0-4 stay on the floor 5-9 climb the vine this can determine place value is greater or less
Answer:
(-3,-1)
Step-by-step explanation:
6x-12y=-6
6x=12y-6
x=2y-1
9(2y-1)-6y= -21
18y-9-6y=-21
12y= -12
y=-1
6x-12(-1)=-6
6x+12= -6
6x=-18
x=-3
Answer:
One root is 90 degrees or π/2 radians.
Drawing a graph we get all the roots:
nπ and π(n - 1/2)
Step-by-step explanation:
Sin^3A.cos A + Cos^ 3 A = Cos A
Divide through by cos A
sin^3A + cos^2A = 1
sin^3 A = 1 - cos^2 A
sin^3 A = sin^2 A
sin A = 1
So one root is A = 90 degrees or π/2 radians.
Checking this result:
(sin 90^3 * cos 90 + (cos 90)^3 = 1 * 0 + 0 = 0
cos 90 = 0
So this is correct..
Quadrant 2 or 4. All points in quadrant 1 are both positive, all points in quadrant 3 are both negative.
