Brad bought a piece of industrial real estate for $192,345. the value of the real estate appreciated at a constant rate per year. the table shows the value of the real estate after the first and second years: year 1 2 value (in dollars) $200,038.80 $208,040.35 which function best represents the value of the real estate after t years? f(t) = 200,038.80(1.04)t f(t) = 200,038.80(0.04)t f(t) = 192,345(0.04)t f(t) = 192,345(1.04)t

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
