f a(x) and b(x) are linear functions with one variable, which of the following expressions produces a quadratic function?

ArbitrLikvidat [17]

You don't show the details but you would have to multiply two linear equations to produce a quadratic equation. ex:

y2*y1=(ax+b)(cx+d)=acx^2+(ad+bc)x+bd

If you buy a school raffle ticket for $1, your overall probability of winning at least one of the prizes is 0.04. you can improv

ser-zykov [4K]

By buying 2 tickets you doubled the probability of you winning something. So, the probability that one of your tickets will win something is 0.08. Hope this helps :)

If u+v+w=0, show that u x v = v x w = w x u.

Flauer [41]

Take the cross product of both sides of $\mathbf u+\mathbf v+\mathbf w=\mathbf0$ with $\mathbf u,\mathbf v,\mathbf w$ to generate a system of three simultaneous equations.

$(\mathbf u+\mathbf v+\mathbf w)\times\left\{\begin{matrix}\mathbf u\\\mathbf v\\\mathbf w\end{matrix}\right\}=\mathbf0\times\left\{\begin{matrix}\mathbf u\\\mathbf v\\\mathbf w\end{matrix}\right\}$
$\implies\begin{cases}\mathbf u\times\mathbf u+\mathbf u\times\mathbf v+\mathbf u\times\mathbf w=\mathbf0\\\mathbf v\times\mathbf u+\mathbf v\times\mathbf v+\mathbf v\times\mathbf w=\mathbf0\\\mathbf w\times\mathbf u+\mathbf w\times\mathbf v+\mathbf w\times\mathbf w=\mathbf0\end{cases}$
$\implies\begin{cases}\mathbf u\times\mathbf v+\mathbf u\times\mathbf w=\mathbf0\\\mathbf v\times\mathbf u+\mathbf v\times\mathbf w=\mathbf0\\\mathbf w\times\mathbf u+\mathbf w\times\mathbf v=\mathbf0\end{cases}$

since $\mathbf x\times\mathbf x=\mathbf0$ for any vector $\mathbf x$ .

Finally, use the fact that the cross product is anticommutative, i.e. $\mathbf x\times\mathbf y=-\mathbf y\times\mathbf x$ . The conclusion follows.
