Let's find an expression for Jan's earnings in terms of normal wage, hourly wage, and overtime wage:
x= normal hours
y= OT hours
z = holiday hours
Jan earns 11/hour on normal time.
She earns 11 * 1.5 = 16.5/hour on OT
She earns 11 * 2 = 22/hour on holidays
The expression for her earnings is:
11x + 16.5y + 22z = earnings
Plugging in her hours (40 reg, 9 OT, 12 holiday):
11(40) + 16.5(9) + 22(12) = earnings
440 + 148.5 + 264 = earnings

earnings = 852.50

Given f(x) = x3 – 2x2 – x + 2, the roots of f(x) are
kolezko [41]
You have the following expression given in the problem:

f(x) = x³ – 2x²<span> – x + 2

 Therefore, to find the roots, you must apply the proccedure shown below:

 1. You have:

 0 </span><span>= x3 – 2x2 – x + 2

 2. Then, when you factor, you obtain:

 (x-2)(x-1)(x+1)=0

 3. Therefore, you have that the roots are the following:

 x1=-1
 x2=1
 x3=2</span>

28. $400 is divided between Kas, Jaspar and Jae so that Kas has twice
Inga [223]

Let's define our variables before anything else:

Kas = S

Jaspar = R

Jae = E

$400 is divided between Kas, Jaspar and Jae

This means S + R + E = 400

Kas has twice  as much as Jaspar

This means that S = 2R

Jaspar has three times as much as Jae

This means that R = 3E

Because both of our smaller formulas have R, let's replace everything in the first formula with R

S + R + E = 400

plug in values

2R + R + R/3 = 400

multiply everything by 3 to get rid of the denominator

6R + 3R + R = 1200

add

10R = 1200

divide

R = 120

So Jaspar receives $120
