<em>$29178.25</em>
- Step-by-step explanation:
<em>x = p(1 - r)ⁿ</em>
<em>p = original price</em>
<em>r = 8.3% = 0.083</em>
<em>n = 5 years</em>
<em>x = $45000(1 - 0.083)⁵</em>
<em>= $45000ₓ0.917⁵</em>
<em>= $45000ₓ0.64840548256</em>
<em>= </em><em>$29178.25</em>
Answer:

Step-by-step explanation:
Given
When mass = 4kg; Acceleration = 15m/s²
Required
Determine the acceleration when mass = 10kg, provided force is constant;
Represent mass with m and acceleration with a
The question says there's an inverse variation between acceleration and mass; This is represented as thus;

Convert variation to equality
; Where F is the constant of variation (Force)
Make F the subject of formula;

When mass = 4kg; Acceleration = 15m/s²


When mass = 10kg; Substitute 60 for Force



Divide both sides by 10


<em>Hence, the acceleration is </em>

Actual length = 3.5 × 120
actual length = 420 cm
actual length = 4.2 m
actual width = 2.5 × 120
actual width = 300 cm
actual width = 3 m
actual area = l × w
actual area = 4.2 × 3
actual area = 12.6 m²
the answer is b
