Answer:
Step-by-step explanation:
Given: f(x) = 4(3x - 5)
Is required to find f⁻¹(x)
f(x) = y = 4(3x - 5)
∴ y = 4 * 3x - 4 * 5
∴ y = 12x - 20 ⇒ add 20 to both sides
∴ y + 20 = 12x ⇒ divide both sides by 12
∴
Replace the places of x and y.
∴
∴

<u>Given:</u>
- Diameter of rug = 6 feet
To find the area of the rug, we need to use the formula "πr² or π(D/2)²"
<u>Where:</u>
- r = radius
- d = diameter
Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.
