The approximate number of bacteria after 7 hours is 1082.
We are given with the situation of bacteria multiplying into colonies.
We are given also with the function of B(t)= 4e^0.8t
where t is the time of multiplication.
A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.
We just have to substitute the given time of 7 hours to find teh final count.
The answer is approximately 1082.
Therefore the correct option is B.

y ≥ 0
y > 2
y ≥ 2
The range of the function f(x) : is y > 0.
The correct option is (A)
The definition of range is the set of all possible values that the function will give when we give in the domain as input.
Given function is :
If we draw the graph for this, then we can see that the horizontal asymptote is 0.
So, the range is real numbers higher than 0.
Hence, the range should be y > 0.

Answer:
$4.69
Step-by-step explanation:
$1.62/lb×2.5=$4.05
$0.48/lb×11/3=$0.64
$4.05+$0.64=$4.69
