Find the circumference of the metal frame?
C = pi * d
Where 'd' is the diameter.
In this case, the diameter is 14, because that is the given information from the question.
Plug it in along with 3.14 for pi:
C = 3.14 * 14
C = 43.96
So it's approximately 44
The number of bacteria in species A at time t is given by:

.
The number of bacteria in species B at time t is given by

You are asked to find N(t) which is the difference in the species at time t. Difference refers to the answer is a subtraction problem. Thus, we are asked to find N(t) = A(t)-B(t)
We subtract and obtain:

That is,

which is the last answer choice.
With respect to notation, it is common to denote an exponent using ^. So if we want to write

we can write "(.25t)^3"
Answer:
Step-by-step explanation:
5/6 - (2/5 + 1/3)
25/30 - (12/30 + 10/30)
25/30 - 22/30 = 3/30 = 1/10
answer is b

Determine the horizontal distance
The horizontal distance is the distance between the technician and the base of the pole.
Represent this with x.
The relationship between x, 175ft and 25 degrees is represented as:
--- i.e. tan formula
Multiply both sides by x


Make x the subject



--- approximated
<em>The distance is approximately 375.3ft</em>
