The formula for finding the number of bacteria present is given by P=P0(10)t where P is the final population, P0 is the initial

population and t is the time measured in hours. If the population contained 275 bacteria at t = 0, approximately how long will it take for 15,000 bacteria to be present?

Answer:

5.45 hours.

Step-by-step explanation:

The formula =

P = P0(10)t

In this circumstance, P0 = 275, P = 15,000 and t = ?

Applying the values into the formula:

P = P0(10)t

15,000 = 275 × (10) × t

15,000 = 2750t

t = 15,000/2750

t = 5.45 hours

Answer:

The coordinates of the point that is a reflection of Y(-4, -2) across the x-axis are ( -4,2).

The coordinates of the point that is a reflection of Y across the y-axis are ( 4,-2).

Step-by-step explanation:

<em>Reflection across x-axis</em>

<em>The rule used for Reflection across x-axis is that y-coordinate becomes negated while x coordinate remains same.</em>

So,

The coordinates of the point that is a reflection of Y(-4, -2) across the x-axis are ( -4,2).

Because according to definition, x-coordinate remains same, while y-coordinate is negated. So x-coordinate = -4, y-coordinate = 2

<em>Reflection across y-axis</em>

<em>The rule used for Reflection across y-axis is that x-coordinate becomes negated while y coordinate remains same.</em>

So,

The coordinates of the point that is a reflection of Y across the y-axis are ( 4,-2).

Because according to definition, y-coordinate remains same, while x-coordinate is negated. So x-coordinate = 4, y-coordinate = -2
