Differentiate:x^2 + y^2 = 4
You get this:2x + 2yy' = 0
bring the x variable on the other side:2yy' = -2x
Now divide 2y to leave y' by itself:y' = -2x/2y
Answer: y' = -x/y
The given relation is not a implicit solution to the given differential equation.
Answer:
The last choice would be the best because peak is high, and in the histogram, it means it is the highest point in the histogram and data. Hope ths helped!

Answer:
A. 200 Children
B. 280 People
Step-by-step explanation:
Let the total number of people attending the show be Y
Given that 2/7 of the people attending were adults, the number of adults A
A = 2/7 Y
Since the rest were children, the number of children C
C = Y - 2/7 Y
= 5/7 Y
2/5 of the children were boys, the number of boys B
B = 2/5 * 5/7Y
= 2/7 Y
The number of Girls G
G = 5/7 Y - 2/7 Y
= 3/7 Y
Given that there were 120 girls attending the performance
3/7 Y = 120
3Y = 120 * 7
Y = 120 * 7/3
= 280
The number of children in the shown C
= 5/7 * 280
= 200
The number of people at the show is Y = 280
