![\[\left | 4-3i \right |\]](/tpl/images/0015/0255/14bd1.png)
will be 5.
.
can be calculated as,![\[\left | a-bi \right |\]=\sqrt{a^{2}+b^{2} }](/tpl/images/0015/0255/4df14.png)
![\[\left | 4-3i \right |\]=\sqrt{4^{2}+3^{2} }\\\[\left | 4-3i \right |\]=\sqrt{16+9 }\\\[\left | 4-3i \right |\]=\sqrt{25}\\\[\left | 4-3i \right |\]=5](/tpl/images/0015/0255/7cd61.png)
, here a=4 and b= -3

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
