Determine whether or not the vector field is conservative. If it is conservative, find a function f such that f = ∇f. (if the vector field is not conservative, enter dne. ) f(x, y, z) = i + sin(z)j + y cos(z)k.

Answers

If F(x, y, z) = i + sin(z) j + y cos(z) k is conservative, then there exists a scalar function f(x, y, z) such that grad(f) = F, which means

∂f/∂x = 1

∂f/∂y = sin(z)

∂f/∂z = y cos(z)

Integrating each each of these equations gives

∫ ∂f/∂x dx = ∫ dx   ⇒   f(x, y, z) = x + α(y, z)

∫ ∂f/∂y dy = ∫ sin(z) dy   ⇒   f(x, y, z) = y sin(z) + β(x, z)

∫ ∂f/∂z dx = ∫ y cos(z) dz   ⇒   f(x, y, z) = y sin(z) + γ(x, y)

It follows that α(y, z) = y sin(z) and β(x, z) + γ(x, y) = x + C where C is a constant. So

f(x, y, z) = x + y sin(z) + C

and F is indeed conservative.

On interval 0 ≤ x < 2π, where are the x-intercepts of y = cos(2x)? startfraction pi over 2 endfraction and startfraction 3 pi over 2 endfraction 0, π, and 2π startfraction pi over 2 endfraction, pi and startfraction 3 pi over 2 endfraction.

Answers

The x-intercepts of y = cos(2x) in the interval 0 ≤ x < 2π are π/4 and 7π/4

The x-intercepts of y = cos(2x) are gotten when y = 0.

So, y = cos(2x)

cos(2x) = 0

Taking inverse cos of both sides, we have

cos⁻¹cos(2x) = cos⁻¹(0)

2x = π/2

Dividing both sides by 2, we have

x = π/4

So, the other angle in the range 0 ≤ x < 2π is x = 2π - π/4 = 7π/4

So, the x-intercepts of y = cos(2x) in the interval 0 ≤ x < 2π are π/4 and 7π/4

Which shows the correct values for the variables in the table? a = 18, b = 34, c = 65 a = 34, b = 18, c = 68 a = 34, b = 68, c = 47 a = 47, b = 18, c = 68.

Answers

The values of a, b, and c from the table are 34, 18, and 68 respectively.

From the given table, the following equations are true;

number of subscribers above $25000 + number of those not subscribing above $25000 = 47

Set theory

Substituting the values:

a + 13 = 47

a = 47 - 13

a = 34

Similarly;

b + 55 = 73

b = 73 - 55

b = 18

Also, c = 13 + 55

c = 68

Hence the values of a, b, and c from the table are 34, 18, and 68 respectively.
