Waec Mathematics Questions And Answers Sample Past Questions

Objectives

1. Which of those numbers will not be lower than -2?

  1. -1,

  2. -3,

  3. -4,

  4. -5.

  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

  1. True

  2. Both

  3. False

  4. 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

  1. 22b + 28a

  2. -22b + 28a

  3. 22b – 28a

  4. -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)?

  1. 2×2 + 5x – 42

  2. 2×2 – 5x – 42

  3. 2×2 – 5x + 42

  4. 2×2 + 5x + 42

  5. -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. Factorise the next: 5×2 – 15x – 20?

  1. 5(x+4)(x+1).

  2. -2(x-4)(x+5)

  3. -5(x+4)(x-1)

  4. 5(x-4)(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(x-4)(x+1).

The Correct Answer is D): 5(x-4)(x+1)

6. Find the sum of the primary for time period provided that the 2nd and fifth phrases of a G.P are 6 and 48 respectively.

A. -45
B. -17
C. 17
D. 32
E. 45
Answer: E (45)

7. If sinθθ = Okay discover tanθθ, 0° ≤≤ θθ ≤≤ 90°.

  • A. 1-Okay

  • B. kk−1kk−1

  • C. k1−k2√k1−k2

  • D. k1−kk1−ok

  • E. kk2−1√

Answer: C ( k1−k2√k1−k2 ) See Solution Below:

sinθ=k1sin⁡θ=k1

⟹12=k2+adj2⟹12=k2+adj2

adj=1−k2−−−−−√adj=1−k2

∴tanθ=k1−k2√

8. Find the eighth time period of the A.P -3, -1, 1 ……

A. 14
B. 11
C. -9
D. -11
E. -18
Answer: B ( 11 ) Crosscheck the reply under:

9. If cos 60° = 1/2, which of the next angle has a cosine of -1/2?

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

10. Solve the simultaneous linear equations 2x-y=8 x-y=4

A.x= 4, y=0
B. x=4, y=2
C. x= 2, y=8
D. x= 2, y=4
E. x=2, y=-4

Answer: D-  x=2, y=4

Subjective

  1. 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  

  1. Using scales of two cm to 1 unit on the x-axis 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.

  2. Use the graph to estimate the:

  3. 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

(Image Source: nkedugists.com.ng)

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 universal-set
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}
