2.

Solve for x:|2x-3|+|x-1|=5

Answer»

Answer:

here u need to take 4 cases

Step-by-step explanation:

Case :- 1

2x-3+x-1=5

3x-4=5

3x=9

x=3

Case :- 2

-(2x-3)+ (-(x-1)) = 5

-(2x-3+x-1) = 5

3x-4 = -5

x = -1/3

Case :- 3

-(2x-3)+x-1=5

-2x+3+x-1 = 5

-x+2 = 5

x = -3

Case :- 4

2x-3+(-(x-1))=5

2x-3-x+1 = 5

x-2 = 5

x= 7

from all the cases ,

x = {7,3,-3,-1/3}

Answer» Step-by-step explanation: a = 11 , d = -3 nth TERM = a+(n-1)d a+(n-1)d = -150 11 + (n-1)-3 = -150 (n-1)-3 = -161 n-1 = 53.66 n = 53.66 + 1 n = 54.66 term is a WHOLE number hence 150 is not a term in this A.P

3.

Check whether -150 is a term of Ap 11 8 52

Answer»

Step-by-step explanation:

a = 11 , d = -3

nth TERM = a+(n-1)d

a+(n-1)d = -150

11 + (n-1)-3 = -150

(n-1)-3 = -161

n-1 = 53.66

n = 53.66 + 1

n = 54.66

term is a WHOLE number hence 150 is not a term in this A.P

5.	Find the value plzzzzzzz do fast friends
Answer» 10^(2y) = 25 Since the BASE is 10, we can write, log (25) = 2y => log (5^2) = 2y => 2 log (5) = 2y => log (5) = y => - log (5) = - y => log (5^(-1)) = - y => log (1/5) = - y From this, we get that, 10^(- y) = 1/5 Hence 1/5 is the answer. Here I used only ONE identity. log(x^a) = a · log (x) And conversely, a · log (x) = log (x^a) Or, we can find the answer without using logarithm! 10^(2y) = 25 => (10^y)^2 = 5^2 => 10^y = 5 Now, since 10^(2y) = 25 is given, divide LHS by 10^(2y) and RHS by 25. So, (10^y) ÷ (10^(2y)) = 5 ÷ 25 => 10^(y - 2y) = 1/5 => 10^(- y) = 1/5 So we got the answer. We can find out the answer by this too.

5.

Find the value plzzzzzzz do fast friends

Answer»

10^(2y) = 25

Since the BASE is 10, we can write,

log (25) = 2y

=> log (5^2) = 2y

=> 2 log (5) = 2y

=> log (5) = y

=> - log (5) = - y

=> log (5^(-1)) = - y

=> log (1/5) = - y

From this, we get that,

10^(- y) = 1/5

Hence 1/5 is the answer.

Here I used only ONE identity.

log(x^a) = a · log (x)

And conversely,

a · log (x) = log (x^a)

Or, we can find the answer without using logarithm!

10^(2y) = 25

=> (10^y)^2 = 5^2

=> 10^y = 5

Now, since 10^(2y) = 25 is given, divide LHS by 10^(2y) and RHS by 25. So,

(10^y) ÷ (10^(2y)) = 5 ÷ 25

=> 10^(y - 2y) = 1/5

=> 10^(- y) = 1/5

So we got the answer. We can find out the answer by this too.

23.	If the 17th term of an a.p excedsits 10th term by 14 then find the common difference
Answer» Answer: The common difference of this A.P. is 2. Step-by-step explanation: What is an A.P. ? An ARITHMETIC progession is a list of numbers in which, each term is obtained by adding a fixed NUMBER to the preceding term except the first term. Now coming to our question First you should know how to find the arithmetic progression. $a_n=a+(n-1)d$ $Where,\ a_n\ is\ the\ general\ term\ of\ the\ A.P.$ a is the first term of the A.P. d is the common difference of the A.P. n is the term of the A.P. So, the 17th term of the A.P. will be GIVEN by $17_{th}=a+(17-1)d\\17_{th}=a+(16)d\\17_{th}=a+16d$ Now, the 10TH term can be given by the equation $10_{th}=a+(10-1)d\\10_{th}=a+(9)d\\10_{th}=a+9d$ Now, it given, that the 17th term exceeds the 10th term by 14. So, the equation will BECOME $a+16d=a+9d+14\\16d-9d=14\\7d=14\\ \therefore\; d=2$

If the 17th term of an a.p excedsits 10th term by 14 then find the common difference

Answer»

Answer:

The common difference of this A.P. is 2.

Step-by-step explanation:

What is an A.P. ?

An ARITHMETIC progession is a list of numbers in which, each term is obtained by adding a fixed NUMBER to the preceding term except the first term.

Now coming to our question

First you should know how to find the arithmetic progression.

$a_n=a+(n-1)d$

$Where,\ a_n\ is\ the\ general\ term\ of\ the\ A.P.$

a is the first term of the A.P.

d is the common difference of the A.P.

n is the term of the A.P.

So, the 17th term of the A.P. will be GIVEN by

$17_{th}=a+(17-1)d\\17_{th}=a+(16)d\\17_{th}=a+16d$

Now, the 10TH term can be given by the equation

$10_{th}=a+(10-1)d\\10_{th}=a+(9)d\\10_{th}=a+9d$

Now, it given, that the 17th term exceeds the 10th term by 14.

So, the equation will BECOME

$a+16d=a+9d+14\\16d-9d=14\\7d=14\\ \therefore\; d=2$

The polynomials kxcube Plus 3X square -8 and 3X cubed minus 5X plus K are divided by X +2 if the remainder in each case is the same find the value of K

Answer»

<P>Answer:

2

Step-by-step explanation:

let, p(x) = kx³+3x²-8 & q(x) = 3x³-5x+k

given, p(x)&q(x) when DIVIDED by (x+2) gives same remainder

⇒ p(-2) = q(-2)

⇒ k(-2)³+3(-2)²-8 = 3(-2)³-5(-2)+k

⇒ -8k+12-8 = -24+10+k

⇒ 4-8k = k-14

⇒ k+8k = 4+14

⇒ 9k = 18

and HENCE k = 2

The sum of a two digit number and the number formed by interchanging the digits is 110. If 10 is subtracted from the original number the new number is 4 more than 5 times the sum of its digits in the original number. Find the original two digit number

Answer»

Answer:

64

Step-by-step explanation:

$\textbf{Let\: the\: digit\: at\: ones\:= \:M}$

and $\textbf{Digit \:at \:tens \:= \:N}$

☞ The sum of two digit number and the number formed by interchanging the digits is 110.

Let the original number be $\underline{\bold{<klux>10N</klux>\: +\: M}}$

Number formed by reversing the digit is $\underline{\bold{10M\:+\:N}}$

10N + M + 10M + N = 110

________ [AS SAID IN QUESTION]

11N + 11M = 110

11 (N + M) = 110

N + M = 10

N = 10 - M _______(eq 1)

☞ If 10 is SUBTRACTED from original number i.e. 10N + M

10N + M - 10

☞ The new number is (equal to) 4 more than 5 times the sum of it's digit in the original number.

5(M + N) + 4

• A.T.Q.

10N + M - 10 = 5(M + N) + 4

10N + M - 10 = 5M + 5N + 4

10N - 5N + M - 5M = 4 + 10

5N - 4M = 14 _______(eq 2)

5(10 - M) - 4M = 14 ___[From eq 1]

50 - 5M - 4M = 14

- 9M = 14 - 50

- 9M = - 36

9M = 36

M = 4

• Put value of M in eq 1

N = 10 - (4)

N = 6

☞ We have to FIND the original two digit numbers.

So, the original number is 10N + M

10(6) + 4

64

The original two digit number is 64.
