What is the inverse of the function f(x)=x/5-2

umka2103 [35]

Answer:

$\huge\boxed{\sf f^{-1}(x)=5x+10}$

Step-by-step explanation:

<h3>Given function:</h3>

$\displaystyle f(x)=\frac{x}{5} -2$

Put f(x) = y

$\displaystyle y=\frac{x}{5} -2$

Swap x and y

$\displaystyle x = \frac{y}{5} -2$

Now, solve for y

$\displaystyle x = \frac{y}{5} -2$

Add 2 to both sides

$\displaystyle x + 2 =\frac{y}{5}$

Multiply 5 to both sides

$5(x+2)=y$

Distribute

$5x + 10 =y$

Put y = f⁻¹(x)

$\boxed{f^{-1}(x)=5x+10}$

$\rule[225]{225}{2}$

Answer:

5 units

Step-by-step explanation:

I used the pythagorean theorem (a^2 + b^2 = c^2) to find the answer. I put 3 in a and 4 in b. I squared them and got 9 + 16 = 25. I found the square root of 25 which is 5 and that is my answer.

Trigonometry

Rainbow [258]

Answer:

144°

Step-by-step explanation:

We are asked to convert 4π/5 radians to degrees.

#We know that:

$1 \ rad= 57.296\textdegree =180/\pi$

Therefore, we multiply 4π/5 radians by 180/π to get its degrees equivalent:

$=\frac{4\pi}{5}\ rad\times \frac{180}{\pi}\\\\=144\textdegree$

Hence, the degrees equivalent of 4π/5 rad is 144°.
