Answer:
The correct option is D.
Step-by-step explanation:
In a linear function the rate of change is constant. It means either the function increase by a constant rate or function decrease by a constant rate.
In an exponential function the rate of change is not constant.
It is given that the population of bacteria increases by 30 every hour.
Since the population of bacteria increases by a constant rate therefore the population function is linear and it is defined as
Where P₀ is initial population and t is time in hours.
Therefore correct option is D.

The approximate age of a woman whose normal systolic pressure measures 125 mm Hg is 31
The function is given as:
When the normal systolic pressure is 125, it means that:
So, we have:
Subtract 125 from both sides of the equation
Rewrite the equation as:
Using a graphing calculator, we have:
But age cannot be negative.
So, we have:
Approximate
Hence, the age of the woman is 31

Answer:
The answer is below
Step-by-step explanation:
From the graph, we can see that both segment 1 and segment 2 are positive slopes (as the time increases, the number of people increases)
Segment 1 is more steep than segment 2 (the number of people increases in segment 1 more than segment 2). This means that the number of people entering the arena in segment 1 was higher than the rate of people entering the arena in segment 2.
