45.	If y = 4/3 is a zero of the polynomial p(y) =6y³ - 11y² + ky – 20, then the value of k is answer this to get brain list
Answer» ONG>Answer: Required VALUE of k is 19 Step-by-step explanation: $p(y)=6y^{3}-11y^{2}+ky-20$ Since, y=4/3 is a zero of the POLYNOMIAL p(y). THEREFORE, $p(\frac{4}{3} )=0\\=>6(\frac{4}{3}) ^{3}-11(\frac{4}{3}) ^{2}+k(\frac{4}{3})-20=0\\=> \frac{384}{27} -\frac{176}{9}+\frac{4k}{3}-20=0\\=>\frac{384-528+36k-540}{27}=0\\=> -684+36k=0\\=>36k=684\\=>k=\frac{684}{36}\\=>k=19$ ___________________________* //HOPE this will helped you// //Please Mark it as Brainliest//

If y = 4/3 is a zero of the polynomial p(y) =6y³ - 11y² + ky – 20, then the value of k is answer this to get brain list

Answer» ONG>Answer:

Required VALUE of k is 19

Step-by-step explanation:

$p(y)=6y^{3}-11y^{2}+ky-20$

Since, y=4/3 is a zero of the POLYNOMIAL p(y).

THEREFORE,

$p(\frac{4}{3} )=0\\=>6*(\frac{4}{3}) ^{3}-11*(\frac{4}{3}) ^{2}+k*(\frac{4}{3})-20=0\\=> \frac{384}{27} -\frac{176}{9}+\frac{4k}{3}-20=0\\=>\frac{384-528+36k-540}{27}=0\\=> -684+36k=0\\=>36k=684\\=>k=\frac{684}{36}\\=>k=19$

Answer» n, result vector of a and B is perpendicular to a and its magnitude is half of b. Now, direction of vector in triangle law of addition is unique direction of each vector.so,ANGLE between two is 180- c.let c is angle between two given line.since required angle is angle between two vector are in same plane which is 180-c.HENCE using sinc=mag(resultant/vector b)=b/2/b=1/2,c=30,hence 180-c=180–30=150 hope this answer helps you PLEASE mark this answer as brainalist and follow me to answer your more questions
