The result will be the x value when the difference between the values of f(x) and g(x) is less than 0.1, which will be the positive solution to the nearest tenth of f(x)=g(x).

To find the positive solution, to the nearest tenth, of f(x)=g(x) using Cora's process, the steps are as follows:

Input the initial value of x, for example x=0.

Calculate f(x) and g(x):

If f(x) is less than g(x), then x should be increased and vice versa.

Increase or decrease x accordingly and calculate the new values of f(x) and g(x).

Keep repeating steps 3 and 4 until the difference between the values of f(x) and g(x) is less than 0.1.

The result will be the x value when the difference between the values of f(x) and g(x) is less than 0.1, which will be the positive solution to the nearest tenth of f(x)=g(x).

Minimum surface area of rectangular bin with 62,500 cm^3 volume and square base is 31250 cm^2.

What is rectangle ?

A rectangle is a two - dimensional shape with four sides, where each pair of opposite sides are equal in length and parallel to each other

Let's say the length, width and height of the rectangular bin are l, w and h respectively. The volume of the bin can be expressed as:

V = l * w * h = 62500 cm^3 (Given)

Since the base is a square, have w = l. Therefore,

V = l^2 * h

h = V / l^2 = 62500 / l^2

The surface area of the bin can be expressed as:

A = 2lw + 2lh + 2wh

Substituting the value of w = l and h = V / l^2, get:

A = 2l^2 + 2l * (V / l^2) + 2l * l = 2l^2 + 2V / l + 2l^2 = 4l^2 + 2V / l

To minimize the surface area, differentiate A with respect to l and set it to zero:

dA/dl = 8l + 2V / l^2 = 0

4l^3 = V

l^3 = V / 4

Taking the cube root of both sides,

l = (V / 4)^(1/3)

Substituting the value of V,

l = (62500 / 4)^(1/3) = (15625)^(1/3) = 125 cm

Since w = l,

w = 125 cm

h = V / l^2 = 62500 / (125)^2 = 250 cm

The minimum surface area is then given by,

A = 2lw + 2lh + 2wh = 2 * 125 * 125 + 2 * 125 * 250 + 2 * 125 * 125 = 31250 cm^2

Minimum surface area of rectangular bin with 62,500 cm^3 volume and square base is 31250 cm^2.

Let's say the length, width and height of the rectangular bin are l, w and h respectively. The volume of the bin can be expressed as:

V = l * w * h = 62500 cm³ (Given)

Since the base is a square, have w = l. Therefore,

V = l² * h

h = V / l² = 62500 / l²

The surface area of the bin can be expressed as:

A = 2lw + 2lh + 2wh

Substituting the value of w = l and h = V / l^2, get:

A = 2l² + 2l * (V / l²) + 2l * l = 2l²+ 2V / l + 2l² = 4l² + 2V / l

To minimize the surface area, differentiate A with respect to l and set it to zero:

dA/dl = 8l + 2V / l² = 0

4l³ = V

l³ = V / 4

Taking the cube root of both sides,

The given matrix is in row echelon form, meaning that the leading entry of each non-zero row is to the right of the leading entry of the previous row. In this form, the solution to the linear system can be found by back substitution.

Starting from the bottom row, we have the equation:

-1 * x4 + 4 * x5 = -1

Solving for x4, we have:

x4 = -4 * x5 + 1

Moving up to the next row, we have:

0 * x1 + 0 * x2 + 3 * x5 = 3

Solving for x5, we have:

x5 = 1

So, x4 = -4 * 1 + 1 = -3.

Next, the third row gives us:

0 * x1 + 0 * x2 - 3 * x3 + 4 * x4 = 4

Substituting the value of x4, we have:

0 * x1 + 0 * x2 - 3 * x3 + 4 * (-3) = 4

Solving for x3, we have:

x3 = -1

Since there are no more non-zero rows in the matrix, we have found a complete solution for the linear system.

The solution set of the original system is the set of all possible values of (x1, x2, x3, x4, x5) that satisfy the system of equations represented by the matrix. Since the given matrix is in row echelon form, this solution set is unique and consists of a single point in the 5-dimensional space.

The minimum payment in the first month would be:

Minimum payment = 1.5% * $19,500 + 3% * $19,500 = $292.25

At the end of the first month, the balance would be:

Balance = $19,500 + $19,500 * 1.5% - $292.25 = $19,318.375

In the second month, the minimum payment would be:

Minimum payment = 1.5% * $19,318.375 + 3% * $19,318.375 = $291.26

At the end of the second month, the balance would be:

Balance = $19,318.375 + $19,318.375 * 1.5% - $291.27 = $19,138.89

In the third month, the minimum payment would be:

Minimum payment = 1.5% * $19,138.89 + 3% * $19,138.89 = $290.26

For a particle having a position of function e^-(t - 3)², the velocity at 2.9s is obtained as 0.198008 m/s.

What is velocity?

The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction. Since it is a vector quantity, the definition of velocity requires both magnitude (speed) and direction.

The position of a particle is denoted by a function x(t) = e^-(t - 3)², where x is the distance and t is the time.

Differentiate the function -

v(x) = d/dt(x) = d/dt[e^-(t - 3)²]

v(x) = e^-(t - 3)²[-2(t - 3)]

Now, substitute the value of t = 2.9 in the equation -

v(2.9) = e^-(2.9 - 3)²[-2(2.9 - 3)]

v(2.9) = e^-(-0.1)²[-2(-0.1)]

Use the exponent formula a^-b = 1/a^b -

v(2.9) = 1/e^(-0.1)²[0.2]

Square the digit (0.1) -

v(2.9) = 1/e^(0.01)[0.2]

Substitute the value ofe^0.01 = 1.01005 -

v(2.9) = (1/1.01005)[0.2]

Use the arithmetic operation of division -

v(2.9) = (0.99004)[0.2]

v(2.9) = 0.198008

Therefore, the velocity of the particle is 0.198008 m/s.

What is a histogram?

A histogram is a representation of statistical data that makes use of rectangles to display the frequency of data items in a series of equal-sized numerical intervals. The independent variable is plotted along the horizontal axis and the dependent variable is plotted along the vertical axis in the most popular type of histogram.

Left-skewing histograms: As seen in the example below, some histograms will have a left-skewing distribution. Negatively skewed refers to a distribution that is skewed to the left. There are many instances of this type of distribution on the right side's upper-value cells, while there are few instances on the left side's lower-value cells (left side). When information is gathered from a system with a boundary, such as 100, a skewed distribution, such as 100, can result. In other words, none of the data that was gathered has values greater than 100.

Some histograms will display a distribution that is skewed to the right, as shown below. Positive skewness refers to a distribution that is skewed to the right. Large numbers of occurrences in the lower-value cells (left side) and few in the upper-value cells characterize this type of distribution (right side). When information is gathered from a system with a boundary like zero, the distribution may become skewed. In other words, all the data that was gathered has values that are greater than 0.

Explanation:

1) subtract “1” from both sides to get y by itself

Y=-2x-1

2) 4y+8x=-4 share a gcf of “4” so you can divide the whole equation by 4

y+2y=-1

Now substitute “-2x-1” as y

(-2x-1)+2x=-1

-2x and 2x cancel each other and so does -1 and -1

Hence, this system has infinitely many solutions

Answer:

x = 0, y = 1.

Step-by-step explanation:

We can solve for the variables x and y by using substitution. Let's start by solving the first equation for one of the variables:

-1 = 2x - y

y = 2x + 1

Next, we'll substitute y = 2x + 1 into the second equation:

8x - 4y = -4

8x - 4(2x + 1) = -4

Expanding the second equation:

8x - 8x - 4 = -4

-8x - 4 = -4

-8x = 0

x = 0

Finally, we can use one of the equations to find y:

y = 2x + 1

y = 2(0) + 1

y = 1

So, the solution is x = 0, y = 1.

To start, you need to declare an array variable that can store 10 integers. For example, you can declare an array variable called "numbers" as follows:

int numbers[10];

Next, you will use a loop to repeatedly ask the user to input an integer. The loop will run 10 times to receive 10 integers. You can use the for loop for this purpose.

Here is an example:

for (int i = 0; i < 10; i++) {

 printf("Enter integer %d: ", i + 1);

 scanf("%d", &numbers[i]);

}

In this code, the for loop starts with the value of i being 0. It runs until i is less than 10. After each iteration, i is incremented by 1.

After the loop finishes, all 10 integers received from the user are stored in the numbers array. You can access them using the index of the array.

In conclusion, to receive 10 integers from the user using an array and a loop, you need to declare an array variable, use a for loop to repeatedly ask the user for input, and store the input in the array using the scanf function.

Answer: 2

Step-by-step explanation:The slope of a line is the ratio of the change in y-values to the change in x-values between two points on the line.

To find the slope, we first need to find two points on the line, for example (4,12) and (7,18).

Then, the slope can be calculated as:

(18 - 12) / (7 - 4) = 6 / 3 = 2.

The slope is 2.
