You would like to evlauate pursuing a new computing tool for your team. The new workstation would impact 10 of your campany staff and cost about $5,500. You expect the new work stations to have a yearly maintenance and operation cost of 20% of the initial cost. At the end of the 3 year life cycle you think the new workstation can have a salvage value of 5% of the initial cost. What is the present worth of the new stations if you use an internal MARR of 17%

-7,759.29 dollar

Explanation:

cost of maintenance and operation

initial cost of $5500 x 20%

= 1100 Dollars

salvage value

initial cost of $5500 x 5%

= $275

pw = -5500-1100(p/a,17%,3) +275(p/f,17%,3)

pw = -5500-(1100*2.21) + (275*0.6244)

pw = -5500-2431+17.71

= -7759.29

so pw, that is present worth of new stations using internal MARR of 17% is -7759.29 dollars

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
