The equation of the trend line in the scatter plot is y = (6/5)x - 12/5.

We can use the two-point form of the equation of a line to find the equation of the line that passes through the points (2, 0) and (7, 6).

The two-point form states that the equation of the line passing through two points (x1, y1) and (x2, y2) is given by:

y - y1 = (y2 - y1)/(x2 - x1) * (x - x1)

where m = (y2 - y1)/(x2 - x1) is the slope of the line.

In this case, we have:

x1 = 2, y1 = 0

x2 = 7, y2 = 6

So, the slope of the line is:

m = (y2 - y1)/(x2 - x1) = (6 - 0)/(7 - 2) = 6/5

Now, we can use either point to find the y-intercept (b) of the line. Let's use the first point (2, 0):

y - y1 = m(x - x1)

y - 0 = (6/5)(x - 2)

y = (6/5)x - 12/5

Therefore, the equation of the line passing through the points (2, 0) and (7, 6) is y = (6/5)x - 12/5.

  x :        0     2      4      6

f ( x ) :    3      2      1     0

f ( x ) = 3 - x/2

Answer: B ) f ( x ) = -1/2 x + 3

Step-by-step explanation:

Answer:

Answer:

D

Step-by-step explanation:

The y-coordinate will be the average of 5 and -2 which is 3/2. This eliminates options A and B. C doesn't make sense because the x-coordinate (which is -7) of the midpoint can't be larger or smaller than the x-coordinates of the endpoints, so that means that the answer is D.

An ordered pair that is not marked on the coordinate plane of this graph is (8, 0).

In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which represent the x-coordinate (x-axis) and y-coordinate (y-axis) respectively.

An ordered pair can be defined as a pair of two (2) data points that are commonly written in a fixed order within parentheses as (x, y), in order to represent the x-coordinate or x-axis (abscissa) and the y-coordinate or y-axis (ordinate) on the coordinate plane of any graph.

By critically observing the given graph, we can reasonably and logically deduce that data point (8, 0) is the missing ordered pair on the coordinate plane.

The surface area is increasing at the rate of (60 x + 150) cm² per second.

Let the side of the cube be x cm.

s = x cm

Surface area of the cube will be:

S = 6 x² cm²

Now, we are given that, the side of the cube is expanding 5 cm per second.

So, the side of the cube after 1 second will be:

s' = x + 5 cm

Surface area will be:

S' = 6 (x + 5)² cm²

S' = (6x² + 150 + 60 x) cm²

Change in the surface area is:

ΔS = (6x² + 150 + 60 x) cm² - 6 x² cm²

ΔS = (60 x + 150) cm²

Therefore, the surface area is increasing at the rate of (60 x + 150) cm² per second.

Answer:

Step-by-step explanation:

The given pair of ODEs can be solved using Euler's method and the second-order Runge-Kutta (RK2) method to approximate the solutions numerically.

To solve the given pair of ODEs using Euler's method and the second-order Runge-Kutta (RK2) method, we'll consider the equations:

1) y' = f(t, y, z)

2) z' = g(t, y, z)

with the initial conditions y(0) = 2 and z(0) = 4.

a) Euler's Method:

In Euler's method, we approximate the derivatives using forward difference approximations and update the solution iteratively. The general update formulas are:

y[i+1] = y[i] + h * f(t[i], y[i], z[i])

z[i+1] = z[i] + h * g(t[i], y[i], z[i])

where h is the step size and t[i] represents the current time.

Using a step size of h = 0.1, we can perform the calculations as follows:

At t = 0:

y[0] = 2

z[0] = 4

Using the update formulas, we can calculate the values of y and z at each time step. We repeat this process until we reach the desired end time (t = 0.4 in this case).

b) Second-Order Runge-Kutta (RK2) Method:

In the RK2 method, we use weighted averages of slopes to update the solution. The general update formulas are:

k1 = h * f(t[i], y[i], z[i])

l1 = h * g(t[i], y[i], z[i])

k2 = h * f(t[i] + h/2, y[i] + k1/2, z[i] + l1/2)

l2 = h * g(t[i] + h/2, y[i] + k1/2, z[i] + l1/2)

y[i+1] = y[i] + k2

z[i+1] = z[i] + l2

Again, using a step size of h = 0.1, we can perform the calculations iteratively until we reach t = 0.4.

These methods provide numerical approximations to the solutions of the given ODEs. The accuracy of the approximations depends on the step size chosen. Smaller step sizes generally result in more accurate solutions but require more computational effort.

Answer:

Todos esses outros números são divisores e os fatores de 24 são 2 e 3. Para fatorar um número devemos dividi-lo por números menores começando pelo 2 e ir aumentando, até restar 1.

Step-by-step explanation:

In a case whereby the sum of two consecutive numbers is 25 the largest of the consecutive numbers is 13.

Given that sum of two consecutive numbers is 25 , ans we were required to locatye the  largest of the consecutive numbers. The we can represent the consecutive numbers as x and x+1. According to the problem, the sum of these two consecutive numbers is 25:

x + (x+1) = 25

Simplifying the left side of the equation:

2x + 1 = 25

2x = 24

Dividing both sides by 2:

x = 12

So the first consecutive number is 12. The second consecutive number is 12 + 1 = 13. Therefore, the largest of the consecutive numbers is 13.

Answer:

The correct answer is 4,672.18.

Step-by-step explanation:

To solve this problem, we must look at the number we are given and determine what numbers are in which places.  The 4 is in the thousands place, the 6 is in the hundreds place, the 7 is in the tens place, the 2 is in the ones place, the 1 is in the tenths place, the 8 is in the hundredths place, and the 3 is in the thousandths place.  

The question asks us to round to the nearest hundredth, so this means that the number in the hundredths place should be the final digit.  In the number given, the number 8 is in the hundredths place.  Since the following digit (3) is less than 5, we round down and keep the 8 in the hundredths place.  This makes our answer 4,672.18.

To find the derivatives of the given expressions, we can apply the chain rule, which states that the derivative of a composition of functions is equal to the derivative of the outer function multiplied by the derivative of the inner function.

(a) To find the derivative of f(g(x)), we start by differentiating the outer function f with respect to the inner function g(x), and then multiply it by the derivative of the inner function g(x) with respect to x.

df/dx = df/dg * dg/dx

df/dx = cos(g(x)) * (2x)

(b) To find the derivative of g(f(x)), we differentiate the outer function g with respect to the inner function f(x), and then multiply it by the derivative of the inner function f(x) with respect to x.

dg/dx = dg/df * df/dx

dg/dx = 2f(x) * cos(x)

Hence, the derivatives are:

(a) d/dx(f(g(x))) = cos(g(x)) * (2x)

(b) d/dx(g(f(x))) = 2f(x) * cos(x)

In general, when dealing with probability, it is important to consider the context and any relevant information before making any conclusions or decisions based on the probabilities.

Probability is a measure of the likelihood or chance that a particular event will occur. It is a mathematical concept used in statistics, mathematics, and science to help predict the outcome of experiments or events based on data and past experience. The probability of an event is expressed as a number between 0 and 1, where 0 means that the event is impossible, and 1 means that the event is certain to occur.

Here,

However, here are a few possible statements that could be true:

If the spinner has only two colors, pink and green, then the probability of landing on pink is 18/100 or 9/50.

If the spinner has more than two colors, and pink is one of them, then the probability of landing on pink may or may not be high, depending on the number of colors and their respective probabilities.

If the spinner is biased or weighted, then the probability of landing on pink may not be exactly 18/100, and may be influenced by external factors such as the force of the spin or the design of the spinner.

The number of dime and the number of quarters that Aiden have are 10 and 8 respectively.

Aiden ha $3 worth of dime and quarter. Aiden has 2 more dime than quarter. The number of dime and the number of quarter that Aiden has can be calculated as follows:

let

x =  number of quarter

y = number of dime

Therefore,

y = 2 + x

y - x = 2

0.1y + 0.25x = 3

Multiply equation(ii) by 10

y - x = 2

y + 2.5x = 30
