Calculate WACC using book values: The weight of debt is calculated by adding the current portion of long-term debt‚ notes payable and long-term debt‚ and dividing it by the sum of debt and equity. $5.4 + 855.3 + 435.9 = $1‚296.6 $1‚296.6 / (1‚296.6 + 3‚494.5) = .27 = 27% The weight of equity is calculated by dividing the total shareholder equity by the sum of debt and equity. $3‚494.5 / (1‚296.6 + 3‚494.5) = .73 = 73% Cost of Debt To find the cost of debt I subtracted the tax savings from

The Vector equation of a plane To find the vector equation of a plane a point on the plane and two different direction vectors are required. The equation is defined as: where a is the point on the plane and b and c are the vectors. This equation can then be written as: The Cartesian equation of a plane The cartesian equation of the plane is easier to use. The equation is defined as: One of the advantages to writing the equation in cartesian form is that we can easily find the normal
