We know that the line is tangent at the point (2,8)
The derivative of the function at x=2 is
So, the tangent line passes through the point (2,8) and has slope 2. The equation is
This line crosses the x axis where y=0:
Answer: I = 1500 t
Where, I = interest, t = time(in years)
Step-by-step explanation:
Here, the principal amount, P = 50000,
Annual rate of interest, r = 3 %
Let the total interest after t years is I,
So, by the simple interest formula,
Since, In the above equation,
The interest and time are directly proportional to each other,
Hence, the above equation is the direct proportion equation that relates interests and years.
