Using the future value formula: \(FV = PV \times (1+r)^n\). So \(1000 = 250\times(1+r)^{16}\). \((1+r)^{16} = 4\). \(1+r = 4^{1/16} = 4^{0.0625}\). \(\ln(1+r) = \frac{\ln 4}{16} = \frac{1.386}{16} = 0.0866\). \(1+r = e^{0.0866} \approx 1.0905\). So \(r \approx 9\%\). Wait: \(4^{1/16}\): \(\log(4)/16 = 0.602/16=0.0376\), antilog \(=1.089\), so \(r\approx 9\%\) = option (B). Re-examining: \(4^{0.0625}=1.0905\Rightarrow r\approx9\%\). Answer: option (B) = 9 percent.

Find the intercepts of $3x - 2y = 0$:

x-intercept (set $y = 0$): $3x = 0 \Rightarrow x = 0$.

y-intercept (set $x = 0$): $-2y = 0 \Rightarrow y = 0$.

Both intercepts are $0$ (the line passes through the origin).

Quantity A $= 0 =$ Quantity B. The two quantities are equal.

This reveals that financial markets often prioritize short-term cost reduction (immediate expense savings from layoffs) over long-term human capital development, even though chronic job insecurity causes stress and can lower performance and productivity.

Alcoholic KOH (strong base in ethanol) promotes E2 elimination to form alkenes. Aqueous KOH favors substitution; conc. H₂SO₄ can cause elimination but also other reactions; Zn dust is for dehalogenation (vicinal dihalides).

Using Hooke's Law: $l = L + \frac{TL}{AY} \implies l = L + kT$ where $k = \frac{L}{AY}$.

• $l_1 = L + kT_1$ and $l_2 = L + kT_2$
• Subtracting: $l_2 - l_1 = k(T_2 - T_1) \implies k = \frac{l_2 - l_1}{T_2 - T_1}$
• Substitute $k$ back: $L = l_1 - T_1(\frac{l_2 - l_1}{T_2 - T_1}) = \frac{T_2 l_1 - T_1 l_2}{T_2 - T_1}$.

Midpoint: distance from each charge = d. Potential = k(5μ)/d + k(-5μ)/d = 0.

The textbook distinguishes between different departments within a newspaper's business section:

• Advertising Department: Generates revenue by selling classified and display advertising space; fixes rates for different types and positions of ads
• Circulation Department: Its primary goal is to increase the publication's circulation (readership). Higher circulation: (a) directly generates subscription revenue, and (b) allows the newspaper to charge higher advertising rates (more readers = more valuable advertising space) and (c) gives the newspaper greater prestige and editorial influence. The textbook notes: “It is always a pride for a publication to note its high circulation.”
• Accounts Department: Manages salaries, purchases, transport, and audit reports

Note that the physical printing and delivery of newspapers is handled by the Technical/Press Department, not the circulation department.
