Answer:
B
Step-by-step explanation:
Original volume = pi * r^2 * h
New r = 2*r
New h = 3*h
New Volume = pi * (2r)^2 *3*h
New Volume = pi * 4r^2 * 3 *h
New Volume = 4*3 * pi * r^2 + h
Conclusion
The New Volume = 12* the original volume
13) BCA = 90*
CAB = tan^-1 (10/13)
= 37.57*
ABC = tan^-1 (13/10)
= 52.43*
14) ACB = 90*
CBA = tan^-1 (2/3)
= 33.69*
BAC = tan^-1 (3/2)
= 56.31*

Answer:

Step-by-step explanation:
The equation can be rewritten to vertex form, so you can tell the vertex is at (2, -5). The leading coefficient of 2 means the points will be twice as far apart vertically than they would be if the leading coefficient were 1. A couple of points are shown in the attached.
y = 2(x^2 -4x) +3
y = 2(x^2 -4x +4) +3 -8 . . . . . . complete the square
y = 2(x -2)^2 -5 . . . . . . . . . . . . finish putting in vertex form
Answer:
x = 2 | y = 3. ( 2,3 )
Step-by-step explanation:
2(3x + 3y = 15)
6x + 6y = 30
3(4x + 2y = 14)
12x + 6y = 42
- 6x. -6y. -30
6x = 12
÷ 6. ÷6
x = 2
3x + 3y = 15
3(2) + 3y = 15
6 + 3y = 15
-6. -6
3y = 9
÷3. ÷3
y = 3
