Add a picture of the options so I can help point out which one it’d be for you.
I believe it's C because it compares her hair with her classmates.
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:
261.8
Step-by-step explanation:
pi x 5 squared x 10/3 = 261.8 for a cone
Divide 3/4 which is 0.75 and then multiply that by 20 which is 15 Final answer:15
