What is the name of the rule that helps calculate the doubling time of something modeling exponential behavior? For what range of interest rates is this rule accurate to approximately 1%? How many years would it take an investment to double if its value increased at 72% annually (use the rule from above)?

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
