What is urbanization?

Urbanization is the process by which an increasing proportion of the population in a country or region moves from rural areas to cities or urban areas. This is usually accompanied by a growth in the size and number of cities and towns, as well as changes in the way people live and work.

The correct answer is "growth of cities." Urbanization refers to the process by which more and more people live in cities or urban areas, rather than in rural areas. During the Song period in China (960-1279 AD), there was significant economic growth, which led to increased trade, technological advancements in farming, and the widespread use of money. As a result, more people were able to move to cities, which grew in size and complexity. Urbanization was an important aspect of the economic, social, and cultural changes that occurred during the Song period, and it helped to shape the development of Chinese society in subsequent centuries.

Answer:

55°

Step-by-step explanation:

For the line including the 110°, the angle of the supplementary angle is 70° which is the 'non-equivalent' length of the isosceles triangle. Then do:

(180°-70°)/2 = 55° to get x

Answer:

Supplementary angles, x = 55

Step-by-step explanation:

Supplementary angles: straight line means both angles add up to 180, this if the outside angle is 110 then the inside angle is 180° - 110° = 70°

Since it is an isosceles triangle, it means both angles are equal to x therefore

\(180 - 70 = 2x\\110 = 2x\\\frac{110}{2} = x\\x = 55\)

Answer:

If x/15 = 1/3, we can solve for x by multiplying both sides of the equation by 15:

x/15 = 1/3

x = 15 * (1/3)

x = 5

Therefore, the value of x is 5.

Given that `x/15 = 1/3`. We need to find the value of `x`.To find the value of `x`, we need to cross multiply both sides of the equation.`x/15 = 1/3`=> `3x = 15`=> `x = 15/3`=> `x = 5`Hence, the value of `x` is `5`.

Answer:

both of these.will be solved by angle sum property which states that sum of all interior angles is 180 degrees

in a

one angle is 30 degrees

other is right angle means 90 degrees

total sum of these angles is 120

total sum of all angle must be 180 degrees

so the third angle is 60 degrees

in b

one angle is 45 degrees

other is a right angle means 90 degrees

total sum of these angles is 135

total sum of all angles must be 180 degrees

so the third angle is 45 degrees

Step-by-step explanation:

An exponential function to model the quail population is y = 765(1+0.16)ⁿ and the approximate population be after 4 years is 1384.65 quails.

Population growth is seen to increase at an exponential rate. We use the following to model this growth.

y = A₀(1 + r)ⁿ

where

y = value at time

A₀ = original value

r = rate of growth

n = time elapsed

An exponential function that models the quail population is set up like:

y = 765(1+0.16)ⁿ

so that, for example, if we wanted to figure out the population at time (4 years), then we would set up the function as follows,

y = 765(1+0.16)⁴

y = 765(1.16)⁴

y = 765* 1.81

to get

y = 1384.65 quails after 4 year has elapsed.

Hence, an exponential function to model the quail population is y = 765(1+0.16)ⁿ and the approximate population be after 4 years is 1384.65 quails.

Our function is a parabola, therefore, it has only one critical point which is its vertex. Since the coefficient of the squared term is negative, the vertex is the maximum point.The critical points of a function are given by the zeros of the first derivative. The first derivative of our function is:

The solutions for the following equation are the critical points of the original function:

The maximum point happens at x = - 3.

To find the corresponding value, we just have to evaluate x = - 3 into our function:

The maximum value of the function is 1, and it occurs at x = - 3.

Answer: The function has a maximum value

               The function's maximum value is 1

               The function's maximum value occurs at x=-3

Step-by-step explanation:

Given equation: \(g(x) = -3x^ - 18x - 26\)

We shall use the differentiation method to find the answer.

Differentiating the equation, we get   \(g'(x) = - 6x - 18\)

equating g'(x) = 0,

\(-6x - 18 = 0\\-6x = 18 \\x = -3\)

Hence the minimum/ maximum value of the function lies in x = -3

on equating x>-3, g'(x) is negative

on equating x<-3, g'(x) is positive

this proves that first, the function was increasing and after x = -3, the function started to decrease hence at x=-3, the function g(x) was at its maximum value

The function's maximum value at x=-3 is

\(g(x) = -3x^2 - 18x - 26\\g(-3) = -3(-3)^2 - 18(-3) - 26\\g(-3) = -3(9) +54 -26\\g(-3) = 54 - 27 -26\\g(-3) = 1\)

For the person to reach a retirement savings goal (future value) of $100,000 at age 55, they need to invest an additional $81 monthly.

The additional monthly investment is computed as the difference between the expected monthly deposits and the intended monthly deposits.

The expected monthly deposits (periodic payments) are determined using an online finance calculator.

Current age = 21 years old

Retirement age = 55 years old

Investment period = 34 years (55 - 21)

N (# of periods) = 408 months (34 years x 12)

I/Y (Interest per year) = 2.5%

Present Value = $0

FV (Future Value) = $100,000

Results:

Periodic Payments (PMT) = $155.75

Sum of all periodic payments = $63,546

Total Interest =  $36,454

Intended monthly deposits = $75

Additional monthly deposits required = $80.75 ($155.75 - $75) = $81

Thus, the investor needs to invest an additional $81 to the $75 monthly deposits to reach a future value of $100,000 in 34 years, compounded at 2.5% monthly.

To match decimal values with their corresponding hexadecimal values, we need to convert the decimal numbers into their hexadecimal equivalents using division and remainders.

To match each decimal value on the left with the corresponding hexadecimal value, we need to convert the decimal numbers into their hexadecimal equivalents.

Here are a few examples:

1. Decimal 10 = Hexadecimal A

To convert 10 to hexadecimal, we divide it by 16. The remainder is A, which represents 10 in hexadecimal.

2. Decimal 25 = Hexadecimal 19

To convert 25 to hexadecimal, we divide it by 16. The remainder is 9, which represents 9 in hexadecimal. The quotient is 1, which represents 1 in hexadecimal. Therefore, 25 in decimal is 19 in hexadecimal.

3. Decimal 128 = Hexadecimal 80

To convert 128 to hexadecimal, we divide it by 16. The remainder is 0, which represents 0 in hexadecimal. The quotient is 8, which represents 8 in hexadecimal. Therefore, 128 in decimal is 80 in hexadecimal.

Remember, the hexadecimal system uses base 16, so the digits range from 0 to 9, and then from A to F. When the decimal value is larger than 9, we use letters to represent the values from 10 to 15.In conclusion, to match decimal values with their corresponding hexadecimal values, we need to convert the decimal numbers into their hexadecimal equivalents using division and remainders.

Answer:

The slope is  \(s =\) $0.1774 / pounds

Step-by-step explanation:

From the question we are told that

   The weight of the rat is \(w_1 = 3.5 \ pound\)

     The cost of feeding the rat per week is \(c_1 =\)$4.50

     The weight of a Beagle is  \(w_2 = 30 \ pound\)

     The cost of feed a Beagle per week is  \(c_2 =\)$9.20

Now the slope can be evaluated mathematically as

           \(s = \frac{c_2 -c_1 }{w_2 -w_1 }\)

3y = 90-27

3y =63

y = 63/3

y = 21

Answer:

y = 21

Step-by-step explanation:

According to the Side Splitter Theorem, if a line parallel to one side of a triangle intersects the other two sides, then this line divides those two sides proportionally.

Therefore, according to the Side Splitter Theorem:

From inspection of the given triangle, the lengths of the line segments are:

To find the value of y, substitute the given line segment lengths into the proportion and solve for y:

\(\begin{aligned}\sf AD : DB &=\sf AH : HC\\\\3:7&=9:y\\\\\dfrac{3}{7}&=\dfrac{9}{y}\\\\3 \cdot y&=9 \cdot 7\\\\3y&=63\\\\\dfrac{3y}{3}&=\dfrac{63}{3}\\\\y&=21\end{aligned}\)

The solution to the inequality 2.4/n < 6 is n > 0.4, and the only value from the given options that satisfies this inequality is 0.5.

What is inequality ?

An inequality is a mathematical statement that compares two values or expressions using inequality symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).

Inequalities express a relationship between two quantities, indicating whether one quantity is less than, greater than, or equal to the other quantity.

We can solve the given inequality as follows:

2.4/n < 6

Multiplying both sides by n (note that n cannot be negative):

2.4 < 6n

Dividing both sides by 6:

0.4 < n

So, any value of n that is greater than 0.4 will be a solution to the inequality.

Out of the given options, only 0.5 is greater than 0.4, so 0.5 is the solution to the inequality.

Therefore, the solution to the inequality 2.4/n < 6 is n > 0.4, and the only value from the given options that satisfies this inequality is 0.5.
