Step-by-step explanation:
Notice that:
15x = 5 * 3x and 10y = 5 * 2y.
Since there is a common factor of 5,
we can take out the factor.
=> 15x + 10y = (5)(3x) + (5)(2y) = 5(3x + 2y).
C.
he starts 6500 ft up do that's the b in y=mx+b.
the m is -250 because that's the rate, and it's negative because he's going down.
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
