A particle travels along the x-axis with velocity v ( t ) = 2 t 1 + t 2 m/s for 0 ≤ t ≤ 3 seconds. If the particle’s position at t = 0 is x ( 0 ) = 5 , what is its position at t = 3? Show all of your work.
Its position at t = 3 is 7.3025850929
How to solvev(t)=(2t)/(1+t^2)
To find the position we need to integrate the function
p(t) = ∫ v(t)
p(t) =∫(2t)/(1+t^2) dt
Using u substitution
u = 1+t^2
du =2t dt
p(t) =∫(du)/(u)
We know that the integral of 1/u du is ln |u|
p(t) = ln|u| +C
Substituting back for u
p(t) = ln|1 +t^2| +C
To find the value of C, we let t=0
p(0) = ln|1 +0| +C = 5
= ln(1) +C =5
0 +C =5 Therefore C=5
p(t) = ln|1 +t^2| +5
We want to find the position at t=3
p(3) = ln|1 +3^2| +5
= ln(10) +5

Daisy Bryan is the purchasing managing for the bookstore in Morant Bay. Annual demand for a paperback dictionary at the bookstore is 1200 units. Ordering costs are $350 every time an order is made; carrying costs are 6% of the cost of each unit per year. The cost of a dictionary is $3,200. The lead time is 9 days. The bookstore is open for 300 days of the year. Advise Glenis on the optimal inventory policy to include the following: 1.The Economic Order Quantity 2. annual holding cost 3Annual Ordering cost 4.The reorder point 5.The Cycle Time 6.The Number of orders per year
The Economic Order Quantity (EOQ) is an inventory management technique used to determine the optimal order quantity. In this case, the EOQ is determined to be 99 units.
How to calculate the valueD = 1200 units
S = $350
H = 0.06 x $3,200 = $192
Plugging these values into the formula, we get:
EOQ = sqrt(2 x 1200 x $350 / $192) = 99.15
Therefore, the Economic Order Quantity is 99 units.
Annual holding cost = EOQ x H / 2 = 99 x $192 / 2 = $9,504
Annual ordering cost = D / EOQ x S = 1200 / 99 x $350 = $4,242.42
Reorder point = D x Lead time / Working days per year + Safety stock
Reorder point = 1200 x 9 / 300 + 120 = 156 units

Describe the change in the dominant economic sector during industrialization and during deindustrialization
During industrialization, there was a shift from an agrarian-based economy to a manufacturing-based economy.
What is the explanation for the above response?During industrialization, there was a shift from an agrarian-based economy to a manufacturing-based economy. This was driven by the development of new technologies and the growth of factories and industries that required large numbers of workers. The manufacturing sector became the dominant economic sector, as production of goods and services increased and cities grew around factories.
During deindustrialization, there was a shift away from the manufacturing sector towards the service sector. This was driven by factors such as globalization, automation, and changes in consumer preferences. Many manufacturing jobs were outsourced to other countries, and automation reduced the need for human labor. As a result, the service sector became the dominant economic sector, with growth in industries such as healthcare, education, and finance.
This shift led to changes in the nature of work and employment, with many workers moving from manufacturing jobs to service jobs.

AnswerAnswer:
while both Liszt and Chopin were virtuosic piano composers of the Romantic era, they had distinct differences in their style, compositional forms, and harmonic language. Liszt was known for his virtuosic and flamboyant piano style, innovative forms,
Explanation:
Franz Liszt and Frédéric Chopin were both renowned composers of the Romantic era, known for their virtuosic piano compositions. However, while they both contributed significantly to the piano repertoire, they had distinct differences in their compositional style, influences, and contributions to the music world.
Style and Technique:
Liszt was known for his flamboyant and virtuosic piano style, characterized by dazzling displays of technical prowess, intricate fingerings, and use of innovative piano techniques such as sweeping arpeggios, octaves, and fast scale passages. He often incorporated elements of showmanship in his performances, earning him the reputation of being one of the greatest piano virtuosos of his time. One of his most famous compositions, "La Campanella," showcases his virtuosity with its rapid-fire arpeggios and intricate fingerings.
On the other hand, Chopin's style was more delicate, poetic, and expressive. His compositions were known for their nuanced phrasing, rich harmonic language, and deep emotional expressiveness. Chopin's music often reflects his Polish heritage, with influences from Polish folk music, dance forms, and lyrical melodies. For example, his Nocturne in C-sharp minor, Op. 27, No. 1, is a beautiful example of his expressive and lyrical style, with its flowing melodies and rich harmonies.
Compositional Forms:
Liszt and Chopin also differed in their choice of compositional forms. Liszt's music spans a wide range of forms, from symphonic poems, piano concertos, and solo piano works, to choral and chamber music. He was known for his innovative approach to form, often blurring the lines between different musical genres and pushing the boundaries of traditional forms. For example, his symphonic poem "Les Préludes" is a groundbreaking work that combines elements of symphony and programmatic music, with its lush orchestrations and evocative storytelling.
In contrast, Chopin's compositions were primarily for solo piano and revolved around forms such as nocturnes, etudes, ballades, and polonaises. He is considered a master of these forms, elevating them to new heights of expressiveness and technical complexity. For instance, his Ballade No. 1 in G minor, Op. 23, is a prime example of his ability to create a narrative and emotional arc within a single piano work, with its dramatic shifts in mood, virtuosic passages, and lyrical melodies.
Harmonic Language and Influence:
While both Liszt and Chopin were known for their harmonic innovations, they had different approaches to harmony. Liszt's music often featured bold and daring harmonic progressions, pushing the boundaries of tonality and experimenting with chromaticism. He also explored unconventional tonal relationships and tonal ambiguity in his compositions, which was a departure from the traditional tonal language of his time. For example, his piano work "Un Sospiro" showcases his use of colorful harmonies and innovative tonal relationships.
Chopin, on the other hand, retained a more traditional tonal language but infused it with his own unique sense of chromaticism and harmonic sophistication. His harmonies were often characterized by rich chromatic chords, lush modulations, and colorful tonal progressions. His music had a profound influence on later composers, including Debussy and Ravel, who adopted his harmonic language in their own works.

Answer:
A. The observation of the cosmic microwave background led to the idea that the Universe started out in a big bang.
Explanation:
The cosmic microwave background (CMB) is radiation left over from the Big Bang. It is the oldest light in the Universe and provides a snapshot of the Universe at a very early time. The CMB was discovered in 1964 by Arno Penzias and Robert Wilson, and its existence supports the Big Bang theory. The CMB is nearly uniform in all directions, with small variations that correspond to the density fluctuations in the early Universe that gave rise to the formation of galaxies and other structures. The CMB is one of the strongest pieces of evidence for the Big Bang theory and led to its widespread acceptance among scientists.

It should be noted that f(x) is increasing on the interval (-∞, 1).
How to explain the function2e^-x - 2xe^-x > 0
2e^-x > 2xe^-x
Dividing both sides by 2e^-x (which is always positive), we get:
1 > x
Therefore, f(x) is increasing on the interval (-∞, 1).
Also f'(x) = 2e^-x - 2xe^-x
At x = 1, we have:
f'(1) = 2e^-1 - 2e^-1 = 0
Since f'(x) changes sign from negative to positive as we move from x = 1 to x < 1, we conclude that f(x) has a relative minimum at x = 1.
