Prove that the root of x^2+(1-k)x+k-3=0 are real for all real values of k​

Answer» ROOTS of a quadratic EQUATION are real WHENEVER the discriminant is non-negative. For the function given, the discriminant is

(1+k)2–4(1)(−k) , which SIMPLIFIES as

k2+6k+1 .

To determine when this is non-negative, we note that its zeros are at

−6±36–4√2 , which are

−3–22–√ and −3+22–√ . Since this expression is quadratic, it can be graphed as a parabola which opens upward, and so is non-negative to the left of the first ZERO, and to the right of the second zero. Consequently, the roots of the original function are real for values of k in

(−∞,−3–22–√]∪[−3+22–√,∞) , so NOT for all values of k.

A man spends 1/7th part of his income on food 1/2th part of remaining on clothes and 1/3rd part of remaining on entertainment. If he is left with Rs. 600, find his total income​

Answer»

ong>Step-by-step EXPLANATION:

Let man's salary be RS. N

Money SPEND on food =N/7

Money spends on clothing = (N - N/7) x 1/2 = (6N/7) x (1/2) =3N/7

Money spend on entertainment = (N - N/7 - 3N/7)/3 = (7N - 4N)/7 = N/7

Now, money left =600

⇒ N - N/7 - 3N/7 - N/7 = 600

⇒ 7N - 5N/7 = 600

⇒ N = 600 x 7/2 = Rs. 2100

∴ Money spend on entertainment = 1/7 x 2100 = Rs. 300

29.

The sum of first terms of an AP is given by Sn=2n2 +8n . Find the sixteenth term of the AP. ​

Answer»

EXPLANATION.

Sum of first terms of an A.P.

⇒ Sₙ = 2n² + 8n.

As we know that,

⇒ Tₙ = Sₙ - Sₙ₋₁.

⇒ 2n² + 8n - [2(N - 1)² + 8(n - 1)].

⇒ 2n² + 8n - [2(n² + 1 - 2n) + 8n - 8].

⇒ 2n² + 8n - [2n² + 2 - 4n + 8n - 8].

⇒ 2n² + 8n - [2n² + 4n - 6].

⇒ 2n² + 8n - 2n² - 4n + 6.

⇒ 8n - 4n + 6.

⇒ 4n + 6. = Algebraic expression.

As we know that,

Put the value of n = 1 in equation, we get.

⇒ 4(1) + 6.

⇒ 4 + 6.

⇒ 10.

Put the value of n = 2 in equation, we get.

⇒ 4(2) +  6.

⇒ 8 + 6.

⇒ 14.

Put the value of n = 3 in equation, we get.

⇒ 4(3) + 6.

⇒ 12 + 6.

18.

Put the value of n = 4 in equation, we get.

⇒ 4(4) + 6.

⇒ 16 + 6.

⇒ 22.

Their Series = 10, 14, 18, 22,,,,,,,

First term of an A.P. = a = 10.

Common difference = d = B - a = 14 - 10 = 4.

As we know that,

General terms of an A.P.

⇒ Tₙ = a + (n - 1)d.

⇒ T₁₆ = a + (16 - 1)d.

⇒ T₁₆ = a + 15d.

⇒ T₁₆ = 10 + 15(4).

⇒ T₁₆ = 10 + 60.

⇒ T₁₆ = 70.

                                                                                                                         

MORE INFORMATION.

Supposition of terms in A.P.

(1) = Three terms as : a - d, a, a + d.

(2) = Four terms as : a - 3d, a - d, a + d, a + 3d.

(3) = Five terms as : a - 2D, a - d, a, a + d, a + 2d.

A divisor for a number is such a number that when on dividing the number given 0 as remainder. A prime number is a natural number which has exactly 2 divisors i.e 1 and the number itself. Some examples of the primenumbers are 2, 3, 5, 7 etc. whereas two numbers are said to be coprime with each other when they don't haveany common factors other than 1. The number of coprimes for a number X is the count of the numbers whichare less than the given number and is coprime with X. For example, the number of coprimes for 5 is 4.If P is the smallest number such that each of its divisors are at least 15 numbers a part and P has exactly 3divisors.
