Vector Functions and Parametric Equations
A bow-and-arrow hunter walks toward the origin along the positive x-axis, with unit speed; at time 0 he is at x = 10. His arrow (of unit length) is aimed always toward a rabbit hopping with constant velocity √5 in the first quadrant along the line y = 2x; at time 0 it is at the origin.
a) Write down the vector function A(t) for the arrow at time t.
b) The hunter shoots (and misses) when closest to the rabbit; when is that?

Answer:
$347,600
Step-by-step explanation:
There is fixed startup cost of 242,000 no matter how many units they product.
Also, each unit costs 6 to produce, so to produce 17,600 items, it's going to cost:
17,600 * 6 = 105,600
Along with this the fixed startup cost of 242,000, would make total cost:
Total cost = 242,000 + 105,600 = $347,600
