How do you identify a function if you have a TABLE?​

Answers

Answer 1

Answer:

You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

What is comparison in mathematics?

Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.

Given are 80 marbles for $4.99 and 90 marbles for $5.99.

Using Unitary method -

80 marbles cost → $4.99

1 marble will cost → (4.99/80) = $0.062

90 marbles cost  → $5.99

1 marble will cost → (5.99/90) = $0.066

Clearly $0.062 < $0.066

So, 80 marbles for $4.99 is a better buy.

Therefore, 80 marbles for $4.99 is a better buy as compared with 90 marbles for $5.99

What are the solutions of this quadratic equation?
X^2 = 16x – 65

Answers

Answer:

x= 4.3125

Step-by-step explanation:

Answer:

x=4+7i and x=4-7i

Step-by-step explanation:

Rewrite the given quadratic equation by completing the square.

x^2-8x=-65

x^2-8x+16=-65+16

x^2-8x+16=-49

(x-4)^2=-49

Now, solve the equation by applying the square root property and isolating x.

(x-4)^2=-49

√(x-4)^2 = √-49

x-4=+7i

x=4+7i

So, the solutions to the given quadratic equation are x+4+7i and x=4-7i.

A ticket to see your favorite baseball team cost $43.32. The price decreases by $0.25 for every game loss during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 24 games. What is the price of a ticket after the team loses 24 games?

Answers

Answer:

$37.82

Step-by-step explanation:

Given that the cost of the ticket is

$43.32

and the price decrease is by $0.25

let the cost be C

and let the number of losses be L

the expression for the cost we be

C=43.32-0.25L

for the number of losses which is 22 we have

C=43.32-0.25(22)

C=43.32-5.5

C=37.82

Therefore the price after 22 losses is $37.82

Answers

Answer:

The students can make 70 pieces of ornament from the 5 pieces of Bristol board from the cupboard.

Step-by-step explanation:

Since each student takes 14 of a piece of Bristol board to make an ornament, and we have 5 pieces of Bristol board in the cupboard, this implies that we require 1 Bristol board makes 14 pieces of ornament. Therefore 5 pieces of Bristol Board will make 5 × 14 pieces of ornament = 70 pieces of ornament.

OA
12 inches
OB. 15 inches
OC 21 inches
OD. 40 inches

Answers

Answer:

Option B: 15 inches

Step-by-step explanation:

p=2w+2l so 12 (2*6) +2x= 42

42-12=30

30/2=15

The answer is:

15 inches

Explanation:

P = perimeter = 42

L = length = ?

W = width = 6

P rectangle = 2L + 2 W

Substitute into formula:

42 = 2L + 2 * 6

42 = 2L + 12

42 - 12 = 2L

30 = 2L

L = 30/2 = 15

L = 15 inches

What is inequality?

In mathematics, an inequality is a relationship that compares two numbers or other mathematical expressions unequally.[1] It is most often used to compare two numbers by their size. Several different notations are used to denote different types of inequality:

The notation a < b means that a is less than b.

Notation a > b means that a is greater than b.

In both cases, a is not equal to b. These relationships are known as strict inequalities,meaning that a is strictly less than or strictly greater than b. Equivalence is excluded.

Unlike strict inequalities, there are two types of inequalities that are not strict:

The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or equivalently at most b or not greater than b).

The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or equivalently at least b or not less than b).

A ratio that is not greater than can also be represented as a ≯ b, with the "greater than" symbol separated by a slash "not". The same is also true for no less than and a ≮ b.

The notation a ≠ b means that a is not equal to b; this difference is sometimes considered a form of strict inequality.It does not say that one is greater than the other; it does not even require that a and b be members of an ordered set.

Here given,[tex]2x < 10[/tex]

We want to find solution set of 2x < 10

Now,2x < 10

First we are dividing both side by 2 and get,

[tex] \frac{2x}{2} < \frac{10}{2} \\ x < 5[/tex]

Therefore,required solution is x < 5.

Goal-Setting, Expectancy, Reinforcement, and Equity Theory Goal-Setting, Expectancy, Reinforcement, and Equity Theories all serve Theory Y managers in understanding how employees can be motivated at work. Employees seek interesting and challenging work in a fair work environment that allows for autonomy. There should be a system to engage everyone in the organization in goal setting and implementation as well as an expectation that effort expended will result in a positive outcome and be balanced from one employee to another (given the same work). Managers can also find success in fairness and a reward system that all employees value.Goal-setting theory is based on the premise that employees are motivated when they are clear about the goals they are working toward. More importantly, they are more likely to engage to attain these goals if they collaborate with management in planning. Management by Objectives (MBO) is the process of discussion, review, and evaluation of goals between a manager and employee. Expectancy theory is based on the premise that the amount of effort employees exert on a specific task depends on their expectations of the outcome. Reinforcement theory states that individuals act to receive rewards and avoid punishment. A manager may attempt to surface good behaviors through rewards and extinguish poor behaviors through punishment. Equity theory zeros in on how employees' perceptions of fairness affect their willingness to perform. Roll over each employee name to read a scenario. Match the scenario with the respective theory on the left by dragging the employee name to the corresponding theory.1.
