+ <span>The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)</span>²+2
+ <span>A second point on the parabola is (1,5) and we replace x=1 and y=5. We have:
5</span>=a(1-3)<span>²+2 , so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)</span>²+2
And by checking we have the point (5;5) is on the parabola

The determinant of the above matrix can be obtained as follow :
|2 3|
|1 4|
= (2×4) – (1×3)
= 8 – 3
= 5
Thus, the determinant of the metrix is 5

Answer:
4.9 cm
Step-by-step explanation:
The original can has a volume of ...
V = πr²h = π(6 cm)²(10 cm) = 360π cm³
The new can will have the same volume, but a different height:
360π cm³ = πr²(15 cm)
24 cm² = r² . . . . . divide by 15π cm
r = √24 cm ≈ 4.9 cm . . . . . take the square root
The new radius must be about 4.9 cm.
