Step-by-step explanation:
the starting point is 65,000
since the value of the land has been decreasing by 1% annually, it would be (0.99)^t
t = number of years = 20
equation: 65000(0.99)^20 = 531563.95

Correct a₂ > a₁
Explanation:
Given:
Tony mass = m₁ = 50 kg
Sam mass = m₂ = 45 kg
According to Newton's second law, the formula for calculating force is:
F = m · a
In this case we have the same force for both
F = m₁ a₁ = m₂ a₂ => a₁ / a₂ = m₂ / m₁ = 45 / 50 = 9 / 10 = 0.9
a₁ = 0.9 a₂ => a₁ = 90% of a₂ => a₂ > a₁
a₂ > a₁
