The first equation
6x^2 -18x-24=0
-the graph opens up
6(x^2 -3x -4)=0
6(x^2 -3x +9/4-4-9/4)=0
6(x-3/2)-25x6/4=
6(x-3/2)-75/2
-Vertex is at (3/2, -75/2)
-Axis of symmetry is x=3/2
Second equation
3r^2 -16r -12=0
-the graph opens up
...
Answer:
320/4=8 8 tens /4 tens =2
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ( where r is the radius )
Here r = 3, thus
V =
π × 3³
=
π × 27 = 4π × 9 = 36π in³ → b
