I'm guessing 10 days, since you lost a bit more than half of the workers, and it would take longer for the job to get done.

Answer:

sin(x) = -sqrt2/2

tan(x) = -1

Step-by-step explanation:

Because it is between 270 and 360, sin is negative, so it is -sqrt2/2.

tan(x) is sin(x)/cos(x), so it is just -1.

We're told (and we can confirm) that $v_3=2v_1-3v_2$ , so $v_3$ is a linear combination of the other two vectors.

This means <em>H</em> is sufficiently spanned by $\{v_1,v_2\}$ ; no need for the third vector.

But this also means we can write either $v_1$ as a linear combination of $\{v_2,v_3\}$ , and $v_2$ as a lin. com. of $\{v_1,v_3\}$ . So any set of these three vectors taken two at a time will span the subspace <em>H</em>. Hence all of b, c, and d are acceptable.
