The volume of a cone is V = (1/3)*pi*h*r^2
V = (1/3)*3.14*8*12^2 = 1206 cu.cm
the right answer is actually 30,60,90, I got the answer right on the test
Answer:
x=1/2, x=-3
Step-by-step explanation:
2x^2+5x-3 = 0
(2x^2+6x)+(-x-3) = 0
2x(x+3)+-1(x+3) = 0
(2x-1)(x+3)=0
2x-1=0, x+3=0
x=1/2, x=-3
From the graph,

But this one is inequality so you gotta remember this:
When y > x/2+2
- The shade/region is above the graph itself.
When y < x/2+2
- The shade/region is below the graph.
Therefore, the inequality as shown in the picture is
