Answer: 0.970 ??
Step-by-step explanation:
We have to determine if the sets of quadratics are equivalent:
A ) x² - 10 x - 14 = 0 and ( 2 x - 10 )² = 156
( 2 x - 10 )² - 156 = 0
4 x² - 40 x + 100 - 156 = 0
4 x² - 40 x - 56 = 0 / : 4
x² - 10 x - 14 = 0 T ( True )
B ) ( x - 10 )² = 68 and x² - 20 x = - 32
( x - 10 )² = 68
x² - 20 x + 100 = 68
x² - 20 x = 68 - 100
x² - 20 x = - 32 T ( True )
C ) x² - 6 x = 247 and ( x - 3 )² = 256
( x - 3 )² = 256
x² - 6 x + 9 = 256
x² - 6 x = 247 T ( True )
D ) ( x + 5 )² = 65 and x² = 90 - 10 x
( x + 5 )² = 65
x² + 10 x + 25 = 65
x² = 65 - 25 - 10 x
x² = 40 - 10 x F ( False )

Answer:
The line segment HK is the diameter.
Step-by-step explanation:
A straight line segment that passes through the center of the circle, and whose endpoints lie on its circumference, represents the diameter of the circle.
From the choices given, we see that two straight segments HK and GJ pass through the center of the circle, and have endpoints at the circumference. and since choice GJ is not given in the options, we choose HK as the right diameter of the circle.
<em>P.S: looking at other choices, we see that the segment GK represents the chord, JL represents the radius, and IL also represents the radius.</em>
