Step-by-step explanation:
52/4=13
13*3=39
39+5=44
52-44=8 girls

a. Integrate by parts by taking


Then

We have

and so

or, replacing
,
.
b. From the above recursive relation, we find

Now,

and so we're left with
.
c. Using the previous result, we find
.
d. If the question is asking to find
, then you can just use the same approach as in (c).
But if you're supposed to find
, we have

Substitute

Then

Answer:
0.06
Step-by-step explanation:
-- "Perimeter" means all the way around, all four sides.
-- That's two lengths and two widths.
-- So one length and one width is half of the perimeter.

-- If the width is 5-ft, then the length is (8 - 5) = 3-ft.
