Answer:
Kevin's constant of proportionality,k = $8.25 per hour
Greg's constant of proportionality,k = $9 per hour
Savannah's constant of proportionality,k = $9.5 per hour
Step-by-step explanation:
1. What is the constant of proportionality, k, of Kevin's wage? Greg's? Savannah's?
Solution
y = kx is a proportional variation
Where,
y and x are represent two different variables
k represent constant of proportionality
From the attached table,
Let
y = wages earned (in dollars)
x = hours worked
To find the constant of proportionality k of Kevin's wage, divide the variable y (total earned) by the variable x (number of hours)
Using any points on the table
Take (8,66.00) for example
constant of proportionality k of Kevin's wage = variable y (total earned) / variable x (number of hours)
= 66.00/8
= 8.25
k = $8.25 per hour
B. Constant of proportionality of Greg's wage = variable y (total earned) / variable x (number of hours)
Using (9, 81.00)
k = 81.00/9
= 9
Greg's k = $9 per hour
C. Constant if proportionality of Savannah's wage = variable y (total earned) / variable x (number of hours)
Using (6, 57.00)
k = 57.00/6
= 9.5
Savannah's k = $9.5 per hour
Therefore,
Kevin's constant of proportionality,k = $8.25 per hour
Greg's constant of proportionality,k = $9 per hour
Savannah's constant of proportionality,k = $9.5 per hour
Trigonometry as taught is mostly about memorizing two lousy triangles, namely half a square and half an equilateral triangle. This one is half an equilateral triangle.
The respective opposite sides of the 30/60/90 triangle are in ratio
A sine of √3/2 is an opposite of √3 and a hypotenuse of 2, so opposite and hypotenuse of the 60 degree angle. (It's the mama bear, in the middle, just right.)
In the end you just have memorize the two tired triangles of trig.
