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.
Three whole numbers are each rounded to the nearest 10.

Four students in ms. Alton's class shared the correlation coefficients derived from their data as follows: student a: r = –0. 87 student b: r = –0. 78 student c: r = 0. 79 student d: r = 0. 86 whose data had the strongest correlation? student a student b student c student d.
Considering the situation described above, the strongest correlation data is the "student a: r = –0. 87."
The correlation of variable is defined to be the strong correlation when the r-value is closer to +1 or -1.
Given that from the available options the r-value that is closer to +1 or -1 is that of student A which has -0.87, therefore, it is concluded that the Student A data had the strongest correlation.
Hence, in this case, it is concluded that the correct answer is option A. "Student A."

Oxygen dissolved in bodies of water make it suitable for aquatic life. Which of the following best describes dissolved oxygen?.
Dissolved oxygen is found in water bodies.
In the aquatic environment, organisms use their gills to perform gaseous exchange. Oxygen dissolves in water and is taken in by these aquatic organisms.
We must note that the dissolution of gases in water is an exothermic process hence the dissolution of oxygen in water occurs at decreased temperatures. Also, a high organic load in water decreases the amount of dissolved oxygen in water.

The correct response is - Option B results in a conflicting impulse to quit reading and to continue, which is the B answer.
What is an Impulse?In classical mechanics, the integral of both a force, F, over the time period over which it acts, t, is referred to as the "impulse." Impulse is a vector quantity since force is one as well. When an item receives an impulse, its linear momentum likewise changes in the opposite direction in an analogous vector.
The impulse function is a very brief pulse that can theoretically never end that is used to assess system dynamics. An impulse function in the real world is a pulse that is substantially shorter than the system's temporal response.
In physics, the term "impulse" is used to characterize or measure the impact of force operating gradually to alter an object's motion. The letter J stands for it, and is typically expressed in Newton-seconds

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 = 47Set theorySubstituting 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.
