the slope field for the given differential equation is provided. sketch both branches of particular solution curve that passes through the point
The solution curve for the differential equation dy/dx = (y - y²) / x is plotted in the slope field.
What is a slope field?
The solutions to a scalar function's first-order differential equation are shown graphically by slope fields, also known as direction fields. Functions depicted as solid curves are solutions to a slope field. In order to determine the estimated tangent slope at a point on a curve, where the curve is some solution to the differential equation, one can use a slope field, which displays the slope of a differential equation at specific vertical and horizontal intervals on the x-y plane.
The slope field is a cartesian grid where you draw lines in various directions to represent the slopes of the tangents to the solution. Therefore by drawing a curve through consecutive slope lines, we can find a solution to the differential equation.
The differential equation is dy/dx = (y - y²) / x.
The solution curve is drawn using the solution points (1,2) for the differential equation.
Therefore, the solution curve is obtained.

Answer:

Step-by-step explanation:
The position of a particle moving along a coordinate line is s=√24+6t , with s in meters and t in seconds. Find the particle's velocity and acceleration at t=2 sec.
The correct value of particle's acceleration at t = 2 seconds is -1/12 m/s^2.
To find the particle's velocity, we need to take the derivative of the position function with respect to time (t).
Given the position function:
s = √24 + 6t
To find the velocity, we differentiate the position function with respect to time:
v = ds/dt
Applying the power rule and chain rule for differentiation, we get:
v = (1/2) * (24 + 6t)^(-1/2) * 6
Simplifying further:
v = 3 / √(24 + 6t)
To find the velocity at t = 2 seconds, we substitute t = 2 into the velocity equation:
v = 3 / √(24 + 6(2))
v = 3 / √(24 + 12)
v = 3 / √36
v = 3 / 6
v = 1/2 m/s
So, the particle's velocity at t = 2 seconds is 1/2 m/s.
Now, let's find the particle's acceleration. Acceleration is the derivative of velocity with respect to time.
a = dv/dt
To find the acceleration, we differentiate the velocity function with respect to time:
a = d(3 / √(24 + 6t)) / dt
Applying the quotient rule and chain rule, we get:
a = -3 * (24 + 6t)^(-3/2) * 6
Simplifying further:
a = -18 / (24 + 6t)^(3/2)
To find the acceleration at t = 2 seconds, we substitute t = 2 into the acceleration equation:
a = -18 / (24 + 6(2))^(3/2)
a = -18 / (24 + 12)^(3/2)
a = -18 / 36^(3/2)
a = -18 / 36^(3/2)
a = -18 / 216
a = -1/12 m/s^2
So, the particle's acceleration at t = 2 seconds is -1/12 m/s^2.

PLEASE HELP, it’s urgent
I'm using goformative to do my work, I have number 13 answer right but the rest show my answers incorrect, I will appreciate if you can help me with my question I will paste the image of the question I have.
Firstly, we will have to make a representation of the angle
We have this as follows;
As we can see, alpha added to theta is 180 degrees
Firstly, by the use of Pythagoras' theorem, we can get the value of r
r faces the right angle, and that makes it the hypotenuse
According to the theorem, the square of r, the hypotenuse equals the sum of the squares of the two other sides
Thus, we have it that;
\(\begin{gathered} r^2=(-2)^2+4^2 \\ r^2\text{ = 4 + 16} \\ r^2\text{ = 20} \\ r\text{ = }\sqrt[]{20} \\ r\text{ = 2}\sqrt[]{5} \end{gathered}\)From here, we can proceed to get the individual trigonometric ratios
a) Sine
This is the ratio of the opposite to the hypotenuse
On the second quadrant, the value of sine is positive
Thus, we have it that;
\(\begin{gathered} \sin \text{ }\alpha\text{ = }\frac{4}{2\sqrt[]{5}} \\ \alpha\text{ = }\sin ^{-1}(\frac{4}{2\sqrt[]{5}}) \\ \alpha\text{ = 63.43} \\ \theta\text{ = 180-63.43} \\ \theta\text{ = 116.57} \\ \sin \text{ 116.57 = }\frac{4}{2\sqrt[]{5}\text{ }}=\text{ }\frac{4\sqrt[]{5}}{10}\text{ = }\frac{2\sqrt[]{5}}{5} \\ \\ \sin \text{ }\theta\text{ = }\frac{2\sqrt[]{5}}{5} \end{gathered}\)b) cosine
The cosine of an angle is the ratio of the adjacent to the hypotenuse
Mathematically, we know that;
\(\begin{gathered} \cos ^2\theta+sin^2\theta\text{ = 1} \\ \cos ^2\theta=1-sin^2\theta \\ \cos ^2\theta\text{ = 1 - (}\frac{2\sqrt[]{5}}{5})^2 \\ \\ \cos ^2\theta\text{ = 1- }\frac{20}{25} \\ \\ \cos ^2\theta\text{ = }\frac{5}{25} \\ \cos ^2\theta\text{ = }\frac{1}{5} \\ \\ \cos \text{ }\theta\text{ = }\sqrt[]{\frac{1}{5}} \\ \\ \cos \text{ }\theta\text{ = -}\frac{\sqrt[]{5}}{5} \end{gathered}\)We choose the negative value for the cosine since cosine is negative on the second quadrant
c) Tan
The tan of an angle is the ratio of the opposite to the adjacent
Also, by dividing the sine of an angle by the cosine of the same angle, we can get the tan of the angle
Thus, we have it that;
\(\begin{gathered} \text{Tan }\theta\text{ = }\frac{\sin \text{ }\theta}{\cos \text{ }\theta} \\ \\ \text{Tan }\theta\text{ = }\frac{\frac{2\sqrt[]{5}}{5}}{\frac{-\sqrt[]{5}}{5}}\text{ = }\frac{2\sqrt[]{5}}{5}\times\frac{5}{-\sqrt[]{5}}\text{ = -2} \end{gathered}\)d) cosec theta
The cosec of an angle is the multiplicative inverse of the sine
Mathematically;
\(\begin{gathered} co\sec \theta\text{ = }\frac{1}{\sin \text{ }\theta} \\ \\ co\sec \text{ }\theta\text{ = }\frac{1}{\frac{2\sqrt[]{5}}{5}}\text{ = }\frac{5}{2\sqrt[]{5}}\text{ = }\frac{5\sqrt[]{5}}{10}\text{ = }\frac{\sqrt[]{5}}{2} \end{gathered}\)e) sec theta
The sec of an angle is the multiplicative inverse of the cosine of the angle
Thus, we have it that;
\(\text{sec }\theta\text{ = }\frac{1}{\cos \text{ }\theta}\text{ = }\frac{1}{-\frac{\sqrt[]{5}}{5}}\text{ = -}\frac{5}{\sqrt[]{5}}\text{ = -}\frac{5\sqrt[]{5}}{5}\text{ = -}\sqrt[]{5}\)f) cot theta
The cot of an angle is the multiplicative angle of the tan
Thus, we have it that;
\(\begin{gathered} \cot \text{ }\theta\text{ = }\frac{1}{\tan \text{ }\theta} \\ \\ \cot \text{ }\theta\text{ = }\frac{1}{-2}\text{ = -}\frac{1}{2} \end{gathered}\)Substitute the (-2+5x) for y into this equation:
-3x+6y=-12 to solve for X.
Answer:
x = 0
Step-by-step explanation:
-3x + 6(-2+5x) = -12
-3x - 12 + 30x = -12

The expected value for playing roulette if a person bet $16 on red is -$0.84.
b. The statement that best describes what this value means is option b. Over the long run, the player can expect to lose about $1.05 for each game played.
What is the expected value?To be able to calculate the expected value, you need to multiply the probability of winning by the amount won hence it will be:
Expected value = (18/38) x $16 - (20/38) x $16
= -$0.84
Based on the fact that the expected value has a negative sign, it implies that, on average, the player tend to lose money over the long run.

5. Find two equations of a circle if one of the end points of the diameter is at the origin and the
radius is 3.
Step-by-step explanation:
there are many possibilities, 4 of them really easy.
the endpoint of a diameter is simply a point on the circle arc.
the easy options are to assume that the center of the circle is on the x- or the y-axis.
let's go with the x-axis (we only need 2 circles : one with the center left, and one with the center right of the origin).
we know the radius is 3.
so, the center of either circle is 3 units away from the origin.
so, center of circle1 = (-3, 0), center of circle2 = (3, 0).
the equation for a circle is
(x - h)² + (y - k)² = r²
r is the radius, (h, k) is the center point.
equation for circle1 :
(x - -3)² + (y - 0)² = 3²
(x + 3)² + y² = 9
equation for circle2 :
(x - 3)² + (y - 0)² = 3²
(x - 3)² + y² = 9
you see ?
the other 2 easy options would be to put the centers on the y-axis : (0, -3) and (0, 3)

prove that there exist only five regular polyhedron
To prove that there are only these five regular polyhedra, we can consider Euler's polyhedron formula, which states that for any convex polyhedron, the number of vertices (V), edges (E), and faces (F) satisfy the equation V - E + F = 2.
Proving there exist Five Regular PolyhedronThe five regular polyhedra, also known as the Platonic solids, are the only convex polyhedra where all faces are congruent regular polygons, and the same number of polygons meet at each vertex.
The five regular polyhedra are:
1. Tetrahedron: It has four triangular faces, and three triangles meet at each vertex.
2. Cube: It has six square faces, and three squares meet at each vertex.
3. Octahedron: It has eight triangular faces, and four triangles meet at each vertex.
4. Dodecahedron: It has twelve pentagonal faces, and three pentagons meet at each vertex.
5. Icosahedron: It has twenty triangular faces, and five triangles meet at each vertex.
To prove that there are only these five regular polyhedra, we can consider Euler's polyhedron formula, which states that:
"for any convex polyhedron, the number of vertices (V), edges (E), and faces (F) satisfy the equation V - E + F = 2".
For regular polyhedra, each face has the same number of sides (n) and each vertex is the meeting point of the same number of edges (k). Therefore, we can rewrite Euler's formula for regular polyhedra as:
V - E + F = 2
=> kV/2 - kE/2 + F = 2
=> k(V/2 - E/2) + F = 2
Since each face has n sides, the total number of edges can be calculated as E = (nF)/2, as each edge is shared by two faces. Substituting this into the equation:
k(V/2 - (nF)/2) + F = 2
=> (kV - knF + 2F)/2 = 2
=> kV - knF + 2F = 4
Now, we need to consider the conditions for a valid polyhedron:
1. The number of faces (F), edges (E), and vertices (V) must be positive integers.
2. The number of sides on each face (n) and the number of edges meeting at each vertex (k) must be positive integers.
Given these conditions, we can analyze the possibilities for different values of n and k. By exploring various combinations, it can be proven that the only valid solutions satisfying the conditions are:
(n, k) pairs:
(3, 3) - Tetrahedron
(4, 3) - Cube
(3, 4) - Octahedron
(5, 3) - Dodecahedron
(3, 5) - Icosahedron
Therefore, there exist only five regular polyhedra.
