Therefore, the point

Use online graphing calculator and draw the graph of

From Figure 1 it can be noted that the point

Consider the point

Therefore, the point

By substituing the point

Thus, the point

And from Figure 1 it can be seen that the points

Therefore, due to this multiple identity, the point

An observational study is retrospective if it considers only existing data. It is prospective if the study design calls for data to be collected as time goes on. Tell which of the following observational studies are retrospective and which are prospective. In a study of post-traumatic stress disorder, soldiers who have been in combat are given biannual physical and psychological tests for five years after they return from active duty.

Let there be a linear transformation going from ${\mathbb{R}}^{3}$ to ${\mathbb{R}}^{2}$, defined by $T(x,y,z)=(x+y,2z-x)$. Find the transformation matrix if base 1:

$\u27e8(1,0,-1),(0,1,1),(1,0,0)\u27e9$,

base 2: $\u27e8(0,1),(1,1)\u27e9$

An attempt at a solution included calculating the transformation on each of the bases in ${\mathbb{R}}^{3}$, (base 1) and then these vectors, in their column form, combined, serve as the transformation matrix, given the fact they indeed span all of ${B}_{1}$ in ${B}_{2}$

Another point: if the basis for ${\mathbb{R}}^{3}$ and ${\mathbb{R}}^{2}$ are the standard basis for these spaces, the attempt at a solution is a correct answer.

$\u27e8(1,0,-1),(0,1,1),(1,0,0)\u27e9$,

base 2: $\u27e8(0,1),(1,1)\u27e9$

There are efficient algorithms for solving a system of linear equations of the form

$\mathrm{\forall}i\phantom{\rule{2em}{0ex}}0={a}^{i}+\sum _{j}{b}_{j}^{i}{x}^{j}$

or

$\mathbf{0}=\mathbf{a}+\mathbf{b}\cdot \mathbf{x}$

Are there efficient algorithms for solving a system of quadratic equations of the form

$\mathrm{\forall}i\phantom{\rule{2em}{0ex}}0={a}^{i}+\sum _{j}{b}_{j}^{i}{x}^{j}+\sum _{k}\sum _{j}{c}_{jk}^{i}{x}^{j}{x}^{k}$

or

$\mathbf{0}=\mathbf{a}+\mathbf{b}\cdot \mathbf{x}+\mathbf{c}\cdot \mathbf{x}\cdot \mathbf{x}$

and if so, what are they?
