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.
Arrange the tiles to show the sequence of events in the development of the theory of evolution.
According to the principle of natural selection, organisms breed more young than they can withstand in their surroundings.
What is Theory of Evolution?Those who are more physically capable of surviving, maturing, and reproducing. On the other hand, those who lack this fitness either do not live long enough to reproduce or have fewer children than their counterparts.
Because the "fittest" organisms—those most adapted to their environment—are the ones that reproduce most successfully and are most likely to pass on their qualities to the next generation, natural selection is sometimes summed up as "survival of the fittest."
This means that if an environment changes, qualities that help people survive in it will eventually adapt, or develop. Natural selection was a potent force.
Therefore, According to the principle of natural selection, organisms breed more young than they can withstand in their surroundings.

The barry family invited 100 relatives to their christmas party. 90 guests had italian heritage, 80 had german heritage and 75 had swiss heritage. What is the minimum number of people who claimed ancestry from all three heritages?.
Answer:
45
Explanation:
The minimum number of people who claimed ancestry from all three heritages is : 45
Given that there are 100 relatives
let's assume that 1 relative = 1 room
100 relatives = 100 rooms
Number of relatives with Italian heritage = 90
Number of relatives with German heritage = 80
Number of relatives with swiss heritage = 75
Step 1 :
Fill up the first 90 rooms with Italian heritage relatives
Fill up the remaining 10 rooms with 10 Relatives with German heritage
Step 2 :
Distribute the remaining 70 relatives with German heritage into 70 rooms out of the 90 rooms already occupied by the relatives with Italian heritage
Step 3:
Distribute the 75 relatives with swiss heritage into the 20 rooms occupied by Italian heritage relatives only and 45 rooms occupied by both German and Italian relatives and into the 10 rooms occupied by the German heritage relatives
Therefore we can conclude that the minimum number of people who claimed ancestry from all three heritages is : 45

The data that were collected are displayed in the scatterplot and the least-squares regression line was calculated. One student with 2 absences has a gpa of 1. 8. This point is circled on the graph. What effect does the circled point have on the slope and y-intercept of the least-squares regression line? this point will increase the value of the slope and increase the value of the y-intercept. This point will increase the value of the slope and decrease the value of the y-intercept. This point will decrease the value of the slope and increase the value of the y-intercept. This point will decrease the value of the slope and decrease the value of the y-intercept.
Based on the information given, the effect of the circled point on the correlation will be D. This point will decrease the value of the slope and decrease the value of the y-intercept.
What is correlation?From the complete information, it can be noted that the effect of the circled point on the correlation is that the correlation will be weakened because the point falls outside the data pattern.

Let g be the function given by g(x)=x2ekx, where k is a constant. For what value of k does g have a critical point at x=23?.
It looks like we have
[tex]g(x) = x^2 e^{kx}[/tex]
If x = 23 is a critical point of g(x), then
[tex]g'(x) = 2x e^{kx} + kx^2 e^{kx} = (kx^2 + 2x) e^{kx}[/tex]
[tex]\implies g'(23) = (23^2k + 46) e^{23k} = 0[/tex]
[tex]e^{23k}[/tex] is positive for all k, so we're left with
23² k + 46 = 0
23² k = -46
k = -46/23²
k = -2/23

Global warming is known to be the outcome of the internal climate variability, or alterations in the relationship or interaction between the oceans and the atmosphere.
Due to the above, there is gradual/fast increase in temperatures due to the fact that they are getting their heat from deep within the oceans.

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
