The structured activity among the given options is, "playing national level basketball." The correct option is D.

Learning exercises that are structured have a defined start, middle, and end. Every piece or type of piece has a clear function in the completion of the play activity, and there is typically a rule or set of rules.

Activities that are structured are ones that are planned, organized, and frequently include rules or guidelines.

Usually directed by a coach, instructor, or other authoritative figure, these activities have a clear goal or objective.

Swimming, biking, and doing cartwheels can all be fun and healthy activities, but they are often less regimented than sports like basketball, which require a lot of planning, organization, and coaching.

The one i am going to discuss among the  6 Discoveries in Infancy is Discovery 6 : Imitation.

Discovery 6 is known to be the steps in infancy where a child is said to  learn about how Imitation influences one's action.

In this step, in the first two years of life, the infant is known to be very good at imitating others and as such, My thought is that parents and siblings of the child need to mindful of what they do or say in their presence.

Note that Imitation is said to be a very essential learning skill and as such a child in his or her early stage of life do imitate their own behaviors and they also mimic things they see, from body activity to others.

A laughable experience is that my brother  always hear my Dad calling my Mum "my Honey, my beautiful wife. My brother ends up calling my mother the same for a while and would not stop if ask to or corrected as he believes it was right and he only stopped when he grew pass that stage. Therefore  one should know and understand that  power of imitation is strong and can influence a child positively or negatively.

Each of these ODEs is linear and homogeneous with constant coefficients, so we only need to find the roots to their respective characteristic equations.

(a) The characteristic equation for

[tex]y'' - 2y' - 8y = 0[/tex]

is

[tex]r^2 - 2r - 8 = (r - 4) (r + 2) = 0[/tex]

which arises from the ansatz [tex]y = e^{rx}[/tex].

The characteristic roots are [tex]r=4[/tex] and [tex]r=-2[/tex]. Then the general solution is

[tex]\boxed{y = C_1 e^{4x} + C_2 e^{-2x}}[/tex]

where [tex]C_1,C_2[/tex] are arbitrary constants.

(b) The characteristic equation here is

[tex]25r^2 - 20r + 4 = (5r - 2)^2 = 0[/tex]

with a root at [tex]r=\frac25[/tex] of multiplicity 2. Then the general solution is

[tex]\boxed{y = C_1 e^{2/5\,x} + C_2 x e^{2/5\,x}}[/tex]

(c) The characteristic equation is

[tex]r^2 + 2r + 2 = (r + 1)^2 + 1 = 0[/tex]

with roots at [tex]r = -1 \pm i[/tex], where [tex]i=\sqrt{-1}[/tex]. Then the general solution is

[tex]y = C_1 e^{(-1+i)x} + C_2 e^{(-1-i)x}[/tex]

Recall Euler's identity,

[tex]e^{ix} = \cos(x) + i \sin(x)[/tex]

Then we can rewrite the solution as

[tex]y = C_1 e^{-x} (\cos(x) + i \sin(x)) + C_2 e^{-x} (\cos(x) - i \sin(x))[/tex]

or even more simply as

[tex]\boxed{y = C_1 e^{-x} \cos(x) + C_2 e^{-x} \sin(x)}[/tex]

(a) This is a Bernoulli equation:

[tex]\dfrac{dy}{dx} + \dfrac{x}{2(x^2+1)} y = x^3y^5[/tex]

[tex]\implies y^{-5} \dfrac{dy}{dx} + \dfrac{x}{2(x^2+1)} y^{-4} = x^3[/tex]

Substitute [tex]z=y^{-4}[/tex] and [tex]\frac{dz}{dx} = -4y^{-5}\frac{dy}{dx}[/tex] to transform the ODE to

[tex]-\dfrac14 \dfrac{dz}{dx} + \dfrac{x}{2(x^2+1)} z = x^3[/tex]

[tex]\implies \dfrac{dz}{dx} - \dfrac{2x}{x^2+1} z = -4x^3[/tex]

which is now linear in [tex]z[/tex]. Using the integrating factor method, the I.F. is

[tex]\mu = \displaystyle \exp\left(\int -\frac{x}{x^2+1} \, dx\right) = \exp\left(-\frac12 \ln(1+x^2)\right) = \dfrac1{\sqrt{1+x^2}}[/tex]

Distribute [tex]\mu[/tex] on both sides to get a derivative of a product on the left side.

[tex]\dfrac1{\sqrt{1+x^2}} \dfrac{dz}{dx} - \dfrac{2x}{(x^2+1)^{3/2}} z = -\dfrac{4x^3}{\sqrt{1+x^2}}[/tex]

[tex]\implies \dfrac{d}{dx} \left(\dfrac1{\sqrt{1+x^2}} z\right) = -\dfrac{4x^3}{\sqrt{1+x^2}}[/tex]

Integrate both sides (the integral on the right can be done by parts) to get

[tex]\displaystyle \frac1{\sqrt{1+x^2}} z = -4 \int \frac{x^3}{\sqrt{1+x^2}} \, dx = -\frac43 (x^2-2) \sqrt{1+x^2} + C[/tex]

Solve for [tex]z[/tex].

[tex]\displaystyle \frac1{\sqrt{1+x^2}} z = -\frac43 (x^2-2) \sqrt{1+x^2} + C[/tex]

[tex]\implies z = -\dfrac43 (x^2-2) (1+x^2) + C \sqrt{1+x^2}[/tex]

Solve for [tex]y[/tex].

[tex]\dfrac1{y^4} = -\dfrac43 (x^2-2) (1+x^2) + C \sqrt{1+x^2}[/tex]

[tex]\implies \boxed{y^4 = -\dfrac3{4(x^2-2) (1+x^2) + C \sqrt{1+x^2}}}[/tex]

You could go on to solve explicitly for [tex]y[/tex] if you like.

(b) This is also a Bernoulli equation:

[tex]x^2y' + 2xy - y^3 = 0[/tex]

[tex]\implies x^2 y^{-3} y' + 2xy^{-2} = 1[/tex]

Substitute [tex]z=y^{-2}[/tex] and [tex]z' = -2y^{-3}y'[/tex].

[tex]-\dfrac{x^2}2 z' + 2xz = 1[/tex]

[tex]\implies z' - \dfrac4x z = -\dfrac2{x^2}[/tex]

Now repeat the method from (a) to solve for [tex]y[/tex].

[tex]\mu = \exp\left(-\displaystyle \int \frac4x \, dx\right) = \dfrac1{x^4}[/tex]

[tex]\implies \dfrac1{x^4} z' - \dfrac4{x^5} z = -\dfrac2{x^6}[/tex]

[tex]\implies \left(\dfrac1{x^4} z\right)' = -\dfrac2{x^6}[/tex]

[tex]\displaystyle \implies \dfrac1{x^4} z = -2 \int \frac{dx}{x^6}[/tex]

[tex]\implies \dfrac1{x^4} z = \dfrac2{5x^5} + C[/tex]

[tex]\implies z = \dfrac2{5x} + Cx^4[/tex]

[tex]\implies \dfrac1{y^2} = \dfrac2{5x} + Cx^4[/tex]

[tex]\implies \boxed{y^2 = \dfrac{5x}{2 + Cx^5}}[/tex]

So, for the formation of the solar system, a hypothesis or "theory" was made and it is called the Solar Nebula theory.

So here goes,

A vast cloud of dust once existed where our solar system is now.  Static electricity drove the particles to begin clumping together over a period of billions of years. The clumps kept expanding because of the increased gravitational attraction they had on neighboring particles as they grew bigger. Mercury through Mars are examples of heavier clumps, or those with larger amounts of heavy elements in their compositions, that eventually evolved into the inner, or rocky, planets. The outer, gaseous planets, which include Jupiter through Neptune, were formed from lighter groupings. The sun emerged as the biggest, heaviest mass of all.

The clumps, which were now the size of planets, used gravity to catch additional clumps, which developed into moons. For instance, Mars managed to snag a few asteroids. Jupiter photographed an amazing variety of bodies. However, it should be noted that the moon of Earth is assumed to have formed as a result of a large collision that sent some of the planet's mantle into space.

Although we consider our solar system to be developed, "clump capture" is still going on. The planets constantly sweep up junk in their courses as they move through space. Saturn is gradually consuming its renowned rings, meteor showers on Earth occur as we travel through debris fields, and so on.
