The answer would be 36 because you just plug 3 in for x
Answer:
cm/sec.
Step-by-step explanation:
We have been given that a particle in the first quadrant is moving along a path described by the equation
such that at the moment its x-coordinate is 2, its y-coordinate is decreasing at a rate of 10 cm/sec. We are asked to find the rate at which x-coordinate is changing at that time.
First of all, we will find the y value, when
by substituting
in our given equation.







Since the particle is moving in the 1st quadrant, so the value of y will be positive that is
.
Now, we will find the derivative of our given equation.

We have been given that
,
and
.







Therefore, the x-coordinate is increasing at a rate of
cm/sec.
Answer:
Rate of change = -0.2
Step-by-step explanation:
Given:
(-3, 3.6) and (5, 2)
Required:
Rate of change
Solution:
Formula for rate of change = change in y/change in x = 
Let,
(-3, 3.6) = (x_1, y_1)
(5, 2) = (x_2, y_2)
Plug in the values into the equation:
Rate of change = 
Rate of change =
= -0.2
Answer:
ANSWER IS ........... C
Step-by-step explanation:
X=-20 2/5,x=-20.4 so it’s x=102/5
