The normal body temperature of a camel is 37 degrees Celsius the temperature varies by up to three degrees C throughout the day. Write and solve an absolute value inequality that represents the range of normal body temperatures in degrees celsius of a camera throughout the day where to represents the normal body temperature?

Respuesta :

The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3     AND  ( - t - 37 ) ≤ 3
t ≤ 3 + 37               - t + 37 ≤ 3
t ≤ 40                     - t ≤ 3 - 37
                              - t ≤ - 34   / * ( - 1 )
                                t ≥ 34
Answer t ∈ [  34°C,  40° C ].

The range of normal body temperatures in degrees celsius of a camel throughout the day when [tex]t\in[34^\circ \rm{C},\; 40^\circ \rm{C}][/tex].

Explanation:

Given: The normal body temperature of a camel is [tex]37[/tex] degrees celsius the temperature varies by up to three degrees celsius throughout the day.

Let the normal temperature of camel be [tex]t_{o}[/tex].

According to the question,

Absolute temperature of camel's body throughout day is calculated as

[tex]\\\vert {t-t_{o}} \rvert}\leq3\\\\\vert {t-37} \rvert}\leq3\\[/tex]

Now, solving the inequality:

    [tex](t-37)\leq3[/tex]                  and             [tex]-(t-37)\leq3[/tex]

[tex]t-37+37 \leq {37+3}[/tex]          and              [tex]{-t+37}\leq3[/tex]

               [tex]t\leq40[/tex]                             [tex]-t+37-37\leq3-37[/tex]

                                                                     [tex]-t\leq-34\\[/tex]

                                                                       [tex]{t\geq34}[/tex]

Here, range of temperature is [tex][34^\circ \rm{C},\; 40^\circ \rm{C}][/tex]

Therefore, the range of normal body temperatures in degrees celsius of a camel throughout the day when [tex]t\in[34^\circ \rm{C},\; 40^\circ \rm{C}][/tex].
