Part 1
Total paid
=cost of the bond+commission
Total paid
32×96.7+32×10=3,414.4
Part 2
Annual interest
32×96.7
=3,094.4
3,094.4×0.08625
=266.892...Annual interest
Part 3
The effective interest rate
((1+0.08625÷12)^(12)−1)×100
=8.974%
It is D because you would do x+6 and would get y so it represents direct proportion
Im not sure but i found the answer as n= 52
1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you substitute the values into the quadratic equation and simplify ir, you obtain that the result is:
-10</span>±5√2 (It is the last option).
