Answer: x = -1
Step-by-step explanation:
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: x
Step-by-step explanation:
The inverse undos any changes to x, reversing those changes will leave x. Ex: f(x)=x+2. The inverse (from replacing x with y and y with x and solving for y) is h(x)=x-2. Plugging x+2 into h(x) (composition of functions) results in x. 2 and -2 cancel out.
Answer:
z²/2
Step-by-step explanation:
The applicable properties of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)(a^c) = a^(b+c)
a^-b = 1/a^b
__

A is a compound event
b is a compound event
c is not a compound event since the coin only has 2 possibilities, if the coin is a dice or if it was removed it would be compound
