Hence n=8

15.

5. If "P, = 1680 and "C, = 70, find n and r.

Answer»

ANSWER:

npr=n!/(n-R)!

and ncr=n!/(n-r)!r!

given npr=1680 and ncr=70

n!/(n-r)!=1680 and n!/(n-r)!r!=70

1/r!×1680=70

r!=1680/70=24

r!=4!

r=4

np4=1680

n(n-1)(n-2)(n-3)=1680

(n^2-3n)(n^2-3n+2)=1680

let n^2-3n=t

t(t+2)=1680

t^2+2t-1680=0

t^2+42t-40t-1680=0

t(t+42)-40(t+42)=0

(t+42)(t-40)=0

t=40,-42

case1:If t=40 then n^2-3n-40=0

n^2-8n+5n-40=0

n(n-8)+5(n-8)=0

(n+5)(n-8)=0

n=8,-5

case2:if t=-42 then n^2-3n+42=0

sine D less than zero.The roots are imaginary.

Hence n=8

भय है, तुम्हें निराश देखकर छाती कहीं न फट जाये,

फिरा न लूँ अभिशाप, पिघलकर वाणी नहीं उलट जाये।'

इस प्रकार कह परशुराम ने फिरा लिया आनन अपना,

जहाँ मिला था, वहीं कर्ण का बिखर गया प्यारा सपना।

छूकर उनका चरण कर्ण ने अर्घ्य अश्रु का दान किया,

और उन्हें जी-भर निहार कर मंद-मंद प्रस्थान किया।

4. What is the value of the polynomial 4x3 + 7x2 + x - 2when x= -1.

Answer»

$If \: x = -1 \: then \: the \: value \: of\: the$

$polynomial \; 4x^{3}+7x^{2}+x-2$

$= 4(-1)^{3} + 7(-1)^{2} + (-1) - 2$

$= 4(-1) + 7\times 1 - 1 - 2$

$= -4 + 7 - 1 - 2$

$= 7 - 7$

$\green {= 0}$

THEREFORE.,

$\red{ Required \: value } \green { = 0 }$

Answer»

I PROMISE I WILL FOLLOW YOU IF YOU MARK AS BRAINLIST

THANKS FOR QUESTION

YOUR ANSWER IS

Train proceeds at 3/4 S where S is his usual speed means 1/4 decrease in the speed which will lead to 1/3 increase in the time.

[ As S *T = D, Speed is inversely proportional to time when DISTANCE is constant].

Now, the main difference come in those 24 km and the change in difference of time = 35 - 25 = 10 m

= 1 / 3 *T = 10 where T is the time required to cover the distance of (50 - 74) = 24 km

T = 30 min = 0.5 hours

Speed of the train = 24 / (0.5) = 48 kmph
