A graph that correctly represents the relationship between arc length and the measure of the corresponding central angle on a circle with radius r is: C. graph C.

In Mathematics and Geometry, if you want to calculate the length of an arc formed by a circle, you will divide the central angle that is subtended by the arc by 360 degrees and then multiply this fraction by the circumference of the circle.

Mathematically, the length of an arc formed by a circle can be calculated by using the following equation (formula):

Arc length = 2πr × θ/360

In this context, we can reasonably infer and logically deduce that the arc length is directly proportional to the radian measure of the central angle.

Answer: The given expression, 2430 + 15√2, cannot be simplified further as it is already in its simplest form. However, you can approximate its value using a calculator or by using a decimal approximation of the square root of 2.

Using a calculator, you can directly evaluate the expression to get:

2430 + 15√2 ≈ 2462.11

Alternatively, you can use a decimal approximation of the square root of 2, which is approximately 1.414:

2430 + 15√2 = 2430 + 15 * 1.414 ≈ 2430 + 21.21 = 2451.21

Therefore, 2430 + 15√2 is approximately equal to 2462.11 or 2451.21, depending on the method used for approximation.

Step-by-step explanation:

In 1973, the batting average of .350 of Rod Carew is more impressive as it has a higher z-score of 2.81

To establish which batting average was more spectacular, we must compare it to the mean and standard deviation of 1970s hitting averages. The case of Jackie Robinson,

z = (x - μ) / σ

z = (.342 - .261) / .0317

z = 2.56

For Rod Carew,

z = (x - μ) / σ

z = (.350 - .261) / .0317

z = 2.81

A higher z-score indicates a more impressive performance relative to the mean. As a result, Rod Carew's .350 batting average was more spectacular, as it had a higher z-score of 2.81 than Jackie Robinson's z-score of 2.56.

For the given question the values,

Given value of the function when the condition for x is less than '0' is =

f(x) = x²   for x < 0

The value of the function when the condition x is equals to '0' is =

f(x) = 0     for x = 0

The value of the function when the condition x is greater than '0' is =

f(x) = 3x + 4    for x > 0

From the above information,

To find f(-1) we have to use the x value as x². So, f(-1) = (-1)² = 1

To find f(0) we have to use x value as 0. So, f(0) = 0

To find f(3) we have to use the x value as 3x + 4. So, f(3) = 3(3) + 4 = 13.

From the above analysis, we find the values of f(-1), f(0), and f(3).

Deviance is a term used in sociology to describe behavior that violates social norms or expectations. It refers to any behavior that is considered outside of the established rules and expectations of a society or culture.

Informal negative sanctions are the social disapproval or punishment that people receive for violating social norms. An example of informal negative sanctions could be a group of friends ostracizing another friend for breaking a social rule, such as not showing up to a planned event.

In terms of the act of deviance, it could be anything from breaking a minor social norm to committing a serious crime. The reaction of informal negative sanctions is often an attempt to maintain social control by encouraging conformity to the established norms of the group or society.

While physical violence is not necessary to maintain social control, the threat of punishment is an important part of any functioning society. People follow the rules and norms of society because they know that if they do not, there will be consequences. However, it is important to note that violence and punishment should not be the only means of social control. Positive reinforcement, such as rewards for good behavior, can also be an effective way of encouraging conformity to social norms.

In summary, deviance refers to behavior that violates social norms, and informal negative sanctions are a way of enforcing social norms. The threat of physical violence is not necessary to maintain social control, but consequences for deviant behavior are essential for any functioning society.

Answer:

366,699

Step-by-step explanation:

to solve this problem, we can use the following formula for exponential growth:

population = initial population x (1 + growth rate)^time

where the initial population is the current population, the growth rate is the rate of increase per year, and the time is the number of years.

Plugging in the given values, we get:

population = 300,000 x (1 + 0.02)^10

Simplifying, we get:

population = 300,000 x 1.02^10

Using a calculator, we get:

population ≈ 366,698.79

Rounding to the nearest whole number, we get:

population ≈ 366,699

The population in 10 years will be approximately 366,699

[tex]\large{\boxed{a^2+b^2=c^2}[/tex]

where:

From inspection of the given diagram:

Substitute these values into the formula and solve for x.

Substitute the found value of x into the expression for each side length.

Answer: Therefore, the population will exceed 100,000 in the year 2005 + 10.73 ≈ 2016.

Step-by-step explanation:   a) The population of the town in 2005 is given by the formula, where t = 0 since 2005 is the starting year:

P = 50,000(1.15)^0 = 50,000

Therefore, the population of the town in 2005 was 50,000.

b) We need to find the value of t when the population P exceeds 100,000:

100,000 = 50,000(1.15)^t

Divide both sides by 50,000:

2 = 1.15^t

Take the natural logarithm of both sides:

ln 2 = ln (1.15^t)

Apply the power rule of logarithms:

ln 2 = t ln 1.15

Divide both sides by ln 1.15:

t = ln 2 / ln 1.15

Using a calculator, we get:

t ≈ 10.73
