Subtracting 3x^4+9x^3x^2 from the dividend and bringing down by 13x, the quotient is 3x^2-2x+5, and the term 3x^2 in the quotient is the result of dividing 3x^4 by x²
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have a polynomial:
[tex]=\rm -2x^3-x^2+13x[/tex]
The dividend polynomial:
[tex]\rm = 3x^4+7x^3+2x^2+13x+5[/tex]
If we subtract the polynomial [tex]\rm 3x^4+9x^3+3x^2[/tex] from the dividend polynomial, we will get:
[tex]\rm = (3x^4+7x^3+2x^2+13x+5)-(3x^4+9x^3+3x^2)[/tex]
[tex]\rm = -2x^3-x^2+13x+5[/tex]
After bringing down 13x, we will get the polynomial:
[tex]=\rm -2x^3-x^2+13x[/tex]
If complete the division of the polynomial, we will get:
[tex]\rm = \frac{(3x^4+7x^3+2x^2+13x+5)}{x^2+3x+1}[/tex]
= [tex]=\rm 3x^2-2x+5[/tex]
Thus, the subtracting 3x^4+9x^3x^2 from the dividend and bringing down by 13x, the quotient is 3x^2-2x+5, and the term 3x^2 in the quotient is the result of dividing 3x^4 by x²

The length of a rectangle is twice its width. The perimiter of the rectangle is 36 ft what are the length and the width of the rectangle?
Answer:
W = 6', L = 12'
Step-by-step explanation:
Let W be the width and L the length.
We are told that L = 2W
The perimeter is 2L + 2W = 36'
Use the first equation in the second: 2(2W) + 2W = 36'
4W + 2W = 36'
6W = 36'
W = 6'
and since L = 2W, L = 12'
Check: Does a width of 6' and length of 12' make a perimeter of 36'?
2*6' + 2*12' = 36' ?
12'+24' = 36'
YES
The length is 12' and the width is 6'. The lenght is twice the width, and the perimeter adds to 36'.

A bag contains hair ribbons for a spirit rally. The bag contains 4 black ribbons and 5 green ribbons. Lila selects a ribbon at random, then Jessica selects a ribbon at random from the remaining ribbons. What is the probability that Lila selects a green ribbon and Jessica selects a black ribbon? Express your answer as a fraction in simplest form.
Answer:
3/15 x 12/14 = 36/210 = 6/35
Step-by-step explanation:
3 + 12 = 15
3/15 = black
12/15 = green
the probability Lila selects the black ribbon first is 12/15
Lila has taken one away so the total now decreases by one to 14
There are 3/14 black ribbons now, and hence the probability that Jessica takes one is 3/14.
Then you just multiply the two together:
3/15 x 12/14 = 36/210 = 6/35
So as a result, The simplified answer is 6/35

The binomial probability for getting at least 4 successes is 0.955
What is binomial probability?The probability of exactly x successes on n repeated trials in an experiment which has two possible outcomes is called binomial probability.
Binomial probability formula[tex]P_{x} = nC_{x} p^{x} q^{n-x}[/tex]
Where,
P is the binomial probability
x is the number of times for a specific outcomes within n trials
[tex]nC_{x}[/tex] is the number of combinations
p is the probability of success in a single trial
q is the probability of failure on a single trial
n is the number of trials
Let p denote the probability of getting success in a single trial and q denotes the probability of failure in a single trial.
And let x be a random variable denoting the number of success.
According to the given question.
We have
[tex]p = 0.85[/tex]
⇒[tex]q = 1- 0.85 = 0.15[/tex]
Also,
n = 6
Therefore,
The binomial probability of getting at least 4 success
[tex]=P(x\geq 4)[/tex]
[tex]=P(x=4)+P(x=5)+P(x=6)[/tex]
[tex]= 6C_{4} (0.85)^{4} (0.15)^{2} + 6C_{5} (0.85)^{5} (0.15)^{1}+ 6C_{6} (0.85)^{6} (0.15)^{0}[/tex]
[tex]=\frac{6!}{4!21} (0.522)(0.0225)+\frac{6!}{5!1!} (0.443)(0.15)+\frac{6!}{6!0!} (0.4)[/tex]
[tex]=15(0.011)+6(0.066)+1(0.4)[/tex]
[tex]=0.165+0.396+0.4\\=0.955[/tex]
Hence, the binomial probability for getting at least 4 successes is 0.955
Thus, option A is correct.

Answer: 36
Step-by-step explanation: 6 + 3 = 9.
4 * 9 = 36
Veronica's statement is reasonable because they cost more than $30.
The total amount of sandwiches is $36
Calculations and Parameters:Given that:
She buys 1 sandwich for $4
She buys 6 ham sandwiches and 3 cheese sandwiches
To find the total cost for Veronica would be:
6+3 = 9 total sandwiches
4 * 9= 36 total cost of the sandwiches.

Belle is going to make chili for a football party. It will take 1 hour and 10 minutes to prepare all the ingredients and assemble them in the pot. Then, the chili will need to simmer for 1 hour and 40 minutes. What is the latest time Belle can start preparing the ingredients if the chili needs to be ready at 4:00 P. M. ?
Answer:
1:10pm
Step-by-step explanation:
1st, you add all the time needed to make the chili & cook it.
1 hour + 10 minutes + 1 hour + 40 minutes = 2 hours & 50 minutes.
Now you work backwards from 4:00pm.
You go back 2 hours & you would be at 2:00pm
Now you go back another 50 minutes & you would be at 1:10pm
To double check, you can add 2 hours & 50 minutes to 1:10pm & you would get 4:00pm

Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3
How to get the volume of the sphere?
For a sphere of radius R, the volume is given by the formula:
[tex]V = (\frac{4}{3})*3.14*R^3[/tex]
In this case, we can see that the diameter is 9 cm, then the radius is half of that:
R = 9cm/2 = 4.5cm
Now that we know the radius, we can replace it on the volume formula to get:

dog again?
Explain your answer.
Answer:
they wont need to hire someone for nine months.
Charlie will be gone in 6 months, while Dash has 3 more months after til she leaves.
Answer: 18 months
Step-by-step explanation:
If both of them aren't at home, then they hire someone to look after the dog. However, if Charlie is on a trip and Dasha isn't, they don't. So they would need to be at business trips at the same time and that means they will hire someone to look after the dog. So we find the LCM of 6 and 9 which is 18 months.
