5) The height of a rocket after it is launched
 For this case, what you should do is remember the kinematics expressions where we have:
 a
 v = a * t + vo
 y = a * t ^ 2 + vo * t + i
 Where,
 a: acceleration
 v: speed
 y: vertical position
 t: time
 vo: initial speed
 yo: initial position
 We observe that the expression for the given position is given by a quadratic expression.

Here are two offers for batteries.
trapecia [35]

OFFER A is cheaper.

Step-by-step explanation:

Given,

OFFER A

Pack of 5

£2.75

Pay for 3 packs get 1 free

And

OFFER A

Pack of 5

£2.75

Pay for 3 packs get 1 free

To find which offer is cheaper.

<u>For OFFER A</u>

For 4 Packets he needs to pay £2.75

He needs to buy 40 batteries.

He needs to buy 40÷(4×5) = 2 packets.

Total cost = £2.75 ×2 = £5.5

<u>For OFFER B</u>

For 4 Packets he needs to pay £2.52

He needs to buy 40 batteries.

He needs to buy 10 packets.

After discount he has to pay = £2.52 -(£2.52 ×\frac{1}{3}) = £1.68

Total cost = £1.68×10 = £16.8

Hence,

OFFER A is cheaper.
