Answer:
The gradient of the line joining the points
and
is
.
Step-by-step explanation:
The gradient of the line joining two distinct point on a plane is represented by the slope of a secant line (
), that is:
(1)
If we know that
and
, then the gradient of the line is:


The gradient of the line joining the points
and
is
.
Answer:
2
Step-by-step explanation:
Answer:
0.1*√20000 = 14.1421356237
-0.05*√28800 = -8.48528137424
Step-by-step explanation:
Answer:
16π/9
Step-by-step explanation:
40°/360° = 1/9
40° is 1/9 of a circle
Arc length = 1/9 of circumference = (1/9)2πr = 16π/9
The x intercept is when y=0. Substitute:

Solve for x by factoring.



AND
So therefore, we have our intercepts:
(3,0) & (-7/2,0)
