#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.

HURRY Which is an equation in point-slope form for the line that passes through the points (−1,4) and (3,−4) ?
mash [69]

Answer:

y-4=-2(x+1)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(-4-4)/(3-(-1))

m=-8/(3+1)

m=-8/4

m=-2

y-4=-2(x-(-1))

y-4=-2(x+1)

x= -0.25 and 1.25

x = -0.5 and  1.5

x = 0 and 1

x = -0.375 and 1.625

Step-by-step explanation:

Given equation of the curve is

y = 4x^2 -4x-1

(i)

First equation 4x^2 -4x-1 =0

Here y = 0

In  x-axis the value of y = 0

The graph cuts the x-axis at(-0.25,0) and (1.25,0)

So, x= -0.25 and 1.25

(ii)

4x^2 -4x-1 =2

here y = 2

The line y= 2 cuts the curve at (-0.5,2) and (1.5,2)

So, x = -0.5 and  1.5

Given equation of the curve is

y= 3x^2-3x -1

(i)

3x^2-3x +2 =2

\Leftrightarrow  3x^2-3x -1 = -1

Here y = -1

The line y = -1  cuts the curve at (0,-1) and (1,-1)

So x = 0 and 1

(ii)

3x^2-3x -1 =x+1

Here y = x+1

The line y -x =1 cuts the curve at (-0.375,0.5) and (1.625,2).

So x = -0.375 and 1.625
