Answer:
{-3, -1, 1}
Step-by-step explanation:
Zeros refer to x-intercepts. X-intercepts are x values when y = 0. You can tell where they are by looking at where the line passes the x-axis.
Therefore, {-3, -1, 1} are the zeros.
volume(V)=147cm^3
also,
v=1/3×3.14×7^2×h
or, 147×3=3.14×49×h
or, (441)/(3.14×49)=h
or, h=2.87cm
C....................
3.25
according to the systematical theorem it would equal 3.25
