length of the arc of the circle formed by this central angle is 12.56 units.

The formula for calculating arc length is used to determine the length of the arc's curved line (a segment of a circle). The arc length is, to put it simply, the distance that passes across the curved line of the circle that forms the arc. Arc stability, weld current, and part concentricity are all factors that affect arc length. Arc stability, weld current, and part concentricity are all factors that affect arc length. The commercial welder's job in this situation is to maintain the electrode at a specific distance from the surface so that there is adequate room to prevent stubbing out.

Since, the length of an arc on a circle is:

l = r × θ

Where, r is the radius of the circle and  is the central angle ( in radian ) made by the arc,

Here,

r = 8 unit,

θ = 90° = 90 × (π/180) = π/2

( π radian = 180°)

Hence, the length of the given arc is,

l = 8 × (π/2)

l = 4π

l = 12.56 units

The concept of instantaneous rate of change, also known as derivative, gives us the rate at which a quantity changes with respect to time at a specific instant. To find the instantaneous rate of change, we can take the derivative of the function that describes the position of the ball.

In this case, the position of the ball is given by the function f(x) = 2Vx, where V is the initial velocity of the ball. Taking the derivative of the function, we get the derivative as f'(x) = 2V, which represents the instantaneous rate of change of the ball's position with respect to time at any instant x.

When x = 9 seconds, the instantaneous rate of change of the ball's position is given by f'(9) = 2V. Therefore, the correct answer is d. 2/3V ft/sec.

The set of ordered pairs of A and C represents a linear function.

The graph of a linear function is a straight line. The following is the form of a linear function.

a + bx = y = f(x).

One independent variable and one dependent variable make up a linear function. x and y are the independent and dependent variables, respectively.

Given ordered pairs:

A (-2,8) (0,4) (2,3) (4,2)

B (1,2) (1,3) (1,4) (1,5)

C (-2,7) (0,12) (2,17) (4,22)

D (3,5) (4,7) (3,9) (5,11)​

The definition of a linear function is the relationship between input and output values.

Range refers to the set of output values, and domain refers to the set of input values.

The fact that an input value cannot have two different output values is the most significant attribute of functions (which defines them). Having stated so, observe how sets B and D include pairings that defy this rule.

Therefore, since each input value only produces one output value, the correct solutions are A and C.

Answer:

To calculate the length of the metal band, you need to first calculate the circumference of each pipe. The circumference of a pipe is equal to the diameter of the pipe multiplied by π (3.14). Therefore, the circumference of each pipe is 10 cm x 3.14 = 31.4 cm. Since there are 16 pipes, the total circumference of all the pipes is 16 x 31.4 cm = 500.64 cm. The length of the metal band will be the same as the total circumference, so it will be 500.64 cm.

The initial value problem for the concentration of salt in the tank over time will be: dc/dt = [(1 g/L * 2 L/min) - (c * 2 L/min)] / 2000 L

An initial value problem (IVP) in multivariable calculus is an ordinary differential equation with an initial condition that determines the value of the unknown function at a specific location in the domain. In physics or other sciences, modelling a system typically entails addressing an initial value issue.

Let's call the concentration of salt in the tank "c" (in grams/liter).

The initial concentration of salt in the tank is: c(0) = 400 / 2000 = 0.2 g/L

The rate of change of concentration with time "t" (in minutes) can be represented as:

dc/dt = (inflow rate of saltwater - outflow rate of saltwater) / volume of tank

dc/dt = [(1 g/L * 2 L/min) - (c * 2 L/min)] / 2000 L

This is the initial value problem for the concentration of salt in the tank over time.

The correct answer is d. 1/x².

The integrating factor for the given equation is 1/x².

To solve a linear differential equation, we must first find an integrating factor so that the equation can be integrated. The integrating factor for the given equation is 1/x². To calculate it, we must multiply both sides of the equation by the integrating factor.

Let's start by rearranging the equation: y' - y/x = x

We multiply both sides of the equation by the integrating factor, 1/x²:

(1/x²) (y' - y/x) = (1/x²) x

We can simplify the left side of the equation by factoring out the y': y'/x² + (y/x³) = (1/x²) x

We can then solve for the integrating factor: 1/x² + (y/x³) = x/x²

We can then solve for the integrating factor: 1/x². Therefore, the integrating factor for the given equation is 1/x².

The least square regression line equation is y = a + bx, where y is the response variable (sepal width), x is the independent or predictor variable (sepal length), a is the intercept, and b is the slope of the line.

The equation for the least square regression line is y = a + bx, where y is the dependent or response variable, x is the independent or predictor variable, a is the intercept, and b is the slope of the line. To calculate the equation for the least square regression line when the independent or predictor variable is sepal length and the dependent or response variable is sepal width for iris versicolor, the following steps should be taken: First, calculate the mean of the sepal lengths and the sepal widths. Then, calculate the variance of the sepal lengths, and the variance of the sepal widths. Next, calculate the covariance of the sepal length and sepal width. Finally, calculate the slope (b) of the regression line using the formula b = covariance/(variance of x). Once the slope is calculated, substitute it into the regression line equation to calculate the intercept (a). Using the mean of the sepal lengths and the slope and intercept, the equation for the least square regression line for the given data set can be calculated.

Answer: x=7[tex]\sqrt{3}[/tex] and y = 14

Step-by-step explanation:

The percent markup is 66.67%.

The markup is the difference between the cost price and the selling price of a product, expressed as a percentage of the cost price.

Let's call the cost price of each shirt "cp". Then, the total cost price of 200 shirts would be 200 * cp.

The selling price of each shirt is $20, so the total revenue from selling 200 shirts would be 200 * $20 = $4000.

From the information given, we know that the total cost price of 200 shirts is $2400.

Therefore, we can set up the following equation to find the cost price of each shirt:

200 * cp = $2400

Dividing both sides by 200, we get:

cp = $12

The markup is the percentage increase from the cost price to the selling price, so it can be calculated as follows:

Markup = (Selling Price - Cost Price) / Cost Price * 100%

= ($20 - $12) / $12 * 100%
