Five deposits of 100 are made into a fund at two-year intervals with the first deposit at the beginning of the first year. the fund earns interest at an annual effective rate of 4% during the first six years and at an annual effective rate of 5% thereafter. calculate the annual effective yield rate earned over the investment period ending at the end of the tenth year.

(a) 4.18%
(b) 4.40%
(c) 4.50%
(d) 4.58%
(e) 4.78%

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.

range is infinite on both x and y axis positive and negative
