What is $65.04 times 12 ?

$b)\\\\y=0\\x^2+0^2-8x+4*0+4=0\\x^2-8x+4=0\\a=1\ \ \ \ b=-8\ \ \ \ c=4\\D=(-8)^2-4*1*4\\D=64-14\\D=48\\\sqrt{D}=\sqrt{48} \\ \sqrt{D}=\sqrt{16*3} \\\sqrt{D}=\sqrt{4^2*3} \\\sqrt{D}=4\sqrt{3} \\\displaystyle\\x=\frac{-(-8)б4\sqrt{3} }{2*1} \\\\x=\frac{8б4\sqrt{3} }{2} \\x_1=4-2\sqrt{3} \\x_2=4+2\sqrt{3}$

$c)\\\\A(6,2\sqrt{3}-2)\\ (x-4)^2+(y+2)^2=4^2\\(6-4)^2+(2\sqrt{3} -2+2)^2=16\\2^2+(2\sqrt{3} )^2=16\\4+2^2*(\sqrt{3})^2=16\\ 4+4*3=16\\4+12=16\\16\equiv16$

$d)\\A(6,2\sqrt{3}-2)}\\\sqrt{3} x+3y=\\\sqrt{3}(6)+3(2\sqrt{3} -2)=\\ 6\sqrt{3}+6\sqrt{3} -6=\\ 12\sqrt{3}-6$

Use the information for the question below.

Zielflug [23.3K]

Answer:

The correct option is d. Project B.

Step-by-step explanation:

Note: See the attached excel file for the calculation of the Cumulative Cash Flows of Projects A and B.

Payback period refers to the number of time or period that is needed to recoup the amount of money spent a project. The

payback period rule states that when considering two or more projects, a project with the shortest payback period should be selected.

Payback period can be calculated as follows:

Payback period = Time before full recovery + (Unrecovered cost at start of the time of full recovery / Cash flow during the time of full recovery) ………………. (1)

Using the information in the excel file (in red color), equation (1) can be calculated for Project A and Project B as follows:

Project A payback period = 2 + ($1,000 / $3,000) = 2.33

Project B payback period = 2 + ($3,000 / $10,000) = 2.30

Since the payback period of Project B payback period which is 2.30 is lower than the Project A payback period of 2.33, Project B should be selected.

Therefore, the correct option is d. Project B.
