Question

1. luella is heating water at a constant rate as shown in the table. - let s represent the time, in seconds, that luella heats the water. - let t represent the temperature of the water, in degrees celsius. enter the temperature of the water, in degrees celsius, after 23 seconds

time in seconds (s)	0	5	10	15	20

Explanation:

Step1: Find temperature increase rate

Rate = $\frac{17-12}{5-0} = \frac{5}{5} = 1$ °C per second

Step2: Define linear temperature formula

$t = 12 + 1 \times s$

Step3: Calculate temp at 23 seconds

$t = 12 + 1 \times 23$

Answer:

35
