Answer:
D) 1
Step-by-step explanation:
When you start raising i to certain powers, you begin to notice a pattern.

This cycle repeats forever. Since 84 is a multiple of 4, i^84 must be 1. Hope this helps!
By AAS congruency the two triangles are congruent
Speed = slope of the line = 20 / 0.5 = 40 km / hr
Second part will be a line with downward slope from the end of the horizontal line Slop = 20 / 1/3 (=60 km/h) So it will pass through the 65 on horizontal axis.
Answer:
$52.50
Step-by-step explanation:
She makes $7.50 an hour multiple that by 7 hours and you get $52.50
25x^2+10x+1
25x^2+5x+5x+1
5x(5x+1)+1(5x+1)
(5x+1)(5x+1)
(5x+1)^2
