Answer:
Required A. radious of the cylinder is B. there is no change in radious due to change in height.
Step-by-step explanation:
Given volume of the cylinder is 728, that is we know for a cylinder with height h and radious r, volume V is,
A. To find radious of the cylinder :
which is the required radious.
B. To find change of radious due to change in height :
If the height h of the cylinder change to then radious,
From (1) we get,
Squaring both side we get,
Which shows that change of height dosen't effect on radious.
We have that
<span>the equation
y=-3x</span>²<span> + x -4
the </span><span>real number solutions are the points x intercept of the graph
are the points when y=0
using a graph tool
see the attached figure
</span><span>the graph has no point of intersection with the x axis
</span>therefore
the answer is
there are zero real numbers solutions
