y = 15x, in 9 years he will have saved $13,500
y = x + 15, in 9 years he will have saved $2,400
y = 6x, in 9 years he will have saved $5,400
y = x + 90, in 9 years he will have saved $9,900

A. Find a quadratic function in standard form that models the path of the arrow. Then graph the function. Use quadratic regression for this step. The three points satisfy a quadratic function of form y= ax^2 +box +c
900a+30b+c=6....(1)
3600a+60b+c=7...(2)
10000a+100b+c=4....(3)
(2)-(1)
2700a+30b=1.....(4)
(3)-(1)
9100a+70b=-2...(5)
solving (4) and (5) then putting a, b into (1)
a=-13/8400, b=29/168, c=31/14
The graph is like a parabola with upward dome, it's head at upside and two legs downwards.
future value of the account after ten years.
NEED ANSWER ASAP
Answer:
$10,467.06
Step-by-step explanation:
The computation of the future value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
here
rate of interest = 8.25% ÷ 12 = 0.6875%
And, the number of years is = 12 × 10 = 120
So, the future value is
= $4,600 × (1 + 0.6875%)^120
= $4,600 × 2.275448086
= $10,467.06
