Find all zeros of the function and write the polynomial as a product of linear factors. f(x) = 3x4 + 4x3 + 13x2 + 16x + 4

Don't try anything positive.
f(-1) = 3 - 4 + 13 - 16 + 4 = 0 This one works so one factor is (x + 1)
f(-1/3) = gives a 0. So another factor is 3x + 1
The last factor is found by dividing 3x^2 + 4x + 1 into the original equation. That's (3x + 1)(x + 1) expanded.
When you do that you find that the last factor is (x^2 + 1)
You can see how this is factored at Wolframalpha dot com

an employment agency specializing in temporary construction help pays heavy equipment operators $129 per day and general laborer

Studentka2010 [4]

To solve this problem you must apply the proccedure shown below:

1. Let's call $x$ to the number of equipment operators and $y$ to the numbers of laborers.

2. Based on the information given in the problem above, you can make a system of equation, as following:

$\left \{ {{129x+100y=3751} \atop {x+y=32}} \right.$

3. By applying the method of substitution, you can solve for $x$ from the second equation and substitute it into the first equation to solve for $y$ , as following:

$x=32-y\\ 129(32-y)+100y=3751\\ y=\frac{-377}{-29} \\ y=13$

4. Now, substitute the value of $y$ into the second equation to calculate $x$ :

$x=32-13\\ x=19$

The answer is: 19 equipment operators and 13 laborers.

Answer:

The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
