Answer:
The area is changing by the rate of 44.62 meters per sec.
Step-by-step explanation:
Let x be the side of the square and r be the radius of the circle,
Then, the area outside the circle but inside the square is,
V = Area of square - area of circle,
∵ Area of a square = side² and area of a circle = (radius)²,
Thus,
Differentiating with respect to t ( time )
We have,
x = 20 meters, r = 3 meters,
4(3)-6(-2)
12- -12
12+12
24
That's the easily recognizable factored form of
the difference between two squares. Before
factoring, it was
x² - 16 .
From the given graph, the slope of the graph represents Miranda's speed and is given by:
From the equation for Claude, it can be seen that the speed of Claude is 55mph
Therefore, <span>Claude's speed is greater since 55 > 50.</span>
