Exponential growth is a pattern of data that shows sharper increases over time. In finance, compounding creates exponential returns. Savings accounts with a compounding interest rate can show exponential growth.
One of the best examples of exponential growth is observed in bacteria. It takes bacteria roughly an hour to reproduce through prokaryotic fission. If we placed 100 bacteria in an environment and recorded the population size each hour, we would observe exponential growth
First, population size is influenced by the per capita population growth rate, which is the rate at which the population size changes per individual in the population. This growth rate is determined by the birth, death, emigration, and migration rates in the population.

Exponential growth depends on the per capita growth rate (rmax) of a population gradually increasing over time.
The given statement is false.
Exponential growth is a continuous boom or lower in a populace in which the price of change is proportional to the range of people at any given time.
It is growth that maintains acceleration with time and is a J-shaped curve. The intrinsic price of an increase in a populace is calculated by including the dying rate and the birth price.
Divide both sides by N and you get the growth rate per number of individuals ("per capita"): Because r = rmax [1-(N/K)] in the logistic model, we can substitute r: Thus, r equals the per capita growth rate.

Which exponential function has a faster rate f(x)=5^x or g(x)=(1/3)^x. How do you know?
Answer:
f(x)
Step-by-step explanation:
This question isn't to difficult, since all you need to know is: [tex](\frac{a}{b})^x=\frac{a^x}{b^x}[/tex]. If the you're not quite sure why this is true, I'll try to express this in another way. [tex](\frac{a}{b})^x=\frac{a}{b}*\frac{a}{b}*\frac{a}{b}...\text{ x amount of times}[/tex], and as you may know when multiplying fractions, you simply multiply the numerators by the numerators and the denominators by the denominators, this means that you can simplify it to: [tex]\frac{a*a*a...\text{ x amount of times}}{b*b*b...\text{ x amount of times}}[/tex] this is literally what an exponent is which is why you can distribute the exponent as such: [tex](\frac{a}{b})^x=\frac{a^x}{b^x}[/tex]. The next thing you need to know is that: [tex]1^x=1[/tex] for any real number. This is you can express this as: [tex]1*1*1...\text{ x amount of times} = 1[/tex], since 1 times 1 times 1, will always remain 1. You may think this will not apply for rational exponents, but it still does since: [tex]1^{\frac{a}{b}}=\sqrt[b]{1}^a[/tex], and no matter what b is, it's going to be 1. The square root of 1, is 1..., the cube root of 1 is 1.... This is because the very definition of a radical is what number times times it self index amount of times is equal to the number under the radical, and no matter how many times you multiply 1, you're going to get 1. If that's a bit confusing what I'm saying is: [tex]\sqrt[n]{b}\implies\text{?}^n=b[/tex].
Anyways hopefully you understand that, if not I'm sorry if I went a bit overboard trying to explain it. Anyways all you need to really know is that: [tex](\frac{1}{3})^x=\frac{1^x}{3^x}=\frac{1}{3^x}[/tex]. So this means as x increases, all you're really doing is increasing the denominator which is decreasing the number. The f function has an integer as a base, so the function will overall be increasing. This is not true for g(x) since as x increases the y-value decreases. So this means that f(x) has a faster rate. This is because the g(x) has a horizontal asymptote, since as x approaches infinity, g(x) approaches 0, since the denominator is increasing towards infinity. So the rate of change will be slowing down as x increases, since there is only so much the g(x) can change, since it has a horizontal asymptote. This is not true for f(x) as it has no horizontal asymptote and just goes towards infinity. So the f(x) has a faster rate.
The lengths of the sides of triangle XYZ are written in terms of the variable m, where m ≥ 6.
Triangle X Y Z is shown. The length of side X Y is m + 8, the length of side Y Z is 2 m + 3, the length of side Z X is m minus 3.
Which is correct regarding the angles of the triangle?
mAngleX < mAngleZ < mAngleY
mAngleY < mAngleZ < mAngleX
mAngleY < mAngleX < mAngleZ
mAngleZ < mAngleY < mAngleX
Answer:
Option (2)
Step-by-step explanation:
The angle opposite the shortest side is the smallest and the angle opposite the longest side is the largest.
Since m is greater than or equal to 6, we know that:
2m+3 > m+8 > m-3
To get from his house to the lecture hall at school, Lin walked west 651 feet. After class, he walked northeast 910 feet to the gym. Finally, he walked 615 feet back to his house from the gym.
A triangle has points gym, Lin apostrophe s house, and lecture hall. The distance between the lecture hall and gym is 910 feet. The distance between the gym and Lin apostrophe s house is 615 feet. The distance between the lecture hall and Lin apostrophe s house is 651 feet.
What general direction did Lin walk from the gym to his house, and what type of triangle did his walking path form?
Lin walked south, creating a right triangle.
Lin walked southwest, creating an obtuse triangle.
Lin walked southeast, creating an acute triangle.
Lin walked directly east, creating a right triangle.
The general direction that Lin walked from the gym to his house is; B: Lin walked southwest, creating an obtuse triangle.
How to interpret distance bearing?
We are given;
Distance between the lecture hall and gym = 910 feet.
Distance between the gym and Lin apostrophe's house = 615 feet.
Distance between the lecture hall and Lin apostrophe's house = 651 feet.
Now, since this 3 distances form a triangle and the 3 distances are unequal, then we can call it an obtuse triangle since he walked west and then walked northwest.
Now, since he walked back to his house from the gym, we can say that he walked southwest if we picture the bearing of his first two directions.

19. What is the coordinate for the vertex of the function f(x)=-16x² + 64x?
Answer:
vertex = (2, 64 )
Step-by-step explanation:
given a parabola in standard form
f(x) = ax² + bx + c ( a ≠ 0 ) , then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
f(x) = - 16x² + 64x ← is in standard form
with a = - 16, b = 64, c = 0 , then
x = - [tex]\frac{64}{-32}[/tex] = 2
substitute x = 2 into f(x) for corresponding y- coordinate
f(2) = - 16(2)² + 64(2) = - 16(4) + 128 = - 64 + 128 = 64
vertex = (2, 64 )

Applying the vertical angles theorem, the measure of VU is determined as: 64°.
What is the Vertical Angles Theorem?If two angles lie directly opposite each other, they are vertical nagles and are therefore equal.
13x = 15x - 8 [vertical angles theorem]
13x - 15x = - 8
-2x = -8
x = 4
Let y represent m(VU). Since m(RV) = m(VU), therefore:
13x + 2y = 180 [angles on a straight line]
Plug in the value of x
13(4) + 2y = 180
52 + 2y = 180
2y = 180 - 52
2y = 128

Find the volume of the prism.
Answer:
216kmStep-by-step explanation:
The formula for finding the volume of a triangular prims is:
0.5 * b * h * length, where b is the length of the base of the triangle, h is the height of the triangle and length is prism length.
So, let's substitute those variables with the base length, height length, and prism length
The base length is 6km, the height length is 8km, and the prism length is 9km
So, we get:
0.5 * 6 * 8 * 9
= 1/2 * 6 * 8 * 9
= 1/2 * 48 * 9
= 1/2 * 432
= 216
The volume of this prism is 216km.
