Answer:
Step-by-step explanation:
The equation of the line parallel to
y = x
has a slope of m = 1
This means that the family of lines with the same slope are of the form
y = x - (a)
where -a represents the y intercept, and (a) the x- intercept
With a = 4, the equation intercepts the x axis at x = 4
Please see attached graph
THE STEPS AND ANSWER IS IN THE PICTURE
#1). The length of the whole circumference is (π · D) = 12π .
120° is 1/3 of 360°, so arc-AB is 1/3 of the whole circumference.
#2). 60° is 1/6 of 360°.
So arc-CD is 1/6 of the whole circumference (which is given).
#3). The circumference of the circle is (π·D) = 20π .
70° is (70°/360°) of the whole circle, so arc-XY
is (70/360) of the whole circumference.
#4). Sorry, I don't remember anything right now about
angles between chords.
I hope what I've given you so far is worth 5 points.
Answer:
125
Step-by-step explanation:
anything that is above .5 will round up and below .4 will round down.
Answer:
radius = 8
Step-by-step explanation:
the equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 64 ← is in this form
with r = 
= 8
