It is in relation to newtons law of cooling and I have to fill in a chart where t is time in seconds, T(t) is the temp of the object
and Ta is the ambient temp
t=0 T(t)= 96.41 Ta= 26.1

I have to fill in the rest which is

T(t) - Ta
which would = 70.31

ln(T(t) - Ta)
which would = aprox 4.253

but then it asked for
delta T(t)

I don't know what to do here, I know delta generaly refers to the difference of something but Im stumped by this one.

I've been told that E. coli's circular chromosome has 4.6 million base pairs. If the entire chromosome were expanded, as when a cell is lysed, and all kinks and twists were removed, how long would it be in centimeters or inches?

I need to put up deer fencing around individual fruit trees. How much fencing do I need to buy? I plan to put up three posts in an equilateral triangle around each tree. If the posts are 4 feet apart, and I string chicken wire in a circle around them, what length of fence do I need for each tree? That is, if I make an equilateral triangle with sides of length 4, what is the circumference of the circle that I would draw around the triangle?

Suppose I need to change the lenght of the sides to 3 feet or 5 feet? What is the general procedure/formula for calculating the circumference of such a circle? How do I calculate the diameter of the circle, based on the length of the sides of the equilateral triangle?
