Answer:
yeah it is
y is directly proportional to x
proportionality constant is 9
Answer:
C
Step-by-step explanation:
It can't be B or D, because there is only a difference in the X axis (Meaning it goes either left or right)
It can't be A because 2 is less than 11, so (2, -1) would be left 9 units in relation to (11, -1)
Scalene triangle, this is because there are three sides and all of them are different.
Step-by-step explanation:
Given that:
5π/3
=5/3×180
=240°
This is in the Quadrant III
The value of cot 5π/3 will be given by:
cost θ=1/tan θ
thus
tan θ
=tan 5π/3
=tan 240
=tan (240-180)
=tan 60
using an equilateral triangle with lengths 2 units
then
tan 60=√3/1
tan 60=√3
hence
tan 240=√3
