Answer:
Fran's upstream speed (against the current):
2.9 km/hr - 0.1 km/hr = 2.8 km/hr
Fran's downstream speed (with the current):
2.9 km/hr + 0.1 km/hr = 3.0 km/hr
Using the distance formula for calculating time:
rate x time = distance
time = distance / rate
Fran's upstream time = 9 / 2.8 = 3.21 hrs
Fran's downstream time = 9 / 3.0 = 3.0 hrs
Answer:Thus, (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm
So for (-3)-4 , n= -3 and -m= -4 (or m= 4).
Thus, (-3)-4 = 1/(-3)4.
