State two essential conditions for rusting of iron. List two methods of protecting iron from rusting?

deff fn [24]

<h3>- - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - </h3>

➷ The presence of Oxygen and the presence of slightly acidic water are essentials for rusting of Iron. To protect Iron from rusting, 'grease coating' can be used. This stops the oxygen and water from being able to make direct contact with the Iron. Also, galvanization can be tried. This is where the Iron is coated in a protective zinc coating to prevent it from rusting.

➶ Good Luck (:

Determine the location and values of the absolute maximum and absolute minimum of given function: f(x)= ( -x+2)^4, Where 0<=x

jeyben [28]

Answer:

The absolute maximum and the absolute minimum are (0, 16) and (2, 0).

Step-by-step explanation:

First, we obtain the first and second derivatives of the function by chain rule and derivative for a power function, that is:

First derivative

$f'(x) = -4\cdot (-x+2)^{3}$

Second derivative

$f''(x) = 12\cdot (-x + 2)^{2}$

Then, we proceed to do the First and Second Derivative Tests:

First Derivative Test

$-4\cdot (-x+2)^{3} = 0$

$-x + 2 = 0$

$x = 2$

Second Derivative Test

$f''(2) = 12\cdot (-2+2)^{2}$

$f''(2) = 0$

The Second Derivative Test is unable to determine the nature of the critical values.

Then, we plot the function with the help of a graphing tool. The absolute maximum and the absolute minimum are (0, 16) and (2, 0).

A line that passes through the point (1, –1) and parallel to another line whose slope is 1.

Mars2501 [29]

Parallel lines have same slope so so far the new equation looks like this
$y = 1x + b \\ y = mx + b$
now you plug in you points or coordinates to find b or solve for the y-intercept
$- 1 = 1(1) + b$
$- 1 = 1 + b$
$- 1 = 1 + b \\ - 1 = - 1$
$- 2 = b$
now that you have your b your final solution is
$y = 1x - 2 \: or \: y = x - 2$
