(Area of cross section) x height
So that’s the (area of circle) x height
(Pi x r^2) x h
Answer:
f(x) = -|x - 3| + 2.
Step-by-step explanation:
f(x) = |x| is shaped like a V and the vertex is at (0, 0). f(x) = -|x| is a reflection in the x-axis so will be an inverted V , opening down. f(x) = - |x - 3| will be the -|x| moved 3 units to the right with the vertex at (3, 0). To bring the vertex to (3, 2) it will move upwards 2 units.
So it is f(x) = -|x - 3| + 2.
Answer:
Step-by-step explanation:
Elimination method:
Add these equations to eliminate x:
Then solve for y:
Write down an original equation:
Substitute 4 for y in :
{ and } ⇒
