Answer:
Step-by-step explanation:
hmmm
He needs 1080 I believe so 38
because 1042 divided for 45 museums would be 23.15 meaning it wouldn't be the same amount for all
but if they get 38 pictures (1080) and divide it between the 45 museums it would be an even number of 24
so the answer is 38 more pictures
E= 116 joules
That is what I think the answer is
We're given

which immediately tells us that

In other words, swapping the limits of the integral negates its value.
Also,

The integral we want to compute is

which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is
