Answer: 169.56 or 170 units^3
Step-by-step explanation:
Volume of a cylinder
3.14(3)^2=28.26*6=169.56
Infinite number of solutions I believe.
Answer:
36 and -12
Step-by-step explanation:
One of the numbers is x then the second number will be 24-x
x = 72 - 3x
x = 36
therefore the second number -12
Answer:
axis of symmetry x=3/2
vertex (3/2, 0)
Step-by-step explanation:
to find the axis of symmetry we use h = -b/2a
where ax^2 + bx+c
h = -(-12)/2(4)
h= 12/8
h = 3/2
the axis of symmetry is x = 3/2
the x coordinate of the vertex is h x=3/2
to find k, the y coordinate of the vertex, substitute x=3/2 into the equation
y=4x^2-12x+9
y=4(3/2) ^2-12(3/2)+9
= 4 (9/4) - 6*3 +9
= 9-18+9
= 0
the vertex (3/2, 0)
Answer:
Mari's mom paid more than Mari's dad.
Step-by-step explanation:
Mari's mom paid $27.39. This is a bit more than $27.
Mari's dad paid $23.79. This is a bit more than $23.
Since $27 > $23, then $27.39 > $23.79.
Mari's mom paid more than Mari's dad.
