13,18,23 are in arithmetic progression

The formula for the nth term of an AP is, Tn = a + (n - 1)d, where: 'a' is the first term of the AP and; 'd' is the common difference of the AP.

here a=13, d=18-13=5

Tn = a + (n - 1)d = 13+(n-1)5 = 13+5n-5 = 5n+8

Tn = 5n+8

The correct equation of the circle is the first option which is

(x - 5)² + (y + 2)² = 9

What is a circle?

A circle is a collection of all points in a plane that is uniformly distanced from a fixed point. The fixed point is referred to as the circle's centre. The radius of a circle is the separation between the centre and any point along its circumference.

The general equation of the circle is

(x-h)² + (y-k)² = r²

where r = radius of the circle

          (h,k) = centre of the circle

Given,

      radius r = 3

    centre = (h,k) =  (5,-2)

According to the above equation,

(x-5)² + (y-(-2))² = 3²

(x-5)² + (y+2)² = 9

Therefore the correct equation of the circle is the first option.

The triangle with given vertices is not an isosceles triangle.

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].

Let a triangle with vertices be A(-1 ,7), B(5, 5) and C(-2 ,1).

Using the coordinates A(-1, 7) and B(5, 5), we get

AB =√(5-7)²+(5+1)²

AB=√40

AB=2√10 units

Using the coordinates B(5, 5) and C(-2 ,1) we get

BC=√(-2-5)²+(1-5)²

BC=√65 units

Using the coordinates C(-2 ,1) and A(-1 ,7) we get

Answer:

-2.5

Step-by-step explanation:

We can start by isolating h on one side of the equation:

4x + 5 = h(-2x + 5)

Divide both sides by -2x + 5:

(4x + 5) / (-2x + 5) = h

Now, since the equation has only one solution, the value of h must be well-defined for all values of x except those that would make the denominator equal to zero. This happens when -2x + 5 = 0, or when x = (5 - 5) / (-2) = -2.5.

So, the value of h cannot be determined when x = -2.5. This means that the value of h cannot be equal to -2.5.

Answer:

Why do you need to set up a graph for this equation?

Step-by-step explanation:

∠LJK = 37° and ∠KLJ = 69º. So, ∠JKH = 16°. This can be solved by using the concept of triangle.

Correct option: B

When two beams or straight lines intersect at one of their ends, an angle is created. The vertices of such an angles is the location where two points come together. The word angle is taken from the Latin word angulus, which means "corner."

Depending on the measurement, there are many angles in geometry. Basic angles are identified by their names: acute, obtuse, right, straight, reflex, and complete rotation.

ΔJKL consist of 3 angles: ∠LJK, ∠KLJ and ∠JKL

We are given the measures of ∠LJK and ∠KLJ

In order to find ∠JKH we must find the missing angle in the triangle

Remember that angles in a triangle add up to equal 180

If we are given two angles we can find the missing angle by subtracting the measures of the known angles from 180

so ∠JKL = 180° - 37° - 69°

180° - 37° - 69° = 74°

Hence, ∠JKL = 74°

Now to find ∠JKH:

Angles ∠K, ∠JKH and ∠JKL appear to be formed on a straight line

Angles formed on a straight line add up to equal to 180°

So, ∠K + ∠JKH  + ∠JKL = 180°

∠K is a right angle, indicated by the little square.

Right angles have a measure of 90° so ∠K = 90°

We have also calculated the measure of ∠JKH = ( 74° )

That being said we plug in the given values into the equation created earlier and solve for ∠mJKH

We would have 90° + ∠JKH + 74° = 180°

For calculation ∠JKH:

90° + 74° = 164°

now we have 164° + ∠JKH = 180°

or, ∠JKH = 16°

Hence the answer is B

The sample space of an experiment is the set of all possible outcomes of the experiment. In the experiment of rolling a six-faced dice, the sample space is the set of all possible values that the dice can show when it is rolled.

Since a dice has six faces, each with a distinct number (1, 2, 3, 4, 5, or 6), the sample space of the experiment of rolling a six-faced dice is {1, 2, 3, 4, 5, 6}. This means that any time the dice is rolled, it can only show one of these six values.

If -8x + 2y = -10 and 7x + 6y = -3 are true equations what would be the value of 15x + 4y is Cross out the common factor: 7.

Verify your math to ensure that the values on either side of the equals sign are the same in order to create a genuine equation. To create a genuine equation, ensure sure the numbers on both sides of the "=" symbol are equal. For instance, the equation 9 = 9 is real. The equation 5 + 4 = 9 is accurate. The formula 6 + 3 = 9 is accurate.

Multiplying both side of a equation by a coefficient:{3(-8x + 2y) = -10 × 3, 7x + 6y = -3}

apply the distributive property {-24x + 6y = -30, 7x +6y -3}

Subtract the two equations: -24x + 6y - (7x +6y) = -30 - (-3)

Remove parentheses: -24x + 6y - 7x - 6y = -27

Cancel one variable : -24x - 7x = -27

Solve the equation: x = 27/31

Substitute into one of the equations: 7 × 27/31 + 6y = -3

Solve the equation: y = -47/31

The solution of the system is {x = 27/31, y = -47/31}

Substitute { x = 27/31 , y = -47/31  into 15x + 4y :: 15 × 27/31 + 4 × (-47/31)

The percentage of a circle's circumference is 18.17%.

We have,

To determine the percentage of a circle's circumference cut off by an angle, we need to calculate the fraction of the total circumference represented by the given angle and then convert it to a percentage.

The total circumference of a circle is 360 degrees or 2π radians.

First, we convert the angle measure of 31.9 degrees to radians:

31.9 degrees = 31.9 x (π/180) radians

Next, we add the given angle measure of 1.5 radians to the converted value:

31.9 x (π/180) + 1.5 radians

To calculate the fraction of the circumference, we divide the sum of the angles by the total angle of a circle (2π radians):

(31.9 x (π/180) + 1.5) / (2π)

To express it as a percentage, we multiply the fraction by 100:

[(31.9 x (π/180) + 1.5) / (2π)] x 100

Evaluating this expression will give us the final value, which represents the percentage of a circle's circumference cut off by the given angle.

Performing the calculations:

[(31.9 x (π/180) + 1.5) / (2π)] x 100 ≈ 18.17%

An angle with a measure of 31.9 degrees plus 1.5 radians cuts off approximately 23.3% of a circle's circumference.

To determine the percentage of a circle's circumference cut off by an angle, we need to find the ratio of the angle's measure to the total angle of a circle (360 degrees or 2π radians) and then multiply it by 100 to express it as a percentage.

First, let's convert the angle measure of 31.9 degrees to radians:

1 degree = π/180 radians

So, 31.9 degrees = (31.9 × π) / 180 radians

Now, let's add the angle in radians to the converted value:

31.9 degrees + 1.5 radians = (31.9 × π) / 180 + 1.5 radians

Next, we calculate the ratio of the angle to the total angle of a circle:

Angle ratio = (31.9 × π) / 180 + 1.5 radians / 2π radians

Finally, we multiply the ratio by 100 to obtain the percentage:

Percentage = Angle ratio × 100

Let's calculate it:

Angle ratio = ((31.9 × π) / 180 + 1.5) / (2π) ≈ 0.233

Percentage = 0.233 × 100 ≈ 23.3%

Therefore, an angle with a measure of 31.9 degrees plus 1.5 radians cuts off approximately 23.3% of a circle's circumference.

The percent error of the measurement, to the nearest tenth of a percent, is 4.54%

Percent error of the measurement:

Percent error is the difference between the estimated value and the actual value in comparison to the actual value and is expressed as a percentage.

In other words, the percent error is the relative error multiplied by 100.

The formula for percent error is:

PE = (|Estimated value-Actual value|/ Actual value) × 100

Here,

T = True or Actual value

E = Estimated value

Estimated length of a line = 2.1 inches

The actual length of the line = 2.2 inches

Error = 2.2-2.1=0.1inches

The volume of the solid generated when r is rotated about the line y=4 is 512/15π

In math the term called volume in math is defined as a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Here we know that let r be the region bounded by the parabola y=x² and the line y=4.

Then the volume of the solid generated when r is rotated about the line y=4 is calculated by using the formula,

=> V = π ∫ᵇₐ [(h - f(x))]² dx

Here we have to apply the values on it, then we get,

=> V = π ∫₋₂² [(4 - x²)]² dx

By Using symmetry this can be written as,

=> V = 2π ∫₋₂² [16 - 8x² + x⁴] dx

When Solving the integral, then we get,

=> V = 2π (16x - 8/3x³ + 1/5x⁵)²₀

Here by Applying the fundamental theorem of calculus, then we get,

=> V = 2π (16(2) - 8/3(2)³ + 1/5(2)⁵) - 2π (16(0) - 8/3(0)³ + 1/5(0)⁵)
