1.

.Examine Whether (x-3) is a factor of x^3-4x^2+x+6.

Answer»

$\huge\bf\purple{Polynomials}$

FIRST we will FIND the the ZERO of x-3 that will be-

$x - 3 = 0$

$x = 0 + 3$

$x = 3$

______________________________________

Now,

$p(x) = x {}^{3} - 4x {}^{2} + x + 6$

$p(3) =(3)^{3} - 4(3) {}^{2} + (3) + 6$

$=>27 - 36 + 3 + 6$

$= > 0 \: ans$

______________________________________

$\therefore$ x-3 is the FACTOR.

Answer» Given: An ENGLISH letter ‘T’ SHAPE is made by sticking TOGETHER 2 cuboids as SHOWN in the adjoining fig-1. To find: Find the total volume of the letter T. Solution: From given, we have, An English letter ‘T’ shape is made by sticking together 2 cuboids as shown in the adjoining fig-1. Consider the attached figure while going through the following steps. From the figure its clear that, the dimensions of first cuboid is 7 cm * 2 cm * 2m The volume of the first cuboid is = 7 * 2 * 2 = 28 m^3 The dimensions of the second cuboid is 5 cm * 2 cm * 2m The volume of the second cuboid is = 5 * 2 * 2 = 20 m^3 The total volume of the letter T is = volume of the first cuboid + volume of the second cuboid = 28 + 20 = 48 m^3 Therefore, the total volume of the letter T is 48 m^3

An English letter ‘T’ shape is made by sticking together 2 cuboids as shown in the adjoining fig-1. Find the total volume of the letter T. will mark as brainliest for first answer

Answer»

Given:

An ENGLISH letter ‘T’ SHAPE is made by sticking TOGETHER 2 cuboids as SHOWN in the adjoining fig-1.

To find:

Find the total volume of the letter T.

Solution:

From given, we have,

An English letter ‘T’ shape is made by sticking together 2 cuboids as shown in the adjoining fig-1.

Consider the attached figure while going through the following steps.

From the figure its clear that,

the dimensions of first cuboid is 7 cm * 2 cm * 2m

The volume of the first cuboid is = 7 * 2 * 2 = 28 m^3

The dimensions of the second cuboid is 5 cm * 2 cm * 2m

The volume of the second cuboid is = 5 * 2 * 2 = 20 m^3

The total volume of the letter T is = volume of the first cuboid + volume of the second cuboid

= 28 + 20

= 48 m^3

Therefore, the total volume of the letter T is 48 m^3

13.

If -5 is a root of the quadratic equation 2x2+px-15=0 and the quadratic equation p(x2+x)+k=0 has equal roots, find the value of k.

Answer»

<P>Given equation

px(x-3) + 9 = 0

px^2 - 3px + 9 = 0

As ROOTS are equal then determinant D should be equal to 0.

We know, D = b^2 - 4ac

Then,

(-3p)^2 - 4*p*9 = 0

9p^2 - 36p = 0

p(p - 4) = 0

p = 0, 4

0 VALUE not possible

Therefore value of p = 4

31.

The zeros of the polynomial m^3 -3m^2+m+1 are a-b , a , a+b , find a and b

Answer»

Step-by-step EXPLANATION:

The given polynomial is

p(m)= m³-3m²+m+1.

So sum of the zeroes=a-b+a+a+b=-(-3)/1=3

=> 3a=3

=> a=3/3

=> a=1

(a-b)a+a(a+b)+(a-b)(a+b)=1

=> a²-ab+a²+ab+a²-b²=1

=> 3a²-b²=1

=>1×3-b²=1

=> b²=3-1=2

=> b=±√2

So the value of a=1 and b=±√2.(answer)

45.	A box contains prime numbered cards between 1 to 100.find the probability of getting twin prime numbered cards
Answer» ANSWER: The probability of getting a twin prime numbered card = 1 / 20 (or) 0.05. GIVEN: A box contains prime numbered cards between 1 to 100. TO FIND: The probability of getting a twin prime numbered card. EXPLANATION: Sample space (S) = {1, 2, 3, 4, ……… , 100} Let A be the event of getting a twin prime number. Prime numbers = (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97) Twin prime numbers: Twin prime numbers are those prime numbers which have a difference of 2. A = {13, 31, 53, 79, 97} Difference between the numbers is two. 3 - 1 = 3 - 1 = 5 - 3 = 7 - 9 = 7 - 9 = 2 P(A) = n(A) / n(S) n(A) = 5 n(S) = 100 p(A) = 5 / 100 p(A) = 1 / 20 (or) 0.05 Hence the probability of getting a twin prime numbered card = 1 / 20 (or) 0.05. SOME MORE POINTS: Probability of a sure event is 1. Probability of an IMPOSSIBLE event is 0. Probabilty of any event always lies between 0 and 1 (0 ≤ p ≤ 1). In a sure event n(A) will be equal to n(S). In an impossible event n(A) will be equal to zero. P(S) = 1 (always) because here also n(A) = n(S), P(S) = n(S) / n(S) = 1.

A box contains prime numbered cards between 1 to 100.find the probability of getting twin prime numbered cards

Answer»

ANSWER:

The probability of getting a twin prime numbered card = 1 / 20 (or) 0.05.

GIVEN:

A box contains prime numbered cards between 1 to 100.

TO FIND:

The probability of getting a twin prime numbered card.

EXPLANATION:

Sample space (S) = {1, 2, 3, 4, ……… , 100}

Let A be the event of getting a twin prime number.

Prime numbers = (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97)

Twin prime numbers:

Twin prime numbers are those prime numbers which have a difference of 2.

A = {13, 31, 53, 79, 97}

Difference between the numbers is two.

3 - 1 = 3 - 1 = 5 - 3 = 7 - 9 = 7 - 9 = 2

P(A) = n(A) / n(S)

n(A) = 5

n(S) = 100

p(A) = 5 / 100

p(A) = 1 / 20 (or) 0.05

Hence the probability of getting a twin prime numbered card = 1 / 20 (or) 0.05.

SOME MORE POINTS:

Probability of a sure event is 1.

Probability of an IMPOSSIBLE event is 0.

Probabilty of any event always lies between 0 and 1 (0 ≤ p ≤ 1).

In a sure event n(A) will be equal to n(S).

In an impossible event n(A) will be equal to zero.

P(S) = 1 (always) because here also n(A) = n(S), P(S) = n(S) / n(S) = 1.
