If c and k are the roots of 6 - x - x2 = 0, find c + k
2
1
-1
-3
Correct answer is C
6 - x - x2 = 0
a = -1; b = -1; c = 6
Sum of roots = c + k = -−ba
= −(−1)−1
= -1
If a positive integer, list the values of x which satisfy the equation 3x - 4 < 6 and x - 1 > 0
{1, 2, 3}
{2, 3}
{2, 3, 4}
{2, 3, 4, 5}
Correct answer is B
3x - 4 < 6 = 3x < 6 = 4
3x < 10
x < 103
x < 3.33 and x - 1 = 0
n > 1 = 1< x; since x is an integer, and 1 < x3.33
x = {2, 3}
1
15
-15
-1
Correct answer is A
2x+16−3x−14 = 0
4(2n+1)−6(3x−1)24 = 0
-10x + 10 = 0
-10x = -10
x = −10−10
x = 1
πcm
2πcm
3πcm
6πcm
Correct answer is A
Length of arc = θ360×2πr
= 60360×2π×3cm
= πcm
