What happens to a 44-degree angle if you rotate it 90 degrees counterclockwise? Explain your answer.

Answer:

it would melt

Step-by-step explanation:

at 40 degrees, the angle will stay in its natural shape. if increased to 90 degrees on the counter, and with the wisdom of mr. clock, the angle will start to warp, and lose its shape. evidently, if the angle is heated at a steady 90 degrees, the melting process will occur, and it will make a mess on your counter. thats why, when melting angles, I recommend putting it in a container, so as to not make too big of a mess.

Q1 : Find the inverse of the function.

Mamont248 [21]

Answer:

1. Option D is correct.

2. Option B is correct.

3. Option B is correct.

Step-by-step explanation:

Inverse function defined as the the function that undergoes the action of the other function.

A function $f^{-1}$ is the inverse of f if whenever y =f(x) and $x =f^{-1}$

To find the inverse of the function:

Q1.

Given the function: f(x) = 7x -1

Put y for f(x) and solve for x;

y= 7x -1

Add 1 both sides we get;

y + 1 = 7x

Divide both sides by 7 we get;

$x = \frac{y+1}{7}$

Put $f^{-1}(y)$ for x;

$f^{-1}(y) = \frac{y+1}{7}$

Interchange y =x, we have

$f^{-1}(x) = \frac{x+1}{7}$

Q 2.

Given the function:

$f(x) = x^3 - 7$

Put y for f(x) and solve for x;

$y = x^3-7$

Add 7 both sides we get;

$y + 7 =x^3$

taking cube root both sides we get

$x =\sqrt[3]{y+7}$

Put $f^{-1}(y)$ for x;

$f^{-1}(y) =\sqrt[3]{y+7}$

Interchange y =x, we have

$f^{-1}(x) = \sqrt[3]{x+7}$

Q3 .

Given the function:

$f(x) = 5x^3 - 3$

Put y for f(x) and solve for x;

$y = 5x^3-3$

Add 3 both sides we get;

$y + 3 =5x^3$

Divide both sides by 5 we get;

$x^3 = \frac{y+3}{5}$

taking cube root both sides we get

$x = \sqrt[3]{\frac{y+3}{5} }$

Put $f^{-1}(y)$ for x;

$f^{-1}(y) = \sqrt[3]{\frac{y+3}{5} }$

Interchange y =x, we have

$f^{-1}(x) = \sqrt[3]{\frac{x+3}{5} }$
