20/8 = 10/4 = 5/2 = 2 1/2
Answer:
Step-by-step explanation:
The general formula for a horizontal hyperbola :
Given: a = 1 we know a² = 1 ,and that c = 9 so we know c² = 9² = 81
We also know that the relation between a, b, c for a hyperbola is c²= a²+b²
c²= a²+b², substitute what we know
81 = 1 +b², subtract 1 from both sides of the equation
80 = b²
The equation of our hyperbola is:
or

Answer: After 18.05 minutes, the temperature of steel becomes 100 degrees.
Step-by-step explanation:
Since we have given that
Initial temperature = 2500
At t = 0,
we get that
After 2 minutes, the temperature of the steel is 1500 degrees.
so, it becomes,
So, We need to find the number of minutes when the temperature of steel would be 100 degrees.
So, it becomes,
Hence, after 18.05 minutes, the temperature of steel becomes 100 degrees.
