Question : If $g=(2-\sqrt{3})$, what will be the value of $\left(g^3-\frac{1}{g^3}\right)$?

Option 1: $-30 \sqrt{3}$

Option 2: 52

Option 3: $30 \sqrt{3}$

Option 4: –52

Team Careers360 22nd Jan, 2024

Correct Answer: $-30 \sqrt{3}$


Solution : Given, $g=(2-\sqrt{3})$
⇒, $\frac{1}{g}=\frac{1}{2-\sqrt{3}}$
⇒ $\frac{1}{g}=\frac{2+\sqrt{3}}{(2-\sqrt{3})(2+\sqrt{3})}$
⇒ $\frac{1}{g}=2+\sqrt{3}$
$\left(g^3-\frac{1}{g^3}\right)=(g-\frac{1}{g})(g^2+\frac{1}{g^2}+g×\frac{1}{g})$
⇒ $\left(g^3-\frac{1}{g^3}\right)=(2-\sqrt{3}-(2+\sqrt{3}))((4+3-4\sqrt{3})+(4+3+4\sqrt{3})+1)$
⇒ $\left(g^3-\frac{1}{g^3}\right)=-2\sqrt{3}(15)$
⇒ $\left(g^3-\frac{1}{g^3}\right)=-30\sqrt{3}$
Hence, the correct answer is $-30\sqrt{3}$.

Option 1: 40.8 km

Option 2: 36.4 km

Option 3: 46.6 km

Option 4: 43.2 km

Given:
Speed = 6 m/s
Time = 2 hours = 7200 seconds (since 1 hour = 3600 seconds)
Substituting these values into the formula,
Distance = 6 × 7200 = 43200 m = 43.2 km

Question : In the shown figure, BC is a chord and CD is a tangent through the point C. If $\angle AOC=112^{\circ}$, then find $\angle ACD$.

Option 1: 63°

Option 2: 59°

Option 3: 65°

Option 4: 56°

Team Careers360 25th Jan, 2024

Correct Answer: 56°


Solution : The angle subtended by an arc of a circle at its centre is twice the angle it subtends on any point of the circle's circumference.
So, $\angle$AOC = 2 $\angle$ABC
⇒ 112°= 2 $\angle$ABC
⇒ $\angle$ABC = 56°
Also, $\angle$ABC = $\angle$ACD
⇒ $\angle$ACD =
