Answer:
The temperature of the chemical solution after t hours is
Step-by-step explanation:
Given that the initial temperature of the chemical solution, .
The rate of decreasing temperature,
So, after t hours, the temperature of the chemical solution will decrease by .
So, the temperature of the chemical solution after t hours,
Hence, the temperature of the chemical solution after t hours is .
The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, using the points (0, 0) and (3, 12):
y - 0 = [(12 - 0)/(3 - 0)](x - 0)
y = 4x
The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.
