Sn = n/2 (a1+an)
= 8/2 (3-38)
= 4 (-35)
= -140
A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
Answer : The rate of depreciation is, $16000
Step-by-step explanation :
Formula used to calculate the rate of depreciation is:
![\text{Depreciation rate}=\frac{\text{Purchase price of asset }+\text{ Salvage value}}{\text{Estimate life of asset}}](https://tex.z-dn.net/?f=%5Ctext%7BDepreciation%20rate%7D%3D%5Cfrac%7B%5Ctext%7BPurchase%20price%20of%20asset%20%7D%2B%5Ctext%7B%20Salvage%20value%7D%7D%7B%5Ctext%7BEstimate%20life%20of%20asset%7D%7D)
Given:
Purchase price of asset = $15000
Salvage value = $7000
Estimate life asset = 3 years
Now put all the given values in the above formula, we get:
![\text{Depreciation rate}=\frac{15000+7000}{5}](https://tex.z-dn.net/?f=%5Ctext%7BDepreciation%20rate%7D%3D%5Cfrac%7B15000%2B7000%7D%7B5%7D)
Deprecation rate = $16000
Therefore, the rate of depreciation is, $16000
