Answer:
y=34x+2.625
y=34x+2.75
y=−34x+1.25
y=34x+1.25
y=−34x+2.75
Correct answer:
y=−34x+2.75
Step-by-step explanation:
Answer: X = 3t, Y =2 - t, Z =2
Step-by-step explanation: the plane
x + y + z =4has normal vector
M =<1,1,1> and the line
x = 1 + t, y = 2 − t, z = 2t has direction
v =<1, −1, 2>. So the vector
A= n × v
=<1, 1, 1> × <1, −1, 2>
=<2−(−1),1−2,−1−1>
=<3,−1,−2>
Use the depreciation formula.
![\sf p(1-r)^n](https://tex.z-dn.net/?f=%5Csf%20p%281-r%29%5En)
Where 'p' is the principal value, 'r' is the rate it depreciates, and 'n' is the time. Just plug in what we know:
![\sf 28000(1-0.0725)^5](https://tex.z-dn.net/?f=%5Csf%2028000%281-0.0725%29%5E5)
Simplify by subtracting:
![\sf 28000(0.9275)^5](https://tex.z-dn.net/?f=%5Csf%2028000%280.9275%29%5E5)
Simplify the exponent:
![\sf 28000(0.6864)](https://tex.z-dn.net/?f=%5Csf%2028000%280.6864%29)
