Answer:
Step-by-step explanation:
Ok, so we start by setting the integral up. The integral we need to solve is:
so according to the instructions of the problem, we need to start by using some substitution. The substitution will be done as follows:
U=5+x
du=dx
x=U-5
so when substituting the integral will look like this:
now we can go ahead and integrate by parts, remember the integration by parts formula looks like this:
so we must define p, q, p' and q':
p=ln U
q'=U-5
and now we plug these into the formula:
Which simplifies to:
Which solves to:
so we can substitute U back, so we get:
and now we can simplify:
notice how all the constants were combined into one big constant C.
Answer:
Salinity
Step-by-step explanation:
Strictly, salinity is part of the load being (dissolved in salt).
6x-2(x+1)>0
6x-2x+2>0
4x+2>0
4x+2-2>-2
4x<1/2
B is equal to 1/5. Hope I was able to help
