The correct question is
<span>Rui is a professional deep water free diver. His altitude (in meters relative to sea level), xxx seconds after diving, is modeled by: d(x)=1/2x^2 -10x What is the lowest altitude Rui will reach?
we have that
</span>d(x)=(1/2)x² -10x
we know that
the function is quadratic (a parabola)
so
<span>the lowest altitude (depth) is the vertex
</span>
using a graph tool
see the attached figure
the vertex is the point (10,-50)
that means
His altitude (in meters relative to sea level), 10 seconds after diving is 50 meters under the sea level
therefore
the answer is
<span>the lowest altitude is 50 meters under the sea level</span>

Answer:
The number of customer needed to achieve is 34
Step-by-step explanation:
Given as :
The number of customer per hour = 8
The time taken = 8 hours
The rate of increase = 20 %
Let The increase in number of customer after 20 % increment = x
So , The number of customer after n hours = initial number ×
or, The number of customer after 8 hours = 8 ×
or, The number of customer after 8 hours = 8 × 4.2998
∴The number of customer after 8 hours = 34.39 ≈ 34
Hence The number of customer needed to achieve is 34 answer
