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?
15/60 = 1/4 = 25%
15/3 = 5 = 500%
15/30 = 1/2 = 50%
15/1500 = 1/100 = 1%
choice b is correct answer.
we have to find the value of cos∅x where the value of sin∅ is given.
sin∅ = 1/4
we use trigonometric identity to solve this question.
taking square root to above equation
putting the given value of sin∅,we get
hence, the answer is choice b.
0.8 (to a fraction) 8/10
