The correct answer is option (c) W = 0.

Given information :F = 6xi + 6yj + 6zk; P1(4, 3, 5), P2(5, 6, 7)The formula for work done by the conservative force is given by: W = U(P2) - U(P1)Where U(P) is the potential energy at point P. The force is conservative. Hence, work done is independent of path and is equal to the difference in potential energy between points 1 and 2.To find the potential energy U at any point, we use the formula: U(x, y, z) = - ∫F.dr where F is the force, and dr is the infinitesimal displacement vector.

To find the potential difference between two points, we integrate the formula: W = - ∫F.dr over a path between those two points, P1 and P2.Now we will find the potential energy at points 1 and 2.∴U(P1) = -∫F.drbetween the limits (4,3,5) and (5,6,7)Let us take the path from P1 to P2 along the straight line. Then the position vector of the path is:r = (5 - 4) i + (6 - 3) j + (7 - 5) k = i + 3j + 2k.dr = dx i + dy j + dz k= i dx + j dy + k dz = i dt + 3j dt + 2k dt = (i + 3j + 2k) dt∴∫F.dr= ∫6x i . (i + 3j + 2k) dt + ∫6y j . (i + 3j + 2k) dt + ∫6z k . (i + 3j + 2k) dt= ∫6x dt + 3 * 6y dt + 2 * 6z dt= (6x + 18y + 12z) |_P1^P2= (6 * 5 + 18 * 6 + 12 * 7) - (6 * 4 + 18 * 3 + 12 * 5)= 30 + 108 + 84 - 24 - 54 - 60= 84Thus, U(P2) - U(P1) = 0 - 84 = -84. Hence, work done = -(-84) = 84Option (d) W = 180 is incorrect as the value of work done is 84.

Answer:

[tex]0.80i +0.2j[/tex]

Step-by-step explanation:

The projection of u on v is expressed as;

[tex]proj_{v} u = \dfrac{u*v}{|v|^2} * v[/tex]

Given

u=1.6i+3.3j

v=-2.1i-.5j

u*v = (1.6i+3.3j )*(-2.1i-0.5j )

u*v = 1.6i(-2.1i) + 3.3j(-0.5j)

u*v = -3.36 - 1.65

u*v = -5.01

|v|² = (√(-2.1)²+(-0.5)²)²

|v|² = (-2.1)²+(-0.5)²

|v|² = 4.41+0.25

|v|² = 4.66

Substitute into the formula;

[tex]= \frac{1.71}{-5.01} * (-2.1i - 0.5j)\\= -0.3413 (-2.1i - 0.5j)\\= 0.8i + 0.17j\\= 0.80i +0.2j[/tex]

The inverse Laplace transform of f(t) is given by f(t) = t - 98δ(t - 2) - 15.

To find the inverse Laplace transform of F(s) = 8s^2 - 98e^(2s) - 15, we can use the linearity property and the table of Laplace transforms. Let's break down the expression into three terms.

The inverse Laplace transform of 8s^2 is obtained by looking up the corresponding entry in the table of Laplace transforms. From the table, we find that the inverse transform of s^2 is t.

The inverse Laplace transform of -98e^(2s) can also be found in the table. The entry for e^(as) is δ(t - a), where δ(t) represents the Dirac delta function. Therefore, the inverse transform of -98e^(2s) is -98δ(t - 2).

Lastly, the inverse Laplace transform of -15 is simply -15.

By applying the linearity property, we can add up the individual inverse transforms:

Inverse Laplace transform of F(s) = t - 98δ(t - 2) - 15.

Therefore, the inverse Laplace transform of f(t) is given by f(t) = t - 98δ(t - 2) - 15.

No, if we reject a null hypothesis at the 10% significance level, it does not necessarily mean that we will also reject it at the 5% significance level.

Explanation:

Rejecting or not rejecting a null hypothesis depends on the level of statistical significance chosen for the hypothesis test. The significance level, often denoted as α, determines the threshold for accepting or rejecting the null hypothesis.

When we reject a null hypothesis at the 10% significance level, it means that the p-value associated with the test is less than 0.10. This suggests that the observed data provides strong evidence against the null hypothesis, and we can reject it.

However, the 5% significance level is a more stringent criterion. If we test the same null hypothesis at a lower significance level (α = 0.05), we require stronger evidence to reject the null hypothesis. Therefore, if the p-value is greater than 0.05 but less than 0.10, we would fail to reject the null hypothesis at the 5% significance level.

In summary, rejecting the null hypothesis at the 10% significance level does not guarantee its rejection at the 5% significance level. The decision to reject or fail to reject the null hypothesis depends on the chosen significance level and the corresponding p-value obtained from the hypothesis test.

The projection of the region D onto the xy-plane is an ellipse centered at the origin, with a major axis length of 4 and a minor axis length of 2.

To find the projection of the region D onto the xy-plane, we need to determine the intersection curve of the two paraboloids in the xyz-space. Setting the equations of the paraboloids equal to each other, we have:

3x^2 + y^2 = 16 - x^2.

Combining like terms, we get:

4x^2 + y^2 = 16.

This equation represents an ellipse in the xy-plane. To visualize the projection, let's rewrite the equation in terms of standard form:

(x^2)/4 + (y^2)/16 = 1.

Comparing this equation to the standard equation of an ellipse, (x^2)/(a^2) + (y^2)/(b^2) = 1, we can see that the major axis of the ellipse is along the y-axis, with a length of 4, and the minor axis is along the x-axis, with a length of 2.

Therefore, the projection of the region D onto the xy-plane is an ellipse centered at the origin, with a major axis length of 4 and a minor axis length of 2. The shape of the ellipse will have its major axis along the y-axis and its minor axis along the x-axis.

In summary, the projection of the region D onto the xy-plane is an ellipse centered at the origin, with a major axis length of 4 and a minor axis length of 2.

Step-by-step explanation: 210 ft. 2

Answer:

x= 21

y= 3

z= 21

Step-by-step explanation:

Let the center be O,

=> Triangle AOD is an Isosceles triangle so AO≅DO, "21 = x"

=> Line AC is divided in two equal parts by the center so if AO= 21 then

    7y = 21, and thus "y = 3"

=> BOC is also an Isosceles triangle so CO ≅ BO, if CO = 21 (7y → 7*3) then so will be BO. Therefore "z = 21"

vertex at (-4,-5)

Answer:

vertex = (- 4, - 5 )

Step-by-step explanation:

The equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = 3x² + 24x + 43 ← factor out 3 from the first 2 terms

  = 3(x² + 8x) + 43

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² + 8x

y = 3(x² + 2(4)x + 16 - 16) + 43

y = 3(x + 4)² - 48 + 43

y = 3(x + 4)² - 5 ← in vertex form

with vertex = (- 4, - 5 )
