First we need to put it in slope intercept form (solve for y). Then we get tex]y= -\frac{2}{3} x+490[/tex]. So the slope is-2/3 and the y intercept is 490.

Solve 73 make sure to also define the limits in the parts a and b
Aleks04 [339]

73.

f(x)=\frac{3x^4+3x^3-36x^2}{x^4-25x^2+144}

a)

\lim_{x\to\infty}f(x)=\lim_{x\to\infty}(\frac{3+\frac{3}{x}-\frac{36}{x^2}}{1-\frac{25}{x^2}+\frac{144}{x^4}})=3\lim_{x\to-\infty}f(x)=\lim_{x\to-\infty}(\frac{3+\frac{3}{x}-\frac{36}{x^2}}{1-\frac{25}{x^2}+\frac{144}{x^4}})=3\cdot\frac{1}{2}=3

b)

Since we can't divide by zero, we need to find when:

x^4-2x^2+144=0

But before, we can factor the numerator and the denominator:

\begin{gathered} \frac{3x^2(x^2+x-12)}{x^4-25x^2+144}=\frac{3x^2((x+4)(x-3))}{(x-3)(x-3)(x+4)(x+4)} \\ so: \\ \frac{3x^2}{(x+3)(x-4)} \end{gathered}

Now, we can conclude that the vertical asymptotes are located at:

\begin{gathered} (x+3)(x-4)=0 \\ so: \\ x=-3 \\ x=4 \end{gathered}

so, for x = -3:

\lim_{x\to-3^-}f(x)=\lim_{x\to-3^-}-\frac{162}{x^4-25x^2+144}=-162(-\infty)=\infty\lim_{x\to-3^+}f(x)=\lim_{x\to-3^+}-\frac{162}{x^4-25x^2+144}=-162(\infty)=-\infty

For x = 4:

\lim_{x\to4^-}f(x)=\lim_{n\to4^-}\frac{384}{x^4-25x^2+144}=384(-\infty)=-\infty\lim_{x\to4^-}f(x)=\lim_{n\to4^-}\frac{384}{x^4-25x^2+144}=384(-\infty)=-\infty

The triangles below are similar. Triangle S R P. Angle S is 54 degrees, R is 41 degrees, P is 85 degrees. Triangle X Y Z. Angle
rewona [7]

Answer:

The similarity statements that describes the relationship between the two triangles are

Triangle S R P is similar to triangle X Z Y.

Triangle R S P is similar to triangle Z X Y.

Triangle R P S is similar to triangle Z Y X.

Step-by-step explanation:

Given:

Triangles below are similar,

In ΔSRP

∠S = 54 ° , ∠R = 41° , ∠P = 85°

In ΔXYZ

∠X = 54 ° , ∠Z = 41° , ∠Y = 85°

Solution:

If two triangles are similar then their corresponding angles are Equal.

When the two triangles are Similar then their Vertices are correspondence to each other. the correspondence of vertices are as

For, Δ SRP ~ Δ XZY

S ↔ X        ∠S ≅ ∠X = 54°

R ↔ Z        ∠R ≅ ∠Z = 41°

P ↔ Y        ∠P ≅ ∠Y = 85°

The true statement  

Triangle S R P is similar to triangle X Z Y.

Triangle R S P is similar to triangle Z X Y.

Triangle R P S is similar to triangle Z Y X.

  • Triangle P R S is similar to triangle X Y Z,

Not correct it should be

Triangle P R S is similar to triangle Y Z X,

  • Triangle P S R is similar to Triangle Z Y X

Not correct it should be

Triangle P S R is similar to Triangle Y X Z.

  • Triangle S P R is similar to triangle X Z Y

Not correct it should be

Triangle S P R is similar to triangle X Y Z
