The trigonometric functions for this angle are sin(0) = -â2/2, cos(0) = -â2/2, and tan(0) = -1. The measure of the reference angle is not 30° or 60°.
The measure of an angle is the amount of rotation from the starting position to the endpoint of the angle. In this problem, the measure of angle is 0 is 7π/4. This means that the angle has rotated 7π/4 radians from the start position, which is equivalent to 360° - (7π/4)*180/π = 315°.
Therefore, the measure of the reference angle is 45°, because the reference angle is the smallest angle that starts at the x-axis and terminates at the terminal side of the angle, which in this case is 315°. The reference angle is equal to the measure of the angle minus the multiple of 360°, so 45° = 315° - 360°.
The trigonometric functions of sine, cosine, and tangent can be used to evaluate the measure of an angle. The sine of an angle is equal to the ratio of the opposite side of the angle over the hypotenuse of the triangle formed by the angle. In this problem, sin(0) = opposite/hypotenuse = -â2/2, since the angle is 7π/4 radians, or 315°.
The cosine of an angle is equal to the ratio of the adjacent side of the angle over the hypotenuse of the triangle formed by the angle. In this problem, cos(0) = adjacent/hypotenuse = -â2/2, since the angle is 7π/4 radians, or 315°.
The tangent of an angle is equal to the ratio of the opposite side of the angle over the adjacent side of the angle. In this problem, tan(0) = opposite/adjacent = -1, since the angle is 7π/4 radians, or 315°.
In conclusion, the measure of angle is 0 is 7π/4, and the measure of the reference angle is 45°. The trigonometric functions for this angle are sin(0) = -â2/2, cos(0) = -â2/2, and tan(0) = -1. The measure of the reference angle is not 30° or 60°.

the liquid-filled prism is placed in a large tank containing a different liquid and sinks to the bottom of the tank. fx is the magnitude of the buoyant force exerted on the prism by the liquid in the tank when the prism is in orientation x . fy and fz are the buoyant forces for orientations y and z . which of the following correctly ranks the three buoyant forces?
The buoyant force is the upward force on an object submerged in a fluid that is caused by the fluid's pressure.
The magnitude of the buoyant force is equal to the weight of the displaced fluid. Therefore, the correct ranking of the three buoyant forces is fx > fy > fz.
The magnitude of the buoyant force can be calculated using the equation Fb = ρgV, where ρ is the density of the fluid, g is the acceleration due to gravity, and V is the volume of the displaced fluid. For orientation x, the buoyant force fx will be the greatest since the volume of the displaced fluid is the greatest. For orientation y, the buoyant force fy will be the second greatest since the volume of the displaced fluid is second greatest. Finally, for orientation z, the buoyant force fz will be the least since the volume of the displaced fluid is the least.

Draw the graph of y=f(x) and y= 1/f(x) on the same axes.
f) f(x) = -(x+4)²+1
are there any specific steps to get the answers here?
Answer: To graph y = f(x) and y = 1/f(x) on the same axes, you can follow these steps:
First, graph y = f(x) by plotting a few points, such as (-5, -19), (-3, -1), (0, 1) and (5, 19), and then connecting them with a smooth curve.
Then, graph y = 1/f(x) by finding the inverse function of f(x) which will be
1/f(x) = -1/(x+4)²+1
Next, plot a few points on this new function, such as (-5, -1/19), (-3, -1), (0, 1) and (5, 1/19), and then connecting them with a smooth curve.
Finally, make sure that the same x and y scales are used for both graphs, and label the axes and the functions clearly.
It is important to note that as f(x) = -(x+4)²+1, the domain of f(x) is all real numbers but the range is (1, infinity) so the reciprocal will be defined only for the range of f(x) and the domain of 1/f(x) will be (1, infinity)
Also, the graph of y = f(x) will be a parabola opening upwards and y = 1/f(x) will be a parabola opening downwards, both with vertex (-4,1)
The graph of y = -(x+4)²+1 will be a parabola opening upwards and the graph of y = -1/(x+4)²+1 will be a parabola opening downwards.

Step-by-step explanation:
Vertical AsymptotesEquation: x = aA vertical asymptote occurs at the x-value(s) that make the denominator of a rational function zero.Horizontal AsymptotesEquation: y = bIf the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0.If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote (but there is a slant asymptote).If the degree of the numerator is equal to the degree of the denominator, the asymptote is the result of dividing the highest degree term of the numerator by the highest degree term of the denominator.Question 36Given that the function has a horizontal asymptote at y = 7, the degree of the numerator must be equal to the degree of the denominator.
Also, 7 will be the result of dividing the highest degree term of the numerator by the highest degree term of the denominator.
Given that the function has a vertical asymptote at x = 12, the denominator must equal zero when x = 12.
Therefore, a rational function that meets these conditions is:
[tex]f(x)=\dfrac{7x}{x-12}[/tex]
Question 37Given limits:
[tex]\displaystyle \lim_{x \to\infty} k(x)=0[/tex]
[tex]\displaystyle \lim_{x \to-2^+} k(x)=\infty[/tex]
The first limit means that as x approaches positive infinity, the function equals zero. Therefore, the rational function has a horizontal asymptote at y = 0. So the degree of the numerator should be less than the degree of the denominator.
The second limit means that as x approaches -2 from the positive side, the function equals positive infinity. Therefore, the rational function has a vertical asymptote at x = -2.
Therefore, a rational function that meets these conditions is:
[tex]g(x)=\dfrac{1}{x+2}[/tex]
Question 38A removable discontinuity (hole) exists on the graph of a rational function at any input value that causes both the numerator and denominator of the function to be equal.
Therefore, a rational function that meets these conditions is:
[tex]h(x)=\dfrac{x-2}{(x-2)(x+3)}[/tex]
For this rational function the hole is at (2, ¹/₅), as when x = 2, the numerator and denominator are both zero.
The functions can be represented as y = 7x/(x - 7), y = 1/(x + 2) and y = (x - 3)/[(x - 3)(x + 1)]
How to determine the functionsConditions #1
From the question, we have the following parameters that can be used in our computation:
Vertical asymptote, x = 12
Horizontal asymptote, y = 7
A function with the following features
Vertical asymptote, x = a
Horizontal asymptote, y = b
Can be represented as
y = bx/x - a
So, we have
y = 7x/(x - 12)
Conditions #2
Here, we have the following limits
lim x⇒∝ k(x) = 0 and lim x⇒2⁺ k(x) = ∝
This means that:
Vertical asymptote, x = -2
Using the rule in (1), we have
y = 1/(x + 2)
Condition #3
Here, we have
Function with a hole
This implies that the denominator and the numerator have a common factor

What is Quadratic equation?Any equation using the formula ax² + bx + c = 0 is a quadratic equation.
where a, b and c are constants, and x is an unknown variable.
It is called "quadratic" because the variable is squared (in other words, raised to the power of 2).
The most common way to solve a quadratic equation is to factor it into two linear equations, which can then be solved using the methods of linear algebra.
Another way is to use the quadratic formula, which expresses the roots of the equation in terms of the coefficients a, b and c.
It is called a quadratic equation because it can be written in the form
ax² + bx + c = 0
which is the standard form for a quadratic equation.
Examples:
1) x² + 4x – 5 = 0
2) 4x² – 7x + 3 = 0
3) 2x² + 3x – 4 = 0
Therefore , The values of (a + b)(a - b) is a²-b² = (a-b) (a+b) and (x+7)² is x² + 14x+49 = (x+7)(x+7)

3x + 2y=4 3x + 6x=-28
The solution to the equations is x = 20/3 and y = -8
How to determine the solution to the equation?From the question, we have the following parameters that can be used in our computation:
3x + 2y=4
3x + 6y=-28
The above equations is a system of linear equations
So, we can subtract them to eliminate x as follows
4y = -32
Divide both sides by 4
y = -8
Substitute y = -8 in the equation 3x + 2y=4
3x - 16 =4
Evaluate the like terms
3x = 20
So we have
x = 20/3
Hence, the soluton is x = 20/3 and y = -8

define the least common multiple of a and b to be the smallest positive number which is divisible by both a and b. prove that the least common multiple of a and b is ab precisely when a and b are coprime 6
The least common multiple(LCM) of two coprime numbers is their product, ab.
Let a and b be two positive integers, and let LCM(a,b) be the least common multiple of a and b.
By definition, LCM(a,b) is the smallest positive number which is divisible by both a and b.
Now, suppose that a and b are coprime, meaning that there are no positive integers other than 1 that divide both a and b.
Since 1 divides both a and b, and 1 is the smallest positive integer, we know that 1 is the only positive integer that divides both a and b.
Therefore, LCM(a,b) must be divisible by both a and b, and 1 is the only positive integer that divides both a and b.
Thus, LCM(a,b) = ab.
This proves that the least common multiple of a and b is ab precisely when a and b are coprime.

A scientist records the temperature of three different mixtures as -33.625℉, -33 5/6℉, and -33 6/25℉. What is the order from least to greatest temperature of the mixtures?
Answer: To determine the order of the temperature of the mixtures from least to greatest, we need to compare the values of the temperatures in their simplified fractional forms.
-33.625℉ = -33 5/8℉
-33 5/6℉ = -33 5/6℉
-33 6/25℉ = -33 24/100℉
We can compare the fractions by comparing the numerators, if they are the same we can compare the denominators.
So, the order from least to greatest temperature of the mixtures is:
-33 6/25℉ < -33 5/6℉ < -33 5/8℉
It's important to notice that these temperatures are negative.
