The best number to simplify a fraction is C Greatest common factor.

The greatest common factor is the highest number that can divide both the numerator and the denominator of the fraction without leaving a remainder.

To find the greatest common factor, list the prime factors of each number, take the common factors, and then multiply them.

For instance, the greatest common factor of 24 and 36 is 12, produced from the common factors of 3 and 4 (2 x 2) multiplied to get 12 (3 x 4).

Thus, it is easier to simplify a fraction using Option C than the other options.

Answer:

parallelogram, square, rectangle, rhombus

(all)

Step-by-step explanation:

A square is a shape that has four sides equal in length

the little dash-marks on multiple sides are to show that the two sides are of the same dimension/length.

So, if all four sides are marked as equivalent, this must be a square.

And, a parallelogram is a shape with two pairs of parallel sides, meaning that a square/this shape is a parallelogram

However, a square is also a rectangle, because it is a parallelogram with four 90-degrees (interior) angles [which is just a formal definition for what you know to be a rectangle].

AND a square is a rhombus because it has four sides of equal length

a square is a rectangle;  a rectangle is a parallelogram

a square is a rhombus;

a rhombus is a parallelogram; a square is a parallelogram

The height of the 10th bounce of the ball will be 0.6 feet.

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.

The nth term of the geometric sequence is given by

\(\sf T_n=ar^{n-1}\)

Where,

According to the given question.

During the first bounce, height of the ball from the ground, a = 4.5 feet

And, the each successive bounce is 73% of the previous bounce's height.

So,

During the second bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 10\)

\(=\dfrac{73}{100}(10)\)

\(\sf = 0.73 \times 10\)

\(\sf = 7.3 \ feet\)

During the third bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 7.3\)

\(=\dfrac{73}{100}(7.3)\)

\(\sf = 5.33 \ feet\)

Like this we will obtain a geometric sequence 7.3, 5.33, 3.11, 2.23,...

And the common ratio of the geometric sequence is 0.73

Therefore,

The sixth term of the geometric sequence is given by

\(\sf T_{10}=10(0.73)^{10-1\)

\(\sf T_{10}=10(0.73)^{9\)

\(\sf T_{10}=10(0.059)\)

\(\sf T_{10}=0.59\thickapprox0.6 \ feet\)

Hence, the height of the 10th bounce of the ball will be 0.6 feet.

Given

The representation on the unit circle is shown below

Going round the circle in the negative direction, we realize

Given that the box contains 46 red marbles, 58 white marbles, and 51 blue marbles, you know that the total number of marbles the box contains is:

In this case, let be A the event in which the randomly selected marble from the box is white, and B the event in which the randomly selected marble from the box is blue.

Since those events are independent, you can set up that the probability of randomly selecting a white marble or blue marble from the box is:

Knowing that there are 58 white marbles, you can determine that:

And knowing that there are 51 blue marbles, you can determine that:

Therefore:

Hence, the answer is:

The probability that a designer does not prefer blue is approximately 0.8775, or 87.75%.

To calculate the probability that a designer does not prefer blue, we need to consider the number of opinions that do not prefer blue and divide it by the total number of opinions.

The number of opinions that do not prefer blue is the sum of opinions for all other colors except blue:

Number of opinions not preferring blue = Number of opinions for red + Number of opinions for orange + Number of opinions for yellow + Number of opinions for green + Number of opinions for indigo + Number of opinions for violet

= 80 + 74 + 58 + 79 + 58 + 2

= 351

Total number of opinions = Number of opinions for red + Number of opinions for orange + Number of opinions for yellow + Number of opinions for green + Number of opinions for blue + Number of opinions for indigo + Number of opinions for violet

= 80 + 74 + 58 + 79 + 49 + 58 + 2

= 400

Therefore, the probability that a designer does not prefer blue is:

P(Not preferring blue) = Number of opinions not preferring blue / Total number of opinions

= 351 / 400

≈ 0.8775

The probability that a designer does not prefer blue is approximately 0.8775, or 87.75%.

The general solution to the differential equation y'' + 16y = 0 is y(x) = (c₁ + c₂) * cos(4x)

To solve the differential equation y'' + 16y = 0 using reduction of order, we'll assume a second solution of the form y₂(x) = u(x) * y₁(x), where y₁(x) is a known solution and u(x) is an unknown function.

Given y₁(x) = cos(4x), we'll differentiate it to find y₁'(x) and y₁''(x):

y₁'(x) = -4sin(4x)

y₁''(x) = -16cos(4x)

Now we substitute y₂(x) = u(x) * y₁(x) into the original differential equation:

y'' + 16y = 0

(-16cos(4x)) + 16(u(x) * cos(4x)) = 0

Simplifying the equation:

-16cos(4x) + 16u(x) * cos(4x) = 0

cos(4x)(-16 + 16u(x)) = 0

For this equation to hold for all values of x, we must have (-16 + 16u(x)) = 0.

Solving for u(x):

-16 + 16u(x) = 0

16u(x) = 16

u(x) = 1

Now we have the second solution:

y₂(x) = u(x) * y₁(x)

y₂(x) = 1 * cos(4x)

y₂(x) = cos(4x)

Therefore, the general solution to the differential equation y'' + 16y = 0 is:

y(x) = c₁ * y₁(x) + c₂ * y₂(x)

y(x) = c₁ * cos(4x) + c₂ * cos(4x)

y(x) = (c₁ + c₂) * cos(4x)

Where c₁ and c₂ are arbitrary constants.

The set A that will make the statement false is A is the set of whole numbers.

option B is the correct answer.

To make the statement "B ⊆ A" false, we need to choose a set A that does not contain all the elements of set B.

The given elements of set B include;

B = (-13, -9, -7, -3)

If we consider the first option;

A is the set of negative odd integers

= {negative odd integers} = {-13, -9, -7, -3}

So the elements in the set will not make the statement false.

Let's consider the second option

A is the set of whole numbers.

Whole numbers are positive numbers, since elements in set B are all negative numbers, we can conclude that set B is not a subset of whole numbers.
