Explain the difference between exponential growth and exponential decay
Final answer:
Exponential growth occurs when a population increases at an increasing rate, whereas exponential decay involves a decrease at a rate proportional to the current size. Logistic growth, adding the concept of carrying capacity, more accurately reflects natural populations with initial exponential increase followed by a plateau as resources become limited.
Explanation:
The key difference between exponential growth and exponential decay lies in the direction and rate at which a quantity changes over time. Exponential growth occurs when a population grows at an increasing rate as time passes, often depicted as a J-shaped curve, whereas exponential decay describes a process of decrease at a rate proportional to the current value, leading to a rapid reduction in size or quantity over time.
In the context of biology and population growth, exponential growth describes how populations can grow dramatically when there are no limits to resources or space. This type of growth can be formalized as a mathematical model where the population after n time periods has increased by a factor of 2n when the base growth rate is 2. In natural populations, this is idealized and does not usually last long as resources become depleted and other limiting factors come into play. On the other hand, exponential decay in biology might refer to the rapid loss of a population due to harsh conditions, lack of resources, or other negative impacts.

Find the number of hours it would take to drive 510 miles at 55 mph. Round to the nearest tenth of an hour. i THINK ITS 9.3 BUT IM NOT SURE?
Answer: It would take 9.3 hours to take 510 miles.
Step-by-step explanation: We are given to find the number of hours it would take to drive 510 miles at 55 mph.
We will be using the UNITARY method to solve the given problem.
According to the given information, we have
Number of hours taken to drive 55 miles = 1 hour.
So, number of hours taken to drive 1 mile will be
[tex]\dfrac{1}{55}~\textup{hour}.[/tex]
Therefore, the number of hours it would take to drive 510 miles is given by
[tex]\dfrac{1}{55}\times510=\dfrac{102}{11}=9.27~\textup{hour}.[/tex]
Rounding to nearest tenth of an hour, we get
9.27 hour ≈ 9.3 hour.
Thus, it would take 9.3 hours to take 510 miles.
Based on a poll, 5050% of adults believe in reincarnation. assume that 44 adults are randomly selected, and find the indicated probability. complete parts (a) through (d) below.
a. what is the probability that exactly 33 of the selected adults believe in reincarnation? the probability that exactly 33 of the 44 adults believe in reincarnation is
To solve this problem, we use the formula for binomial probability:
P = [n! / (n – r)! r!] p^r * q^(n – r)
where,
n = total number of adults = 4
r = number of adults who believe in reincarnation = 3
p = chance of believing in reincarnation = 50% = 0.50
q = 1 – p = 0.50
P = [4! / (4 – 3)! 3!] 0.50^3 * 0.50^(4 – 3)
P = 0.25 = 25%
Answer:
Answer is 0.096
Step-by-step explanation:
Here 44 adults are randomly selected.
Each adult selected is independent of the other to believe in reincarnation.
Also there are only two outcomes, probability for success in each trial = 0.50
Hence X no of adults who believe in reincarnation is binomial with n =50 and p = 0.50
[tex]a) P(X=23) = 50C23 (0.5)^{50} =0.096[/tex]
Working notes:
50C23 =108043253365600
0.5^50) = 8.8178x10^(-14)
Simplifying we get answer as 0.096
How does the radius of a positive and negative ion compare to a neutral atom?
A neutral atom contains equal amount of proton and electron.
A negative ion contains extra electrons hence there is additional outer shell so it is expected that the radius is bigger than that of a neutral atom.
While a positive ion contains less electron so there is less outer shell so the radius is smaller than that of a neutral atom.
Arranging the radius in increasing order:
positive ion, neutral atom, negative ion

5:D19, as of 2019
Step-by-step explanation:
Answer:
The correct option is C) [tex]y=\frac{2}{x-3}-6[/tex]
Step-by-step explanation:
Consider the provided information.
Transformation:
The graph of parent function f(x) move up b unit for f(x)+b.
The graph of parent function f(x) move down b unit for f(x)-b.
The graph of parent function f(x) move left b unit for f(x+b).
The graph of parent function f(x) move right b unit for f(x-b).
Since, the graph of the parent function moves down, Therefore Option Option B and D are incorrect.
Here, we can observe that vertical asymptote shifted from x = 0 to x = 3.
Horizontal Shift: Right 3 Units
Vertical Shift: Down 6 Units
Therefore, the correct option is C) [tex]y=\frac{2}{x-3}-6[/tex]

to construct the midpoint of a segment, fold the paper so that the given line segment lies on itself and
Answer:
The endpoints of the line segment lie on each other
Explanation
To understand the question, follow the practical steps below
1. Take a sheet of plane paper
2. Label the edges of the top of the paper A and B
3. Fold the paper in such a way that edge A lies on B.
You'll notice the following;
1. The top of the paper lies in itself; hence, we can say that the line segment lies on itself
2. You have a new line at the centre of the paper. The point at the top of this center line is the midpoint of the line segment
3. The edges that lie on each other translates to the endpoints lying on each other.
Number (3) above is the required observation and the right answer.

South of the White House in Washington, D.C., is the President’s Park South, or the Ellipse, which hosts events such as the White House Garden Tours. The Ellipse is 880 ft from north to south and 1057 ft from east to west. Write an equation in standard form for the Ellipse, centered at the origin.
Note: If any values of a2 or b2 are greater than 1,000, include the comma.
Given the dimensions of the Ellipse, the major axis is the east-west distance (1057 ft) and the minor axis is the north-south distance (880 ft). Taking half these lengths as 'a' and 'b' respectively, the equation of the ellipse in standard form centered at the origin is (x^2/(528.5^2)) + (y^2/(440^2)) = 1.
Explanation:The given dimensions of the Ellipse represent the lengths of the major and minor axes. In an ellipse centered at the origin, the equation in standard form is given by:
(x^2/a^2) + (y^2/b^2) = 1
where 'a' is half the length of the major axis and 'b' is half the length of the minor axis. Here, since the measurement from east to west (1057 ft) is greater than the measurement from north to south (880 ft), 'a' will have a value of 1057/2 and 'b' will have a value of 880/2. Consequently, the ellipse equation would be:
(x^2/(528.5^2)) + (y^2/(440^2)) = 1

Yolanda is saving money to buy a game. so far she has saved $30 , which is five-sixths of the total cost of the game. how much does the game cost?
Final answer:
To find the total cost of the game based on Yolanda's savings of $30, which is five-sixths of the cost, multiply $30 by the reciprocal of 5/6, resulting in a total cost of $36.
Explanation:
The question asks how much a game would cost if Yolanda has already saved $30, which is five-sixths of the total cost of the game. To find the total cost of the game, we consider the amount saved ($30) as five-sixths of the total cost (which we'll call x).
So the equation to solve is 5/6 * x = $30. To find x, we divide $30 by 5/6, which is the same as multiplying $30 by the reciprocal of 5/6 (which is 6/5). Therefore, x = $30 * (6/5) = $36. Thus, the total cost of the game is $36.

Which list contains ONLY rational numbers?
Answer:
B. [tex]0.4166\overline{6}[/tex], [tex]\sqrt{81}[/tex], [tex]\frac{1}{8}[/tex].
Step-by-step explanation:
We are asked to find the list that contains only rational numbers.
We know that a number is known as rational, when it can be expressed as a fraction.
Upon looking at our given choices, we can see that option B is the correct choice.
In [tex]0.4166\overline{6}[/tex], the digit 6 has a bar on it, this means that it is repeating. We know that a repeating decimal is a rational number.
[tex]\sqrt{81}=9[/tex]. We can represent 9 as a fraction: [tex]\frac{9}{1}[/tex].
[tex]\frac{1}{8}[/tex] is already written as a fraction, therefore, it is a rational number.
