The answer would be 2160 because v=l*w*h so 10*12*18 would equal 2160
Let's look at the difference in speed between the two: it's 39-15.6=23.4 km/h
(we can just subtract this because they are traveling in the same direction) - this means that it's as if the slower train (the freight) was in place and the passenger train was traveling at 23.4 km/h
No, the freighter left 3.9 hours earlier, during which it traveled
15.6*3.9=60.84 km
So they will meet when the passenger train will catch up on those 60.84 km.
It does it with 23.4 km/h so it will need:
So the freighter will be travellinf for 2.6 more hours than the other train - a total of (2.6+3.9=6.5) 6.5 hours!
The square root of 100 and of 0.25 are both rational as they are finite numbers, the square root of 100 being 10 and the square root of 0.25 being 0.5.
Step-by-step explanation:
x^4+4y=8xy
=>8xy-4y=x^4
=>4y(2x-1)=x^4
=>4y=x^4/(2x-1)
differentiating both side we got
4 dy/dx={4x^3(2x-1)-2x^4}/(2x-1)^2
i.e, dy/dx=(6x^4-4x^3)/4(2x-1)^2
=(6x^4-4x^3)/(16x^2-16x+4)

-5+(-4)
-5-4
-9
Therefore, -9 is the correct answer
