

Another way to word the answer up top for those of you looking for the degree:

z=2i=2(cos(90)+i sin(90))

Same thing from up top, just converted the pi/2 to 90

pi/2*180/pi=180/2=90

$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)

is only a line? i think so
