Answer:

Area = 2m^8 - 6m^4 + 4.5

Step-by-step explanation:

Given

Base = 2m^4 - 3

Height = 2m^4 - 3

Required

The area

This is calculated as:

Area = 0.5 * Base * Height

Area = 0.5 * (2m^4 - 3) * (2m^4 - 3)

Open brackst

Area = 0.5 * (4m^8 - 6m^4 - 6m^4 + 9)

Area = 0.5 * (4m^8 - 12m^4 + 9)

Open bracket

Area = 2m^8 - 6m^4 + 4.5

Answer:

x ≈ 3.1 ft

Step-by-step explanation:

The segment from the centre to the chord is a perpendicular bisector, thus

The triangle is right with base = \frac{1}{2} x

Applying Pythagoras' identity to the right triangle, then

(\frac{1}{2} x )² + 1.4² = 2.1²

\frac{1}{4} x² + 1.96 = 4.41 ( subtract 1.96 from both sides )

\frac{1}{4} x² = 2.45 ( multiply both sides by 4 )

x² = 9.8 ( take the square root of both sides )

x = \sqrt{9.8} ≈ 3.1 ft ( to the nearest tenth )
