Answer:

independent variable: water given to the plants

Dependent variable: height of each plant

Explanation:

The independent and the dependent variables are the two principal factors needed in an experiment.

• Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The independent variable changes or is controlled and modified in the experiment to analyze how the other variable responds to it. The researcher can change it to see what changes it implies in an object, process, trait, or anything that depends on them, to study its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the researcher manipulates the water given to the plants.  One plant receives water that has been microwaved and the other plant receives regular tap water.

• Responding variable: Refers to the dependant variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. A change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y.  In the exposed example, the dependent variable is the height of each plant after 2 weeks of treatment.

• Controlled variable: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example these are the light and pots.

Area of a Circle Formula:
\(\displaystyle A = \pi r^2\)

Differentiation

Derivative Property [Multiplied Constant]:
\(\displaystyle (cu)' = cu'\)

Derivative Rule [Basic Power Rule]:

Derivative Rule [Chain Rule]:
\(\displaystyle [u(v)]' = u'(v)v'\)

Let's organize what the problem gives us.

We are told that the area of a circle is decreasing at 122 in²/min.

⇒  \(\displaystyle \frac{dA}{dt} = -122 \frac{\text{in}^2}{\text{min}}\)

We are also told an instantaneous point: the area of the circle is 16π in².

We are asked to find the rate of change of the radius.

Let's first differentiate our area of a circle formula with respect to time. Apply basic differentiation rules listed above under "Calculus":

\(\displaystyle\begin{aligned}\frac{d}{dt}[A] & = \frac{d}{dt}[\pi r^2] \\\frac{dA}{dt} & = \pi \frac{d}{dt}[r^2] \\\frac{dA}{dt} & = 2 \pi r \frac{dr}{dt} \\\end{aligned}\)

∴ we have found the relationship between the change in area and the change in radius w/ respect to time.

Now we need to determine what the radius is when the area of the circle is equal to 16π in²:

\(\displaystyle\begin{aligned}16 \pi \ \text{in}^2 & = \pi r^2 \\r^2 & = 16 \ \text{in}^2 \\r & = \boxed{ \pm 4 \ \text{in} } \\\end{aligned}\)

∴ the radius of the circle when the area is equal to 4 in, since the radius of the circle can't be negative.

With all of our variables, we can now substitute them into our derivative and solve for the rate of change of the radius:

\(\displaystyle \frac{dA}{dt} = 2 \pi r \frac{dr}{dt} \Rightarrow -122 = 2 \pi (4) \frac{dr}{dt}\)

\(\displaystyle\begin{aligned}\frac{-122 \frac{\text{in}^2}{\text{min}}}{2 \pi (4 \text{in})} & = \frac{dr}{dt} \\\frac{dr}{dt} & = \frac{-122 \frac{\text{in}^2}{\text{min}}}{8 \pi \ \text{in}} \\& = -4.8542257643 \frac{\text{in}}{\text{min}} \\& \approx \boxed{ -4.854 \frac{\text{in}}{\text{min}} } \\\end{aligned}\)

∴ the rate of change of the radius is equal to -4.854 inches per minute rounded to the thousandths place. Reworded, the rate of change of the radius decreases by 4.854 inches per minute.

∴ at the instant when the area of the circle is 16π square inches, the change of the radius is equal to:
\(\displaystyle \boxed{ \frac{dr}{dt} \approx -4.854 \frac{\text{in}}{\text{min}} }\)

Mother-daughter relationships are an important theme in plays as they allow playwrights to explore complex emotions and themes. For playwrights with daughters, the mother-daughter play can be a way to come to terms with the mixed emotions that accompany the transition from daughterhood to motherhood. For those writers committed to celebrating matrilineage, the mother-daughter play can lead to mutual liberation and the renewal of bonds based on equality.

In an essay on the importance of mother-daughter relationships in a play, one could argue that these relationships provide a rich source of emotional depth and complexity. They allow playwrights to explore themes such as love, loss, identity, and generational conflict. By portraying the struggles and triumphs of mothers and daughters, plays can shed light on the human condition and help us better understand ourselves and our relationships with others.

Children's emotional bonds with their parents have significant implications for their social, emotional, and cognitive development. Research has shown that strong emotional bonds with parents help children to feel secure and develop a sense of trust in their environment. Children who have positive relationships with their parents tend to be more confident, empathetic, and better able to regulate their emotions. Additionally, these emotional bonds can serve as a buffer during times of stress or adversity, helping children to cope more effectively. On the other hand, children who have insecure attachments to their parents may struggle with emotional regulation, have difficulty forming healthy relationships, and experience a range of negative outcomes later in life. Therefore, the quality of the emotional bonds children have with their parents is a critical factor in their overall development and well-being.

Integration

Integration Rule [Fundamental Theorem of Calculus 2]:
\(\displaystyle \frac{d}{dx}[\int\limits^x_a {f(t)} \, dt] = f(x)\)

Let's organize what is given to us from the problem.

We are given an initial condition: f(0) = 5.420

We are given a derivative:
\(\displaystyle f'(x) = \sqrt{\sin^2 x + x}\)

We are asked to find f(2π).

We can first formulate a rough function using integration rules, namely the Fundamental Theorem of Calculus (2nd part):

\(\displaystyle f(x) = \int \limits^{x}_{a} f(t) \, dt + C_0\)

where f(t) is a derivative function and C₀ is an initial condition.

Now that we have a "baseline formula", we can substitute in our f(t) derivative function, our limits, and our initial condition:

\(\displaystyle f'(x) = \sqrt{\sin^2 x + x} \Rightarrow f(t) = \sqrt{\sin^2 t + t}\)

\(\displaystyle \begin{aligned}f(x) & = \int \limits^{x}_{a} f(t) \, dt + C_0 \\& = \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + f(0) \\& = \boxed{ \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 } \\\end{aligned}\)

∴ our general function is equal to:
\(\displaystyle \boxed{ f(x) = \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 }\)

*Note:

There isn't an antiderivative for the general function, so you will have to input the integral into a calculator.

In order to find the value of f at 2π, we substitute x = 2π into our general function:

\(\displaystyle \begin{aligned}f(2 \pi) & = \int \limits^{2 \pi}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 \\& = 11.44863485704886 + 5.420 \\& = 16.868634857 \\& \approx \boxed{ 16.868 } \\\end{aligned}\)

∴  \(\displaystyle \boxed{ f(2 \pi) \approx 16.868 }\)

∴ the value of f(2π) is approximately 16.868.

Japanese Knotweed: This plant species, native to Japan, was introduced to the United Kingdom in the mid-19th century and has since become one of the most problematic invasive species in the country. It can grow up to 10 cm per day, and its roots can damage buildings, roads, and other structures.

Zebra Mussel: This freshwater mussel, native to Eastern Europe, was accidentally introduced to the Great Lakes in the 1980s through ballast water from ships. Since then, it has spread rapidly and significantly impacted the ecosystem, out-competing native species and causing damage to water intake pipes and other infrastructure.

Burmese Python: These large snakes, native to Southeast Asia, were introduced to Florida in the 1990s as a result of the pet trade. They have since become established in the state and have significantly impacted native wildlife populations.

Cane Toad: Native to South and Central America, the cane toad was introduced to Australia in the 1930s in an attempt to control sugar cane beetles. However, the toads have since become a major problem, with their toxic skin secretions killing native predators and their voracious appetites causing damage to native insect populations.
