**Question 1**

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

### Options

A) 4(2x+5)(x−4)

B) 4(2x+5)(4x−3)

C) (2x+5)(2x−13)

D) (2x+5)(6x−11)

**The correct answer is D.**

### Explanation:

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

Using the product rule you have dydx=udvdx+vdudx

Let (2x+5)2 be u and (x−4) be v.

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

We say let (2x+5) be w

We then have a new function u=w2

dudw=2w

dwdx=2

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

dudx=4(2x+5)

dvdx=1

Substituting everything into the product rule we have:

dydx=(2x+5)2(1)+4(2x+5)(x−4)

dydx=(4×2+20x+25)+(8×2−12x−80)

dydx=12×2+8x−55

dydx=(2x+5)(6x−11)

**Question 2**

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

### Options

A) 2013 sq. units

B) 2023 sq. units

C) 1023 sq. units

D) 1013 sq. units

**The correct answer is C.**

### Explanation:

y=4−x2 and y=2x+1

⇒4−x2=2x+1

⇒x2+2x−3=0

(x+3)(x−1)=0

Thus, x=−3 or x=1.

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

**Question 3**

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

### Options

A) 12π

B) 4π

C) 24π

D) 8π

**The correct answer is B.**

### Explanation:

Volume of sphere, V=43×πr3

Rate of change of V=dvdr

Thus if, V=43×πr3,

⇒dvdr=4π2

At r=1, Rate =4×π×1=4π

**Question 4**

If y=xsinx, find dydx when x=π2.

### Options

A) −π2

B) −1

C) 1

D) π2

**The correct answer is C.**

### Explanation:

y=xsinx

dydx=1×sinx+xcosx

=sinx+xcosx

At x=π2, =sinπ2+π2cosπ2

=1+π2×(0)=1

**Question 5**

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

### Options

A) square of sides p

B) square of sides 2p

C) square of sides p2

D) square of sides p4

The correct answer is D.

### Explanation:

Let the rectangle be a square of sides p4.

So that perimeter of square =4p
