Y = square root of x, dx/dt = 12 , find dy/dt when x = 9

dy/dt=2

Step-by-step explanation:

y=√x

dy/dx=1/(2√x)

when x=9

dy/dx=1/(2√9)=1/(2×3)=1/6

dy/dx=(dy/dt)/(dx/dt)

1/6=(dy/dt)/12

dy/dt=1/6×12=2

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
