1,

3,

4,

5.

6
Solving: 2 is bigger than 2, 3, 4, 5, 6 and so forth. But 1 is bigger than 2.
The Correct Answer is A): Because it’s better than 2.
2. 6 is bigger than 2 however lower than 7? True or false

True

Both

False

None of the above
Solving: 6 is bigger than any quantity from 7 to the detrimental infinity however lower than any quantity from 5 to the constructive infinity.
The Correct Answer is C): Because 6 will not be better than 2 and it’s not lower than 7.
3. Add 26b + 12a + 16a – 4b

22b + 28a

22b + 28a

22b – 28a

22b – 28a
Solving: Firstly, it’s a must to Collect like phrases. Therefore, we’ve got;
26b – 4b + 12a + 16a.
Next, we’ve got 26b – 4b = 22b
And 12a + 16a = 28a
Therefore, we’ve got 22b + 28a
The Correct Answer is A): 22b + 28a
4. Multiply this equation: (x – 6)(2x + 7)?

2×2 + 5x – 42

2×2 – 5x – 42

2×2 – 5x + 42

2×2 + 5x + 42

2×2 + 5x – 42
Solving: Here, we begin by eradicating the bracket
Thus; 2×2 + 7x – 12x – 42
Hence, 2×2 – 5x – 42
The Correct Answer is B): 2×2 – 5x – 42

5(x+4)(x1)

5(x4)(x+1)
Solving: Firs discover the L.C.M of 5, 15 and 20 = 5(x2 – 3x – 4).
= 5(x2 – 4x + x – 4).
= 5{x(x – 4) +1(x – 4)}.
= 5(x4)(x+1).
The Correct Answer is D): 5(x4)(x+1)

E. kk2−1√
Answer: C ( k1−k2√k1−k2 ) See Solution Below:
sinθ=k1sinθ=k1
⟹12=k2+adj2⟹12=k2+adj2
adj=1−k2−−−−−√adj=1−k2
∴tanθ=k1−k2√

A. 30o
B. 120o
C. 150o
D. 210o
E. 300o
Answer: B ( 120o ) See the Solution Below:
cos 60° = 1/2, cos(180° – 60°) = 1/2
cos120° = 1/2

Answer: D x=2, y=4
Subjective

Copy and full the desk of values for the equation y = 2×2 – 7x – 9 for 3 ≤ x ≤ 6.
X  3  – 2  1  0  1  2  3  4  5  6 
Y  13  9  14  12  6 

Using scales of two cm to 1 unit on the xaxis and a couple of cm to 4 models on the y – axis, draw the graph of y = 2×2 – 7x – 9 for 3 ≤ x ≤ 6.

Use the graph to estimate the:

roots of the equation 2×2 – 7x = 26;
(ii) coordinates of the minimal level of y;
(iii) vary of values for which 2×2 – 7x < 9.
Solution
The Chief Examiner reported that almost all of the Candidates’ who tried this query obtained proper the whole desk of values for which y = 2×2 – 7x – 9. However, many did not plot the factors on the graph appropriately on the graph thereby shedding marks. Also, they might not learn up values from the graph to reply subsequent questions.
In half (a), the Candidates have been anticipated to finish the desk as follows:
X  3  – 2  1  0  1  2  3  4  5  6 
Y  30  13  0  9  14  15  12  5  6  21

In half (b), Candidates would then use this desk and the size supplied to attract the graph of the relation y = 2×2 – 7x – 9 and use this graph to reply the questions that adopted.
In half (c), from the graph, the roots of the equation 2×2 – 7x = 26 have been obtained by drawing a line by y = 17 to fulfill the curve y = 2×2 – 7x – 9. The required roots are – 2.2 ± 0.1 and 5.8 ± 0.1. The coordinates of the minimal level of y is 1.8 ± 0.1, 15 ± 0.4.
Question 2
Rationalize the expression 1/(√8 + √2 )
Solution
1/(√8 + √2 ) = 1/(√8 + √2 ) x (√8 – √2 )/(√8 – √2 )
= (√8 – √2 )/(√64√16 + √16 √4 ) = (√8 – √2 )/(√64 – √4 )
= (√8 – √2 )/(8 – 2 ) = (√8 – √2 )/(6 ) = (√(4×2) √2 )/6
= (2√2√2 )/(6 ) = ( √2 )/(6 )
Question 3
If y varies inversely because the sq. of T and y = 8 when T = 2 discover
T when y = 32
The relationship of the variable
Solution
y∝1/T^2
y=ok/T^2 ,8=ok/2^2 ,8=ok/4 ,ok=8×4=32 ,y=32/T^2
When y = 32
y=32/T^2
32=32/T^2
(32T^2)/32=32/32
T^2=1
T=√1
T=1
Question 4
1. A = {2, 4, 6, 8}, B = {2, 3, 7, 9} and C = {x: 3 < x < 9} are subsets of the universalset
U = {2, 3, 4, 5, 6, 7, 8, 9}. Find
(a) A n(B’nC’);
(b) (AuB) n(BuC).
Solution
Given A={2,4,6,8,…}
B={3,6,9,12,…}
C={1,2,3,6}
U= {1,2,3,4,5,6,7,8,9,10}
A’ = {1,3,5,7,9}
B’ = {1,2,4,5,7,8,10}
C’ = {4,5,7,8,9,10}
A’nB’nC’ = {5, 7}
