9x^2 - y^2 = 1
a.) 18x - 2y dy/dx = 0
2y dy/dx = 18x
dy/dx = 9x/y
b.) y^2 = 9x^2 - 1
y = √(9x^2 - 1)
y' = 9x / √(9x^2 - 1)
c.) substituting y = √(9x^2 - 1) into solution for part a gives
dy/dx = 9x / √(9x^2 - 1)
Thus the two solutions are consistent.
(x,y) -> (-x, y) because the triangle was reflected over the y-axis
Answer:
The first piece is 15 in and the second piece is 21 in
Step-by-step explanation:
5 + 7 = 12
3 ft = 3 x 12 in = 36 in
36 ÷ 12 = 3
5 x 3 = 15 7 x 3 = 21
The first piece is 15 in and the second piece is 21 in
