Which equation is the inverse of y = 9x2 – 4? y = StartFraction plus-or-minus StartRoot x + 4 EndRoot Over 9 EndFraction y = plu

andre [41]

Option C: $y=\pm\frac{\sqrt{x+4}}{3}$ is the inverse of the function

Explanation:

The given function is $y=9 x^{2}-4$

We need to determine the inverse of the function.

To determine the inverse of the function, we need to interchange the values of x and y and solve for y.

Let us interchange the variables x and y in the function $y=9 x^{2}-4$ , we have,

$x=9 y^{2}-4$

Adding both sides of the equation by 4, we have,

$x+4=9 y^{2}$

Dividing both sides of the equation by 9, we have,

$\frac{x+4}{9} =y^2$

Switch sides, we have,

$y^2=\frac{x+4}{9}$

Taking square root on both sides of the equation, we have,

$y=\pm\frac{\sqrt{x+4}}{3}$

Thus, the inverse of the function is $y=\pm\frac{\sqrt{x+4}}{3}$

Therefore, Option C is the correct answer.

The word geometry has eight letters. three letters are chosen at random. what is the probability that two consonants and one vow

olga nikolaevna [1]

Answer:

0.536 is the required probability.

Step-by-step explanation:

We have been given the word the word "GEOMETRY"

we have to find the probability that two consonants and one vowel are chosen:

Number of consonants are: 5

Number of vowels are: 3

Hence, The required probability is: $\frac{^5C_2\cdot ^3C_1}{^8C_3}$

Using: $^nC_r=\frac{n!}{(r!)(n-r)!}$

$\frac{\frac{5!}{3!\cdot 2!}\cdot\frac{3!}{1!\cdot 2!}}{\frac{8!}{3!\cdot 5!}}$

Simplifying the above expression:

$\frac{\frac{5\cdot 4\cdot 3!}{3!\cdot 2}\cdot {\frac{3\cdot 2!}{2!}}}{\frac{8\cdot 7\cdot 6\cdot 5!}{5!\cdot 3\cdot 2}}$

Further simplification after cancelling out the common terms we get:

$\Rightarrow \frac{30}{56}=\frac{15}{28}=0.5357=0.536$

Hence, Option 1 is correct.
