According to the equation for the maximum speed, it is found that the height at the top of the swing of the rider is of 0.8 m.

As stated in the problem, it is given by:

v = 2gh.

In which:

In this problem, the parameters are g = 9.8, v = 15. Hence we can solve for h to find the height.

v = 2gh

2 x 9.8h = 15

19.6h = 15

h = 15/19.6

h = 0.8.

The height at the top of the swing of the rider is of 0.8 m.

Answer:

  x ∈ {-4, 0, 2}

Step-by-step explanation:

You want the solutions to the cubic 2x³ +4x² -16x = 0.

We observe that x and 2 are factors of all terms, so this can be written ...

  2x(x² +2x -8) = 0

The quadratic will have binomial factors with constants that are factors of -8 that have a sum of 2.

  2x(x +4)(x -2) = 0

Solutions are the values of x that make the factors zero:

  x = 0

  x +4 = 0   ⇒   x = -4

  x -2 = 0   ⇒   x = 2

The solutions are x = -4, 0, 2.

a. The measure of angle 7 is 47°. It is is a vertical angle to angle 5

b. If the measure of ∠6 is represented by (2x - 5), the equation used to solve for x is 42 + 2x = 180

c. The value of x is 69

Vertically opposite angles are defined as those angles that are opposite one another at a vertex and are formed by the intersection of two straight lines.

Vertical opposite angles are known to be congruent.

From the information given, we have;

a. ∠5 ≅ ∠7, they are vertical angles

Therefore, angles 5 and 7 are congruent to each other.

∠7 = 47°

b. Suppose ∠6 = 2x - 5

To determine the value of x, we have

∠5 + ∠6 = 180

Then, we have the equation as;

47 + 2x - 5 = 180

collect the like terns

2x = 180 - 42

2x = 138

Divide both sides by 2

x = 138 / 2

x = 69

The least common denominator (LCD) for the rational expressions A and B is (x - 2)(x + 2).

To find the least common denominator (LCD) of rational expressions, you can follow these steps:

Identify the denominators of the rational expressions involved.

Factorize each denominator completely.

Identify the common factors among all the denominators. Include each factor the maximum number of times it appears in any of the denominators.

Multiply together all the common factors identified in step 3. This product represents the LCD.

Simplify the LCD if possible by canceling out any common factors that appear in both the numerator and denominator of any rational expression.

Here's an example to illustrate the process:

Consider the rational expressions:

A = (3x) / (x² - 4)

B = (2) / (x - 2)

Step 1: Identify the denominators

Denominator of A: x² - 4

Denominator of B: x - 2

Step 2: Factorize each denominator

x² - 4 = (x - 2)(x + 2)

Step 3: Identify the common factors

The common factor is (x - 2).

Step 4: Multiply together the common factors

LCD = (x - 2)(x + 2)

Step 5: Simplify the LCD

In this case, the LCD is already in its simplest form.

So, the least common denominator (LCD) for the rational expressions A and B is (x - 2)(x + 2).

a)  JKLM is a parallelogram

b) JKLM is not  a rectangle

c) JKLM is not  a rhombus

What is rectangle?

A rectangle is a type of quadrilateral with parallel sides equal to each other and four equal 90-degree vertices. Because of this, it is also known as an equiangular quadrilateral. Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.

In the figure,

15x= 13x+12

=> 15x-13x=12

=> 2x=12

=> x=12/2 = 6

The value of x is 6

The angle at the intersection of diagonal is 15x=15*6 =90 degrees

a)A square is a quadrilateral with two pairs of parallel sides, four right angles, and four congruent sides.

Quadrilaterals called parallelograms have two pairs of parallel sides. All squares are parallelograms because squares must have quadrilaterals with two pairs of parallel sides.

So, JKLM is a parallelogram

b)  A square and a rectangle vary significantly in that a square has equal lengths on all sides while a rectangle has equal lengths on its opposite sides.

So, JKLM is not  a rectangle

c) A rhombus only has its opposite angles identical, unlike a square, which has all of its angles at 90 degrees.

So, JKLM is not  a  rhombus

Answer:  " Yes; Kim is  correct."

Explanation:  [refer to the end of this "answer"].

Note: Any "triangle" has 3 sides and 3 angles.

An isosceles triangle has 2 (angles) with the exact same measurements.

We are given the following information:

We have an isosceles angle:
 with one of the angles = 48°
 _______
Does this mean that one of the angles must be:  66 ° ?

If so; then:  either:
       48 + 66 + 48 = 180 ?
or:   48 + 66 + 66 = 180 ?

1)  First: Start with 48 + 66 + 48 ≟ 180 ?

   (48 + 66 + 48) ≟ 180 ?   ;  162 ≟ 180?  No; " 162 < 180 " .

2) Second: Try:  "48 + 66 + 66 = 180 " .

   (48 + 66 + 66) ≟ 180 ? ;  180 ≟ 180 ? ; Yes! "180 = 180".
_______
So:  Kim is correct; because isosceles triangles must have angles with 2 (two) equal measurements.  Note that all triangles have angles that add up to 180° .  
So:  As shown above:
    If one angle of the triangle is 48°; then: **each** of the other angle measurements must be 66°.
  So:  Yes; Kim is correct when he says that one of the other angles must be 66°.
   (48 + 66 + 48) ≟ 180 ?   ;  162 ≟. 180?  No; " 162 < 180 " .

Applying the, Intersecting Chords Theorem, the value of x is calculated as: x = 16.

The Intersecting Chords Theorem is a geometric principle that states that when two chords intersect within a circle, the product of the lengths of the segments of one chord is equal to the product of the lengths of the segments of the other chord.

Thus, we would apply this theorem to find the value of x in the image given as explained below:

(x - 6)(8) = (x)(5)

8x - 48 = 5x

8x - 5x = 48

3x = 48

Divide both sides by 3

3x/3 = 48/3

x = 16

The probability that a student scores between 450 and 600 on the SAT math section is approximately 0.4147 or 41.47%.

To find the probability that a student scores between 450 and 600 on the SAT math section, we need to use the properties of the normal distribution. We know that the mean is 511 and the standard deviation is 110.

First, we need to standardize the values of 450 and 600 using the formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

For 450:

z = (450 - 511) / 110 = -0.55

For 600:

z = (600 - 511) / 110 = 0.81

Next, we need to find the area under the normal curve between these two standardized values. We can use a table or a calculator to find that the area between z = -0.55 and z = 0.81 is approximately 0.4147.

Only one singlet is expected in the 1H NMR spectrum of 2,2,4,4-tetramethylpentane. So, correct option is A.

In the 1H NMR spectrum, the number of singlets corresponds to the number of unique hydrogen environments in the molecule. Each unique hydrogen environment, where the hydrogens are chemically equivalent, will produce a singlet peak.

In 2,2,4,4-tetramethylpentane, all the carbons are identical, and each carbon is bonded to three hydrogen atoms. The four methyl groups (-CH3) are also chemically equivalent to each other. Therefore, all the hydrogens in this molecule are in equivalent environments, and there are no differences between them.

Since all the hydrogens are chemically equivalent, they will produce a single peak in the 1H NMR spectrum. This single peak is called a singlet.

Hence, the correct answer is option a, as only one singlet is expected in the 1H NMR spectrum of 2,2,4,4-tetramethylpentane.

One of the four operations used in mathematics, along with addition, multiplication, and division, is subtraction.

Removal of items from a collection is represented by the operation of subtraction.

For instance, in the following image, there are 5 2 peaches, which means that 5 peaches have had 2 removed, leaving a total of 3 peaches.

So, we have:

(x+7) and (3x+4)

We have to subtract as:

The diameter of a circle is determined by multiplying the radius by 2. In this case, if the radius of a circle is 2 inches, the diameter would be 4 inches.

The diameter of a circle is a straight line segment that passes through the center of the circle and connects two points on the circle's circumference. It is always twice the length of the radius. To determine the diameter, we can use the formula diameter = 2 * radius.

Given that the radius of the circle is 2 inches, we can substitute this value into the formula: diameter = 2 * 2 inches = 4 inches. Therefore, if the radius of a circle is 2 inches, the diameter of the circle would be 4 inches. This relationship holds true for any circle, where the diameter is always twice the length of the radius.
