Question 1

Differentiate $(2 x + 5)^{2} (x - 4)$ with respect to x.

Options

A) $4 (2 x + 5) (x - 4)$

B) $4 (2 x + 5) (4 x - 3)$

C) $(2 x + 5) (2 x - 13)$

D) $(2 x + 5) (6 x - 11)$

The correct answer is D.

Explanation:

To differentiate $(2 x + 5)^{2} (x - 4),$ you first need to know that it is a product function.
Using the product rule you have $\frac{d y}{d x} = \frac{u d v}{d x} + \frac{v d u}{d x}$
Let $(2 x + 5)^{2}$ be $u$ and $(x - 4)$ be $v .$
To find $d u$ we use the chain rule which is $\frac{d u}{d x} = \frac{d u}{d w} \times \frac{d w}{d x}$
We say let $(2 x + 5)$ be $w$
We then have a new function $u = w^{2}$
$\frac{d u}{d w} = 2 w$
$\frac{d w}{d x} = 2$
So $\frac{d u}{d x} = 2 \times 2 w$ which equals $4 w$ and $w$ was $(2 x + 5)$
$\frac{d u}{d x} = 4 (2 x + 5)$
$\frac{d v}{d x} = 1$
Substituting everything into the product rule we have:
$\frac{d y}{d x} = (2 x + 5)^{2} (1) + 4 (2 x + 5) (x - 4)$
$\frac{d y}{d x} = (4 x^{2} + 20 x + 25) + (8 x^{2} - 12 x - 80)$
$\frac{d y}{d x} = 12 x^{2} + 8 x - 55$
$\frac{d y}{d x} = (2 x + 5) (6 x - 11)$

Question 2

Find the area bounded by the curves $y = 4 - x^{2}$ and $y = 2 x + 1$

Options

A) $20 \frac{1}{3}$ sq. units

B) $20 \frac{2}{3}$ sq. units

C) $10 \frac{2}{3}$ sq. units

D) $10 \frac{1}{3}$ sq. units

The correct answer is C.

Explanation:

$y = 4 - x^{2}$ and $y = 2 x + 1$
$\Rightarrow 4 - x^{2} = 2 x + 1$
$\Rightarrow x^{2} + 2 x - 3 = 0$
$(x + 3) (x - 1) = 0$
Thus, $x = - 3$ or $x = 1.$

Integrating $x^{2} + 2 x - 3$ from $(- 3$ to $1)$ concerning $x$ will give $\frac{32}{3} = 10 \frac{2}{3}$

Question 3

Find the rate of change of the volume, $V$ of a sphere concerning its radius, $r$ when $r = 1.$

Options

A) $12 π$

B) $4 π$

C) $24 π$

D) $8 π$

The correct answer is B.

Explanation:

The volume of a sphere, $V = \frac{4}{3} \times π r^{3}$
Rate of change of $V = \frac{d v}{d r}$
Thus if, $V = \frac{4}{3} \times π r^{3},$
$\Rightarrow \frac{d v}{d r} = 4 π^{2}$
At $r = 1,$ Rate $= 4 \times π \times 1 = 4 π$

Question 4

If $y = x s i n x,$ find $\frac{d y}{d x}$ when $x = \frac{π}{2} .$

Options

A) $\frac{- π}{2}$

B) $- 1$

C) $1$

D) $\frac{π}{2}$

The correct answer is C.

Explanation:

$y = x s i n x$
$\frac{d y}{d x} = 1 \times s i n x + x c o s x$
$= s i n x + x c o s x$
At $x = \frac{π}{2},$ $= s i n \frac{π}{2} + \frac{π}{2} c o s \frac{π}{2}$
$= 1 + \frac{π}{2} \times (0) = 1$

7 Tips to Prepare for WAEC Maths Exams

Don’t make reading your hobby: A lot of people put reading as a hobby in their CV, they might be right because they have finished schooling. But “You” are still schooling, so reading should be a top priority, not a hobby. Read far and wide to enhance your level of aptitude
Get Exams Preparation Materials: These involve textbooks, dictionaries, Babcock University Post UTME Past Questions and Answers, mock questions, and others. These materials will enhance your mastery of the scope of the exams you are expecting.
Attend Extramural Classes: Register and attend extramural classes at your location. This class will help you refresh your memory and boost your classroom understanding and discoveries of new knowledge.
Sleep when you feel like: When you are preparing for any exams, sleeping is very important because it helps in the consolidation of memory. Caution: Only sleep when you feel like it and don’t oversleep.
Make sure you are healthy: Sickness can cause excessive feelings of tiredness and fatigue and will not allow you to concentrate on reading. If you are feeling as if you are not well, report to your parent, a nurse, or a doctor. Make sure you are well.
Eat when you feel like it: During the exam preparation period, you are advised not to overeat, and to avoid sleep. You need to eat little and light food whenever you feel like eating. Eat more fruits, drink milk and glucose. This will help you enhance retention.
Reduce your time on social media: Some people live their entire lives on Facebook, Twitter, WhatsApp, Messenger chat. This is so bad and catastrophic if you are preparing for exams. Try and reduce your time spent on social media during this time. Maybe after the exams, you can go back and sleep in it.
