Mathematics
1 answer:
Keith_Richards [23]3 years ago
6 0
Second moment of area about an axis along any diameter in the plane of the cross section (i.e. x-x, y-y) is each equal to (1/4)pi r^4.
The second moment of area about the zz-axis (along the axis of the cylinder) is the sum of the two, namely (1/2)pi r^4.

The derivation is by integration of the following:
int int y^2 dA
over the area of the cross section, and can be found in any book on mechanics of materials.

Gnom [1K]

Based on the EBIT, the cost of equity, and rates attached, Calvert Corporation has the following values:

  • a. $124,019.61
  • b. - 1 $136,421.57
  • b - 2 $155,024.51
<h3 /><h3>What is the value of Calvert Corporation?</h3>

This can be found as:

=  EBIT x (1 - tax rate) / cost of an equity

= 25,300 x (1 - 25%) / 0.153

= $124,019.61

<h3>What is the value with 40% debt?</h3>

= Value of firm + (Tax rate x Debt percentage x Value of firm)

= 124,019.61 + (25% x 40% x 124,019.61)

= $136,421.57

<h3>What is the value with 100% debt?</h3>

= 124,019.61 + (25% x 100% x 124,019.61)

= $155,024.51

Melanies blue notebook cover is 20 centimeters by 30 centimeters. She has a sticker for each letter in her name. Each sticker is
gizmo_the_mogwai [7]
Find the surface area of her notebook.

30 + 30 + 20 + 20 = 100

Now find the surface area of the square stickers.

2 + 2 + 2 + 2 = 8

So this is the surface area of one square, now multiply it by 8.

8 * 7 = 56

This is the surface area of all the stickers, now subtract it to the surface area of the notebook:

100 - 56 = 44

So 44 centimeters of the notebook cover will still be showing.
