Answer:
4
Step-by-step explanation:
the formula for radius is

so. 500 divided by pi times 10. then square root your final answer. cool. let's get started.
3.14*10 is 31.4, you can do that without thinking.
500/31.4=15.92
15.92= 3.99, or just 4
the radius is four.
Answer:
The slope of the line is
and the equation of the line is
.
Step-by-step explanation:
From table we understand that slope of the line is constant, that is, for each change of
there is one and only change in
, fulfilling the main characteristic of a line and we can determine the slope for every point of the line by means of the following expression:
(1)
Where:
- Initial and final x-coordinates of the line.
- Initial and final y-coordinates of the line.
If we know that
and
, then the slope of the line is:


From graph we conclude that x-intercept of the line is
. Hence, the equation of the line is
and we proceed to plot the expression with the help of a graphing tool.
Step-by-step explanation:
=n2-11n+18
=n2-(9+2)n+18
=n2-9n-2n+18
=n(n-9)-2(n-9)
=(n-2)(n-9)
