If infinity n = 1 an = s, infinity n = 1 bn = t, then infinity n = 1 an + bn = s + t. if infinity n = 1 an = s, alpha c, then infinity n = 1 alpha an = alpha s.

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
