Answer:
The power developed by the 1st crane is twice the power developed by the 2nd crane.
Step-by-step explanation:
According to the question,
work done by both of the cranes are the same. Let it be W.
Then power developed by the first crane,
= unit -----------------(1)
and, the power developed by the 2nd crane,
= unit ------------------(2)
So, we get that,
So, the power developed by the 1st crane is twice the power developed by the 2nd crane.
Answer:
Step-by-step explanation:
We can see that this graph looks something like the graph of:
f(x) = 1/x^2
But the asymptotes of 1/x^2 are at x = 0, and in this case we can see that the asymptotes are near x = -3.
This may mean that the graph has been horizontally shifted 3 units to the left.
A general way to write an horizontal shift of N units is:
g(x) = f(x + N)
if N is positive, then the shift is to the left, if N is negative, then the shift is to the right.
In this case, we will have;
g(x) = f(x + 3)
And f(x) = 1/x^2
then:
g(x) = 1/(x + 3)^2
Graphing that, we get the graph shown below, that is almost the same as the graph in the image.
