Convert the following concentration to a percent solution.

A 28.6 lb dog needs an injection at a dosage of 20 mg/kg. If the drug concentration is 95 mg/mL, how many milliliters will you administer?

Give the concentration for the following solution in mg/mL  

Let u=123,v=456\mathbf u = \begin{bmatrix} 1 \\ 2 \\3 \end{bmatrix}, \mathbf v = \begin{bmatrix} 4 \\ 5\\6\end{bmatrix} , and b=210 \mathbf b = \begin{bmatrix} 2 \\ 1\\0\end{bmatrix} a. (2 points) Write any three vectors in Span {u,v} \{\mathbf u, \mathbf v \} b. (6 points) Determine if b\mathbf b lies in Span {u,v} \{\mathbf u, \mathbf v \}

If a set of vectors spans ℝ², then any vector in ℝ² can be written as a linear combination of those vectors.
