The amount of candy left in a halloween bucket is given by the function a(t) = 50(0.8)t where t stands for the number of minutes the candy is available and a(t) stands for the amount of candy left at any given time. how much candy is there after five minutes?
as we can see it's a geometric progression.
q = a2/a1
q = 1/3
an = a1 . q^(n - 1)
an = 3 . (1/3)^(n - 1)
the one which matches is f(n) = 3 . (1/3)^(n - 1)
the area of a right triangle is 1/2 the area of a rectangle with the same dimensions
the triangle has a base of 12 and a height of 5
a rectangle of length 12 and a height 5 will be twice the area
