8 0

Answer:

x=-1/8 or 3/8

Step-by-step explanation:

64x^2+16x-3=0

By Mid term breaking

64x^2-24x+8x-3=0

8x(8x-3)+1(8x-3)=0

(8x+1)(8x-3)=0

Either

8x+1=0 OR 8x-3=0

8x=-1 OR 8x=3

x=-1/8 OR x=3/8

pshichka [43]

Answer:

Option C. $8.125\ in$

Step-by-step explanation:

we know that

In this problem

The chord FE is a diameter of the circle

Applying the intersecting chords theorem

Let

O------> the intersecting point of both chords

$FO*OE=BO*OC$

substitutes the values

$2*OE=3.5*3.5$

solve for OE

$OE=3.5*3.5/2=6.125\ in$

The diameter is equal to

$D=FO+OE$

$D=2+6.125=8.125\ in$
