Let F (x; y) = xy2i + x2y j. Evaluate ∫F.ds (from c to [infinity]) where C is the upper half of the circle of radius 1 centered

77julia77 [94]

Answer:

The integral $\int F \bullets ds$ is 0.

Step-by-step explanation:

A parameterization of curve C can be:

X (t) = cost 0 <= t <= pi

Y (t) = sint 0 <= t <= pi

r (t) = costi + sintj

r '(t) = -sinti + costj

$Fds = [-costsin^3t + sintcos^3t] dt$

The integral $\int F \bullets ds$ is given by:

$\int _0^{\pi }\left[-costsin^3t + sintcos^3t dt\right]dt$

$= \int _0^{\pi }-sin ^3tcostdt + \int _0^{\pi }sintcos^3tdt = 0$

The following table shows the number of feet a helicopter flies above the ground as a function of time:

Morgarella [4.7K]

Using a linear function and applying the concept of the x-intercept, it is found that the correct option is:

(18, 0); the time it takes for the helicopter to reach the ground

---------------------

A linear function has the following format:

$y = mx + b$

In which:

m is the slope, which is the rate of change.
b is the y-intercept, which is the value of y when x = 0.

In this problem:

The initial height is of 18 feet, thus $b = 18$ .

After 2 seconds, the height is 16 feet, that is, in 2 seconds the height decayed 2 feet, thus $m = -\frac{2}{2} = -1$

The function for the <u>height after x seconds</u> is:

$y = -x + 18$

The x-intercept is the value of x when y = 0, that is, the time it takes for the helicopter to reach the ground. Then:

$-x + 18 = 0$

$-x = -18$

$x = 18$

Thus, point (18,0), and the correct option is:

(18, 0); the time it takes for the helicopter to reach the ground
