A=1/3x4/5( basically u just switch the position of 1/3 and change the sign
A=0.27
Answer:
dy/dx = ( 2x - y^2 - 1) / (3y^2 + 2xy + 1).
Step-by-step explanation:
Cross multiply:
x^2 = (x + y)(y^2 + 1)
Using the Chain and Product rules:
Finding the derivative:
2x = (x + y)(2y dy/dx) + (y^2 + 1)(1 + dy/dx)
2x = 2xy dy/dx + 2y^2 dy/dx + y^2 + y^2 dy/dx + 1 + dy/dx
2xy dy/dx + 2y^2 dy/dx + y^2 dy/dx + dy/dx = 2x - y^2 - 1
3y^2 dy/dx + 2xy dy/dx + dy/dx = 2x - y^2 - 1
dy/dx = ( 2x - y^2 - 1) / (3y^2 + 2xy + 1).
Pentagon - 5 sides = 5 x 4 = 20
Hexagon - 6 sides = 6 x 5 = 30
Nanogon - 9 sides = 9
20 + 30 + 9 = 59 IN TOTAL
Answer:
C,B,A
Step-by-step explanation:
I figured this out because 90% of angles go clockwise so all you have to do is this....
C) 61-60 = 1
B) 60-59 = 1
A) 61-59 = 2
Hope this helps! :)
Tell me if I am correct! :)
