OK.  Take it slow and easy, one step at a time.

-- Draw a line from the center of the circle to the left end of the
horizontal chord.
(That point doesn't have an identification letter, but it's the other
end of the '10' from point 'A'.)

-- Since that line is also a radius of the circle, its length is 14.5 .

-- When you drew the line, you made a right triangle inside the circle. 
The line you drew is the hypotenuse of the right triangle.

-- You know the length of the hypotenuse (14.5), and you know
the length of one leg (10).  So you can calculate the length of the
other leg ... from the center to point 'A'.  That leg is √(14.5² - 10²)

-- Now you know the distance from the center of the circle to point 'A'.
The length of AB is (the radius) minus (the leg that you just found).

Seem reasonable ?

I got 4 for AB.  But I was working fast and sloppy.  You need to check it.

What is the sum of the rational expressions below?<br> x/5+2/3x

Re-write the quadratic function below in Standard Form y= -9(x+3)2+2
disa [49]

Answer:

18x+y=-52

Step-by-step explanation:

we all know and love(being 100% sarcastic here)the standard form  as

ax+by=c

y=-9(x+3)*2+2----This is weird and not so nice

so lets make it nice by distributing the 9::::

y=(-9x-27)2+2

and now the 2:

y=-18x-54+2

y=-18x-52

oops this is NOT in S.F we got to switch the -52 and y

52=-18x-y

-18 cant be neg. so we have to divide by -1 on both sides

-52=18x+y

18x+y=-52

HOPE THIS HELPS
