we know that
The formula to calculate the slope between two points is equal to
substitutes the values
Step
Find the equation of the line
we know that
the equation of the line in the point-slope form is
we have
substitute in the equation
--------> this is the linear equation that model the relationship between height h of the candle and time t
Step
Find the height for hours
substitute the value of x in the linear equation
The height of the candle will be after
Answer: 9/25
Step-by-step explanation:
Use a calculator.
1 2/3=5/3.
5/3 / 3/5=3/5*3/5=9/25.
