**Question 1**

Differentiate (2x+5)2(x−4)(2x+5)2(x−4) with respect to x.

### Options

A) 4(2x+5)(x−4)4(2x+5)(x−4)

B) 4(2x+5)(4x−3)4(2x+5)(4x−3)

C) (2x+5)(2x−13)(2x+5)(2x−13)

D) (2x+5)(6x−11)(2x+5)(6x−11)

**The correct answer is D.**

### Explanation:

To differentiate (2x+5)2(x−4),(2x+5)2(x−4), you first need to know that it is a product function.

Using the product rule you have dydx=udvdx+vdudxdydx=udvdx+vdudx

Let (2x+5)2(2x+5)2 be uu and (x−4)(x−4) be v.v.

To find dudu we use chain rule which is dudx=dudw×dwdxdudx=dudw×dwdx

We say let (2x+5)(2x+5) be ww

We then have a new function u=w2u=w2

dudw=2wdudw=2w

dwdx=2dwdx=2

So dudx=2×2wdudx=2×2w which equals 4w4w and ww was (2x+5)(2x+5)

dudx=4(2x+5)dudx=4(2x+5)

dvdx=1dvdx=1

Substituting everything into the product rule we have:

dydx=(2x+5)2(1)+4(2x+5)(x−4)dydx=(2x+5)2(1)+4(2x+5)(x−4)

dydx=(4×2+20x+25)+(8×2−12x−80)dydx=(4×2+20x+25)+(8×2−12x−80)

dydx=12×2+8x−55dydx=12×2+8x−55

dydx=(2x+5)(6x−11)dydx=(2x+5)(6x−11)

**Question 2**

Find the area bounded by the curves y=4−x2y=4−x2 and y=2x+1y=2x+1

### Options

A) 20132013 sq. units

B) 20232023 sq. units

C) 10231023 sq. units

D) 10131013 sq. units

**The correct answer is C.**

### Explanation:

y=4−x2y=4−x2 and y=2x+1y=2x+1

⇒4−x2=2x+1⇒4−x2=2x+1

⇒x2+2x−3=0⇒x2+2x−3=0

(x+3)(x−1)=0(x+3)(x−1)=0

Thus, x=−3x=−3 or x=1.x=1.

Integrating x2+2x−3×2+2x−3 from (−3(−3 to 1)1) with respect to xx will give 323=1023323=1023

**Question 3**

Find the rate of change of the volume, VV of a sphere with respect to its radius, rr when r=1.r=1.

### Options

A) 12π12π

B) 4π4π

C) 24π24π

D) 8π8π

**The correct answer is B.**

### Explanation:

Volume of sphere, V=43×πr3V=43×πr3

Rate of change of V=dvdrV=dvdr

Thus if, V=43×πr3,V=43×πr3,

⇒dvdr=4π2⇒dvdr=4π2

At r=1,r=1, Rate =4×π×1=4π=4×π×1=4π

**Question 4**

If y=xsinx,y=xsinx, find dydxdydx when x=π2.x=π2.

### Options

A) −π2−π2

B) −1−1

C) 11

D) π2π2

**The correct answer is C.**

### Explanation:

y=xsinxy=xsinx

dydx=1×sinx+xcosxdydx=1×sinx+xcosx

=sinx+xcosx=sinx+xcosx

At x=π2,x=π2, =sinπ2+π2cosπ2=sinπ2+π2cosπ2

=1+π2×(0)=1=1+π2×(0)=1

**Question 5**

Find the dimensions of a rectangle of greatest area which has a fixed perimeter p.p.

### Options

A) square of sides pp

B) square of sides 2p2p

C) square of sides p2p2

D) square of sides p4p4

The correct answer is D.

### Explanation:

Let the rectangle be a square of sides p4.p4.

So that perimeter of square =4p=4p

4×p4=p.
