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
I am going to say (C) That seems like the most obvious answer to me.
Answer:
$0
Explanation:
Profits will be $0 if sales turn out to be $3.2 million.
Profit will decrease by ($0.20) million.
Degree of operating leverage = change in operating income ÷ change in sales
![5=\frac{[\frac{EBIT1-0.20}{0.20}]}{\frac{3.2-4}{4} }](https://tex.z-dn.net/?f=5%3D%5Cfrac%7B%5B%5Cfrac%7BEBIT1-0.20%7D%7B0.20%7D%5D%7D%7B%5Cfrac%7B3.2-4%7D%7B4%7D%20%7D)
(EBIT1 - 0.20) ÷ 0.20 = -1
(EBIT1 - 0.20) = -0.2
EBIT 1 = 0
Therefore,
Profits = $0

Answer:
C. A trial balance presents data in debit and credit format.
