Due to the properties of a Isosceles trapezoid, \overline{WY} =\overline{ZX}.
Therefore, 8a - 3 = 19 since \overline{WY} = 8a - 3 and \overline{ZX} = 19.

8a - 3 = 19
8a = 22
a = 2.75

Alik [6]

Answer:The value of the bulldozer after 3 years is $121950

Step-by-step explanation:

We would apply the straight line depreciation method. In this method, the value of the asset(bulldozer) is reduced linearly over its useful life until it reaches its salvage value. The formula is expressed as

Annual depreciation expense =

(Cost of the asset - salvage value)/useful life of the asset.

From the given information,

Useful life = 23 years

Salvage value of the bulldozer = $14950

Cost of the new bulldozer is $138000

Therefore

Annual depreciation = (138000 - 14950)/ 23 = $5350

The value of the bulldozer at any point would be V. Therefore

5350 = (138000 - V)/ t

5350t = 138000 - V

V = 138000 - 5350t

The value of the bulldozer after 3 years would be

V = 138000 - 5350×3 = $121950

vichka [17]

Answer:

x = ± 2i

Step-by-step explanation:

The equation has no real roots, gut has complex roots

Given

x² = - 4 ( take the square root of both sides )

x = ± \sqrt{-4}

  = ± \sqrt{4(-1)}

[ Note that \sqrt{-1} = i ]

  = ± \sqrt{4} × \sqrt{-1} = ± 2i
