True or False

Mathematics
1 answer:
Rama09 [41]4 years ago
7 0

Answer:

True

Step-by-step explanation:

Permutation is act of arranging members of a set while combination is selection of the items from collection.

The number of permutation of r object out of n is:

^nP_r=\frac {n!}{(n-r)!}

The number of combinations of r object out of n is:

^nC_r=\frac {n!}{(n-r)!\times r!}

Or,  

^nC_r=\frac {^nP_r}{r!}

So, number of the permutations of r objects out of n is greater than number of the combinations of r objects out of n.

Let r3 have the euclidean inner product. let u = (-1, 1, 1) and v = (-7, 6, 15). if ||ku + v||= 7, what is k? give the exact ans
amm1812
Mak\mathbf u+\mathbf v=k(-1,1,1)+(-7,6,15)=(-k-7,k+6,k+15)

Recall that for a vector \mathbf x\in\mathbb R^n, we have \|\mathbf x\|=\sqrt{\mathbf x\cdot\mathbf x}. So we have

\|k\mathbf u+\mathbf v\|=\sqrt{(k\mathbf u+\mathbf v)(k\mathbf u+\mathbf v)}=7
\implies k^2\mathbf u\cdot\mathbf u+2k\mathbf u\cdot\mathbf v+\mathbf v\cdot\mathbf v=49
\implies3k^2+56k+261=0
\implies k=-9,-\dfrac{29}3
