L=w+4 this shows the length is 4 inches longer than width
h=w-2 this shows the height is 2 inches shorter than the width
volume=lwh
so 240=lwh=(w+4)(w)(w-2)
simplify and solve to find the width then you can use that to find the other values as well.
Answer:
The study is an observational study.
Step-by-step explanation:
Observational study: In research methods, the term "observational study" is determined as one of the different studies that are being conducted by the researchers to observe or study the effects of a specific risk factor, treatment, diagnostic test, or some other intervention in the absence of an effort to change which participants are being exposed and which is not being exposed to it.
Types: Cohort study and case-control study.
In the question above, the given statement represents the observational study.

Step-by-step explanation:
a. 0.31
-72\sqrt(5) this is the answer i did all my math and i got this answer
where
.
By continuity of
, you have
As
in the numerator, you approach
; in the denominator, you approach
. So you have an indeterminate form
. Provided the limit indeed exists, L'Hopital's rule can be used.
Now the numerator approaches
, while the denominator approaches
, suggesting the limit above is 2. This means
