Answer:
y = -.075x +4.89
Step-by-step explanation:
The data set has almost no net slope, so the first equation is the most appropriate. (An absolute value function would be a much better fit.)
y = -.075x +4.89
Answer:
∫₋₃¹ π y⁴ dy
Step-by-step explanation:
If we slice the solid shape, we get circular cross sections or disks. The thickness of each disk is dy. The radius of each disk is x. So the volume of each disk is:
dV = π r² h
dV = π x² dy
Since x = y²:
dV = π y⁴ dy
The total volume is the sum of all the disks from y=-3 to y=1.
V = ∫ dV
V = ∫₋₃¹ π y⁴ dy
