For this case we have to:

Let "a" be the side of the square. Then, the area "A", will be given by:

$A = a * a = a ^ 2$

Also, by the Pythagorean theorem we have to:

$x ^ 2 = a ^ 2 + a ^ 2\\x ^ 2 = 2a ^ 2\\\frac {x ^ 2} {2} = a ^ 2$

Finally the area is:

$A = \frac {x ^ 2} {2}$

Answer:

Option A

How many times as large is the approximate radius of mercury atom, 1.5 x 10 meter, as the approximate radius of a hydrogen atom,

Verdich [7]

The correct question is
<span>how many times as large is the approximate radius of a mercury atom, 1.50*10^-11 meter, as the approximate radius of a hydrogen atom, 2.5*10^-11
</span>
Since both are conveniently --------> *10^-11
<span>we can just divide 2.5 by 1.5

</span>2.5/1.5-------> 1.6666
<span>So a hydrogen atom is 1.67 times larger than a mercury atom</span>

Answer:

Switch x and y, and solve for y

$f^{-1}(x) =\frac{(x -4)^3}{8}$

Step-by-step explanation:

Given

$f(x) = 3\sqrt{8x} + 4$

Required

Complete the steps to determine the inverse function

Solving (a): Complete the blanks

Switch x and y, and solve for y

Solving (b): Determine the inverse function

$f(x) = \sqrt[3]{8x} + 4$

Replace f(x) with y

$y = \sqrt[3]{8x} + 4$

Switch x and y

$x = \sqrt[3]{8y} + 4$

<u>Now, we solve for y</u>

Subtract 4 from both sides

$x -4= \sqrt[3]{8y} + 4-4$

$x -4= \sqrt[3]{8y}$

Take cube roots of both sides

$(x -4)^3= 8y$

Divide both sides by 8

$\frac{(x -4)^3}{8} = y$

So, we have:

$y =\frac{(x -4)^3}{8}$

Hence, the inverse function is:

$f^{-1}(x) =\frac{(x -4)^3}{8}$
