Answer:
17/24
Step-by-step explanation:
2 5/6 =

= 
The description expresses three points which can be used for a standard form equation. The vertex is stated to be (0,0) and is a maximum; two other points are (-21,-74) and (21,-74)
The equation for vertex form of a parabola:
y=a(x-h)^2+k
vertex (h,k)
thus our equation will be:
y=a(x-0)^2+0
thus
y=ax^2
using one of the points, the value of a will be:
-74=a(21)^2
a=-74/441
thus the equation will be:
y=-74/441x²
Answer:
263.9 cm^3 to nearest tenth.
Step-by-step explanation:
V = 1/3 π r^2 h
= 1/3 π 6^2 7
= 12 * 7 π
= 84π
= 263.8938
