F(x)=x 3−9xf, left parenthesis, x, right parenthesis, equals, x, cubed, minus, 9, x What is the average rate of change of f over the interval [1,6] [1,6]open bracket, 1, comma, 6, close bracket?

The average rate of change of is 34

Step-by-step explanation:

The formula for average rate of change is given as,  

Given that

The lies between interval 1 and 6. So a = 1 and b = 6.  

Substituting the values in the formula,  

Now to calculate and .

To calculate

To calculate

Substituting the values in the formula,  

it’s supposed to be -4+45=41

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
