explain one of the theorems that you would use to find the zero of higher degree polynomial
Rational Root Theorem:
If the rational number [tex]x=\frac{b}{c}[/tex] is a zero of a higher degree polynomial:
[tex]P(x)=kx^{n}+...+m[/tex]
where all the coefficients are integers. Then [tex]b[/tex] will be a factor of [tex]m[/tex] and [tex]c[/tex] will be a factor of [tex]k[/tex]
1. Use the rational root theorem to enumerate all possible rational zeroes of the polynomial [tex]P(x)[/tex]
2. Evaluate the polynomial from the first step until you can find a zero. Let’s suppose the zero is [tex]x=r[/tex]. It will be a zero if [tex]P(r)=0[/tex]. Then if this is true, write the polynomial as:
[tex]P(x)=(x-r)Q(x)[/tex]
3. Repeat this process using [tex]Q(x)[/tex] this time rather than [tex]P(x)[/tex]. The process finishes until we reach a second degree polynomial, then solve as it is widely known for a quadratic equation.
When rounding to.the nearest hundred are you to add or subtract?
Answer:
When you round to the nearest hundred:
150 or higher turns into 200, so you'd do add.
But when it's 149 or lower, you simply subtract it by 49.

All at once, pandemonium broke loose. ______________ the marching band came around the corner, dogs began barking, and the horses pulling the mayor's carriage began to run!
Which word best completes the passage above? (5 points)
Anyway
Because
Following
Simultaneously
Answer:
The answer is word SIMULTANEOUSLY.
Step-by-step explanation:
The alternative that fits best is " d.Simultaneously"
All at once, pandemonium broke loose. Simultaneously, the marching band came around the corner, dogs began barking, the horses pulling the Mayors carriage began to run.
This word maintains the coherence and cohesion of the given text.
Answer:
The alternative that fits best is " d. Simultaneously"
Step-by-step explanation:
Thus, the complete sentence would read: "All at once, pandemonium broke loose. Simultaneously the marching band came around the corner, dogs began barking, and the horses pulling the mayor's carriage began to run!"
The explanation for this is that the word "Simultaneously" is the only one that fits the phrase, and maintains the coherence and cohesion of the text. The words "anyway", "because", and "following", when embedded in the phrase, change the meaning of what the author wanted to go through.

What is the simplified form of the following expression? 10abc^2 sqrt 49a^2b^2c^2
Answer: [tex]70a^2b^2c^3[/tex] will be the answer.
Explanation:
Since Given expression is [tex]10abc^2\sqrt{49a^2b^2c^2}[/tex]
We can write, [tex]10abc^2\sqrt{49a^2b^2c^2}= 10abc^2\sqrt{7^2a^2b^2c^2}[/tex]
[tex]\Rightarrow 10abc^2\sqrt{49a^2b^2c^2}= 10abc^2\sqrt{(7abc)^2}[/tex]
[tex]\Rightarrow 10abc^2\sqrt{49a^2b^2c^2}= 10abc^27abc[/tex]
[tex]\Rightarrow 10abc^2\sqrt{49a^2b^2c^2}= 10\times7abc^2abc[/tex]
[tex]\Rightarrow 10abc^2\sqrt{49a^2b^2c^2}= 70abc^2abc[/tex]
[tex]\Rightarrow 10abc^2\sqrt{49a^2b^2c^2}= 70a^2b^2c^3[/tex]
1. The simplified form of the expression [tex]10abc^2[/tex] is simply [tex]10abc^2[/tex] itself.
2. The simplified form of the expression [tex]\sqrt{49a^2b^2c^2}[/tex] is 7abc.
1. Since there are no like terms to combine, and no operations to perform, the expression remains unchanged.
2. The expression [tex]\sqrt{49a^2b^2c^2}[/tex] represents the square root of [tex]49a^2b^2c^2[/tex]. To simplify this, we need to find the square root of each term under the radical.
[tex]\sqrt{49a^2b^2c^2} = \sqrt{49} * \sqrt{a^2} * \sqrt{b^2} * \sqrt{c^2}[/tex]
The square root of 49 is 7, and the square root of any variable raised to the power of 2 is simply the variable itself. So, we have: [tex]\sqrt{49a^2b^2c^2} = 7 * a * b * c[/tex]

The volume of a cuboid is 1404cm3. The length is 9cm and the width is 130mm. Work out the height of the cuboid in cm.
To calculate the height of the cuboid, we convert the width to centimeters and use the volume formula. After conversion, we find the height by dividing the volume (1404cm³) by the product of the length (9cm) and width (13cm), resulting in a height of 12cm.
To find the height of the cuboid, we can use the formula for calculating volume, which is volume = length x width x height. The question gives us the volume of the cuboid as 1404cm³, the length as 9cm, and the width as 130mm. However, we need to ensure all units are the same, so let's convert the width from millimeters to centimeters: 130mm = 13cm (since 1cm = 10mm).
Now, using the formula for volume:
Volume = length x width x height1404cm³ = 9cm x 13cm x heightTo find the height, we divide the volume by the product of the length and width:
height = Volume / (length x width)height = 1404cm³ / (9cm x 13cm)height = 1404cm³ / 117cm²height = 12cmTherefore, the height of the cuboid is 12cm.

18. you work a part-time job earning $6.80/hr with tips that average $2.30/hr. you work 20 hr/wk and your deductions are FICA (7.65%), federal tax withholding (8.95%), and state tax withholding (6.1%). how much are you allowed in housing expenses per month?
Im asking for help not for you to do it.
Total housing expenses per month allowed will be $168.81.
To calculate how much you are allowed in housing expenses per month, we need to first determine your after-tax income.
You earn $6.80/hr plus tips averaging $2.30/hr, resulting in an hourly wage of
$6.80 + $2.30 = $9.10
Working 20 hours a week gives you a weekly income of
20 hours × $9.10/hr = $182
Monthly, this equates
$182 4 weeks = $728
The deductions are as follows: FICA (7.65%), federal tax withholding (8.95%), and state tax withholding (6.1%). These deductions total to
7.65% + 8.95% + 6.1% = 22.7%
To get the after-tax income, we calculate
$728 - (22.7% × $728)
≈ $562.69
This is your monthly take-home pay.
Financial experts often recommend spending no more than 30% of your take-home pay on housing. Therefore
$562.69 × 30%
= $168.81 houses expenses per month

A lab worker monitors the growth of a bacteria colony starting at 9:00 a.m. At that time, there are 100 bacteria. According to the exponential function f(x) = 100(4)x, the bacteria quadruple every hour. Which equation could you use to determine the number of bacteria in the colony after 6 hours?
The equation to determine the number of bacteria in the colony after 6 hours is [tex]f(x) = 100(4)^x[/tex] and after 6 hours, there will be 409,600 bacteria in the colony.
To find the number of bacteria after 6 hours, one would substitute x with 6 in the exponential function [tex]f(x) = 100(4)^x[/tex].
This function models the growth of the bacteria colony, where the initial number of bacteria is 100 and they quadruple every hour.
The variable x represents the number of hours that have passed since the initial measurement at 9:00 a.m.
By substituting x = 6 into the function, we get:
[tex]f(6) = 100(4)^6[/tex]
Now, calculate the value of [tex](4)^6[/tex]:
[tex](4)^6 = 4 \times 4 \times 4 \times 4 \times 4 \times 4 = 4096[/tex]
Then, multiply this by the initial number of bacteria, which is 100:
f(6) = 100 [tex]\times[/tex] 4096
Finally, calculate the total number of bacteria after 6 hours:
f(6) = 409600
The relationship between the monthly fee for Brandon’s phone and the price per minute for long distance is modeled by the linear function f (x) = 0.05x + 3, where x is the number of minutes used for long distance. What is the total bill if Brandon used 20 minutes of his long distance service in a month?
the linear function f (x) = 0.05x + 3,
f(x) is the monthly fee and x is the price per minute
Brandon used 20 minutes of his long distance
So x is 20 minutes
We plug in 20 for x
f(x) = 0.05x + 3
f(20) = 0.05(20) + 3 = 4
So total bill is $4 if Brandon used 20 minutes of his long distance service in a month

The price of the land is $2300 per acre ( 1 acre = 4840) how much does the land cost?
Two of the three side lengths are given. To find the area of the triangular piece of land, we'll need to calculate the length of the third side, the side opposite the 100 degree angle. Use the Law of Cosines for this task.
a^2 = b^2 + c^2 - 2ac*cosA
Here, a^2 = 500^2 + 750^2 - 2(500)(750)cos 100 deg, or
a^2 = 250000 + 572500 - 750000(-0.1736), or
= 692264
Then a = +sqrt(692264) = 832 yds
Use Heron's Formula to find the area of the land.
First, calculate s=(a+b+c)/2: (500+750+832)/2 = 1041=s
According to Heron's Formula, A = sqrt( s(s-a)(s-b)(s-c) )
Here, A = sqrt( 1041*(1041-500)*(1041-750)*(1041-832) )
I will leave this calculation to you to complete.
Suppose the area of the land is A square yards. Convert this to acres, using the fact that 1 acre = 4840 yd^2.
In acres, the area is
1 acre
A* ---------------- = (A/4840) acres
4840 yd^2
How much will this cost? Recall that the unit cost of the land is $2300/acre.
Then the total cost will be:
$2300
(A/4840) acres * ------------- = 0.475*A dollars. (Substitute your value for A)
1 acre
