Help pls i need this luv you guys ,<333

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 = x

Applying Pythagoras' identity to the right triangle, then

( x )² + 1.4² = 2.1²

x² + 1.96 = 4.41 ( subtract 1.96 from both sides )

x² = 2.45 ( multiply both sides by 4 )

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

x = ≈ 3.1 ft ( to the nearest tenth )

the answer is  

a.

28 ft2

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
