Answer:
4√37 units
Step-by-step explanation:
Side AB has a length given by the distance formula:
d = √((x2-x1)² +(y2-y1)²)
d = √((2-3)² +(-2-4)) = √(1+36) = √37
The perimeter of the square is the sum of the lengths of four sides that are this length, so is ...
P = 4d = 4√37 . . . units
Answer:
It is false that, if the national economy shrank at an annual rate of 9% per year for three consecutive years then the economy shrank by 27% over the 3-year period, because this percentage does not follow a linear path, but on the contrary, it is calculated exponentially: 9% of each year is calculated on the rest that remained after discounting 9% the previous year.
Thus, if the national economy has a value of 100, after three years it will not have a value of 79, but a value of 75.35, as it arises from the following calculation:
100 x 0.91 ^ 3 = X
100 x 0.753571 = X
75.35 = X
