Ace Company purchased a machine valued at $310,000 on August 1. The equipment has an estimated useful life of six years or 2.5 million units. The equipment is estimated to have a salvage value of $7,200. Assuming the straight-line method of depreciation, what is the amount of depreciation expense that needs to be recorded at the end of the first year

The amount of depreciation at the end of the first year = $21027.77

Explanation:

Given machine cost = $310000

The life of machine = 6 years

Salvage  value = $7200

Now find the total depreciation by subtracting the salvage value from the cost of the machine.

Depreciation = Machine cost – salvage value

= 310000 – 7200

= 302800

Total depreciation of 6 years = $302800

Annual depreciation = 302800 / 6 = 50466.66

Since in the first year the machine is used from 1st August to 31st December. So, depreciation = 50466.66 *(5/12) = 21027.77

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.
