Answer:
The vertex of the quadratic equation is the point (4,2)
Step-by-step explanation:
we know that
The figure show a vertical parabola open downward
The vertex represent the maximum point of the graph
Looking at the graph
The maximum point of the graph is (4,2)
therefore
The vertex of the quadratic equation is the point (4,2)

<em><u>Question:</u></em>
Ana participated in a charity walk. She raised $0.25 for each 1/2 mile that she walked.The first day Ana walked 11 miles.The second day, she walked 14 miles.How much money did Ana raised?
<em><u>Answer:</u></em>
Ana raised $ 12.5
<em><u>Solution:</u></em>
From given question,
First day walk = 11 miles
Second day walk = 14 miles
<em><u>Let us first calculate the total distance she walked</u></em>
Total distance = first day walk + second day walk
Total distance = 11 + 14 = 25 miles
Thus she walked for 25 miles
Given that,
<em><u>She raised $0.25 for each 1/2 mile that she walked</u></em>
Therefore, for 1 mile we get,
Now calculate for 25 miles
Thus she raised $ 12.5
Solution :
Give that a shark can chase prey about 30 miles per hour.
1 hour = 60 minute
by using unitary method, we will convert miles per hour into miles per minute
in 60 minutes the shark can chase the prey 30 miles
In 1 minute the shark can chase
Hence the shark can chase the prey about 0.5 miles per minute.
