Answer:
Justin bought his truck new for $32,000. Its value decreases 9.0% each year. Choose the letter for the best answer.
5. Which function represents the yearly value of Justin's truck?
A f(t) = 32,000(1 + 0.9)^t
B f(t) = 32,000(1 - 0.9)^t
C f(t) = 32,000(1 + 0.09)^t
<u>D f(t) = 32,000(1 - 0.09)^t
</u>
6. When will the value of Justin's truck fall below half of what he paid for it?
F In 6 years
<u>G In 8 years
</u>
H In 10 years
J In 12 years
Step-by-step explanation:
The answer to that problem si 6-25+2x
The original height of the plant is 20 inches, and each week for 4 weeks its height increases by 2h inches, so at the end of 4 weeks its height would be:
20 + 4(2h) = 20 + 8h
Now for the next two weeks the plant grows in height by h inches each week, so we need to add a further 2h inches to the equation. Thus the expression that shows the height of the plant after 6 weeks is:
20 + 8h + 2h = 20 + 10h, therefor A is the correct answer
Answer:
54.8 Nm
Step-by-step explanation:
Torque is the cross product of the radius vector and force vector:
τ = r × F
Another way to write it is the product of the radius and force magnitudes times the sine of the angle between the vectors.
τ = rF sin θ
Here, r = 0.366 meters and F = 155 Newtons. F is in the +y direction, and r is 15° below the +x axis, so the angle between the vectors is 90° − 15° = 75°.
τ = (0.366 m) (155 N) (sin 75°)
τ = 54.8 Nm
Answer: 1/5
Step-by-step explanation: You just subtract 4/5 from 1, or 5/5. And BOOM! you get 1/5.
