In a lab, the temperature of various chemical reactions is changing by a fixed number of degrees per minute. Write a numeric expression that describes each of the following if all times are on the same day.
a. The temperature at 8:00 P.M. is 32°C. If it drops 1°C per minute, what will the temperature be at 8:30 P.M.?
b. The temperature at 8:20 P.M is 0°C. If it has dropped 2°C per minute, what was the temperature at 7:55 P.M.?
c. The temperature at 8:00 P.M. is -20°C. If it has dropped 2°C per minute, what was the temperature at 7:30 P.M.?
d. The temperature at 8:00 P.M. is 25°C. If it has been increasing every minute by 2°C, what was the temperature at 7:40 P.M.?

- Please refer belowarrow_forwardHi, can you guys help me with this? Thank you! Can you guys help me calculate again the Term GPA, Combined GPA, Cumulative GPA, Transfer GPA & Combined Cumulative GPA section? It's just not right right now. Here's the transfer totals point that I want to provide just in case you guys may ask where I get these from:arrow_forwardUse undetermined coefficients to find the particular solution to y"-3y+2y=4e3 Y(t) =arrow_forward
