So we are given:
where
.
Divide both sides by 1600:
Simplify:
Take the 6th root of both sides:
Subtract 1 on both sides:
So the exact solution is
Most likely we are asked to round to a certain place value.
I'm going to put my value for r into my calculator.
r=0.062350864
Rounding to nearest hundredths gives us r=0.06.
Answer:
Step-by-step explanation:
Given that A is a square matrix and A is idempotent
Consider I-A
i)
It follows that I-A is also idempotent
ii) Consider the matrix 2A-I
So it follows that 2A-I matrix is its own inverse.
Use x as the base variable. All others as x+(extra amount).
