Answer:
d. $137,604
Step-by-step explanation:
The amortization formula is good for this. It tells you the principal P that must be invested to support payments of A each year for t years when the interest rate is r:
P = A(1 -(1 +r)^-t)/r
P = $12,000(1 -1.06^-20)/0.06 ≈ $137,639.05
The closest answer choice is $137,604.
1.
<span>(x-4)^2 -28 = 8
</span>(x-4)^2 = 8 + 28 = 36
<span>(x-4) = +/-6
x = 6 + 4 or -6 + 4
x = 10 or -2
2.
Mistake in </span><span>Step 5: x – 3 = 16
</span><span>Step 4: (x – 3)² = 16
</span><span>Step 5: (x – 3) = +/-4
Step 6: x = 4 + 3 or -4 + 3
Step 7: x = 7 or -1
3.
</span><span>x^2 - 4x + 3 = 0
</span><span>quadratic eqn x = [-b +/- sqrt(b^2-4ac)]/2a
where in this case
a = 1, b = -4, c = 3
x = </span> [-(-4) +/- sqrt((-4)^2-4*1*3)]/2*1
= [4 +/- sqrt(16 - 12)]/2
<span>= [4 +/- sqrt(4)]/2
= [4 +/- 2]/2
= 6/2 or 2/2
= 3 or 1
