If the measure of DEF is 65 what is the measure of DE. PLEASE HELP FAST
Wittaler [7]

EF is tangent to the circle we'll assume; otherwise there's no progress.


Call the center C. ECD is isosceles, formed from two radii and the chord.


Angle CED is complementary to DEF


CED = 90 - 65 = 25 degrees


CDE is congruent, isosceles triangle and all that: CDE=25


That leaves DCE=180-25-25=130 degrees


That's the measure of arc DE as well:


Answer: 130 degrees, choice A

State the domain and end behavior of each rational function. Identify all horizontal and vertical asymptotes on the
laila [671]

Answer:

Rational Functions

Step-by-step explanation:

1)

f(x) = - \frac{x + 6}{2x + 3}

• State the domain

X ∈ R : x \neq - \frac{3}{2}

• End Behaviour

x \rightarrow \infty , y \rightarrow -\frac{1}{2}

• Horizontal and Vertical

y= -\frac{1}{2} , x=-\frac{3}{2}

• Graphic (Annex)

2) f(x) =  \frac{3x − 6}{x}

• State the domain

X ∈ R : x \neq  0

• End Behaviour

x \rightarrow \infty , y \rightarrow 3

• Horizontal and Vertical

y= 0

• Graphic (Annex)

3) f(x) =  \frac{3}{x^2-25}

• State the domain

X ∈ R : x \neq  5.5

• End Behaviour

x \rightarrow +/-\infty , y \rightarrow 0

• Horizontal and Vertical

y= 0 , x=+/- 5

• Graphic (Annex)

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

• State the domain

X ∈ R : x \neq  (3,1)

• End Behaviour

x \rightarrow +/-\infty , y \rightarrow +/- 1

• Horizontal and Vertical

y= 1 , x= (-3,1)

• Graphic (Annex)

5) f(x) =  \frac{ x^2 − 5x − 4}{x + 1}

• State the domain

X ∈ R : x \neq  -1

• End Behaviour

x \rightarrow +/-\infty , y \rightarrow +/ \infty

• Horizontal and Vertical

y=none , x= -1

• Graphic (Annex)

6) f(x) = \frac{ 5x }{x^2 + 9 }

• State the domain

X ∈ R

• End Behaviour

x \rightarrow +/-\infty , y \rightarrow 0

• Horizontal and Vertical

y= 0 , x= none

• Graphic (Annex)
