Answer: 5489
Step-by-step explanation:
Given the following :
Growth rate (r) = 19% per hour
Sample culture in population = 2300
Size of sample after 5 hours =?
Using the exponential relation:
P = Po * r^t
P = population after 5 hours
Po = Initial sample population
t = time
P = 2300 * (1 +19%)^t
P = 2300 ×(1 + 0.19) ^5
P = 2300 * 1.19^5
P = 2300 * 2.3863536599
P = 5488.61341777
P = 5489 (nearest integer)

Using number line and mental mathematics, the value of u = -√25, t = - 2π, s = -√68
<h3>What is a number line?</h3>
A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present.
The usage of the number is determined by the question that it corresponds to, such as when graphing a point.
As we can observe that
All the points lie on negative axis. The value of u = -√25 = 5
t = -2π = -2×3.14 = -6.28
s = -√68 = - 8.24
