7/2
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
The remainder of n/4 is 2
n/4 represents the exponent
For example if n=6 then when we divide 6/4 the remainder is 2
if n=6 then i^6 = i^4 * i^2 = 1* (-1) = -1
The value of i^2=-1
i^2 = -i
i^4= 1
So if the remainder of n/2 =2 then it means i^2 = -1
the value of i^n =-1
Answer:
7.5 hours
Step-by-step explanation:
<u>1 method:</u>
Amber drove at an average speed of 55 mph.
Austin averaged 75 mph per hour.
The difference in speed is 20 mph, this means that each hour Austin drove 20 miles more.
Amber drove 110 miles in 2 hours, then Austin needs 110:2=5.5 hours to catch Amber, so in total after 5.5+2=7.5 hours Austin will catch up Amber.
<u>2 method:</u>
Let t hours be the time Amber was driving, then t-2 hours ia Austin's time.
Amber distance = 55t miles
Austin's distance = 75(t-2) miles
When Austin caught up with Amber, their distances are the same:
