Suppose p = (1, 3, 4) and q = (5, 8, 12) are solutions to the linear system of equations: a11x1 + a12x2 + a13x3 = α1 a21x1 + a22

Alex73 [517]

Answer:

Let $A=\left[\begin{array}{ccc}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\\a_{41}&a_{42}&a_{43}\end{array}\right]$ the matrix associated to the system and

$b=\left[\begin{array}{ccc}\alpha_{1}\\\alpha_{2}\\\alpha_{3}\\\alpha_4\end{array}\right]$ the vector of constant values of the system.

The equation of the line joining p and q is

$p+t(q-p), t\in\mathbb{R}$ . Since p and q are solutions of the linear system then, $Ap=b$ and $Aq=b$

Let $w=q-p$ . Observe that $Aw=A(q-p)=Aq-Ap=b-b=0$ . Then w is a solution of the homogeneous system Ax=0.

Now, let s=p+r(q-p) for some $r\in\mathbb{R}$ be a point in the line joining p and q. Observe that

$As=A(p+r(q-p))=Ap+rA(q-p)=Ap+rAw=b+r*0=b$

Then As=b. This means that s is a solution of the linear system.

A house sits on a rectangular piece of land. Two of the sides measure 104 feet each. If all four sides add to 576 feet, how long

xxTIMURxx [149]

Answer:

Each of the other side is 184 feet.

Step-by-step explanation:

Given that:

Length of two sides each = 104 feet

Total length of all sides = 576 feet

Let,

x be the length of other one side.

Length of other two sides will be 2x.

Total length of sides = 2x + 2(104)

576 = 2x + 208

2x = 576 -208

2x = 368

Dividing both sides by 2

$\frac{2x}{2}=\frac{368}{2}\\x=184$

Hence,

Each of the other side is 184 feet.

Find the quotient of 26 divided by 10 as a decimal

larisa86 [58]

$26:10=\frac{26}{10}=\frac{20+6}{10}=\frac{20}{10}+\frac{6}{10}=2+0.6=\boxed{2.6}$
