Answer:

Annual withdraw= $57,583.68

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $555,000

Interest rate (i)= 0.0825

Number of periods (n)= 20

<u>To calculate the annual withdrawals, we need to use the following formula:</u>

Annual withdraw= (PV*i) / [1 - (1+i)^(-n)]

Annual withdraw= (555,000*0.0825) / [1 - (1.0825^-20)]

Annual withdraw= $57,583.68

Which equation is y= 2x ^2 - 8x +9 rewritten in vertex form.
tankabanditka [31]
<span>y= 2x ^2 - 8x +9

</span>y = a(x - h)2 + k, where (h, k) is the vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>
