A perpetuity pays 1 at the end of the 1st year, 2 at the end of the 2nd year, 3 at the end of the 3rd year, etc. Which of the following expressions give the present value of this perpetuity? I. . 1/i^2
II. 1−d/d^2
III. e^δ+e^−δ
A) I and II only
B) I and III only
C) II and III only
D) I, II and III

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
