2cm
4cm
5cm
8cm
10cm
Correct answer is B
Volume of cuboid = length x breadth x height 12.5 x 20 x h = 1000 250h = 1000 h = 4 cm
3cm
6cm
\(4\sqrt{2}\) cm
\(3\sqrt{3}\) cm
\(6\sqrt{3}\) cm
Correct answer is E
\(\frac{r}{6} = \sin 60 \)
\(r = 6 \sin 60\)
= \(6 \times \frac{\sqrt{3}}{2}\)
= \(3\sqrt{3}\)
Chord = 2r = \( 2 \times 3\sqrt{3}\)
= \(6\sqrt{3}\)
Solve the equation log8x - 4log8x = 2
1/4
1/2
1
2
4
Correct answer is A
log8x - 4log8x = 2; log8x - log8x4 = 2
log8x/x4 = 2
x/x4 = 82 = 1/x3 = 64
x3 = (1/4)3; x = 1/4
Factorise: 6x\(^2\) + 7xy - 5y\(^2\)
(6x + 5y)(x - y)
(2x + 5y)(3x - y)
(3x + y)(2x - 5y)
(3x + 5y)(2x - y)
(2x + y)(3x - 5y)
Correct answer is D
\(6x^2 + 7xy - 5y^2\)
= \(6x^2 + 10xy - 3xy - 5y^2\)
= \(2x(3x + 5y) - y(3x + 5y)\)
= \((2x - y)(3x + 5y)\)
Which of the following is a root of the equation x\(^2\) +6x = 0?
0
1
2
3
It does not have any root.
Correct answer is A
\(x^2 + 6x = 0\)
\(x(x + 6) = 0\)
\(x = 0\) or \(x = -6\)
