If line ab is a diameter of circle o that bisects chord line cd at point e, which of the following statements is true?

A: The chord is perpendicular to the diameter

Proof:

CE=DE (definition of bisector)

Center O, so OC and OD are radii.

OC=OD.

OE=OE.

OCE=ODE  (SSS)

angle OEC = angle OED  (corresponding parts)

angle OEC  and angle OED are supplementary

So angle OEC and angle OED are both right angles.

CD is perpendicular to OE

CD is perpendicular to AB

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
