Answer:

\dfrac{y^2}{36}-\dfrac{x^2}{16}=1

Step-by-step explanation:

<u>Standard form equation of a vertical hyperbola</u>

\dfrac{(y-k)^2}{a^2}-\dfrac{(x-h)^2}{b^2}=1

where:

  • center = (h, k)
  • vertices = (h, k±a)
  • co-vertices = (h±b, k)
  • foci = (h, k±c) where c² = a² + b²
  • \textsf{asymptotes}: \quad y =k \pm \left(\dfrac{a}{b}\right)(x-h)
  • Transverse axis: x = h
  • Conjugate axis: y = k

From inspection of the graph:

  • center = (0, 0)  ⇒ h = 0, k = 0
  • vertices = (0, 6) and (0, -6)  ⇒  a = 6
  • co-vertices = (4, 0) and (-4, 0)  ⇒  b = 4

Substitute the found values into the formula:

\implies \dfrac{(y-0)^2}{6^2}-\dfrac{(x-0)^2}{4^2}=1

\implies \dfrac{y^2}{36}-\dfrac{x^2}{16}=1

{\qquad\qquad\huge\underline{{\sf Answer}}}

The given figure shows a vertical hyperbola with its centre at origin, and as we observe the figure, we can conclude that :

Length of transverse axis is :

\qquad \sf  \dashrightarrow \: 2b = 12

\qquad \sf  \dashrightarrow \: b = 6

length of conjugate axis is :

\qquad \sf  \dashrightarrow \: 2a = 8

\qquad \sf  \dashrightarrow \: a = 4

Equation of hyperbola ~

\qquad \sf  \dashrightarrow \:    \cfrac{ {y}^{2} }{ {b}^{2} } - \cfrac{  {x}^{2} }{ {a}^{2} }  = 1

plug in the values ~

\qquad \sf  \dashrightarrow \:    \cfrac{ {y}^{2} }{ {6}^{2} } - \cfrac{  {x}^{2} }{ {4}^{2} }  = 1

\qquad \sf  \dashrightarrow \:    \cfrac{ {y}^{2} }{ {36}^{} } - \cfrac{  {x}^{2} }{ {16}^{} }  = 1

7. f(x) = Square root of quantity x plus nine. ; g(x) = 8x - 13 Find f(g(x)). (1 point) f(g(x)) = 2 Square root of quantity two
AlladinOne [14]

Answer:

f(g(x)) =

\sqrt{8x \:  -  \: 13}  \:  +  \: 9

Step-by-step explanation:

f(x) =

\sqrt{x}  \:  +  \: 9

g(x) = 8x - 13

f(g(x) =

\sqrt{8x \:  - 13}  \:  +  \: 9

30 PTS!!! ANYONE GOOD AT MATH PLS HELP!
siniylev [52]

Answer:

\frac{2}{\sqrt{5} }

Step-by-step explanation:

To solve this, all we need to do is draw a triangle.  

From the arctan(2) we can deduce that tan(x)=\frac{2}{1}

From that, we can draw our triangle as we know that tan(x) is the opposite side over the adjacent side. Attached is that triangle. Through the Pythagorean Theorem, we can find that the hypotenuse of this right triangle is  \sqrt{5}

Now all we need to do is take the sin of this triangle, which is the opposite side over the hypotenuse

This gives us the value of \frac{2}{\sqrt{5} } which is our answer.

Solve #3 Find the length of the missing side.a) A right triangle has a side length 2.4 cm and 6.5 cm. What is the length of the
Snezhnost [94]

Answer:

A) ≈ 6.93

B) ≈ 0.02

Step-by-step explanation:

A)

Formula : a² + b² = c²

2.4² + 6.5² = c²

5.76 + 42.25 = c²

c = √48.01

c ≈ 6.93

B)

Formula = c² - a² = b²

1/3² - 1/4² = b²

1/9 - 1/16 = b²

b = √7/144

b ≈ 0.02
