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
Answer:
you should choose the Roth IRA
Explanation:
we have to calculate after tax return in order to determine which option is better:
- traditional IRA account: after tax return = $2,500,000 x (1 - 30%) = $1,750,000
- Roth IRA account: after tax return = $2,000,000, since Roth IRA's distributions are tax free
Roth IRA contributions are not tax deductible, that is why their distributions are tax free. While traditional IRA contributions are tax deductible, that is why their distributions are taxed at marginal tax rate.
The double surplus of worldwide stability of payments leads to the excessive boom of foreign exchange reserves.
Due to the fact region II runs trade (and perhaps funding income) and cutting-edge account surpluses, it's miles in the section of the young creditor kingdom. Combining the 2 areas as an entire, China runs “dual surpluses”—with a $50 billion USD contemporary account surplus, and a $100 billion USD capital account surplus, respectively.
Some of the explanatory factors for this surplus relate to the health crisis. The pandemic has caused a distortion in global demand away from leisure, tourism, and commodities, which China imports in huge quantities, toward clinical merchandise, IT, and domestic equipment, which China exports.
Furthermore, China's goods alternate surplus, the biggest contributing element to the modern-day account surplus, has long been sustained by using processing alternate which imports additives to make finished products for exports.
