a.
To identify: The type of observational study.
This observational study is prospective.
Given information:
An observational study is retrospective if it considers only existing data.
It is prospective if the study design calls for data to be collected as time goes on.
Explanation:
Naturalists will collect data in the coming a ten-year period.
Thus, this observational study is prospective.
b.
To identify: The type of observational study.
This observational study is retrospective.
Given information:
An observational study is retrospective if it considers only existing data.
It is prospective if the study design calls for data to be collected as time goes on.
Explanation:
Researcher is studying a recorded data.
Thus, this observational study is retrospective.

d.
To identify: The type of observational study.
This observational study is prospective.
Given information:
An observational study is retrospective if it considers only existing data.
It is prospective if the study design calls for data to be collected as time goes on.
Explanation:
Here, the study calls for data to be collected after the soldiers return from active duty.
Thus, this observational study is prospective.

- Let the region R be the area enclosed by the function f(x)= = 3x² and g(x) = 4x. If the region R is the base of a solid such that each cross section perpendicular to the x-axis is an isosceles right triangle with a leg in the region R, find the volume of the solid. You may use a calculator and round to the nearest thousandth. y 11 10 9 00 8 7 9 5 4 3 2 1 -1 -1 x 1 2arrow_forwardLet the region R be the area enclosed by the function f(x) = ex — 1, the horizontal line y = -4 and the vertical lines x = 0 and x = 3.
