Janet wants to solve the equation. What should she multiply both sides of the equation by? y y2 – 1 y + 1 y2 + y + 2
Answer:
B.) y^2-1
Explanation:
honest answer:)
Janet can multiply both the sides by y^2-1.
What is Equation?The numbers on either side of the equal sign in an equation are equal. That is the definition of an equation in mathematics, but an equation can also be used to describe a variety of challenges, situations, or efforts to solve an issue.
The word "equa" that starts the equation is likely already recognizable to you from words like "equal," "equality," and "equate." Making things balance out is the meaning behind each of these words.
A assertion of the equality of two quantities is expressed via an equation. Even if the equation is not mathematical but rather, let's say, interpersonal, you could still attempt to balance the two sides.
Therefore, Janet can multiply both the sides by y^2-1.

A buffer solution is made up of acetic acid (ch3cooh) and sodium acetate (nach3coo). The major equilibria in the buffer system are represented above. Which of the following equilibria could be used to support the claim that the addition of a small amount of naoh to the buffer will result in only a very small change in ph?
The equilibria showing how the acetate buffer adjusts to addition of a small amount of NaOH is:
CH₃COOH (aq) + H₂O (l) → H₃0+ (aq) + CH₃COO (aq)
What is a buffer?A buffer is defined as a solution that resists changes to its pH when little quantity of strong base or acid is added to it.
Buffers are typically made from solutions of weak acids and their salts or weak bases and their salts.
The equilibria showing how a buffer made from acetic acid and sodium acetate (NaCH3COO) adjusts to addition of a small amount of NaOH is as follows:
CH₃COOH (aq) + H₂O (l) → H₃0+ (aq) + CH₃COO (aq)
This is because when NaOH which is a strong base is added, by neutralization action, it will neutralize the hydronium ion which will make the acetic acid ionization equilibrium to shift to the right to produce more of the acetate ion, the conjugate base.

Kimberly has seven colors of lanyards. she uses three different colors to make a key chain. how many different combinations can she choose?
The number of different combinations can she choose is; 210.
What is the permutation?
We are told that;
Number of colors of Lanyards she has = 7
Number she wants to use to make a key chain = 3 colours
Thus, number of different combinations can she choose is gotten through permutation formula;
P(n, r) = n!/(n - r)!
P(7, 3) = 7!/(7 - 3)!
P(7, 3) = 210
Thus, the number of different combinations can she choose is 210.

Which stage is the last stage of speciation? question 5 options: the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations successfully interbreed. The populations become totally separated from one another. The populations are isolated and thus do not interbreed
Answer:
D) The population become adapted to different environments and eventually becomes so different that they cannot interbreed to produce fertile offspring.
Explanation:
Speciation is divided into three stages:
a) Separation.
b) Adaptation.
c) Reproductive Isolation.
Stage 1: Separation.
A part of the population separates and adapts to a new environment. Natural events such as tsunamis, tidal waves can cause organisms to separate from their initial habitat to a new environment.
Stage 2: Adaptation.
At this stage, the organisms evolve new traits that enable them to a new environment. They possess certain characteristics that enable them to fit into the new environment. Example The great white skin's color makes it difficult for it to be seen in the dark.
Stage 3: Reproductive Isolation.
At this stage, organisms of the same species reunite and do not interbreed. Here, species are isolated into new ones so they have the best adaptations for their new habitat.

A block of mass 500 g is attached to a horizontal spring, whose force constant is 25. 0 n/m. The block is undergoing simple harmonic motion with an amplitude of 6. 00 cm. At t=0 the block is 4. 00 cm to the left of its equilibrium position and is moving to the right. At what time t1 will it first reach the limit of its motion to the right?
The time taken for the car to reach the limit or amplitude of the motion is 0.33 s.
Equation for the simple harmonic motion of the block
The equation for the simple harmonic motion of the block is calculated as follows;

400 students were randomly sampled from a large university, and 289 said they did not get enough sleep. Conduct a hypothesis test to check whether this represents a statistically significant difference from 50%, and use a significance level of 0. 1
Answer:
The sample proportion represents a statistically significant difference from 50%
Explanation:
The sample proportion is the same as 50%
Alternate hypothesis: The sample proportion is not the same as 50%
z = (p' - p) ÷ sqrt[p(1 - p) ÷ n]
p' is sample proportion = 289/400 = 0.7225
p is population proportion = 50% = 0.5
n is number of students sampled = 400
z = (0.7225 - 0.5) ÷ sqrt[0.5(1 - 0.5) ÷ 400] = 0.2225 ÷ 0.025 = 8.9
The test is a two-tailed test. Using a 0.01 significance level, critical value is 2.576. The region of no rejection of the null hypothesis is -2.576 and 2.576.
Imagine that 64% of the people living in a remote village in the mountains can taste phenylthiocarbamide (ptc). In order to taste ptc, you must have at least one copy of the dominant ptc taster allele. If the population were in hardy-weinberg equilibrium for the ptc gene, calculate the allele and genotype frequencies as listed below:
If the population were in Hardy-Weinberg equilibrium then the frequency of heterozygous will be 0.48, recessive homo-zygous 0.36 and dominant homo-zygous 0.16.
What is the Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium is a model used in population genetics to estimate genotypic and allele frequencies.
The Hardy-Weinberg equilibrium is p2 + 2pq + q2 = 1. In this case, p2 + 2pq is equal to 0.64.
In consequence, q2 = 1 – 0.64 = 0.36 >> q is equal to 0.6 and p = 1 – 0.6 = 0.4.
Finally, the frequency of heterozygous is 2pq (2 x 0.4 x 0.6) = 0.48, recessive homo-zygous is 0.36 and dominant homo-zygous is 0.16 (1 - 0.48 - 0.36 = 0.16).

In an electrochemical cell, electrons flow from anode to cathode while current flows in the opposite direction.
What is an electrochemical cell?The question is incomplete but it clearly relates to an electrochemical cell so I will answer in a general way. An electrochemical cell consists of a cathode and an anode. The anode is positively charged while the cathode is negatively charged.
We should note that electrons flow from anode to cathode but the flow of current is in the opposite direction. This occurs because the electron is negatively charged.

INCORRECT!!!!!!!
Explanation:
The sentence "no repites eso" is grammatically correct in Spanish, but it is not grammatically correct in English. The correct translation of "don't repeat that" in Spanish is "no repitas eso".
What is sentence?A sentence is a group of words that express a complete thought or idea. It is a fundamental unit of language that conveys meaning to the reader or listener.
A sentence typically consists of a subject, which is what the sentence is about, and a predicate, which describes what the subject is doing or what is happening to it.
A sentence can also contain other elements, such as an object or complement, that further describe or modify the subject or predicate. Sentences can vary in length and complexity, from simple one-word sentences to complex sentences with multiple clauses.
Effective sentence construction is important for clear communication, both in written and spoken language. Skilled writers and speakers use a variety of sentence structures to convey their message with precision and impact.

To crack a nut a force of magnitude (or greater) must be applied on both sides, as shown in the figure. One can see that a nutcracker only applies this force at the point in which it contacts the nut (at a distance from the nutcracker pivot). In this problem the nut is placed in a nutcracker and equal forces of magnitude are applied to each end, directed perpendicular to the handle, at a distance from the pivot.
