Answer:

y = 3x + 4

Step-by-step explanation:

The line passes through points (-3, -5) and (0, 4)

The slope of the line = change in y-axis ÷ change in x-axis

i.e the slope = \frac{4 - -5}{0 - -3} = \frac{9}{3} = 3

Taking another point (x, y) on the line,

The slope = \frac{y - 4}{x - 0} = 3

Simplifying the equation above gives;

y - 4 = 3x

y = 3x + 4 (equation of the line)

A population of bacteria begins with 1500 bacteria and grows to 4500 in one hour.
dezoksy [38]

The function that represents the growth of this culture of bacteria as a function of time is; P = 1500e^(1.0986t)

<h3>How to calculate Exponential Growth?</h3>

The formula for exponential growth is;

P = P₀e^(rt)

where;

P = current population at time t

P₀ = starting population

r = rate of exponential growth/decay

t = time after start

Thus, from our question we have;

4500 = 1500 * e^(r * 1)

4500/1500 = e^r

e^r = 3

In 3 = r

r = 1.0986

Thus, the function that represents the growth of this culture of bacteria as a function of time is;

P = 1500e^(1.0986t)

For the culture to double, then;

P/P₀ = 2. Thus;

e^(1.0986t) = 2

In 2 = 1.0986t

t = 0.6931/1.0986

t = 0.631 hours
