Answer:
Monthly deposit= $323.78
Step-by-step explanation:
Giving the following information:
Future Value (FV)= 12,000*0.7= $8,400
Number of periods (n)= 2*12= 24
<u>We weren't provided with the interest rate, suppose an annual interest rate of 8%.</u>
Interest rate= 0.08/12= 0.00067
<u>Now, to calculate the monthly deposit, we need to use the following formula:</u>
<u></u>
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (8,400*0.0067) / [(1.0067^24) - 1]
A= $323.78
This is a parabola by the looks of the equation and the fact that it's a satellite dish. The vertex of the equation is (-6,0) and the focus is 2/4, 1/2. 1/2 plus -6 is -5.5. the focus is (-5.5,0).
This answer is only true if the actual equation is y^2 not 2y
