Assume that two int constants, FIRST_YEAR and LAST_YEAR have already been declared and initialized with year values (like 2009, 2014), along with a double variable oil that has been initialized with the number of barrels of oil consumed in Canada in the year given by FIRST_YEAR.

#include <iostream>

using namespace std;

int main()

{

int count;

double oil=10.88;

int FIRST_YEAR=2009,LAST_YEAR=2014;

count = FIRST_YEAR;

do

{

cout << count << ": " << oil << endl;

oil *= 1.20;

count++;

} while ( count <= LAST_YEAR );

return 0;

}

Explanation:

Declare the required variables.Use a do-while loop that runs from first year to last year .Display count of oil .Increment oil by 20%  and count by 1.

Hypothesis: volumes of both figures are equal.the volume of  figure 1 is: .the volume of figure 2 is: .since , you can conclude that and . so, .volumes of figures are equal only when an angle in the basis is right (then figures will be the same), in another cases volume of figure 1 is less than volume of figure 2.the hypothesis was not correct in all cases.

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !
