Solutions

Chapter 1.1, Problem 35E

(a)

To determine

To state: whether the inequality π>3 is true or false.

Expert Solution

Answer to Problem 35E

  π>3 is false.

Explanation of Solution

Given information:

An inequality as π>3 .

Formula used:

For two numbers a and b

  a<b if a>b

Calculation:

Consider the given inequality.

  π>3

Now, it is known that π>3 as π=3.14...

Multiply both sides by (1) .

  π(1)>3(1)π<3

Hence, the inequality π>3 is false.

(b)

To determine

To state: whether the inequality 89 is true or false.

Expert Solution

Answer to Problem 35E

  89 is false.

Explanation of Solution

Given information:

An inequality as 89 .

Formula used:

For two numbers a and b

  a>b if the digit after decimal places of a is numerically greater than digits after decimal place of b.

Calculation:

Consider the given inequality.

  89

It is obvious that 9 is always strictly greater than 8.

As on number line 9 is place at the right side of 8.

Hence, the inequality 89 is false.
