A sequence is a grouping of "terms," or integers. Term examples are 2, 5, and 8. Some sequences can be extended indefinitely by taking advantage of a specific pattern that they exhibit. Use the sequence 2, 5, 8, and then add 3 to make it longer. Formulas exist that show where to seek for words in a sequence. A sequence (or event) in mathematics is a group of things that are arranged in some way. In that it has components (also known as elements or words), it is similar to a set. The length of the sequence is the set of all, possibly infinite, ordered items. the action of arranging two or more things in a sensible sequence.

Evidence is utilised to back up a claim or argument in a direct proof. A direct proof's objective is to connect known facts or presumptions logically to the desired conclusion in order to show that a certain assertion is true. Direct proofs sometimes take the form of a series of logical stages that are combined to get the desired result.

A counterexample, on the other hand, is a solitary instance that refutes a claim or argument. A counterexample presents a particular situation in which a claim is wrong in order to demonstrate that the claim is not always true. In order to find holes in a mathematical proof or the boundaries of a theory or hypothesis, counterexamples might be helpful.

The distance from point C to A that is AC = 7.5 cm and CB = 10.5 cm.

While distance and displacement appear to have the same meaning, they actually have very different definitions and implications. Displacement is the measurement of "how far an object is out of place," whereas distance refers to "how much ground an object has covered during its motion."

Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

Let us suppose the distance between C to A = x.

Now, for C to B we have = 3 + x

Given, AB = 18

Thus,

AC + CB = AB

x + (x + 3) = 18

2x + 3 = 18

2x = 15

x = 7.5

Now, CB = 3 + x = 3 + 7.5 = 10.5

Hence, the distance from C to A that is AC = 7.5 cm and CB = 10.5 cm.

Answer: -13/17

Step-by-step explanation: To find the slope of the line that passes through the points (-9, 7) and (8, -6), you can use the slope formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (-9, 7) and (x2, y2) = (8, -6)

Substituting the values in the formula, we get:

slope = (-6 - 7) / (8 - (-9))

slope = -13 / 17

Therefore, the slope of the line that passes through the points (-9, 7) and (8, -6) is -13/17.

Answer:

If 45% of the fruit on a table are apples, then 55% of the fruit are oranges (since the total percentage must add up to 100%).

The probability of selecting a piece of fruit that is not an apple is equal to the percentage of oranges on the table, which is 55%.

Therefore, the probability of selecting a piece of fruit that is not an apple is 55%.

Answer:

Let the cost of one apple pie be A and the cost of one blackberry pie be B.

From the first statement, we can write the equation:

SA + 4B = 8140 ----(1)

From the second statement, we can write the equation:

4*B = 152

Solving for B:

B = 38

Substituting B in equation (1) and solving for A:

SA + 438 = 8140

S*A = 8008

A = 8008/S

We do not have enough information to find the value of S or A individually, but we can find the relationship between them:

A/B = (8008/S)/38 = 211/S

Therefore, the cost of one apple pie is 211 times the cost of one blackberry pie.

The inequality is graphed on the number line is

Inequality can be graphed on a number line by shading the appropriate region of the number line.

To graph an inequality x > -7, follow these steps:

Plot the critical points on the number line. The critical points are the values of x that make the inequality true with an equal sign. For example, to graph the inequality x > -7, we plot the critical point x = -7 on the number line.

Determine the direction of the shading or line. If the inequality is "greater than" or "greater than or equal to," shade to the right of the critical point..

If the inequality includes "or equal to," use a closed circle at the critical point. If the inequality does not include "or equal to," use an open circle at the critical point.

An angle is a geometric figure formed by two rays or line segments that share a common endpoint, known as the vertex. It is used to measure the amount of rotation between the two rays or line segments.

A radian is a unit of measure for angles, where the measure of the central angle is equal to the length of the corresponding arc on the unit circle. It is equal to approximately 57.3 degrees.

According to thw given information:

The table displays measures of angles in radians and degrees. Radians are a unit of measurement for angles, and they relate the length of the arc of a circle to the radius of that circle. One radian is equivalent to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle. Pi radians, or 180 degrees, represent a straight angle.

In the table, the first angle measure in radians is given as 9√5, which is an exact measure. The second angle measure in radians is given as 3π/4, which represents a quarter of the circumference of the circle, and is equal to 45 degrees. The first angle measure in degrees is given as 20°, which is the equivalent of π/9 radians, and the second angle measure in degrees is given as 275°, which is equivalent to 55π/36 radians.

Knowing how to convert between radians and degrees is important in many mathematical calculations, especially those involving trigonometry. Understanding the relationship between these units of measure can help to solve problems in many areas of mathematics and science.

Step-by-step explanation:

x^2-4x=32

Subtract from both sides:

x^2-4x-32=32-32

Simplify the expression

x^2-4x-32=0

To find the coefficients, use the standard form of a quadratic equation:

ax^2+bx+c=0

x^2-4x-32=0

a coefficient =1

b coefficient =-4

c coefficient =-32

Find the factors which product equals to coefficient a multiplied by coefficient c:

a coefficient ∙ c coefficient = 1 ∙ -32 = -32

List the factors of -32:

1, 2, 4, 8, 16, 32

Because the product of coefficient a and coefficient c equals a negative number (-32) one factor needs to be positive and the other one negative.

From the list of factors, find a pair which sum equals to the b coefficient.

b coefficient = -4

This pair doesn't work.

1*-32=-32

2*-16=-32

2-16=-14

Found it - this pair does the trick:

4*-8=-32

4-8=-4

The product of 4 and -8 equals to coefficient a(1) multiplied by coefficient c (-32) and their sum equals to coefficient b (-4).

Determining the highest point of value for a particular solution relies heavily on the type of problem which needs to be resolved.

The polynomial function with fifth degree and given zeroes is 4x⁵ - 20x⁴ + 64x³ + 324x² - 432x.

The maximum power of the variable in a polynomial function is its degree. For instance, since 2 is the largest power of x, the polynomial function f(x) = 3x2 + 2x + 1 has a degree of 2. We only take into account the degree of the term with the highest power of x when a polynomial function comprises many terms. A polynomial with no x terms is a constant function, and thus has degree zero.

To determine the polynomial, we determine the zeroes.
