Answer:
The correct answer is $3300 for simple interest and $3312.24 for compound interest.
Step-by-step explanation:
Income as working as a lifeguard = $3000
We deposit the money in a bank which offers 2% interest annually for a period of 5 years.
Case 1 : Calculating simple interest for the given situation.
Amount after 5 years = 3000 + 3000 × 2 × 5 ×
= $ ( 3000 + 300) = $3300.
Case 2 : Calculating compound interest for the given situation.
Amount after 5 years = 3000 ×
= $ 3312.24.
Thus the amount after 5 years amount simply is $3000 and compoundly is $3312.24

Answer:
Given: In triangle ABC , AD is drawn perpendicular to BC.
Since AD is drawn perpendicular to BC, it creates two right triangles: ADB and ADC.
Prove that: 
Pythagoras triangle for right angle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.
In a right angle triangle ADB;
[By Pythagoras theorem]
or
.......[1]
Now, in right angle triangle ADC;
[By Pythagoras theorem]
or we can write this as;
......[2]
Substituting the equation [1] in [2] we get;
hence proved!
