Please help me with pythagoras.
lana [24]

Answer:

(q)

cb \:  =  \sqrt{4 {}^{2}  +  {3}^{2} }

cb = 5

q =  \sqrt{ {13}^{2}  -  {5}^{2} }

q = 12

(r)

cb = \sqrt{ {13}^{2} -  {5}^{2}  }

cb = 12

r =  \sqrt{12 {}^{2} - 5 {}^{2}  }

r =  \sqrt{119}

r = 10.91

(s)

ab =  \sqrt{20 {}^{2}  - 16 {}^{2} }

ab = 12

s =  \sqrt{12 {}^{2} + 8 {}^{2}  }

s = 4 \sqrt{13}

s = 14.42

★ Oblique Asymptote ★

f(x) =  \frac{x {}^{2}  + 5x + 6}{x - 4} \\ f(x) = (x - 4)(x + 9) + 42 \\
Hence , oblique Asymptote is obtained simultaneously by the Quotient of the function obtained ,
HENCE , oblique Asymptote is

What is the Inverse Equation<br><br>f(x) =6x-1 ?? please I need help!​
Scrat [10]

Answer:

f^{-1}(x)=\frac{x+1}{6}

Step-by-step explanation:

So we have the function:

f(x)=6x-1

To find the inverse function, switch x and f(x), change f(x) to f⁻¹(x), and solve for f⁻¹(x). Therefore:

f(x)=6x-1

Switch:

x=6f^{-1}(x)-1

Add 1 to both sides:

x+1=6f^{-1}(x)

Divide both sides by 6:

f^{-1}(x)=\frac{x+1}{6}

And that's our answer :)
