Which statement about the relation is correct?
A
The relation is a function because each input has exactly one output.
B
The relation is a function because each output has exactly one input.
С
The relation is not a function because one input has more than one output.
let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ
for 3.5 south, y = -3.5
for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30
for 15 west, x = -15
total x = 8.2 * cos 30 – 15 ≈ -7.9
total y = -3.5 + 8.2 * sin 30 = 0.6
magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5
the magnitude is approximately 7.9 m
tan θ = y/x = 0.6/-7.9
the angle is approximately 4.3˚ north of west

Answer from: Quest
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.
