Answer:
Step-by-step explanation:
x=55. Explanation: If x varies inversely as y , then that means: y=kx. Let's multiply both sides of the equation by x to find k . k=xy.
Is this finding area or what is it?
It is 270. Multiply 18 by 12 for the square portion of the shape. Then multiply 18 by 6 for the right triangle. I got 6 by subtracting the bottom line by the top line of the quadrilateral.
Let x be the distance (in feet) along the road that the car has traveled and h be the distance (in feet) between the car
and the observer.
(a) Before the car passes the observer, we have dh/dt < 0; after it passes, we have dh/dt > 0. So at the instant it passes the observer we have
dh/dt = 0, given that dh/dt varies continuously since the car travels at a constant velocity.
