Option D: \frac{2}{5} is the x-coordinate

Explanation:

It is given that the coordinates of the line segment are A(3,2) and B(6,11).

Since, the line is partitioned by the point C by the ratio AC : BC = 2 : 3

The distance between the x-coordinates is 3 units.

To determine the value of the x-coordinate for point C, let us divide the value of x-coordinate from the ratio divided by the sum of ratio.

The value of x-coordinate from the ratio is 2.

Sum of the ratio is 2 +3 = 5

Thus,

The x - coordinate = value of x-coordinate from the ratio / Sum of ratio = 2/5

Substituting the values, we have,

The x - coordinate of the Point C = \frac{2}{5}

Thus, Option D is the correct answer.

Let S be the part of the plane 3x+2y+z=3 which lies in the first octant, oriented upward. Find the flux of the vector field F=4i
PtichkaEL [24]

The flux of the vector-field F = 4i + 4j + 1k across the surface S is 63/4. We find out the flux of the vector-field using Green's Theorem.

<h3>Define Green's Theorem.</h3>

Flux form of Green's Theorem for the given vector-field

φ = ∫ F.n ds

= ∫∫ F. divG.dA

Here G is equivalent to the part of the plane = 3x+2y+z = 3.

and given F = 4i + 4j + 1k

divG = div(3x+2y+z = 3) = 3i + 2j + k

Flux = ∫(4i + 4j + 1k) (3i + 2j + k) dA

φ = ∫ (12 + 8 + 1)dA

= 21∫dA

A = 1/2 XY (on the given x-y plane)

3x+2y =3

at x = 0, y = 3/2

y = 0, x = 1

1/2 (1*3/2) = 3/4

Therefore flux = 21*3/4 = 63/4

φ = 63/4.

Is the relation a function? {(14, 9), (15, 8), (8, 7), (1, 9), (15, 2)}<br><br> yes or no?
yulyashka [42]

Answer:

No

Step-by-step explanation:

In order for a group of points to be considered a function, there has to be one exact y value for each x value. In other words, the same x value can't appear twice in the relation. Since 15 appears twice in the relation, it is not a function.
