She has to get around 700 to 800 points in order to get 80%
It would be 600 + 50 + 8 + 0.1 + 0.02 + 0.009

Determine the inequality of the region
The inequality of a region of a sphere is determined using:
Substitute 5 for r
Solving further: <em>The question says only the upper hemisphere is considered.</em>
This implies that:
<em>So, the equation is:</em>

<h3>Answer : (-2,11)</h3>

<h3>Known that</h3>
y = -2x² - 8x + 3
════════════════════
<h3>Way to do + explanation</h3>
#First, find the x coordinate first by using the formula of -b/2a
x = -b/2a = -(-8)/2(-2) = 8/-4 = -2
#After getting the x, find the y
y = -2(-2)² - 8(-2) + 3
y = -2×4 +16 + 3
y = -8 + 16 + 3
y = 11
So the vertex is
(-2,11)
