Answer:

Not a Solution

Step-by-step explanation:

We are given two inequalities which are

y ≤ x -4                        .............(i)

-x+3y>-4                       ............(ii)

Also we are given an ordered pair which is (5, 1/3)

Now from this order pair we see that

x = 5 and y = 1/3

Because in an ordered pair the first element represents the x value while the second value represent the y value

Now to find whether this order pair satisfies the given inequality or not we have to plugin the values of x and y in both inequalities separately and see whether it satisfies the in equality or not

Taking First inequality:

which is

y ≤ x -4

Putting x = 5 and y = 1/3 in inequality

it becomes

\frac{1}{3} ≤ 5 -4

\frac{1}{3} ≤ 1             ∵ which is true

So this inequality holds the order pair

Taking second inequality:

which is

-x+3y> -4

Putting x = 5 and y = 1/3 in inequality

it becomes

-5+\frac{1*3}{3} >  -4

-5+1 >-4        

-4>-4                            ∵ which is false because - 4 = - 4

So this inequality does not holds the order pair

So the order pair is not solution of the given inequalities because of the reason that second inequality is not satisfied

In a circle a chord 10 inches long is parallel to a tangent and bisects the radius drawn to the point of tangency. How long is t
Lorico [155]
Check the picture below.

keeping in mind that the point of tangency for a radius line and a tangent is alway a right-angle, since the "red" chord is parallel to the "green" tangent line outside, then the chord is cutting the "green" radius there in two equal halves at a right-angle, as you see in the picture.

we know the chord is 10 units long, so 5 + 5, since is perpendicularity with the radius will also cut the chord in two equal halves.

anyhow, all that said, we end up with triangle you see on the right-hand-side, and then we can just use the pythagorean theorem.

\bf \textit{using the pythagorean theorem}
\\\\
c^2=a^2+b^2
\qquad 
\begin{cases}
c=hypotenuse\\
a=adjacent\\
b=opposite\\
-------\\
c=2a\\
a=a\\
b=5
\end{cases}\implies (2a)^2=a^2+5^2

\bf (2^2a^2)=a^2+25\implies 4a^2=a^2+25\implies 3a^2=25
\\\\\\
a^2=\cfrac{25}{3}\implies a=\sqrt{\cfrac{25}{3}}\implies a=\cfrac{\sqrt{25}}{\sqrt{3}}\implies a=\cfrac{5}{\sqrt{3}}
\\\\\\
\textit{and then we can \underline{rationalize the denominator} }
\\\\\\
a=\cfrac{5}{\sqrt{3}}\cdot \cfrac{\sqrt{3}}{\sqrt{3}}\implies a=\cfrac{5\sqrt{3}}{\sqrt{3^2}}\implies a=\cfrac{5\sqrt{3}}{3}
