Answer:
-4<x<1/3
Step-by-step explanation:
3x²+11x+5<9
3x²+11x-4<0.
First we determine the solutions of
3x²+11x-4=0
Delta=11²-4×3×(-4)=121+48=169=13²
The roots are
x1=(-11-13)/6=-24/6=-4
x2=(-11+13)/6=2/6=1/3
So, we have:
3x²+11x-4=3(x-⅓)(x+4)=(3x-1)(x+4)
So, coming back to our inequality:
(3x-1)(x+4)<0, we note (as we already know) that this condition is satisfied for all those x located between the roots: -4<x<1/3
W(-4,7); X(-2,1); Y(2,1); Z(4,4)
The difference in pay per class is 3, so to even out with he 96, you’d have to take 32 classes, the profit begins at the 33rd

V = <span>πr^2h
We are given the diameter of 2, which means the radius is 1.
V = </span><span>π*1^2 * 3
</span>V = <span>π * 3
So the answer is V = 3</span>π or V ≈ 9.42
