Determine whether set of values represents an inverse variation. If yes, identify the constant of variation and write an inverse

Natasha_Volkova [10]

SOLUTION

If the table represents an inverse variation, it means that y is inversely proportional to x, written as

$\begin{gathered} y\propto\frac{1}{x} \\ \propto is\text{ a sign of proportionality } \end{gathered}$

Removing the proportionality sign and introducing a constant k, we have

$\begin{gathered} y=k\times\frac{1}{x} \\ y=\frac{k}{x} \end{gathered}$

In the first column, we have x = -4 and y = 3.5. Substituting these values for x and y, we have

$\begin{gathered} y=\frac{k}{x} \\ 3.5=\frac{k}{-4} \\ k=3.5\times-4 \\ k=-14 \end{gathered}$

So, if it's an inverse variation, the relationship would be

$y=\frac{-14}{x}$

In the second column, x = -2 and y = 7.

Now lets substitute the value of x for -2. If we get y to be 7, then the relationship is an inverse variation

We have

$\begin{gathered} y=\frac{-14}{x} \\ y=\frac{-14}{-2} \\ y=7 \end{gathered}$

Since we got y = 7, the relationship is therefore an inverse variation.

The constant k = -14

The equation for the inverse variation is

$y=\frac{-14}{x}$

find the measure of each angle acute angle in a right triangle where the measure of one acute angle is twice the difference of t

Marina86 [1]

Answer:

The measures of the acute angles are 38 and 52 degrees.

Step-by-step explanation:

In a right triangle, there are three angles, a right angle and two acute angles. In every traingle, the sum of the measures of the angles is 180 degrees. Let's call the acute angles $a$ and $b$ .

$a + b +90 = 180$

The problem also says that one angle is twice the difference of the other angle and 12. That would look like this:

$a = 2(b-12)$

Now we have two equations. If we simplify them, we get these:

$\left \{ {{a=90-b} \atop {a=2b-24}} \right.$

Now you can substitute $a$ in the first equation for $a$ in the second equation

$90-b=2b-24$

Add $b$ to both sides of the equation

$90 = 3b-24$

Add $24$ to both sides

$114 = 3b$

Divide both sides by 3

$38 = b$

Now, you can substitute $38$ for $b$ in the first equation and simplify.

$a = 90-38$

$a=52$

Therefore,

$a=52$ , and $b=38$
