200000J/200KJ
Step-by-step explanation:
using k.e=1/2(mv2)
k.e=1×1000×20²/2
k.e=400000/2
k.e=200000J/200KJ
Answer:
132 inches
Step-by-step explanation:
Each yard is 3 feet, so you have a total of 11 feet. A foot is 12 inches, so just multiply 11 by 12, and you will have 132 inches.
Step-by-step explanation:
Letting the variable x approach 1 will give us , an indeterminate result. In such a case, we can use L'Hopital's rule where
Let and
We can see that
and
Applying L'Hopital's rule, we get
Therefore, as the given expression approaches .
So the ratio of boys to girls is 12:24.. now, is that an equivalent ratio as 2 boys for 4 girls? or 2:4? let's see.
you could start simplifying the 12/24 fraction by dividing by some common multiple, say 2, and get 6/12, then divide by 3 and get 2/4 and stop there.
then you'll notice that 12/24 is really 2/4 in disguise.
