Each time the remaining time on the timer halves, the value switches between 0 or 1. For example, when there’s 1 minute left, 1 turns to 0, when there’s 30 secs left, 0 turns to 1, when there’s 15 seconds left, 1 turns to 0 and so on and so on. Because the time can be halved infinitely, will the value be 1 or 0 when the timer reaches two minutes? Please help me out! You'd be of great help. :D

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
