Answer:
Step-by-step explanation:
To do this, we must use the unit circle. At the angle 
the coordinate pair is (
, 
) and the hypotenuse is 1
Now that we know these we can start using the trig functions
sin = y
cos = x
tan = 
And the other functions would be the reciprocal of these
csc = 
sec = 
cot = 
This would mean that
sinx =
cosx =
tanx =
or 
if you're supposed to rationalize your denominators
cscx = 2
secx = 
or 
cot = 
The wrong statement: The volume or the smaller cone cannot be determined because its height is unknown.
We already know that the larger cone has a height of 8 cm and that the smaller cone is just 1/4 of 8 cm.
8×1/4 = 2 cm.
You can still find its volume by using the formula 1/3πr^2.
Answer:
x = 10
Step-by-step explanation:
Proof: If a line is parallel to one side of the triangle, then it divides the other two sides proportionally.
6/9 = x/15
9x = 90
x = 10
Answer:
The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero). y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.
