The average velocity is given by the displacement during the time thus,[3, 4]: Average Velocity = 40 m/s. [3, 3.5]: Average Velocity = 40 m/s. [3, 3.1]: Average Velocity = 40 m/s. [3,3.01]: Average Velocity = 40 m/s.

Unaffected by direction, speed is a scalar quantity that describes how quickly an object is travelling. The speed and direction of an object's motion are both described by its velocity, which is a vector quantity. In other terms, velocity is the rate of positional change of an object in a specific direction. Therefore, if two objects are travelling in separate directions or if one is accelerating while the other is not, they can have the same speed but distinct velocities.

The average velocity is given by the displacement during the time, thus we have:

Displacement = h(t2) - h(t1) = (40t2 - 0.8312) - (40t1 - 0.8312) = 40(t2 - t1)

Now, the average velocity between t2 - t1 is:

Average Velocity = Displacement / Duration = 40(t2 - t1) / (t2 - t1) = 40 m/s

Using the different values of t2 and t1 we see that:

[3, 4]:

Average Velocity = 40 m/s

[3, 3.5]:

Average Velocity = 40 m/s

The sum of all solutions to the equation 2cos²(x) - 7cos(x) - 4 = 0 for 0 < x < 2π is approximately 9.425 + 2π.

In mathematics, a quadratic is a polynomial expression of the second degree, meaning it contains one or more terms that are squared but no terms that are cubed or higher. Quadratic functions are typically written in the form ax² + bx + c, where a, b, and c are constants and x is the variable.

To find the sum of all solutions to the equation 2cos²(x) - 7cos(x) - 4 = 0 for 0 < x < 2π, we can first use the quadratic formula to solve for cos(x):

cos(x) = [7 ± √(7² - 4(2)(-4))] / (2(2))

cos(x) = [7 ± √89] / 4

The two possible solutions for cos(x) are:

cos(x) = (7 + √89) / 4

cos(x) = (7 - √89) / 4

Note that for 0 < x < 2π, the cosine function has values between -1 and 1. Therefore, the first solution cos(x) = (7 + √89) / 4 is not valid, since it is greater than 1.

The second solution cos(x) = (7 - √89) / 4 is valid, since it is between -1 and 1. Therefore, the sum of all solutions to the equation is:

x = cos⁻¹[(7 - √89) / 4] + 2πn, where n is an integer.

We need to find the sum of all possible values of x for 0 < x < 2π. We can do this by finding the smallest and largest values of n that give valid solutions, and then summing the corresponding values of x.

The smallest value of n that gives a valid solution is n = 0, since cos⁻¹[(7 - √89) / 4] is already between 0 and 2π. The largest value of n that gives a valid solution is n = -1, since adding 2π to cos^(-1)[(7 - √89) / 4] gives a value greater than 2π.

Therefore, the sum of all solutions to the equation is:

89) / 4 - 2π]

x = cos⁻¹[(7 - √89) / 4] + cos⁻¹[(7 - √

x ≈ 6.2832 + 0.8429 + 2π

x ≈ 9.425 + 2π

The sum of all solutions to the equation 2cos²(x) - 7cos(x) - 4 = 0 for 0 < x < 2π is approximately 9.425 + 2π.

It is often used to measure the amount of gasoline or other fuels used in vehicles, as well as the amount of water in swimming pools or storage tanks.

Let's call the total capacity of Boris's gas tank "x". We know that when the tank is half full, it contains 1/2x gallons of gas. After Boris buys 3 gallons of gas, the tank is 2/3 full, which means it contains 2/3x gallons of gas. We can set up an equation to solve for x:

1/2x + 3 = 2/3x

To solve for x, we need to isolate it on one side of the equation. We can do this by first subtracting 1/2*x from both sides:

3 = 2/3x - 1/2x

To simplify the right side, we need to find a common denominator. The smallest common denominator of 2 and 3 is 6, so we can rewrite the fractions as:

3 = (4/6)*x - (3/6)*x

Now we can combine the terms on the right side:

3 = (1/6)*x

To solve for x, we can multiply both sides by 6:

x = 18

The reflection line  that maps polygon ABCDE to polygon A' B' C' D' E' is the y-axis.

The image is reflected through a line known as a reflection line. A pattern is said to mirror another pattern, and then every point in the pattern is equidistant from every corresponding point in the other pattern. The reflected image must be the same shape and size, but the image is in the opposite direction.

In order to determine the line of reflection that maps  polygon ABCDE to polygon A' B' C' D' E', we must find a symmetrical line  equidistant from each corresponding pair of points. If you project the image across the x-axis, vertex A (-1, -4) is mapped to A' (13, -4) and vertex E (1, -6) is mapped to E'. (11, 6). Therefore, the reflection line must be the x-axis.

If we map the image to the cross x=6, vertex A (-1, -4) would correspond to A' (13, -4) and vertex E (1, -6) would correspond to E' (3, 6). ). Therefore, the reflection line cannot be x=6.

If we project the pattern perpendicular to y=-3, the point A (-1, -4) is opposite to the point A' (-7, -4) and the vertex E (1, -6)  to  the point E . (7, 6). Therefore, the reflection line  cannot be y=-3.

The equation of a circle in standard form with a center at (h, k) and a radius r is:

(x - h)² + (y - k)² = r²

Center: (h, k) = (-6, 5)

Point on circle: (-11, 3)

Substituting these values into the standard form equation:

What is circle?

A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center. It can also be defined as the set of points that are a fixed distance (called the radius) away from the center point.

I'm sorry, but the answer you provided is not correct.

To find the length of the arc, you first need to determine what fraction of the circle the sector represents. The central angle is 36 degrees, which is 36/360 or 1/10 of the full circle.

To find the length of the arc, you can then use the formula:

arc length = (central angle/360) x 2πr

where r is the radius of the circle.

Plugging in the values you provided, we get:

arc length = (36/360) x 2π(12) = 2.4π inches

Rounding to the nearest tenth gives:

arc length ≈ 7.5 inches

The probability of success for given number of trials is 0.4751.

What is probability?

Probability can be used to determine the likelihood of an event. The likelihood that an event will happen is the only useful outcome. a scale where 0 indicates impossibility and 1 indicates a specific occurrence.

We know that the probability is given by:

P = nCx * [tex]p^{x}[/tex] * [tex]q^{n-x}[/tex]

P (x ≤ 3) = P(0) + P(1) + P(2) + P(3)

Now,

⇒ P(0) = 7C0 * [tex]0.4^{0}[/tex] * [tex]0.6^{7}[/tex]

⇒ P(0) = 1 * 1 * 0.0279936

⇒ P(0) = 0.02799

Similarly,

⇒ P(1) = 7C1 * [tex]0.4^{1}[/tex] * [tex]0.6^{6}[/tex]

⇒ P(1) = 7 * 0.4 * 0.046656

⇒ P(1) = 0.13064

Similarly,

⇒ P(2) = 7C2 * [tex]0.4^{2}[/tex] * [tex]0.6^{5}[/tex]

⇒ P(2) = 21 * 0.16 * 0.07776

⇒ P(2) = 0.02613

Similarly,

⇒ P(3) = 7C3 * [tex]0.4^{3}[/tex] * [tex]0.6^{4}[/tex]

⇒ P(3) = 35 * 0.064 * 0.1296

⇒ P(3) = 0.2903

So, now we get

⇒ P (x ≤ 3) = P(0) + P(1) + P(2) + P(3)

⇒ P (x ≤ 3) = 0.02799 + 0.13064 + 0.02613 + 0.2903

⇒ P (x ≤ 3) = 0.4751

Hence, the probability of success for given number of trials is 0.4751.

The height of the plane above the ocean is approximately 15,000 meters to the nearest meter.

The angle of depression is an angle formed between a horizontal line (such as the ground, ocean surface, or any other reference plane) and a line of sight from an observer looking downward towards an object or point of interest that is located below the observer's line of sight.

According to the given information:

The angle of depression is the angle formed between the horizontal line (such as the ocean's surface) and the line of sight from an observer looking downward to an object (such as the island). In this case, the angle of depression is given as 45 degrees.

Given:

Angle of depression = 45 degrees.

Distance from airplane to island = 15,000 meters.

To find the height of the plane, we can use trigonometry. The tangent function is commonly used to relate angles of depression to the height of an object above the horizontal.

In a right triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. In this case, the side opposite the angle of depression is the height of the plane, and the side adjacent to the angle is the distance from the airplane to the island.

Using the tangent function:

tan(angle of depression) = height of plane/distance to the island

Plugging in the given values:

tan(45 degrees) = height of plane / 15,000 meters

We can now solve for the height of the plane:

height of plane = tan(45 degrees) * 15,000 meters

Using a calculator, we find:

height of plane = 15000 * tan(45 degrees) ≈ 15000 meters (rounded to the nearest meter)

So, the height of the plane above the ocean is approximately 15,000 meters to the nearest meter.

We can start by using the identity 2 sin ϕ cos ϕ = sin 2ϕ to simplify the left-hand side of the equation:

2 sin ϕ cos ϕ + 2 sin ϕ + cos ϕ + 1 = sin 2ϕ + 2 sin ϕ + cos ϕ + 1

Next, we can use another identity, sin^2 ϕ + cos^2 ϕ = 1, to eliminate the cosine term:

sin 2ϕ + 2 sin ϕ + cos ϕ + 1 = sin 2ϕ + 2 sin ϕ + √(1 - sin^2 ϕ) + 1

Now, we can substitute u = sin ϕ to obtain a quadratic equation in u:

sin 2ϕ + 2 sin ϕ + √(1 - sin^2 ϕ) + 1 = sin^2 ϕ + 2 sin ϕ + √(1 - sin^2 ϕ) + 1

sin 2ϕ = sin^2 ϕ

2 sin ϕ cos ϕ = sin^2 ϕ - cos^2 ϕ

2 u √(1 - u^2) = u^2 - (1 - u^2)

2 u √(1 - u^2) = 2 u^2 - 1

4 u^2 (1 - u^2) = (2 u^2 - 1)^2

4 u^4 - 4 u^2 + 1 = 0

This is a quadratic equation in u^2, which can be solved using the quadratic formula:

u^2 = [4 ± √(16 - 16)] / 8 = 1/2 or u^2 = 1

Since 0 < ϕ < 2π, we have 0 < u < 1, so u^2 = 1/2. Therefore, sin ϕ = u = ±√(1/2) and cos ϕ = ±√(1 - u^2) = ±√(1/2).

We can summarize the solutions as follows:

sin ϕ = √(1/2) or sin ϕ = -√(1/2)

cos ϕ = √(1/2) or cos ϕ = -√(1/2)

So, the length of WZ is 24 in kite WXYZ with diagonals WY and XZ.

A triangle is a closed, two-dimensional geometric shape that is formed by three line segments, called sides, that intersect at three points, called vertices. Triangles are one of the most basic shapes in geometry and are studied extensively in mathematics. The properties of triangles depend on the length of their sides and the size of their angles. Triangles can be classified based on the length of their sides as equilateral, isosceles, or scalene, and based on the size of their angles as acute, right, or obtuse. In an equilateral triangle, all three sides are of equal length. In an isosceles triangle, two sides are of equal length, while the third side is of a different length. In a scalene triangle, all three sides are of different lengths.

Here,

Since WXYZ is a kite, we know that its diagonals, WY and XZ, intersect at a right angle and bisect each other. Let M be the point of intersection of the diagonals, so that MW = MY and MX = MZ.

We can use the Pythagorean theorem to find MW and MX, and then use the fact that they are equal to find WZ.

Using the Pythagorean theorem in right triangles WMX and WMY, we have:

MW² = WX² - MX²

= 17² - 5²

= 264

MY² = WY² - MW²

= 13² - 264

= 25

MX² = XZ² - MZ²

= 17² - 13²

= 144

Since MW = MY, we have MW = √(25)

= 5

Therefore, WZ = 2MX

= 2√(144)

= 2*12

The image coordinates of L′ are L′(-1, 2).

What are Transformation and Reflection?

Single or multiple changes in a geometrical shape or figure are called Geometrical Transformation.

A geometrical transformation in which a geometrical figure changes his position to his mirror image about some point or line or axis is called Reflection.

To reflect the preimage of point L across the line y = -2, we need to find the distance between L and the line y = -2 and then move that same distance above the line to get the image L′.

The distance between point L and the line y = -2 is 4 units (since the y-coordinate of point L is -6 and the y-coordinate of the line y = -2 is -2).

So, to get the image L′, we move 4 units above the line y = -2 starting from the x-coordinate of L, which is -1. This gives us the coordinates (-1, 2).

Therefore, the image coordinates of L′ are L′(-1, 2).

y = - | 2-2| + 2
⇒ - 1+ 2

y = 1

At x = 3:

y = - | 3-2| + 2
⇒ - 1+ 2

y = 1

At x = 4:

y = - | 4-2| + 2
⇒ - 2+ 2

y = 0

Thus,  all values of y > 0 at x = (0, 1, 2, 3, 4)
