Answer:
where is the question?
Step-by-step explanation:
6(4j - 6)
Distributing,
6(4j) - 6(6)
24j - 36
which is not equivalent to 24 - 36j
Vector QP= (-5+6, 11-4) = (1, 7)
its magnitude is QP= sqrt( 1 + 49)= sqrt (50)=5sqrt2
-1(y-1)
-y+1 would be the simplified version so yes, it can be distributed
I hope this helps

Let the time to hike up the hill = t
As given that the total time time up and down is 3 hrs, therefore
The time down the hill = 3-t
The distance up and down is the same.
Distance = speed * time



t=1.8
Hence, time taken to uphill = 1.8 hours
Time taken to down hill = 3-18 = 1.2 hours
