Solutions

Chapter 1.1, Problem 37E

(a)

To determine

To write: the statement “ x is positive” in terms of inequality.

Expert Solution

Answer to Problem 37E

  x>0

Explanation of Solution

Given information:

  x is positive

Calculation:

Consider the given statement.

  x is positive

Now, positive number is always greater than 0.

So, x>0 .

(b)

To determine

To write: the statement “ t is less than 4” in terms of inequality.

Expert Solution

Answer to Problem 37E

  t<4

Explanation of Solution

Given information:

  t is less than 4

Calculation:

Consider the given statement.

  t is less than 4

Now, less than sign is '<' .

So, t is less than 4, in terms of an inequality can be written as

  t<4 .

(c)

To determine

To write: the statement “ a is greater than or equal to π ” in terms of inequality.

Expert Solution

Answer to Problem 37E

  aπ

Explanation of Solution

Given information:

  a is greater than or equal to π .

Calculation:

Consider the given statement.

  a is greater than or equal to π

Now, greater than equal sign is '' .

So, a is greater than or equal to π , in terms of an inequality can be written as

  aπ .

(d)

To determine

To write: the statement “ x is greater than 5 and less than 13 ” in terms of inequality.

Expert Solution

Answer to Problem 37E

  5<x<13

Explanation of Solution

Given information:

  x is greater than 5 and less than 13 .

Calculation:

Consider the given statement.

  x is greater than 5 and less than 13

Now, greater than sign is '>' and less than symbol is '<' .

So, x is greater than 5 and less than 13 , in terms of an inequality can be written as

  5<x<13 .

(e)

To determine

To write: the statement “the distance between p and 3 is at most 5 ” in terms of inequality.

Expert Solution

Answer to Problem 37E

  |p3|5

Explanation of Solution

Given information:

The distance between p and 3 is at most 5 .

Calculation:

Consider the given statement.

The distance between p and 3 is at most 5 .

Distance between two points a and b can be written as

  d(a,b)=|ab|

Now, for the word “at most” the required symbol is '' .

So, the distance between p and 3 is at most 5 , in terms of an inequality can be written as

  d(p,3)5|p3|5 .
