- 8x - 9 = - 21
Add 9 to both sides:
- 8x = - 12
Divide both sides by - 8:
x = -12/-8
x = -3/-2
x = 3/2 OR 1.5
Hope this answer helps :)
What the question? Tell me then I can maybe help
Keeping in mind that x = rcos(θ) and y = rsin(θ).
we know the magnitude "r" of U and V, as well as their angle θ, so let's get them in standard position form.


Answer:
the volume of the cylinder is 904.32 m³
Step-by-step explanation:
Volume of a cylinder is 
π = 3.14
r = 6 units
h - 8 units
Substitute for the values in the volume equation
V = 904.32
X^2+y^2=9
because it is at the origin and radius is 3
