The wire represents the circumference of a circle.
Circumference= πd
plug in the numbers you know
18.84= (3.14)d
divide both sides by 3.14
6= d
ANSWER: d=6 centimeters
Hope this helps! :)
The value of x in the segment is 3
<h3>How to determine the value of x?</h3>
Using the secant and segment theorem, we have:
x * (x + 21) = (x + 1) * (x + 1 + 14)
Evaluate the sum
x * (x + 21) = (x + 1) * (x + 15)
Expand
x^2 + 21x = x^2 + 15x + x + 15
Subtract x^2 from both sides
21x = 15x + x + 15
Evaluate the like terms
5x = 15
Divide both sides by 5
x = 3
Hence, the value of x is 3

Step-by-step explanation:
f(x)=x^4+2x^2-1
Let x = -2
f(-2) = (-2)^4 +2(-2)^2 -1
=16 +2*4-1
=16+8-1
