Answer:
see below
Step-by-step explanation:
the circumference of a circle is
in our problem
r=11
rounded to the nearest tenth
the area of a circle is
so the area is
rounded to nearest tenth
Not only can be more easily understood by some people, but it can also illustrate the exact course a line will take rather than just giving some of the coordinates. Furthermore, a graph is less accurate due to the fact that lines are infinite and can express all the numbers they cross rather than just giving a limited amount of numbers.
Answer:
y = x-20
Step-by-step explanation:
<h2><u>finding the equation of the line</u></h2>
get 2 points A and B , they are an on the line
make sure its in the form (x,y)
A = (0 , -20)
B = ( 70 , 50)
<h2><u>now get the gradient</u></h2>
gradient =
=
= 70/70
gradient = 1
<h2><u>now make the equation</u></h2>
m is the gradient
y- y1 = m (x-x1)
y- -20 = 1 (x - 0)
y + 20 = x
put in the form y = mx +c
therefore
<u>y = x - 20</u>
