Is The Relation A Function? If It Is A Function, State The Domain And Range. If Not, Circle Orhighlight

Answers

Answer 1

Answer:

Please check the explanation.

Step-by-step explanation:

Writing this relation in set notation using curly braces:

{(1, 3), (2, 5), (3, -1), (4, 0), (5, 6)}

The relation clearly indicates that each input is related to exactly one output. In other words, there is no repetition of 'x' values.

Hence, this relation is a function.

We know that the domain is the set of all x values.

Thus, the domain is: {1, 2, 3, 4, 5}

We know that the domain is the set of all y values.

Thus, the range is: {-1, 0, 3, 5, 6}

Brenda took her dog to the veterinarian for an exam. The doctor told Brenda her dog needed to lose weight. Her dog weighed 55 pounds during this visit. The doctor suggested that her dog 45 pounds by their next visit. What is this weight decrease represented as a percent?

Answers

Answer:

18%

Step-by-step explanation:

Step one;

given

initial weight = 55 pounds

final weight= 45 pounds

Step two:

Required

the % weight decrease

% decrease= initial-final/initial *100

% decrease= 55-45/55 *100

% decrease= 10/55 *100

% decrease= 0.18 *100

% decrease= 18%

Part B: A triangle has vertices A (-2, 3), B (0, 0), and C (1, 2). What are the coordinates of the vertices if the original triangle is dilated by a scale factor of 3 and then reflected over the x-axis?

Answers

Answer:

(-6,-9) , (0,0) and (3,-6)

Step-by-step explanation:

Here, we want to find new coordinates after dilating by 3 and reflecting over x-axis

By dilating by a factor of 3, we multiply each term by 3

We have the following;

A’(-6,9) B’(0,0) and C’ (3,6)

Now if we want to reflect the point (x,y) over x-axis, what we shall have is (x,-y)

So the vertices will be as follows;

(-6,-9) , (0,0) and (3,-6)

Complete the explicit formula for the sequence.

Answer:

  125%

Step-by-step explanation:

(9/4)X = (1 +5/4)X = (1 +1.25)X = X + 125%·X

Jack needs to increase X by 125% to get 9/4X.

_____

Example:

X = 100, 9/4X = 225

125%X = 125, so X + 125%X = 100 +125 = 225 . . . as required.

Find the percent of change:
From 64 feet to 48 feet

Answers

Answer:16

Step-by-step explanation:

Using this tool you can find the percent Decrease for any value. So, we think you reached us looking for answers to questions like:

1) What is the percentage Decrease from 64 to 48? 2) What is the absolute Decrease from 64 to 48. Or may be: What is the percent change from 64 to 48?

See the solution to these problems just after below.

How to calculate percent change - Step by Step

Percent increase or decrease measures percent changes between two values. Use this calculator when comparing an old value to a new value.

The Percent Calculator (Change) uses this formula:

% change = New Value - Old Value|Old Value|× 100%

Where |Old Value| represents the absolute value of the reference (this is made in order to work well with both positive and negative values of Old Value and New Value. Note that percent change and relative change mean the same thing. It can be a percent increase or a percent decrease depending on the new and the old values. If the new value is greater than the old value, the result will be positive and we will have a increase. On the other hand, if the new value is smaller than old value, the result will be negative and we will have a we have a decrease. The old value, as a reference, may be: a theoretical, the actual, the correct, an accepted, an optimal, the starting, and so on. See more about percent percent change here.

Here are the solutions to the questions stated above:

1) What is the percentage decrease from 64 to 48?

Use the above formula to find the percent change. So, replacing the given values, we have

Percent change = 48 - 6464 x 100 = -25 % (decrease)

Where: 64 is the old value and 48 is the new value. In this case we have a % of decrease because the new value is smaller than the old value.

2) What is the absolute Decrease from 64 to 48?

This problem is not about percent or relative change, but about absolute change. Its solution is very simple:

Absolute change, or

change = new value - old value

= 48 - 64 = -16 (decrease)

Answer: -25%

Step-by-step explanation:A change from 64 to 48 represents a negative change (decrease) of -25%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = New - Old

|Old|

x 100%

Percent change = 48 - 64

|64|

x 100 = -16

64

x 100 = -25 % (decrease)

Where: 64 is the old value and 48 is the new value. In this case we have a negative change (decrease) of -25 percent because the new value is smaller than the old value.
