Answer:
100/x+6=20/x-6
100x-600=20x+120
80x=720
x=9 miles an hour as the rowing teams' rate in still water
Answer:
t0 = π/4
Step-by-step explanation:
The velocity v(t) = r'(t) = <-2sint,-2cost>
Since <1,-1>⊥v, <1,-1>•v=0. So,
(1)(-2sint) + (-1)(-2cost) = 0
cost - sint = 0
The answer is D, 32pi
The radius is half the diameter, which is 32. The circumference equation is 
or 
So that gives you 32pi
Step-by-step explanation:
i hope it is the right answer
Answer:
8x-24
Step-by-step explanation:
8(x-3)
8 times x= 8x
8 times-3= -24
