Answer:
-1.
Step-by-step explanation:
1) according to the DeMoivre's theorem:
2) if cos(π)=-1 and sin(π)=0, then cosπ+i*sin(π)=-1.
The volume of B is twice that of A
if Vb=2hpir^2
and Va=hpir^2
compare
2hpir^2
hpir^2
twic as big
Volume of B is 2 times that of Volume of A
The interval over which the given quadratic equation decreases is: x ∈ (5, ∞).
<h3>How to find the interval of quadratic functions?</h3>
Usually a quadratic graph function decreases either when moving from left to right or moving downwards.
In the given graph, we can see that the coordinate of the vertex is (5, 4) after which the curve goes in the downward direction.
Thus, for the values of x greater than 5, the function decreases and so we conclude that the interval in which the quadratic equation decreases is: (5, ∞).
