Pengelola layanan air minum di desaku membuat tempat penampungan air di dataran tinggi agar air dapat menjangkau seluruh desa. Tempat penampungan tersebu berbentuk kubus dengan panjang rusuk 8 meter. Jika tempat penampungan itu penuh, berapa liter air yang tertampung?
Answer:
The shelter can contain 512 cubic meters of water.Step-by-step explanation:
This question can be translated to:
"The manager of the drinking water service in my town creates a water tank in the highlands so that the water can reach the entire town. The cube-shaped shelter is 8 meters long. If the shelter is full, how many liters of water can it contain?"
As you can observe, the volumetric form is a cube with 8 meters long each edge.
We know the volume of a cube is defined as
\(V=l^{3}\)
Where \(l=8 \ m\), replacing this value, we have
\(V=(8 \ m)^{3} \\V=512 \ m^{3}\)
Therefore, the shelter can contain 512 cubic meters of water.
The following represents a sequence with an exponential pattern. FInd the missing numbers of the sequence.
20, __, __, __, 12, 500
The complete sequence is:
20, 0.6, 41.6667, 69.4444, 12, 500.
To find the missing numbers in the given sequence, let's analyze the pattern and fill in the gaps.
Looking at the sequence, we can observe that there is an exponential pattern occurring.
Let's break it down step by step:
Starting with the first number, 20, we can see that each subsequent number is decreasing or increasing exponentially.
If we divide the second number by the first number, we get 12/20 = 0.6. Similarly, dividing the third number by the second number gives us 500/12 = 41.6667.
We can see that there is a decreasing exponential pattern from the first to the third number.
Let's continue this pattern:
If we divide the fourth number by the third number, we get an approximate value of 41.6667/0.6 = 69.4444.
So, we can deduce that the missing numbers in the sequence are approximately 0.6, 41.6667, and 69.4444.

consecutive congruent sides what does that mean give simple definition
Consecutive congruent sides refer to adjacent sides in a geometric shape that have equal lengths, creating a pattern of repetition within the shape.
consecutive congruent sides indicate that there are two sides of a shape that are next to each other and have equal lengths. This means that the lengths of these sides are identical, creating a pattern of repetition within the shape.
let's consider a triangle as an example. If a triangle has consecutive congruent sides, it means that two sides of the triangle that are next to each other have the same length. This creates a situation where the triangle has two equal-length sides that are adjacent to each other, while the remaining side can have a different length. Similarly, in other polygons or shapes, consecutive congruent sides follow the same principle of adjacent sides having the same length.
Overall, consecutive congruent sides highlight a pattern of equality and repetition in the lengths of adjacent sides within a geometric shape

When you listen to the sound of a bouncing ping-pong ball that has been dropped onto a cement floor, what mathematical pattern do you hear? Explain,
A drop of water is denser than a ping-pong ball.
Usually, water is made of particles that are firmly pressed together. In differentiation, plastic (the material ping pong balls are made of) may be a lightweight fabric and the particles are not as firmly stuffed together.
The thickness of a ping pong ball is 0.0840 g/cm³, though water’s thickness is 997 kg/m³. Subsequently, ping pong balls aren’t about as thick as water and will continuously coast and surface greatly quickly.
The ping pong ball appears to oppose gravity and coast within the air.
Ping-pong balls drift within the water since they are amazingly lightweight, empty, and filled with air. Too, the water’s surface pressure makes it simple for the ping pong ball to drift.
In expansion, water is denser than ping pong balls, making them look for the most noteworthy point of water.

There are no sign changes in the first column of the Routh array, therefore the system is stable.
Given: Characteristic equation for system `(a)`: 12s⁵ + 4s⁴ + 6s³ + 2s² + 6s + 4 = 0
Characteristic equation for system `(b)`: 12s⁵ + 8s⁴ + 18s³ + 12s² + 9s + 6 = 0
To determine the stability of the systems with the given characteristic equations, we need to find out the roots of the given polynomial equations and check their stability using Routh-Hurwitz criteria.
To find out the stability of the system with given characteristic equation, we have to check the conditions of Routh-Hurwitz criteria.
Let's discuss these conditions:1. For the system to be stable, the coefficient of the first column of the Routh array must be greater than 0.2.
The number of sign changes in the first column of the Routh array represents the number of roots of the characteristic equation in the right-half of the s-plane.
This should be equal to zero for the system to be stable.
There should be no row in the Routh array which has all elements as zero.
If any such row exists, then the system is either unstable or marginally stable.

find the points on the ellipse 3x2 2y2=1 where f(x,y)=xy has its extreme values.
The extreme values of f(x, y) = xy occur at the points (2, 1) and (-2, -1) on the ellipse \(3x^{2} +2y^{2} =1\).
To find the extreme values of f(x, y) = xy on the ellipse \(3x^{2} +2y^{2} =1\), we can use the method of Lagrange multipliers.
Define the function g(x, y) = \(3x^{2} +2y^{2} -1\). We need to find points (x, y) where the gradient of f is proportional to the gradient of g:
∇f = λ∇g
The gradient of f is ∇f = (y, x), and the gradient of g is ∇g = (6x, 4y). Therefore, we have the following system of equations:
y = 6λx
x = 4λy
Substitute the second equation into the first:
y = 6λ(4λy)
y = \(24λ^{2y}\)
If y ≠ 0, then 1 = \(24λ^{2}\), and λ = ±1/2. Plugging this value into the second equation gives x = ±2. Thus, we have two potential extreme points: (2, 1) and (-2, -1).
Now consider the case when y = 0. The constraint equation becomes \(3x^{2} =1\), and x = ±1/√3. However, these points correspond to f(x, y) = 0, which is not an extreme value.
Therefore, the extreme values of f(x, y) = xy occur at the points (2, 1) and (-2, -1) on the ellipse \(3x^{2} +2y^{2} =1\).

a) Doubling time of the population.
Initial population = 4
Doubling = 2 x 4 = 8
\(8=4e^{0.03t}\)Then, solve for t:
\(\begin{gathered} \frac{8}{4}=\frac{4e^{0.03t}}{4} \\ 2=e^{0.03t} \end{gathered}\)Apply the exponent laws:
\(\begin{gathered} \ln 2=0.03t \\ \frac{\ln2}{0.03}=\frac{0.03t}{0.03} \\ t=23.1\approx23 \end{gathered}\)Answer a: 23 years
b) Initial population = 4
Triple the population = 3 x 4 = 12
Therefore:
\(\begin{gathered} 12=4e^{0.03t} \\ \frac{12}{4}=\frac{4e^{0.03t}}{4} \\ 3=e^{0.03t} \\ \ln 3=0.03t \\ \frac{\ln 3}{0.03}=\frac{0.03t}{0.03} \\ t=36.6\approx37 \end{gathered}\)Answer b: 37 years
c) Initial population = 4
Quadruple the population = 4 x 4 = 16
So:
\(\begin{gathered} 16=4e^{0.03t} \\ \frac{16}{4}=\frac{4e^{0.03t}}{4} \\ 4=e^{0.03t} \\ \ln 4=0.03t \\ \frac{\ln 4}{0.03}=\frac{0.03t}{0.03} \\ t=46.2\approx46 \end{gathered}\)Answer c: 46 years
: A spherical scoop of vanilla ice cream sits on top of a waffle cone. The diameter of the ice cream sphere is 10 cm while the waffle cone has a diameter of 10 cm at the top and a height of 20 cm. If the ice cream melts at rate of 1.08 cm per second and drips to the waffle cone, how fast is the height of melted ice cream in the cone rising when the cone is 10% full? CHOICES: 0.41 mm per second 1.22 mm per second 1.62 mm per second 0.64 mm per second O
The correct answer is 1.22 mm per second. The height of the melted ice cream in the cone is rising at a rate of 1.22 mm per second when the cone is 10% full.
This is because the volume of the melted ice cream is increasing at a rate of 1.08 cm per second, and the volume of the cone is 125π cm3. The height of the melted ice cream is therefore rising at a rate of 1.08 cm/s / 125π cm3 = 1.22 mm/s.
The volume of the melted ice cream is increasing at a rate of 1.08 cm per second because the ice cream is melting at a rate of 1.08 cm per second. The volume of the cone is 125π cm3 because the cone has a radius of 5 cm and a height of 20 cm.
The height of the melted ice cream is therefore rising at a rate of 1.08 cm/s / 125π cm3 = 1.22 mm/s.
