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?

50 pieces

40 pieces

16 pieces

200 pieces

answer:

step-by-step explanation:

15/60 = 1/4 = 25%

15/3 = 5 = 500%

15/30 = 1/2 = 50%

15/1500 = 1/100 = 1%

answer:

choice b is correct answer.

step-by-step explanation:

we have to find the value of cos∅x where the value of sin∅ is given.

given   that

sin∅ = 1/4

we use   trigonometric identity to solve this question.

trigonometric identity:

sin²∅+cos²∅=1

separating cos²∅

cos²∅= 1-sin²∅

taking square root to above equation

cos∅=√1-sin²∅

cos∅=√1-(sin∅)²

putting the given value of sin∅,we get

cos∅= √1-(1/4)²

cos∅= √1-1/16

cos∅=√16-1/16

cos∅= √15/16

cos∅= (√15)/4

hence, the answer is choice b.

answer:

4/5

step-by-step explanation:

0.8 (to a fraction) 8/10

8/2=4

10/2=5
