An integral expression that provides the solid's volume at the points y=x, y=2, and x=6 is [tex]\int\limits^{6}_{2} {y^3} \, dy[/tex]

How many areas of space are filled by an object is determined by its volume. The amount of unit cubes required to completely fill the solid serves as the measurement. By counting the solid's unit cubes, the answer can be determined.

A three-dimensional object's volume is typically thought of as its ability to accommodate matter.

According to the question,

The cross section of the solid taken perpendicular to the y- axis is a square.

Solid base equation: y=x, y=2, x=6

Square Volume = (Side3)

Since y = x in the equation and y = 2 as a result, x must equal 2.

So , Limit of x varies from 2 to 6

Volume of solid is  [tex]\int\limits^{6}_{2} {y^3} \, dy[/tex]

Hence , , an integral expression that gives the volume of the solid is [tex]\int\limits^{6}_{2} {y^3} \, dy[/tex]

The amount of gun powder particles found around a bullet hole is directly related to the distance from which the weapon was fired.

Which two forces are acting on a bullet?

Two major forces are acting on the bullet ,the forward force of the gunshot and the downward force of gravity. The first force is called aerodynamics and the other force is called gravitational.

What does the distribution of gun powder residue around the bullet hole help to determine?

The residue exit the muzzle in a cone shaped and can land on the target objects. The size and density of the residue on the object can vary with distance allowing the fire man examiner to determine proximity of shooter to the target killing when gun is fired.

Therefore, the amount of gun powder particles found around a bullet is directly related to the distance when gun was fired.

The distance ship travelled 7.4 units between the two observations of the lighthouse.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c

Given that, a ship is sailing due north. At a certain point the bearing of a lighthouse is N39.8˚E and the distance is 11.5.

P is the ship, R is the light house and Q is the bearing.

PR is the distance between the ship and the light house, PR = 11.5

∠P = 43.5°, ∠Q =39.8°

Thus, ∠R = 180° -∠P-∠Q

= 180°-43.5°-39.8°

= 96.7°

By using sin rule we get

PR/sinR =PQ/sinQ

11.5/sin96.7° =PQ/sin39.8°

11.5/0.9931 =PQ/0.6401

PQ/0.6401=11.55

PQ=7.4 units

Therefore, the distance ship travelled 7.4 units between the two observations of the lighthouse.

Nonlinear solver method used in the slope of the objective function as the input values changes. It determines that it reached at the optimum solution when the initial value is equals to zero.

In the nonlinear solver method, the initial values  used within one of the nonlinear equation.  By default the initial value chosen for all variables is zero or the lower bound. zero is in many cases is a bad initial value for a nonlinear variable. For example, if the variable appears in a product term since the initial derivative becomes zero, and it appears as if the function does not depend on the variable. When the equation is simple, the value of x can be determined analytically. This is used in the case when x can be written explicitly by applying mathematical operations or when a known formula such as the formula for solving a quadratic equation can be used to determine the exact value of x.

The solution to the trigonometric equation is sin( 6x ) = 2sin(3x)cos(3x)

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the equation be represented as A

Now , the value of A is

A = sin (6x)

From the trigonometric relations ,

The value of sin( 2x ) = 2sin(x)cos(x)

Now , when x is replaced by 6x

Substituting the values in the equation , we get

sin ( 6x ) = 2 sin ( 6x/2 ) cos ( 6x/2 )

On simplifying the equation , we get

sin ( 6x ) = 2 sin ( 3x ) cos ( 3x )

So , the value of the trigonometric relation is

sin(6x) = 2sin(3x)cos(3x)

Hence , the equation is sin(6x) = 2sin(3x)cos(3x)

It's easier to come up with the correctness proof of the divide and conquer algorithm compared to the greedy algorithm is False statement.

It is not easier to come up with a correctness proof of the divide and conquer algorithm compared to the greedy algorithm. The correctness proof of a divide and conquer algorithm is more difficult than a greedy algorithm since it involves breaking down an algorithm into multiple sub-problems and then proving the correctness of the algorithm with respect to each sub-problem. On the other hand, the correctness proof of a greedy algorithm is relatively simple and involves determining if a given solution is optimal. Additionally, the correctness proof of a divide and conquer algorithm requires more complex mathematical analysis such as induction, recurrence relations, or complexity analysis. This makes it more difficult to come up with the correctness proof of the divide and conquer algorithm than the greedy algorithm.

The graph of cubic equations, a to d and the associated cubic equations are as follows;

Equation (B) ⇒ Graph a

Equation (C)  ⇒ Graph b

Equation (D) ⇒ Graph c

Equation (A) ⇒ Graph d

A cubic equation that has only one variable is an equation of the form a·x³ + b·x² + c·x + d, where a ≠ 0.

The evaluation of the graphs are as follows;

Graph a

The y-intercept of the graph a, is 1, and the x-intercept, which is a solution of the equation is x = -1,

Therefore, when x = 0, y = 1, and when y = 0, x = -1

The function in graph a represents the translation of the parent function, y = x³, one unit, upwards, which corresponds with the function;

y = x³ + 1

Therefore, graph a corresponds to cubic equation (B) y = x³ + 1

Graph b

The y-intercept is one (1), and the turning point is at the point x = -1, which represents a shift of one unit to the left, and which can be obtained by the equation; y = (x + 1)³

Therefore, graph b corresponds with the cubic equation (C) y = (x + 1)³

Graph c

The turning point of the graph and the y-intercept is shifted one unit down, which corresponds with the equation; (D) y = x³ - 1

Graph d

The turning point is shifted 1 unit to the right and is located on the x-axis, The y-intercept is located at the point y = 1, therefore, the graph corresponds with the equation y = (x - 1)³

Graph d corresponds to equation (A), y = (x - 1)³
