Percent means parts out of 100 so
40%=40/100=4/10
'of' can be translated as multiply
50 times 4/10=200/10=20
$20=lunch

Quick answer: 1756
Step-by-step explanation:
I'll be commenting on my own answer with an easy to understand explanation on how I got this answer
Answer:
8 units because the diameter is the side to side length of the circle so when you count it you get 8 units.
<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>
<em><u>Solution:</u></em>
<em><u>Given is:</u></em>

We have to find the vertex and axis of symmetry
<em><u>The general equation is given as:</u></em>

Comparing with given equation,
a = 2
b = 0
c = -1
<em><u>The axis of symmetry is given as:</u></em>


Thus axis of symmetry is 0
The x coordinate of the vertex is the same
x coordinate of the vertex = 0
h = 0
The y coordinate of the vertex is:
k = f(h)
k = f(0)

Thus, y coordinate of the vertex is -1
Therefore, vertex is (0, -1)
