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.
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.
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.

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.
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.

Answer: The correct answer is D. Ask a question that can be answered by making observations.
Explanation:
Basically, in order to develop a testable hypothesis, scientists must adhere to the guidelines of the scientific method.
The scientific method is usually understood to be a so-called hypothetical-deductive method, the core of which is to make hypotheses based on observations or measurements, to make predictions based on them and to check the validity of predictions by repeated experiments. More generally, the scientific method is a general way of obtaining solid knowledge, using many means of proof, both empirical and theoretical, to achieve certainty. The scientific method is a widely recognized tool in the scientific community for seeking objectivity, reliability and transparency in research.
