The logarithmic model for the length when the strength is of 8 Pascals is given by:
- That is, the length is of 3 units.
<h3>What is the function?</h3>
The strength in Pascals for a building of length x is given by:
To find the length given the strength, we apply the inverse function, that is:
Hence, when the strength is of 8 Pascals, 
, and the length is given by:

Answer:
$0.96
Step-by-step explanation:
To find the unit price is to find the price of 1 meter.
9m = $8.64
1 m = 8.64 ÷ 9 = $0.96
-3 + 3n = -6 - 6n. Expand the brackets
3n + 6n = -6 + 3. Collect like terms
9n = -3
n = -3/9 = -1/3
The base of the triangle is 6 - 2 = 4 units
The height is 6 - 1 = 5 units
Area = 1/2 x 4 x 5 = 10 square units
