Answer:
Exact form: 9/10 , Decimal form: 0.9
f(t) = 2(0.4)^t
F(-2) means to replace t with -2:
f(-2) = 2(0.4)^-2
f(-2) = 12.5
The value of the population variance or standard deviation
To solve this problem first find the perimeter of the rectangle by using the formula P= 2(L+W).
Plug in your number and you get the number 28.
Now, because Noah is putting in a post at every yard and our answer is already in yards we are done.
Noah will need 28 post to build the dog run.
P=2(8+6)
P=2(14)
P=28
Hope this helps :-)
