The value of the given integral is: v = [(4√(3) - 5)π/3]

To evaluate the given integral, let's calculate it step by step:

First, let's integrate with respect to z from 1 to √(4 - x² - y²):

∫[1, √(4 - x² - y²)] dz = √(4 - x² - y²) - 1

Next, let's integrate the above expression with respect to y from -√(3 - x²) to √(3 - x²):

∫[-√(3 - x²), √(3 - x²)] (√(4 - x² - y²) - 1) dy

To simplify the integration, let's convert to polar coordinates:

x = r cosθ

y = r sinθ

The bounds of integration in polar coordinates will be:

r: 0 to √(3)

θ: 0 to 2π

Now, we can rewrite the integral in terms of polar coordinates:

∫[0, 2π] ∫[0, √(3)] (√(4 - r²) - 1) r dr dθ

Evaluating the inner integral with respect to r:

∫[0, 2π] [(-1/3) (4 - r²)\(^{3/2}\) - (1/2) r²] | [0, √(3)] dθ

∫[0, 2π] [(2√(3)/3) - (1/3)(4 - 3)\(^{3/2}\) - (1/2)(√(3))²] dθ

Simplifying further:

∫[0, 2π] [(2√(3)/3) - (1/3) - (3/2)] dθ

∫[0, 2π] [(2√(3)/3) - (5/6)] dθ

Now, integrating with respect to θ:

[(2√(3)/3)θ - (5/6)θ] | [0, 2π]

[(2√(3)/3)(2π) - (5/6)(2π)] - [(2√(3)/3)(0) - (5/6)(0)]

[(4√(3)/3)π - (5/3)π] = [(4√(3) - 5)π/3]

Therefore, the value of the given integral is: v = [(4√(3) - 5)π/3]

Evaluate the integral:

Answer:

Length of hypotenuse \(12\sqrt2\) cm.

Step-by-step explanation:

We are given with a right angled triangle which has angles 45°-45°-90° and sides as 12 cm each.

Following labeling of dimensions is provided:

\(\angle XYZ = 90^\circ\\\angle YZX = 45^\circ\\\angle ZXY = 45^\circ\)

Sides:

ZY = 12 cm

YX = 12 cm

Please refer to the image attached as well.

To find: The hypotenuse, XZ = ?

It is well known that if the triangle is a right angled triangle, the pythagorean theorem holds well. As per the theorem:

\(\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Height}^{2}\\\)

Here, Base is ZY = 12 cm

Height, YZ = 12 cm

And Hypotenuse XZ is to be calculated.

Putting the values:

\(XZ^2=12^2+12^2\\\Rightarrow XZ^2=144+144\\\Rightarrow XZ=\sqrt{144+144}\\\Rightarrow XZ=\sqrt{288}\\\Rightarrow XZ=12\sqrt{2}\ cm\)

So, the answer is Hypotenuse, XZ = \(12\sqrt{2}\ cm\).

The measure of the other diagonal line is 6.8 inches

A kite is a quadrilateral with two distinguishable consecutive sides. The area of a kite can be calculated by the multiplication of the two diagonal lines divided by 2.

Mathematically, we have:

\(\mathbf{A = \dfrac{pq}{2}}\)

Answer:

Step-by-step explanation:

The median in a stem-and-leaf diagram is the number that is repeated the most. In this case, the number 78 is repeated 4 times (7 | 8 8 8 8). No other number in the diagram is repeated as much or more than the number 78.

Do not make the mistake of writing the answer as 8 instead of 78.You also want to make sure you don't accidently count 68 which is repeated twice (by looking at the 8's at the end and thinking it's part of the all/rest of the 8's in the diagram).

Tο shift the graph tο the right, we can simply add a pοsitive cοnstant tο the x values οf each pοint befοre plοtting them. Fοr example, if we want tο shift the graph tο the right by 2 units.

The intersectiοn οf twο number lines creates a twο-dimensiοnal plane knοwn as a cοοrdinate plane. The x-axis, a hοrizοntal number line, and the y-axis, a vertical number line, are twο examples οf these number lines.

Tο graph the equatiοn 5x - 3y = 18 οn a cοοrdinate plane, we can fοllοw these steps:

1. Sοlve fοr y in terms οf x:

5x - 3y = 18

-3y = -5x + 18

y = (5/3)x - 6

2. Chοοse sοme values fοr x and use the equatiοn tο find the cοrrespοnding y values. Fοr example, we can chοοse x = 0, 3, and 6:

When x = 0: y = (5/3)(0) - 6 = -6

When x = 3: y = (5/3)(3) - 6 = -3

When x = 6: y = (5/3)(6) - 6 = 2

3. Plοt the pοints (0, -6), (3, -3), and (6, 2) οn the cοοrdinate plane.

Answer:

3 = 14 and 4 = 8

Step-by-step explanation:

The reason as to why this is, is because of the line going down the middle. If you were to open one of the lengths as a door starting from the middle line it would fit perfectly with the top one.

Since, the angle 3 measures 84 degrees (2(39) + 6), and angle 2 measures 57 degrees (2(39) + 6 - 27). Therefore, the measure of angle 2 is 57 degrees.

To solve this problem, we can use the fact that angles on a straight line add up to 180 degrees. Let's call the measure of angle 1 "x". Then, we know that the measure of angle 3 is 6 more than twice "x", or 2x + 6. We also know that the measure of angle 2 is 27 less than angle 3, or 2x + 6 - 27. Finally, we can set up an equation using the sum of the angles on the straight line, and solve for "x" to find the measure of angle 2.

Let's call the measure of angle 1 "x". Then, we know that the measure of angle 3 is 6 more than twice "x", or 2x + 6. We also know that the measure of angle 2 is 27 less than angle 3, or 2x + 6 - 27.

Using the fact that the three angles form a straight line, we can write the equation:

angle1 + angle2 + angle3 = 180

Substituting in the values we know, we get:

x + (2x + 6 - 27) + (2x + 6) = 180

Simplifying this equation, we get:

5x - 15 = 180

Adding 15 to both sides, we get:

5x = 195

Dividing both sides by 5, we get:

x = 39

Therefore, the measure of angle 1 is 39 degrees. Using the expressions we found for the other angles, we can find that angle 3 measures 84 degrees (2(39) + 6), and angle 2 measures 57 degrees (2(39) + 6 - 27). Therefore, the measure of angle 2 is 57 degrees.

Hey there! I'm happy to help!

In the quadratic formula, the discriminant is square rooted. In this formula you have a ± before this radical. If the discriminant is positive, the solution can be either subtracting or adding the number, so there are 2 real solutions.

If it is 0, subtracting or adding are the same, so there will be just one solution.

You cannot have a negative square root. It is impossible with real numbers, so there are no real solutions.

I hope that this helps! Have a wonderful day! :D

The zeroes based on nature of discriminant is described below.

We know that,

A quadratic equation is of the form ax + bx + c = 0,

Where a, b, and c are constants and x is the variable.

The discriminant of a quadratic equation is given by the expression,

⇒  b² - 4ac.

If the discriminant is positive (b² - 4ac > 0),

Then the quadratic equation has two real solutions.

This is because the quadratic formula, which gives the solutions of the quadratic equation, involves the square root of the discriminant.

Since the discriminant is positive, the square root is a real number, resulting in two distinct real solutions.

If the discriminant is negative (b² - 4ac < 0),

The square root of the discriminant is an imaginary number since it involves a negative integer's square root.

Given that the discriminant is a component of the quadratic formula,

if it is negative, the quadratic formula will include computing the square root of a negative integer, which is not a real number.

This is due to the fact that solving the quadratic equation requires obtaining the square root of the discriminant, and a negative square root is not a real integer.

In conclusion, there are no actual solutions to a quadratic equation with a negative discriminant since the solutions entail calculating the square root of a negative.

When the discriminant is zero,

it means that the quadratic equation has only one solution, which is a real number.

This is because the quadratic formula for finding the solutions of the quadratic equation reduces to a simpler formula when the discriminant is zero. Specifically,

The quadratic formula becomes,

x = -b/2a This formula gives us the only solution of the quadratic equation when the discriminant is zero.

Plugging in the given values, we get:

percentage = (6,500 / 4,800) x 100%

percentage = 1.35416666667 x 100%

percentage = 135.42%
