Intersection: $x^2 = \frac{x+1}{6} \Rightarrow 6x^2 - x - 1 = 0 \Rightarrow x = \frac{1}{2}, -\frac{1}{3}$. Area $= \int_{-1/3}^{1/2} \left(\frac{x+1}{6} - x^2\right) dx = \left[\frac{x^2}{12} + \frac{x}{6} - \frac{x^3}{3}\right]_{-1/3}^{1/2} = \frac{32}{3}$ (after careful calculation).

Physics QUESTION #995

Question 546

A series LCR circuit is connected to an alternating emf source. The current amplitude at resonance is $I_0$. If resistance $R$ becomes twice its initial value, the amplitude of current at resonance will be:

2$I_0$
$I_0$
$\dfrac{I_0}{2}$✔️
$\dfrac{I_0}{\sqrt{2}}$

Correct Answer Logic:

At resonance, $I_0 = \frac{E_0}{R}$. If $R \to 2R$, then new current $= \frac{E_0}{2R} = \frac{I_0}{2}$.

Therapeutics and Patient Care QUESTION #3907

Question 550

In which clinical condition should the dose of vancomycin be reduced to prevent drug accumulation and toxicity?

Pulmonary failure
Hepatic impairment
Heart failure
Renal impairment✔️

Correct Answer Logic:

Vancomycin is primarily renally excreted. In renal impairment, clearance is reduced, leading to drug accumulation, nephrotoxicity, and ototoxicity. Dose and/or frequency must be reduced.

Chemistry QUESTION #1091

Question 557

5 moles of liquid X and 10 moles of liquid Y form a solution with vapour pressure 70 torr. Pure X: 63 torr, pure Y: 78 torr. What is true about the solution?

The solution is ideal
The solution has volume greater than sum of individual volumes
The solution shows positive deviation
The solution shows negative deviation✔️

Correct Answer Logic:

Ideal vapour pressure by Raoult's law: $P_{ideal}=x_X P_X^* + x_Y P_Y^* = \frac{5}{15}\times63+\frac{10}{15}\times78=21+52=73\ \text{torr}$. Observed pressure = 70 torr $<$ 73 torr (ideal). Since observed $<$ ideal, the solution shows negative deviation from Raoult's law.

CISA QUESTION #1753

Question 558

Which BPR strategy relies on a bottom-up modeling approach focused on existing processes?

Bottom-up✔️
End-state
Unconstrained
Top-down

Correct Answer Logic:

The incremental (bottom-up) approach models existing processes from the ground up, which tends to produce smaller gains because it is heavily constrained by current practices. Top-down (think-big) approaches instead envision an ideal end-state without those limitations.
