The trapezoidal rule is a numerical integration method that frequently overestimates the real value of a function's definite integral.

The trapezoidal rule is a strategy for approximating the definite integral in calculus. The trapezoidal rule works by computing the area of the region under the graph of the function f(x) that is approximated as a trapezoid. The trapezoidal rule is commonly used to calculate the area under curves. This is achievable if the overall area is divided into smaller trapezoids rather than rectangles. The Trapezoidal Rule integration determines the area by approximating the area under a function's graph as a trapezoid. The midway rule uses rectangular areas to approximate the definite integral, whereas the trapezoidal rule uses trapezoidal approximations to approximate the definite integral. Simpson's approach works by first approximating the original function with piecewise quadratic functions.

Answer:

To find the solution of a linear system, we need to find the values of x and y that satisfy both equations. One method to solve a system of linear equations is substitution. We can use the first equation to find the value of y in terms of x, and substitute it into the second equation.

y = 1/2x + 1

y = 3/2x + 4

We substitute the first equation into the second equation:

3/2x + 4 = 1/2x + 1

Now we simplify:

2x = 3

x = 3/2

Finally, we substitute x = 3/2 into either equation to find y:

y = 1/2 * 3/2 + 1 = 2

So, the solution of the system is (3/2, 2). Out of the given options, only (3/2, 7/4) has the same values of x and y.

Therefore, the answer is (C) (3/2, 7/4).

Answer: A

If you plug in -3 into X on both equations you'd get -1/2, thus showing that (-3, -1/2) is a solution to both

The original fraction is -5. Note that this is a negative fraction, which may not be meaningful in certain contexts.

Let's call the original fraction "x".

From the first condition, we have:

x + 4 / x's denominator = 3/4

From the second condition, we have:

x / (x's denominator + 2) = 1/2

We can substitute x's denominator in the first equation with (x's denominator + 2) from the second equation:

x + 4 / (x's denominator + 2) = 3/4

Next, we can cross-multiply and solve for x:

4x + 16 = 3x's denominator + 6

x's denominator = 4x + 10

Substituting back into the second equation:

x / (4x + 10) = 1/2

Multiplying both sides by (4x + 10) to isolate x:

2x = 4x + 10

Solving for x:

-2x = 10

x = -5

Infinitely many solutions exist for a system with fewer equations than unknowns, yet there may be none. An underdetermined system is one that operates in this manner.

What in mathematics is a linear system?

A collection of one or more linear equations involving the same variables is known as a system of linear equations (or linear system) in mathematics.

                          Equations with unknowns or variables that have powers of one are known as linear equations. Because the variables x, y, and z are linear, for instance, 3x - 4y + 5z = 3 is a linear equation, however xy + 3z = 7 is not because the phrase xy is a product of two variables.

The solution is, by force wind move the sail.

As the boat is sailing, the wind will be faster than the boat. This fast wind is obstructed by the sail. That is, the fast wind gets slowed down by the sail because the sail pushes the wind backwards which slows down the wind. This will make the wind push the boat forward thereby accelerating the boat.

here, we have,

Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.

The equation of the perpendicular line is y = -4/3 x + 12.

The equation of the parallel line is y = 3/4 x + 2.

Perpendicular lines are two lines that cross one other and create a 90-degree angle.

Consider the line y= (3/4)x+6.

To find the equation of the line that is perpendicular to the line y = (3/4)x + 6 and passes through the point (-8, -4), we need to find the slope of the perpendicular line.

Since the slope of a line perpendicular to another line is the negative reciprocal of the original line.

The slope of the line y = (3/4)x + 6 is m = 3/4.

Therefore, the slope of the perpendicular line is -4/3.

Plugging in the values we have, we get:

y - (-4) = -4/3 (x - (-8))

Simplifying, we get:

y + 4 = -4/3 x + 8

y = -4/3 x + 12

So the equation of the perpendicular line is y = -4/3 x + 12.

To find the equation of the line that is parallel to the line y = (3/4)x + 6 and passes through the point (-8, -4), we need to use the same slope, m = 3/4, as the original line.

Using the point-slope form of a line, we get:

y - (-4) = 3/4 (x - (-8))

Simplifying, we get:

y + 4 = 3/4 x + 6

y = 3/4 x + 2

So the equation of the parallel line is y = 3/4 x + 2.

By using the formula for permutation, we can find that there are 2,598,960 possible combinations of 5 cards that can be dealt from a standard deck of 52 cards.

Poker is a popular card game that is played with a standard deck of 52 cards.

A permutation is the arrangement of objects in a specific order. In this case, the objects are the 52 cards in a standard deck, and the order is the 5 cards that are dealt to each player.

To find the number of possible 5-card hands, we can use the formula for permutation:

P(52, 5) = 52! / (52 - 5)!

Where "52!" is the factorial of 52, meaning the product of all positive integers from 1 to 52.

52! / (52 - 5)! = 806,368,039,360 / 47! = 2598960

The final answer is that there are 2,598,960 possible 5-card hands that can be dealt from a standard deck of 52 cards.

The equation of a circle with center at the origin (0, 0) can be written as:

, where r is the radius of the circle.

Since the circle passes through the point (5, -8), we can substitute these values into the equation of the circle to find the radius:

[tex](5-0)^{2} (-8-0)^{2}= r^{2}[/tex]

25 + 64 = r^2

[tex]r^{2}[/tex]= 89

r = sqrt(89) = 3 sqrt(89)

So, the equation of the circle with center at the origin and passing through (5, -8) is:

(x - 0)^2 + (y - 0)^2 = (3 sqrt(89))^2

The distance of the run is 11.67 miles.

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Given that,

Speed of first jogger = 5 mph

Speed of second jogger = 4 mph

Let d be the distance in miles of the run.

Time taken by first jogger be t hours.

Time taken by second jogger = t + (35 minutes) = t + (7/12) hours

Speed = Distance / Time

5 = d / t and 4 = d / (t + 7/12)

d = 5t and d = 4 (t + 7/12)

5t = 4 (t + 7/12)

5t = 4t + 7/3

t = 7/3 hours

d = 5t = 11.67 miles.
