Answer:
20 mph and 4 mph
Step-by-step explanation:
GIVEN: A boat travels upstream for 
miles in 
hours and returns in 
hours traveling downstream in a river.
TO FIND: What is the rate of the boat in still water and the rate of the current.
SOLUTION:
Let the speed of boat in still water be 
and speed of current be 
.
speed of water in upstream 
speed of water in downstream 
As 
Solving both we get
Hence speed of boat in still water and rate of current is 20mph and 4mph respectively.

I’m asking the same question please help us!!! Thank you
Y=cos(2x+pi) - 2
y= - cos(2x) - 2
{ Since cos(x+pi) =-cos(x)}
(10x)^ (-3)
= 1/ [(10x)^3]
= 1/ [10^3* x^3]
= 1/ (1000x^3)
The final answer is 1/ (1000x^3), and I don't think there is a correct option to choose from. ( option c would be correct if it were written with round brackets)
Hope this helps~
