Answer:
i Choice A
Step-by-step explanation:
i ^ 41
we use the rule of 4 for powers of i
if you get remainder of 0 = 1
if you get remainder of 1 = i
if you get remainder of 2= -1
if you get remainder of 1 = -i
41/4 = 10 remainder 1
so i^41 = i
We are given with 90<x<180 degrees and asks for the value of sin(x/2), cos(x/2) and tan(x/2). We just substitute the maximum and minimum angle to the equations. sin (180/2) is equal to 1 and sin (90/2) is equal to

to 1. cos (x/2) is equal to 0≤y≤<span>

. tan (x/2) is equal to 1 to infinity. </span>
Answer:
why dont you use photo math
Step-by-step explanation:
Answer:
y=-3
Step-by-step explanation:
If the line is parallel to the x-axis then it is a horizontal line with slope 0. These lines have form y=b where b is the y-intercept or y value of all points. y=-3 is the line since (2,-3) is on the line.
-2/5n=-30n
multiply both sides by -1 sinc I don' like negatives
2/5n=30n
multipl yboth sides by 5/2
1n=150/2n
n=75n
this is obviously false, the only number that would work is 0 since 0 =0 times 75
n=0
