let length of the rectangle be l
length is 6 cm longer than the width, w
l = w + 6
perimeter of rectangle is 72 cm
= 2l + 2w
substitute l = w + 6
2(w+6) + 2w = 72
4w + 12 = 72
4w = 60
x = 15
ans is C. 15 cm

Answer:
a) Depth changing rate of change is , When the water is 6 meters deep
b) The width of the top of the water is changing at a rate of , When the water is 6 meters deep
Step-by-step explanation:
As we can see in the attachment part II, there are similar triangles, so we have the following relation between them , then .
a) As we have that volume is , then , so we can derivate it due to the chain rule, then we clean this expression for and compute with the knowns , is the depth changing rate of change when the water is 6 meters deep.
b) As the width of the top is , we can derivate it and obtain The width of the top of the water is changing, When the water is 6 meters deep at this rate
Answer:
Step-by-step explanation:
2/3x(-4)=20
2/3x*4=20
8/3x=20
8/3x/8/3= 20/8/3
