If something happens to alter the quantity demanded at any given price, then a. the demand curve becomes steeper. b. the demand curve becomes flatter. c. the demand curve shifts. d. we move along the demand curve.

C. the demand curve shifts.

Step-by-step explanation:

If quantity demanded changes at any given price, there is a shift (right or left) from any given price. Graphically, this is a shift in the demand curve itself.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
