Imagine a machine that you put number into. However, the machine has a function that creates a new number. Remember that the number that comes out depends on the number that is put in. With this information, i'm pretty sure its the third bubble. im sorry that my information might not be accurate.

I need help rlly bad I have no idea what’s the answer plsss help me!!!

Answer:

n = 6\sqrt{3}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{\sqrt{3} }{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{n}{12} = \frac{\sqrt{3} }{2} ( cross- multiply )

2n = 12\sqrt{3} ( divide both sides by 2 )

n = 6\sqrt{3}

Consider the function.
Licemer1 [7]

Answer:

Option 4

Step-by-step explanation:

Given function is,

f(x)=2\frac{1}{2}-3\frac{1}{3}x

Steps to get the inverse of the given function,

Step 1,

Convert the function into equation,

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

Step 2,

Interchange the variables 'x' and 'y',

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

Step 3,

Solve the equation for the value of y,

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

x-\frac{5}{2}=-\frac{10}{3}y

-x+\frac{5}{2}=\frac{10}{3}y

-3x+\frac{15}{2}=10y

-\frac{3}{10}x+\frac{15}{20}=y

y=-\frac{3}{10}x+\frac{3}{4}

Step 4,

Convert the equation into inverse function,

f^{-1}x=-\frac{3}{10}x+\frac{3}{4}

For x-intercepts,

Substitute y = 0,

0=-\frac{3}{10}x+\frac{3}{4}

\frac{3}{10}x=\frac{3}{4}

x=\frac{10}{4}

x=\frac{5}{2}

x=2\frac{1}{2}

Therefore, x-intercept of the inverse function is (2\frac{1}{2},0).

Option 4 will be the answer.
