A because it’s the only one that makes the best sense
B does not make sense it is the opposite of what ur trying to find
C is not a correct percentage, the correct Percentage would be 53.84%
D which can’t be correct because choice b and c are not correct
When you are looking at a graph, a minimum point would be where the curve is decreasing, then begins to increase. Right at the point where it switches, the slope is a horizontal line, or 0. We can take the derivative is f(x), then look for all the x values where the slope (which is equal to the first derivative) is equal to zero.
f'(x) = 2 * -4sin(2x - pi)
The 2 comes from the derivative of the inside, 2x-pi.
So now set the derivative equal to 0.
-8sin(2x-pi) = 0
We can drop the -8 by dividing both sides by -8.
sin(2x-pi) = 0
This can be rewritten as arcsin(0) = 2x-pi
So when theta equals 0, what is the value of sin(theta)? At an angle of 0, there is just a horizontal line pointing to the right on the unit circle with length of 1. Sine is y/h, but there is no y value so it is just 0. If arcsin(0) = 0, we can now set 2x-pi = 0
2x = pi
x = pi/2
This is a critical number. To find the minimum value between 0 and pi, we need to find the y values for the endpoints and the critical number.
f(0) = -4
f(pi/2) = 4
f(pi) = -4
So the minimum points are at x=0 and x=pi
1296 is the correct answer
Answer:
y^-1 = 3x - 6
Step-by-step explanation:
f(x) = 1/3x + 2
The inverse function is where we swap out y for x and x for y. f(x) represents y, so we will be replacing it with x. Then, we solve and get a new equation for the inverse of y.
x = 1/3y + 2 (subtract 2 from both sides)
x - 2 = 1/3y (multiply by 3 on both sides)
y^-1 = 3x - 6

(E) "cast doubt on the aptness of a description"
Writers will occasionally include a term or phrase in quotation marks to question its veracity. The author of paragraph 2 denigrates the learning theorists by putting the word "experts" in quotation marks because of their "shocking" estimate of canine intelligence.
The answer is not (A). One may contend that the author's use of quote marks conveys surprise or even irritation. (B) is the wrong answer. The term "experts" being surrounded by quotation marks is not a show of "respect," but rather of suspicion.
The answer is not (C). There is no need to doubt the plain usage of the word "experts" in this context, even when the author may have reservations about the theories of the experts. D is likewise a poor choice.
