Answer:
Step-by-step explanation:
we know that
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
so
where
a, b and c are the length sides of triangle
s is the semi-perimeter of triangle
we have
<em>Find the semi-perimeter s
</em>
s=
Find the area of triangle
simplify
It will be 11v
If you rearrange it to 12v- v
Then it’ll look like 12v- 1v
Which equals 11v
Treat it as a fraction where it must stay equal
6/54
with fractions, you can do anything as long as you do it so top and bottom
so 6/54=1/9=2/18=3/27=4/36=5/45 etc
but don't forget to convert back to ratios
so some examples are 1:9
2:18
3:27
4:35
5:45
Use present value equation.
If present value of annuity equals 400,000, then you are indifferent.
where v = 1/(1+r) and A = annual payment = 800,000/20 = 40,000
PV = 400,000
After subbing in the numbers, the equation is:
Therefore at interest rate of about 7.75% you are indifferent.
