Answer:
y = 0.2(0.5)^x
Step-by-step explanation:
Exponential function are of the form
y = ab^x
----------------------
To find "a" plug in x = 0 y = 0.2
0.2 = a(0.2)^0
0.2 = a
-------------------------
To find "b" plug in another point and a = 0.2
using x = 2, b = 0.05
0.05 = 0.2b^2
Divide both sides by 0.20
.25 = b^2
Take the square root of both sides
0.5 = b
-----------------------------
With a = 0.2 and b = 0.5 the equation becomes
y = 0.2(0.5)^x
Consider the given equation:
Cross multiplying in the given equation, we get
Applying distributive property which states 
, we get
Adding '4' on both the sides, we get
Subtracting '10n' from both the sides of the equation, we get
Dividing by '-8' in both the sides of the equation, we get
Therefore, the value of 'n' is -1.
