Answer: ≈ 5.2

Step-by-step explanation:

You're gonna want to use the Law of Cosines to solve:

c² = a² + b² -2abcos(R)

c² = 6² + 9² - 2(6)(9)cos(34°)

c² = 36 + 81 - 108cos(34°)

c² = 117 - 108(.82904)

c² = 27.46368

√c² = √27.46368 => 5.2405 = 5.2

If g(x)=4x-6 then g^-1(x)=?<br> (1) -4x+6<br> (2)-1/4x+1/6<br> (3)1/4x+3/2<br> (4)1/4x+6

kati45 [8]

Given:

$g(x)=4x-6$

To find:

The function $g^{-1}(x)$ .

Solution:

we have,

$g(x)=4x-6$

Put g(x)=y.

$y=4x-6$

Interchange x and y.

$x=4y-6$

Isolate y.

$x+6=4y$

$\dfrac{x+6}{4}=y$

$y=\dfrac{x+6}{4}$

Substitute $y=g^{-1}(x)$ .

$g^{-1}(x)=\dfrac{x+6}{4}$

$g^{-1}(x)=\dfrac{x}{4}+\dfrac{6}{4}$

$g^{-1}(x)=\dfrac{x}{4}+\dfrac{3}{2}$

Therefore, the correct option is (3).
