Noah built a fenced dog run that is 8 yards long and 6 yards wide. he placed posts at every corner and every yard along the length and width of the run. how many posts did he use.

24 posts

Step-by-step explanation:

Length = 8 yards

So, No. of parts of 1 yards in 8 yards =

So, One each length there will be 8 posts including 2 corners

So, Total posts on 2 lengths = 8+8=16

Width = 6 yards

So, No. of parts of 1 yards in 6 yards =

Excluding 2 corners, There will be 4 lamps on each width

So, Total posts on both widths excluding corners = 4+4=8

So, Total posts on fence = 16+8 = 24

Hence He used 24 posts .

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

is there a graph
