Factorise 2x^3-x^2-13x-6​

Answer»

Answer:

(x-2) is factor

Step-by-step explanation:

Answer

F(x) = 2x3 + x2 − 13x + 6.

Factors of CONSTANT term 6 are ±1, ± 2, ± 3, ± 6.

Putting x = 2, we have:

f(2) = 2(2)3 + 22 − 13 (2) + 6 = 16 + 4 − 26 + 6 = 0.

Hence (x − 2) is a factor of f(x).

In a survey it was found that the ratio of the people who liked modern song and folk song is 8:9 out of them 50 people liked both song 40 like folk song only and it is like none of the song then find the number of people who participated in the survey

Answer»

Step-by-step explanation:

In a survey of a group of people, it was found that 70% of the people LIKE folk SONGS, 60% like modern songs. 4000 people liked both of them and 10% liked none of them. How many of the people were surveyed? Please solve it using set formulas.

As written, the answer to this question is all of them were surveyed. ;-)

However, I think you mean how many people are in the group that was surveyed.

Given a world divided only into those who do/don’t like folk/modern music: you have four possibilities: A: Like Folk, Dislike Modern, B: Like Folk, Like Modern, C: Dislike Folk, Like Modern, and D: Dislike Folk, Dislike Modern.

Since these four possibilities are all there are, they have to sum to 100%.

Thus, 100% = % Like Folk, Dislike Modern + % Like Folk, Like Modern + % Dislike Folk, Like Modern + % Dislike Folk, Dislike Modern

Your problem statement tells us 10% like neither (group D). It further tells us that 70% like Folk and 60% like Modern.

10% + 70% + 60% > 100% (= 140%).

Therefore, because we can’t have more than 100%, we know that the DIFFERENCE between 140% and 100% must be accounted for by the fact that 40% like both Modern and Folk. So, 30% must only like Folk and and 20% must only like Modern.

So, going back to our original equation, we get

100% = 30% + 40% + 20% + 10%.

If the 4,000 people that like both are 40% of the group, you SIMPLY divide 4,000 by .4 to DISCOVER the whole group consists of 10,000

10,000 = 3,000 + 4,000 + 2,000 + 1,000.

Solution:-

n(F)=70%,n(M)=60%and n(F intersection M)=4000,n(FUM)'=10%

We have,n(U)=100%

Now,

n(AUB)=n(U)-n(AUB)'

n(FUM)=100%-10%=90%

Again,(FUM)=70/100*x+60/100*x-4000

90/100*x=7x/10+6x/10–4000

9x/10+4000=7x/10+6x/10

9x+40000/10=15x/10

90x+400000=150x

90x-150x=-400000

-60x=-400000

X=400000/60

Let N = number of people surveyed.

Let F = those who like folk songs.

Let M = those who like modern songs.

Let f = those among F who also like modern songs.

Let m = those among M who also like folk songs.

f+m = 4,000.

(0.7)*N+(0.6)*N+(0.1)*N = (1.4)*N.

F+M+(0.1)*N = N.

F+M = (0.9)*N

F+M+f+m+(0.1)*N = (1.4)*N.

(0.9)*N+4,000+(0.1)*N = (1.4)*N.

4,000 = (1.4–0.9–0.1)*N.

N = 4,000/(0.4) = 10,000.

Find the series of f(x) =x² in (0.2π)​

Answer»

Step-by-step EXPLANATION:

Since this an even function, all of the Fourier COEFFICIENTS for the sine terms are zero, bn=0 .

The constant TERM at the beginning of the Fourier series, which represents the mean value of the function over its defined periodic interval, is:

1π∫π0xsin(x)dx=1 .

To get the Fourier coefficients for the cosine terms, an , use the trigonometry identity:

SIN(x)cos(nx)=12(sin(x−nx)+sin(x+nx))

or

sin(x)cos(nx)=12(sin(−(n−1)x)+sin((n+1)x))

to simplify the INTEGRAL:

an=2π∫π0xsin(x)cos(nx)dx

The resulting Fourier series is:

f(x)=1−12cos(x)−2∑∞n=2(−1)n(n2−1)cos(nx)

check whether the value of the x given against each polynomial is a zero of that polynomial or not :​

Answer»

Answer:

GIVEN polynomial:

  • p(x) = x² - 5x + 4

Given value for x:

Explanation: To solve this question we have to PUT 1 and 4 respectively in the given polynomial at the place of x then if we get our final result as 0 then it is the zero and if we didn't get 0 then it is not a zero of the given polynomial.

Required solution:

~ Put x as 1 in the polynomial!

→ p(x) = x² - 5x + 4

→ p(1) = (1)² - 5(1) + 4

→ p(1) = 1 - 5 + 4

→ p(1) = 1 - 1

→ p(1) = 0

  • Henceforth, 1 is the zero of given polynomial.

~ Put x as 4 in the polynomial!

→ p(x) = x² - 5x + 4

→ p(4) = (4)² - 5(4) + 4

→ p(4) = 16 - 20 + 4

→ p(4) = 16 - 16

→ p(4) = 0

  • Henceforth, 1 is ALSO the zero of given polynomial. \:

Henceforth, verified!

1 by 8 having numerator 80

Answer»

Answer:

What is 1/8 of 80?

In this article, we'll show you exactly how to calculate 1/8 of 80 so you can work out the fraction of any number quickly and easily! Let's get to the MATH!You probably know that the number above the fraction LINE is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.Here's a little TIP for you. Any number can be converted to fraction if you use 1 as the denominator:

80

1

So now that we've converted 80 into a fraction, to work out the answer, we put the fraction 1/8 side by side with our new fraction, 80/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:1 x 80

8 x 1

=

80

8

In this case, our new fraction can ACTUALLY be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 80 and 8 is 8.

We can now divide both the new numerator and the denominator by 8 to simplify this fraction down to its lowest terms.

80/8 = 10

8/8 = 1

When we put that together, we can see that our complete answer is:

10

1

The complete and simplified answer to the question what is 1/8 of 80 is:

10
