Alessandra is raising turtles and must keep the air temperature in their enclosure at 23° C, with a relative error less than 4%. Write an absolute value inequality for
the actual temperature. Find the interval in which the actual temperature must lie.

Respuesta :

[tex]\\ \sf\longmapsto 23°C\pm 4\%\;of\:23=T[/tex]

[tex]\\ \sf\longmapsto 23°C\pm \dfrac{4}{100}(23)=T[/tex]

[tex]\\ \sf\longmapsto 23°C\pm 0.04(23)=T[/tex]

[tex]\\ \sf\longmapsto 23°C\pm 0.92=T[/tex]

T is the actual temperature
