In gradient descent, we take the negative gradient, which is formed by the partial derivatives, to determine the steepest descent direction. It allows us to iteratively approach the minimum of the function.
In gradient descent, the goal is to minimize a function by iteratively adjusting the parameters or variables. While it may seem intuitive to take the maximum of the partial derivatives to determine the steepest descent direction, it is not the correct approach.
In gradient descent, we actually take the negative of the gradient, which is the vector formed by the partial derivatives of the function with respect to each variable. The negative gradient points in the direction of steepest descent. By moving in the opposite direction of the gradient, we can iteratively approach the minimum of the function.
Mathematically, for a function \(f(x1, x2, ..., xn)\), the gradient is represented as \(∇f = (∂f/∂x1, ∂f/∂x2, ..., ∂f/∂xn)\). The negative gradient is then \(-∇f = (-∂f/∂x1, -∂f/∂x2, ..., -∂f/∂xn).\)
Taking the negative gradient ensures that we move in the direction of decreasing function values. By adjusting the parameters in the negative gradient direction and updating them iteratively, we approach the minimum of the function.
In conclusion, in gradient descent, we take the negative gradient, not the maximum of the partial derivatives, to determine the steepest descent direction and minimize the function.

What causes the frequent migration of animals in Africa?
O A. European colonization
B. Changes to natural resources
O C. Global climate changes
O D. Civil war
Answer: B. changes to natural resources!
Explanation: I hope this helps
Animals usually migrate to find food and water. In Africa, due to the dramatic changes in weather, animals migrate frequently. In many cases, they have to travel long distances in order to maintain their access to adequate water and food, often following the rains. Recently, scientists found that some zebras migrate over 300 miles one way to find food and water - this is the longest documented migration of large mammals in Africa.
Answer:
water sources changing
Explanation:
i got the answer wrong on myne
Which statement is most likely a scientific law? Animals need oxygen because it unlocks the energy contained in food. Colonies of microscopic organisms grow faster in closed spaces because they cannot fly away. The oldest layers of rock lie below newer layers of rock on Earth. Healthy foods taste better than dangerous or spoiled foods.
Answer:
The oldest layers of rock lie below newer layers of rock on Earth.
Explanation:
Scientific law can be defined as a description of natural phenomenon. The scientific law does not explain the 'why' of occurence of natural phenomenon instead it describes it.
From the given options, the correct statement is that oldest layers of rock lies below the newer layers. It is a scientific law that oldest layer of rocks is covered up with newer layer of rocks. It is a natural phenomenon that occurs in the nature of earth formation.
Thus the correct answer is the third option.

What place in the original solar nebula was cold enough for ice to form?
Answer:
the frost line
Explanation:
Ice formed in the outer regions of the original solar nebula, where temperatures were cold enough for water vapor and other volatile substances to condense into solid ice.
This region, known as the "snow line," is thought to have been located at about 3-4 astronomical units (AU) from the sun, where temperatures were low enough for water ice to persist. Beyond the snow line, water and other volatile compounds were abundant and could contribute to the formation of large, icy objects such as comets and Kuiper Belt objects.
In the inner regions of the nebula, where temperatures were too high for ice to form, volatile compounds were mostly evaporated, leading to the formation of rocky and metal-rich objects like the inner planets.
The snow line played a key role in the formation and evolution of the solar system, as it divided the nebula into two distinct regions with different chemical compositions and helped to determine the types of objects that could form in each region.
This division helped to shape the early architecture of the solar system, including the formation of the gas giants and the distribution of planetary masses and orbits.

the term urban sprawl describes the expansion of cities into rural areas. this phenomen has ccured around the world and has had economic, health, and environmental consequences
Yes, the term "urban sprawl" generally refers to the outward expansion of cities into previously rural or undeveloped areas, often resulting in low-density, automobile-dependent development patterns.
Urban sprawl has occurred in many regions around the world and has had a range of economic, health, and environmental consequences.
(a) Two causes of urban sprawl are population growth and the desire for larger living spaces. As populations increase, cities expand to accommodate more people, and as people become more affluent, they often seek larger homes with more land, which can only be found outside of cities in rural areas.
(b) Two human health effects associated with urban sprawl are increased air pollution and decreased physical activity. As more people move into suburban areas, there is an increase in traffic and emissions from cars, which can contribute to respiratory problems and other health issues.
Additionally, suburban areas often lack sidewalks and public transportation, making it difficult for residents to engage in physical activity and maintain a healthy lifestyle.

The monthly payment is
Answer:
235
Explanation:
The monthly payment for the student loan which is calculated at annual interest rate is approximately $103.64.
What is annual interest rate?
The portion of the principal (the initial sum of money borrowed or invested) that is charged or earned as interest over the course of a year is known as the annual interest rate.
The total interest paid or gained over the course of a year can be calculated using the annual interest rate, which is frequently used to compare various financial products like loans and savings accounts. The annual interest rate must first be changed to a monthly rate. By dividing the annual rate by 12, we can do this:
i = 2.5% / 12 = 0.021
The loan period must therefore be changed from years to months:
t = 15 years times 12 months per year, or 180 months.
The values can now be entered into the formula as follows:
\(M = (15000 * 0.021) / (1 - (1 + 0.021)^-^1^8^0)\)
Using a calculator, we get:
M ≈ $103.64
Therefore, the monthly payment for the student loan is approximately $103.64.

A sea breeze usually originates during the day and flows toward the land.
What are Sea Breezes?Sea breezes are winds that blow from the sea to the land, and they happen because of the difference in temperature between the land and sea. During the day, the sun heats up the land faster than the sea, causing the air above the land to warm up and rise. As a result, the air pressure over the land becomes lower than over the sea.
Meanwhile, the sea remains cooler than the land, which causes the air above it to be denser and create an area of higher pressure. This difference in pressure creates a breeze that blows from the sea towards the land, and it is called a sea breeze.

transhumance is a type of pastoralism or nomadism, the seasonal movement of livestock between fixed summer and winter pastures. In mountainous regions (vertical migration), this means migrating between high meadows in summer and low-lying valleys in winter. Shepherds usually have a permanent home in the valley. In general, only herds move with the specific number of people needed to support them, with the main population staying on base. more susceptible to disruption by change.
Traditional or fixed herding occurs throughout the inhabited world, especially in Europe and Western Asia. Dairy products (milk, butter, yoghurt, cheese) of migrating herds are often important to pastoral societies, as they can make up a large part of the diet of such groups.
