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) 

C) 24π

D) 

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
