Question

a ball is dropped from the top of a building. the expression 4.9x^2 gives the distance in meters The ball house phone after X seconds. Right and simple fly in expression gives the distance in meters the wall has fallen after X squared seconds after X cubed seconds

Answer 1

The given general formula is

Distance = 4.9x², where x is in seconds

The first case is when the time is after x² seconds. So, if x=x²,
Distance = (4.9)(x²)²
From the laws of exponents, we multiply 2*2.
Distance = 4.9x⁴ meters

The second case is when the time is after x³ seconds. So, if x=x³,
Distance = 4.9(x³)²
Distance = 4.9x⁶ meters
