Answer:
v(t) = (2t + 1)i + 3t²j + 4t³k
r(t) = (t² + t)i + (t³ + 7)j + (t⁴ - 4)k
Explanation:
a(t) = 2i + 6tj + 12t²k
v(t) = ∫a(t)dt
= ∫(2i + 6tj + 12t²k)dt
= 2ti + (6t²/2)j + (12t³/3)k + c
= 2ti + 3t²j + 4t³k + c
v(0) = i
i = 0i + 0j + 0k + c
c = i
∴ v(t) = 2ti + 3t²j + 4t³k + i
v(t) = (2t + 1)i + 3t²j + 4t³k
r(t) = ∫ v(t)dt
= i ∫ (2t + 1)dt + 3j ∫ t²dt + 4k ∫ t³dt
= i (2t²/2 + t) + 3j(t³/3) + 4k(t⁴/4) + d
= i (t² + t) + jt³ + t⁴k + d
r(0) = 7j - 4k
0i + 0j + 0k + d = 7j - 4k
d = 7j - 4k
∴ r(t) = (t² + t)i + t³j + t⁴k + 7j - 4k
r(t) = (t² + t)i + (t³ + 7)j + (t⁴ - 4)k
Employers typically need workers with both content skills and transferable skills to fill given positions. Content skills, also known as technical, job-specific or vocational skills, include those that relate specifically to your line of work. Transferable skills are those which you can use in a variety of occupations.
Answer:
Price level may increase or decrease and output decreases.
Explanation:
The price level is determinated bu the money supply and demand. A single price, in this case oil, cannot determinate prices or we end up in a loop.
So this is insufficient information to determinate the price level.
While the income decrease at a worldwide level will make the output of the economy even lower.
The statement which accurately describes intergenerational mobility patterns among industrial countries is the positions of parents in stratification is transmitted.
Intergenerational social mobility refers to the relationship between the socioeconomic status of parents and the status children achieve as adults. In other words, mobility reflects the extent to which individuals move up and down the social ladder relative to their parents.
Intergenerational mobility occurs when social status changes from generation to generation. The change can be upward or downward. For example, his father worked in a factory while his son was being trained to become a lawyer or a doctor.
