it is known that a certain kind of algae in the dead sea can double in population every 3 days. suppose that the population of algae grows exponentially, beginning now with a population of 1,000,000.
An algal bloom, also known as eutrophication, is the fast growth of algae populations in freshwater or marine water systems as a result of an overabundance of nutrients, notably phosphorus and nitrogen.
What are the causes of Cyanobacteria?Examples of toxic algal blooms that can have detrimental effects on people's health, aquatic ecosystems, and the economy include red tides, blue-green algae, and cyanobacteria.
A cyanobacteria bloom can be caused by two factors: an abundance of nutrients, and warm water temperatures.
The main sources of extra nutrients that might cause a bloom in a water body are septic tank overflows, lawn and agricultural fertilizers, and fertilizers used on crops.
Therefore, Algal blooms might be poisonous. Pets and people should stay away from any green, slimy, or odorous water.

a small amount of sodium hydroxide is added to water. when the chemical reaction reaches equilibrium, the ph is 12. which statement and conclusion about sodium hydroxide is correct?
The correct statement and conclusion about sodium hydroxide (NaOH) is: The negative log of the concentration of [tex]OH^-[/tex] ions is 12, so Sodium hydroxide is a strong base.
In Chemistry, pH literally means the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions in a particular solution, thereby, specifying the following;
The acidity of a chemical solution.The neutrality of a chemical solution.The basicity (alkanility) of a chemical solution.On a related note, a pH scale is a scale that is used to measure the concentration of hydrogen ions in both acidic and basic (alkaline) solutions.
Generally, a pH scale is calibrated with a standard measurement that ranges from 0 to 14.
On a pH scale, a solution with a pH of 7 is neutral, a solution with a pH below 7 is acidic and a solution is considered to be basic (alkaline) when its pH is above 7.
In this experiment, a small amount of sodium hydroxide is added to water, to give a pH of 12 when the chemical reaction reaches equilibrium.
Hence, the negative log of the concentration of [tex]OH^-[/tex] ions is 12, so Sodium hydroxide is a strong base.

How do the passages' themes compare? Both passages have the theme "time erases everything." "Elgin Marbles" has the theme "art outlasts even death," while "Ozymandias" has the theme "death comes to everything." Both passages have the theme "nature is cruel." "Elgin Marbles" has the theme "decay is inevitable," while "Ozymandias" has the theme "fame survives death."
The two passages have the theme "time erases everything," as shown in the first answer option.
We can arrive at this answer because:
The passage from the poem "Ozymandias," shows how all the glory, wealth, and magnificence of a great leader fades over time.In this poem, we can see that someone seen as the king of kings, can have all his power terminated and buried in the sand.In "On Seeing the Elgin Marbles," we can see how memorable moments pass and become memories of "the old days," even though it seems like it will last forever.In this case, we can see that the two poems reinforce the idea that everything is fleeting, and that time brings the end of all things.

The full passage is below
(1) For centuries, art scholars have studied the renowned works of Leonardo da Vinci, the Renaissance artist, pondering how he created three-dimensional figures with such depth on flat canvases. (2) If da Vinci did have exotropia, in which an eye turns outward, he would not have been the only artist in history with that condition.
(3) Christopher Tyler, a visual neuroscientist at City University of London, noticed a pattern in da Vinci’s portraits and in works depicting the great artist. (4) While few self-portraits of da Vinci exist, Tyler argues that many of da Vinci’s portraits reflect his appearance. (5) As the great artist himself said, the soul “guides the painter’s arm and makes him reproduce himself, since it appears to the soul that this is the best way to represent a human being.”
(6) To test his theory that da Vinci had exotropia, Tyler studied the eye alignments of the subjects of six pieces of art that purportedly depict the Renaissance artist himself, including da Vinci’s Vitruvian Man and Salvator Mundi and Andrea del Verrocchio’s sculpture David. (7) The results confirmed Tyler’s suspicions: da Vinci likely had exotropia, with one eye turning out at -10.3 degrees.
(8) Tyler’s findings, which he published in JAMA Ophthalmology, created a stir in both the art and science communities. (9) Only about 1 percent of the population has exotropia, yet previous studies have suggested that other famous artists—like Rembrandt, Picasso, and Degas—had it as well, which indicates that the eye condition was more common in centuries past than it is now. (10) Tyler believes that da Vinci’s condition was intermittent—that is, his eye drifted out of alignment when he was relaxed, but when he focused, it would realign. (11) If Tyler is right and da Vinci could control his exotropia, then the artist could switch from 2-D to 3-D vision, enhancing his ability to accurately capture three-dimensional figures on a two-dimensional canvas.
The writer is working on a revision of the passage and has written the following thesis statement for it.
Based on the evidence from Tyler’s studies, it is clear that this condition was the primary reason for da Vinci’s success.
Which of the following is most likely the main claim that the writer is planning to make in the new version of the passage?
A The only way for an artist to be successful is to have exotropia.
B. Da Vinci was more successful as an artist than others who also had exotropia.
C. Studying just a few works of art can provide compelling information about an artist’s physical conditions.
D. The only way to fully understand an artist’s work is to study the artist’s physical conditions.
E. Da Vinci was a great artist because he had exotropia

identifies x as the smaller number?
Answer:
x + y = 6
3x + 2y = 32
Multiply the ist equation by 3: 3x + 3y = 18 Subtract one equation from the other: y = - 14, then x = 6 - y = 20 Now take the values of x and y and make sure they solve the problem.
if not then its this

jose had a beautiful plant. it began sprouting 2 days before alexa bought it, and he took care of it for 88 days before it died. at its tallest, the plant was 20 cm tall. let h(t) denote the height of jose’s plant (measured in cm), t days from the time he bought it. which set of numbers is more appropriate for the domain of the function?
The domain of a function is the set of values which the function can take as input and be defined. In this scenario, these are the values of time, t. Hence, the set of numbers which is appropriate for the domain is - 2 ≤ t ≤ 88 (real numbers).
The height of the plant is a function of time, h(t) ;
Sprouting time before purchase, t = - 2 days Number of days after purchase before death = 88 (endpoint)Hence, the domain of the function is the set of values in the inequality ;
- 2 ≤ t ≤ 88Therefore, the domain is the set of real numbers between - 2 ≤ t ≤ 88
