Population are often represented using exponential functions
The population of the bacteria on day 30 is 134837
Let x represent the number of days, and y represents the population.
So, we have: (x,y) = (1,8500), (2, 9350) (3, 10285)
An exponential functions is represented as [tex]\mathbf{y = ab^x}[/tex]
So, we have:
[tex]\mathbf{8500 = ab}[/tex]
[tex]\mathbf{9350 = ab^2}[/tex]
Divide both equations
[tex]\mathbf{\frac{9350}{8500} = \frac{ab^2}{ab}}[/tex]
[tex]\mathbf{1.1 = b}[/tex]
Rewrite as:
[tex]\mathbf{b = 1.1 }[/tex]
Substitute 1.1 for b in [tex]\mathbf{8500 = ab}[/tex]
[tex]\mathbf{ 8500 = 1.1a}[/tex]
Divide both sides by 1.1
[tex]\mathbf{ 7727.3 = a}[/tex]
Rewrite as:
[tex]\mathbf{ a = 7727.3 }[/tex]
So, we have:
[tex]\mathbf{y = ab^x}[/tex]
[tex]\mathbf{y = 7727.3 \times 1.1^x}[/tex]
On day 30, we have: x = 30.
So, the equation becomes
[tex]\mathbf{y = 7727.3 \times 1.1^{30}}[/tex]
[tex]\mathbf{y = 134837}[/tex]
Hence, the population of the bacteria on day 30 is 134837

What is Civil war?
The American Civil War, commonly referred to by other names, lasted from April 12, 1861, until May 26, 1865. The Union[f] ("the North") and the Confederacy ("the South"), the latter of which was made up of seceding states, engaged in combat.
The conflict over whether to allow slavery to spread into the western regions, creating more slave states, or to forbid it from doing so, which was widely believed to put slavery on the path to eventual extinction, was the main driver of the war.
The election of Abraham Lincoln as president of the United States in 1860 ended years of political contention over slavery because he opposed its spread into the country's western territories.
Therefore, He learned that the director had given the role to another actor archaeologist.

Answer:
C
Explanation:
is unobservable
"In the past, behaviorists were not likely to view cognition as a part of learning because cognition is unobservable." Thus, option D is correct.
What is cognition?Thinking, attention, language, learning, memory, and perception are all examples of cognitive activities that occur in the brain. These processes are not distinct talents; rather, they are a collection of interconnected abilities that enable us to function as healthy adults.
Learning, according to behaviorists, takes place mostly through observation. They thought that a person learns different parts of his or her life through observation. Imitation, modeling, and other forms of observation are all part of the observation process. Experiments on classical conditioning were used by behaviorists to illustrate that behavior is a learned process. Cognition, on the other hand, refers to the mental processes that include comprehension and knowledge.
As a result, Previously, behaviorists were unlikely to consider cognition to be a component of learning, since cognition is a mental process. Hence, option D is correct.

Explanation:
The solution of the given equation x² - 4x + 1 = 0 is;
x = 2 ± √3
We are given;
x² - 4x + 1 = 0
Using quadratic formula we have;
x = [-b ± √b² - 4ac]/2a
where;
a = 1
b = -4
c = 1
Thus;
x = [-(-4) ± √((-4)² - 4(1 * 1)]/2(1)

Answer:
Explanation:
area ABD = 16*12/2
area ABC = 9*12/2
------------------------------
so the ratio of the area ABC to the area of ABD = (9*12/2)/(16*12/2) =
= 9/16
hope this helped!
mark me brainliest :D
The ratio of the area of ABC to the area of ABD is 9/16. The correct option is B.
What is the area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.
The area of a triangle is the region bounded by its perimeter or its three sides. The area of a triangle can be calculated using the formula, where the base of the triangle is b and the height is h.
A = ½ (b × h)
The two areas will be calculated as:-
Area ABD = ( 1 / 2 ) x 16 x 12
Area ABC = (1 / 2 ) x 9 x 12
So the ratio of the area ABC to the area of ABD will be
= [ ( 1 / 2) x 16 x 12 ] ÷ [ (1 / 2 ) x 9 x 12 ]
= 9 / 16
Therefore, the area of ABC to the area of ABD is 9/16. The correct option is B.

A tube is being stretched while maintaining its cylindrical shape.
Answer:
This question is incomplete, the complete question is;
A tube is being stretched while maintaining its cylindrical shape. The height is increasing at the rate of 2 millimeters per second. At the instant that the radius of the tube is 6 millimeters, the volume is increasing at the rate of 96π cubic millimeters per second. Which of the following statements about the surface area of the tube is true at this instant? (The volume V of a cylinder with radius r and height h is V=πr2h. The surface area Sof a cylinder, not including the top and bottom of the cylinder, is S=2πrh.)
A) The surface area is increasing at the rate of 28pi square mm per second.
B) The surface area is decreasing at the rate of 28pi square mm per second.
C) The surface area is increasing at the rate if 32pi square mm per second.
D) The surface area is decreasing at the rate of 32pi square mm per second.
Answer:
Surface Area is increasing at the rate of 28π mm²/sec ( Option A )
Explanation:
Given the data in the question;
let r be the radius and h be the height of the tube
so volume V = πr²h
dv/dt = πr² dh/dt + 2nrh dr/dt
⇒ 96n = π × 36 × 2 + 2π × 6h dr/dt
⇒ 24π = 12nh dr/dt ⇒ h.dr/dt = 2
Area Surface S = 2nrh
ds/dt = 2π ( r.dh/dt + h.dr/dt )
= 2π ( 6×2 + 2)
= 2π (14)
= 28π
therefore Surface Area is increasing at the rate of 28π mm²/sec ( Option A )

What must be the value of x so that lines c and d are parallel lines cut by transversal p? 12 18 81 99.
Answer:18
Explanation:
The lines c and d are parallel if x = 18.
Hence, option B is correct.
Use the concept of an equation of line defined as:
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.
In the figure,
The corresponding angles are (3x + 45)° and 81°
The objective is to find the value such that lines c and d become parallel.
Since we know that,
The sum of angles of parallel lines passing through a common line is 180°,
Therefore,
(3x + 45)° + 81° = 180°
Simplifying like terms,
3x = 54
Divide both sides by 3,
x = 18
Hence,
The required value of x is 18 which is option B.
