Answer: desmos. com
Step-by-step explanation: desmos is a good online graphing calculator to graph y= 6x-16.5
Does y equal three? I get that answer from the Pythagorean theorem with 3,4,5.
Try that.
Slope = (y₂ - y₁)/(x₂ - x₁)
(-2, -1)
x₁ y₁
(3, 4)
x₂ y₂
m = (4 + 1)/(3 + 2)
m = (5)/(5)
m = 1
The slope of the points is 1.
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
