For each of these relations on the set {1, 2, 3, 4}, decide whether it is reflexive, whether it is symmetric, whether it is antisymmetric, and whether it is transitive. a) {(2,2),(2,3),(2,4),(3,2),(3,3),(3,4 )} 7. is reflexive, symmetric, antisymmetric, and/or transitive, where (x, y) ∈ R if and only if {(1, 1), (1, 2), (2, 1), (2, 2), (3, 3), (4, 4)} {(2, 4), (4, 2)} {(1, 2), (2, 3), (3, 4)} {(1, 1), (2, 2), (3, 3), (4, 4)} b) c) d) e)

so what is the problem what are they asking you to solve

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
