I think you're answer is five hundred seventy six
a
I searched and found this figure online.
I'm guessing there's additional information that OM perpendicular to CD and EF perpendicular to ON.
The diameters meeting chords at right angles also bisect the chords, so
CM = (1/2) CD = 28
The radius OC makes the hypotenuse of a right triangle with legs OM and CM
r² = OM² + CM² = 20² + 28² = 1184
r = 4√74
a Answer: 4√74
b
FN is the leg of a right triangle with other leg ON=16 and hypotenuse OF=r because it's a radius.
FN² = r² - ON² = 1184 - 16² = 1184 - 256 = 928
FN = √928
b Answer: √928
c
EF is twice FN by the perpendicular diameter bisecting a chord theorem.
EF = 2√928
Tenths?
c Answer: 60.9
Answer:plot these points and draw a straight line through them

To get the reciprocal of a number you divide 1 by that number. therefore the answer to this question is. 14705882 or 34/5
-5x+3y=19
<span>-5x+7y=11
Here, we use substitution to solve for both variables.
Solve for y first
-5x + 3y = 19
+5x +5x
3y = 19 + 5x
y = 19/5 + 5/3x
Now plug that into the other equation. </span>-5x+7(19/5 + 5/3x) =11
-5x + 26.6 + 35/3x = 11
-5x + 35/3x = 20/3x
20/3x + 26.6 = 11
-26.6 -26.6
11 - 26.6 = -15.6
20/3x = -15.6
x = -119.6
Ahhh, now time to solve for y
-5x+3y=19
-5(-119.6) + 3y = 19
598 + 3y = 19
-598 -598
19 - 598 = -579
3y = -579
y = - 193
WE ARE DONE!!!
Answer: y = -193 and x = -119.6
