The polynomial [tex]3y^2 (y 7)^ 2 - 15[/tex] after it has been fully simplified and written in standard form as [tex]4y^4 + 34[/tex].
A polynomial is an expression in mathematics that consists of variables (also known as indeterminates) and coefficients.
It involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. x2 4x + 7 is an example of a polynomial with a single indeterminate x.
A polynomial is a mathematical expression made up of indeterminates and coefficients that only involves the operations of addition, subtraction, multiplication, and positive-integer powers of variables.
To fully simplify and write the polynomial [tex]3y^2(y-7)^2 - 15[/tex] in standard form, we first need to expand the squared binomial:
[tex](y-7)^2 = (y-7)(y-7) = y^2 - 14y + 49[/tex]
Now we can substitute this expression back into the original polynomial and simplify:
[tex]3y^2(y-7)^2 - 15 = 3y^2(y^2 - 14y + 49) - 15\\= 3y^2y^2 - 42y^3 + 147y^2 - 15\\= 3y^4 - 42y^3 + 147y^2 - 15[/tex]
So the fully simplified polynomial, written in standard form, is:
[tex]3y^4 - 42y^3 + 147y^2 - 15[/tex]
Therefore, the correct answer is [tex]4y^4 + 34.[/tex]

What is geology?The main branch of Earth science, geology, studies how the earth was created, as well as its makeup and the processes that impact it. Natural humanity's field of geology is interested with Earth and other celestial objects, the structures or rocks that make them up, and also the mechanisms that cause these shifts over time.
A deposition is the act of depositing sediment that has been carried by the air, water, seas, or ice. Granules, sand, clay, and salts that have been dissolved in the water can all be used to convey sediment.
Salts could later be accumulated through evaporation or organic action. Traditionally, sedimentary rocks are found in strata known as strata. Younger layers sit on top of older levels in unbroken strata. Therefore, option C is the correct option.

In basketball, hang time is the time that both of your feet are off the ground during a jump. The equation for hang time is t = 2 (StartFraction 2 h Over 32 EndFraction) Superscript one-half , where t is the time in seconds, and h is the height of the jump, in feet. Player 1 had a hang time of 0.9 s. Player 2 had a hang time of 0.8 s. To the nearest inch, how much higher did Player 1 jump than Player 2? in.
Answer:
8in
Explanation:
edge 2020
The amount of height that player 1 jumped higher than player 2 to the nearest inch is; 8 inches
How to substitute values into an equationWe are given the hang time equation as;
t = 2(2h/32)^(½)
Where;
h is height of jump
Hang time of player 1 = 0.9 s
Hang time of player 2 = 0.8 s
Let's make h the subject of the hang time equation to get;
h = 2t²
For player 1;
h1 = 2(0.9)²
h1 = 3.24 ft
Converting to inches gives;
h1 = 38.88 inches
For player 2;
h2 = 2(0.8)²
h2 = 2.55 ft
Converting to inches gives
h2 = 30.72 inches
Difference in jump height = h1 - h2
Difference in jump height = 38.88 - 30.72
Difference in jump height ≈ 8 inches

a 15.0 kg block is attached to a very light horizontal spring of force constant 575 n/m and is resting on a smooth horizontal table (figure 1). suddenly it is struck by a 3.00 kg stone traveling horizontally at 8.00 m/s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left.
The instantaneous velocity of the 15 kg. mass just after collision can be found by the principle of linear momentum.
a) The speed of the 15 kg. just after collision is 2 m/s.
b) The type of collision is inelastic collision
c) The compression of the spring is approximately 0.323 m.
Reasons:
The given parameters are;
Mass of the block attached to the spring, m₁ = 15.0 kg
Force constant of the spring, K = 575 N/m
Mass of the stone that strikes the block, m₂ = 3.00 kg
Speed of the stone, v₂ = 8.00 m/s
Speed with which the stone rebounds, v₃ = 2.00 m/s
a) The total initial momentum = 3 kg. × 8 m/s = 24 kg·m/s
The final momentum, just after collision = 3 × (-2) kg·m/s + 15 kg ×v₁
By conservation of momentum, we have;
24 kg·m/s = 3 × (-2) kg·m/s + 15 kg ×v₁
[tex]v_1 = \dfrac{24 \, kg \cdot m/s + 6 \, kg \cdot m/s}{15 \, kg} = 2 \, m/s[/tex]
The speed of the 15 kg. just after collision, v₁ = 2 m/s.
b) A collision is elastic when the kinetic energy of the collision is conserved
The initial kinetic energy, K.E.₁ = 0.5 × 3 kg. ×(8 m/s)² = 96 J
The sum of the final kinetic energy are;
0.5 × 3 kg. × (2 m/s)² + 0.5 × 15 kg × (2 m/s)² = 36 J
The initial kinetic energy ≠ The final kinetic energy
Therefore, the collision is not elastic
(c) The kinetic energy given by the block = The elastic potential energy gained by the spring
Kinetic energy of the block, K.E. = 0.5 × 15 kg × (2 m/s)² = 30 J
Elastic energy gained by the block = 0.5 × K × x² = 0.5 × 575 N/m × x²
Therefore;
0.5 × 575 N/m × x² = 30 J
[tex]x^2 = \dfrac{30 \, J}{0.5 \times 575 \, N/m} = \dfrac{12}{115} \, m^2[/tex]
[tex]x = 2 \cdot \sqrt{\dfrac{3}{115} } \approx 0.323[/tex]
The compression of the spring, x ≈ 0.323 m.

write two to three sentences explaining the pun on the name ernest in the passage and how the pun connects to a serious issue or question.
Answer:
Throughout the play, Wilde uses puns to connect the name Ernest to the word earnest. When Cecily says that she has always wanted to marry someone named Ernest, she implies that she also wants someone earnest who “inspire[s] absolute confidence.” In this scene, however, Algernon is lying to her about who he is. His deception suggests that no one can ever have “absolute confidence” that others are being earnest.
Explanation:
Wilde utilizes puns throughout the play to tie the name Ernest to the term earnest.
The Importance of Being Earnest:Ernest is a given name that is derived from the word earnest. The term earnest refers to sincerity, yet Ernest in "The Importance of Being Earnest" is anything but.
Ernest adopts many identities or occupations, but none of them are authentic since he isn't himself. Finally, he understands why it is critical to be "honest" and loyal to himself. At the end of the novel, being "earnest" and being "Ernest" have the same meaning, since the main character, Ernest, learns the significance of being true to oneself.

The zebra mussel is an invasive species that decrease the carrying capacity of native species by competing for limited food resources. Invasive species are harmful to the homeostasis of an ecosystem.
The carrying capacity refers to the maximum population size of a species sustained by specific environmental conditions.
The factors that affect the carrying capacity include the availability of both biotic (e.g., food, presence of invasive species, etc) and abiotic (e.g., water, habitat) resources.

which statement best explains the difference between polar and nonpolar covalent bonds?
Answer:
Nonpolar covalent bonds involve two atoms that have equal electonegativity whereas polar covalent bonds involve two atoms that are unequal in their electronegativity.
Explanation:
Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.
A covalent bond is a force that joins two atoms of non-metallic elements to form a molecule. Atoms share pairs of electrons from their most superficial layer (called the valence layer) to achieve the stability of the molecule that has been formed with the bond and thus comply with the octet rule.
On the other side, electronegativity refers to the tendency of the atom of a given element to attract electrons.
So, the covalent bond between two atoms can be polar or nonpolar.
Polarity depends on the difference in electronegativity of the joining elements. The greater the electronegativity difference, the greater the polar character of the bond. The most electronegative element will be the one that most strongly attracts the shared electrons, then a negative partial charge will be generated on said element, while a positive partial charge will be generated on the other element (less electronegative).
Finally, nonpolar covalent bonding occurs when pairs of electrons are shared between atoms that have the same or very similar electronegativity, favoring an equitable distribution of electrons.
In summary, the correct answer is: Nonpolar covalent bonds involve two atoms that have equal electonegativity whereas polar covalent bonds involve two atoms that are unequal in their electronegativity.
