Rather than carrying out IBP several times, let's establish a more general result. Let

One round of IBP, setting


gives


This is called a power-reduction formula. We could try solving for
explicitly, but no need.
is small enough to just expand
as much as we need to.





Finally,

so we end up with


and the antiderivative is

5. since .6 is greater than 5, we round up.
The product of 14560 and 10 is 145600
It would be 60. He sold his painting for 50 which was 10 less that the original price. So 50+10=60
Answer:
FOr the first one you can do:
y= -x +4
y= -x+2
y = -x
y= -x-2
y = x-4
Step-by-step explanation:
I'll do the second one in a different answer use these for now.
