Answer:

x = 3 is the line of symmetry.

Step-by-step explanation:

In this question we have to find the equation of line of symmetry which is the average of x-intercepts.

Given quadratic function is f(x) = 4x² - 24x + 20

Now we know line of symmetry is denoted by x = -\frac{b}{2a}

From the quadratic function

a = 4

and b = -24

therefore, equation of symmetry will be x = -[\frac{-24}{(2)(4)}]

x = 3

Therefore, x = 3 is the line of symmetry for the given function.

Circle O has a circumference of approximately 250π ft. Circle O with diameter d is shown. What is the approximate length of the
Vinil7 [7]

Answer:

250 ft

Step-by-step explanation:

circumference of circle 'C' is defined as

C = 2πr

250π = 2πr

r = 250π/2π

r= 125

d = 2r = 2×125 = 250 .

diameter of the given circle is 250 ft
