5, it says that the range is 5 so you count five across the chart from the first point of data
Answer:
9.33%
Step-by-step explanation:
Step one:
given
Principal= $10,000
Final amount = $150,000
time = 50-21= 29 years
Required
The rate
Step two:
to solve for the rate we can apply the formula for rate as
r = ln(A/P) /t
r= ln(150000/10000)/29
r= ln(15)/29
r=2.7080502011/29
r=0.0933
r= 0.0933*100
r= 9.33%
Answer:

And 
Step-by-step explanation:
For this case we assume that for the first square we have the following dimensions:

And we know that:

And the area for the second square would be:

And we know that the sum of areas is 65 so then we have this:

And replacing we got:


We can divide the last expression by 2 and we got:

And we can factorize the last expression like this:

And we have two solutions for
and we got:

Since the length can't be negative we have this:

And
