There wasn't much to go off of but based of the information you've gave me the answer would be 7.68=6.28

Actually the circumference of a circle is :

C =2Pi*r

Where r = radius, the radius term r, was missing in your expression.

C = 2Pi*r

7.68 = 2*3.14*r

2*3.14*r = 7.68

6.28r = 7.68

r = 7.68 / 6.28

<span>r ≈ 1.223

So in solving for the missing variable, </span><span>r ≈ 1.223

Hope this explains it.</span>

<h3>The y intercept is -1</h3>

We can say that the y intercept is at the location (0,-1)

This is where the graph crosses the vertical y axis. This is 1 unit below the origin.

This is assuming each tickmark on the grid represents 1 unit.

Given that the line is x/3 + y/2 =1<br> i ) make y the subject<br> ii ) gradient of line
miss Akunina [59]

Answer:

see explanation

Step-by-step explanation:

(i)

\frac{x}{3} + \frac{y}{2} = 1 ( multiply through by 6 to clear the fractions )

2x + 3y = 6 ( subtract 2x from both sides )

3y = - 2x + 6 ( divide through by 3 )

y = - \frac{2}{3} x + 2

(ii)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope ( gradient ) and c the y- intercept )

y = - \frac{2}{3} x + 2 ← is in slope- intercept form ( that is part (i)

with gradient m = - \frac{2}{3}

Consider lines An and CD
vichka [17]

Answer:

slope of AB = 2

slope CD = 2

Step-by-step explanation:

the equation of a line is y = ax+ b  where a is the slope, b is the y-intercept

let us take  yB - yA

→ yB - yA = axB <u>+ b</u> - axA <u>- b</u>

→ yB - yA = a(xB - xA)

→ a = (yB - yA) / (xB = xA)   =  (6 - 2) / (-5 - (-7)) = 2

same goes for line CD
