Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
Which question do you need help with?
Answer:
see below
Step-by-step explanation:
f(x)=3log(x−7)+1
There is no y intercept
log (x) does not intercept the y axis. This shifts the function 7 units to the right so the graph will not intercept the y axis
Answer:
angle 2; Angle TSR; Angle RST
Step-by-step explanation:
Make sure S is in the middle of your angle name since that is the vertex of the angle.
