A binary operation * is defined on the set of real numbers, R, by
P * q = q2−p22pq. Find 3 * 2
1312
512
-512
−12
Correct answer is C
P * q = q2−p22pq.
3 * 2 (where p = 3, q = 2)
i.e 3 *2 = 32−222∗3∗2
= 4−912
= −512
For what value of k is 4x2 - 12x + k, a perfect square?
-9
−94
94
9
Correct answer is D
4x2 - 12x + k;
a = 4, b = -12, c = k.
For perfect square b2 = 4ac
(-12)2 = 4 * 4 * k;
144 = 16k
k = 144\16
k = 9
If f(x) = 4x3 + px2 + 7x - 23 is divided by (2x -5), the remainder is 7. find the value of p
-7.0
-8.0
-9.6
9
Correct answer is B
f(x) = 4x3 + px2 + 7x - 23
If f(x) is divided by (2x -5), the remainder is f(52)
f52 = 4523 + p522 + 752 - 23
Hence;
= 1258 + 254 p + 352 - 23
28 = 250 + 250p + 70 - 92
25p = -200; p = -8.0
If α and β are the roots of 3x2 - 7x + 6 = 0, find \frac{1}{α} + \frac{1}{β}
\frac{7}{6}
\frac{7}{3}
\frac{14}{5}
\frac{14}{3}
Correct answer is A
3x^2 - 7x + 6 = 0
α + β = \frac{7}{3};
αβ = 2;
\frac{1}{α} + \frac{1}{β} = \frac{α +β}{αβ}
\frac{7}{3} ÷ 2
= \frac{7}{6}
In how many ways can 8 persons be seated on a bench if only three seats are available?
100
125
336
427
Correct answer is C
^3{P}_3 = \frac{8!}{8-3}!
= \frac{(8 * 7 * 6 * 5)!}{5!}
= 336
