Answer:
Average yearly depreciation of the car is $291.67
Step-by-step explanation:
Cost of the used car = $3000
Trade in value of the car is given as $1250.
Duration for which the car was used = 6 years
Total depreciation in the price of the car = Cost of the car - price of the car at which car is being traded
So total depreciation = 3000 - 1250 = $1750
Average yearly depreciation = Total depreciation ÷ Years driven
Average depreciation =
Therefore average yearly depreciation $291.67 is the answer.
Answer:
b)0, yes
Step-by-step explanation:
Given:
Vectors (4,8) . (6,-3)
Finding inner product of vectors:
= 4x6 + 8x-3
=24-24
=0
Now to check the angle between them using formula a.b=|a|.|b|cosθ
|a|=
=8.9
|b|=
=6.7
Putting values of a.b=0 and |a|=8.9, |b|=6.7 in a.b=|a|.|b|cosθ we get,
0= 8.9(6.7)cosθ
cosθ =0
θ=90 degrees
Hence the two vectors are perpendicular !
