Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

f(4) = 82.944

Step-by-step explanation:

f(x)=a(b)^x

a is the initial value and b is 1 + growth rate in decimal form

a = 40 and

b = 1 +.2 = 1.2

f(x) = 40 (1.2)^x

f(4) means let x =4

f(4) = 40 (1.2)^4

f(4) = 82.944

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
