Find the point (x, y) on the unit circle that corresponds to the real number t. ON THE BLANK WRITE DOWN sqrt(2) for √2 or sqrt(3) for √3. t = 5????/6 the corresponding (x,y) is
The point (x, y) on the unit circle that corresponds to the real number t = 5π/6 is (-√3/2, 1/2).
The point (x, y) on the unit circle that corresponds to the real number t can be found using the following equations:
x = cos(t)
y = sin(t)
Since t = 5π/6, we can plug this value into the equations to find x and y:
x = cos(5π/6) = -√3/2
y = sin(5π/6) = 1/2
Therefore, the point (x, y) on the unit circle that corresponds to the real number t = 5π/6 is (-√3/2, 1/2).
Note: The unit circle is a circle with a radius of 1 that is centered at the origin (0, 0) of the coordinate plane. The x-coordinate of a point on the unit circle corresponds to the cosine of the angle formed by the positive x-axis and the radius connecting the origin to the point, while the y-coordinate corresponds to the sine of this angle.

The critical numbers of f''(x) are 5 and 4.5.
To find the critical numbers of f(x), we need to first find the derivative of f(x) and then set it equal to zero. The derivative of f(x) is f'(x) = 4x3 - 57x2 + 270x. Setting this equal to zero gives us:
4x3 - 57x2 + 270x = 0
Factoring out an x gives us:
x(4x2 - 57x + 270) = 0
Using the quadratic formula, we can find the values of x that make this equation true:
x = (-(-57) ± √((-57)2 - 4(4)(270)))/(2(4))
x = (57 ± √(3249 - 4320))/8
x = (57 ± √(-1071))/8
x = (57 ± i√1071)/8
Since the values of x are complex, there are no real critical numbers of f(x).
The second derivative of f(x) is f''(x) = 12x2 - 114x + 270. Setting this equal to zero gives us:
12x2 - 114x + 270 = 0
Using the quadratic formula, we can find the values of x that make this equation true:
x = (-( -114) ± √((-114)2 - 4(12)(270)))/(2(12))
x = (114 ± √(12996 - 12960))/24
x = (114 ± √36)/24
x = (114 ± 6)/24
x = 5 or x = 4.5
The table below shows the critical numbers of f(x) and f''(x) in ascending order:

\[ \begin{array}{l} f(x)=2 x^{2}+5 \\ f-1(x)= \end{array} \] fx domain \( f x \) range \[ \begin{array}{l} f(x)=\frac{1}{2} x+4 \\ g(x)-6 x-2 \\ f \circ g(x)= \\ g \circ f(x)= \\ f(x)=\frac{1}{x-9} \\
The f(g(x)) is equal to 72x^2+48x+9 and g(f(x)) is equal to 3x+22.
To provide an accurate answer, it's important to first understand what the question is asking for. From the given information, it appears that there are several different parts to this question, so I will address each one individually.
1. Finding f-1(x)
To find the inverse of f(x), we can switch the x and y values and solve for y.
\begin{align*}
f(x) &= 2x^2+5 \\
y &= 2x^2+5 \\
x &= 2y^2+5 \\
2y^2 &= x-5 \\
y &= \sqrt{\frac{x-5}{2}} \\
f^{-1}(x) &= \sqrt{\frac{x-5}{2}}
\end{align*}
Therefore, f-1(x) is equal to √((x-5)/2).
2. Determining fx domain and range
The domain of f(x) is all real numbers since there are no restrictions on the input value x. However, the range of f(x) is limited by the fact that 2x^2+5 is always greater than or equal to 5. Therefore, the range of f(x) is [5,∞).
3. Finding f(g(x)) and g(f(x))
To find f(g(x)), we first need to substitute g(x) into f(x) wherever x appears:
\begin{align*}
f(g(x)) &= 2(g(x))^2+5 \\
&= 2(6x+2)^2+5 \\
&= 72x^2+48x+9
\end{align*}
To find g(f(x)), we first need to substitute f(x) into g(x) wherever x appears:
\begin{align*}
g(f(x)) &= 6f(x)-2 \\
&= 6\left(\frac{1}{2}x+4\right)-2 \\
&= 3x+22
\end{align*}
Therefore, f(g(x)) is equal to 72x^2+48x+9 and g(f(x)) is equal to 3x+22.
4. Explaining f(x)=1/(x-9)
The function f(x)=1/(x-9) is a rational function with a vertical asymptote at x=9. This means that as x approaches 9 from either direction, the function values become increasingly large (either positive or negative infinity).
The domain of f(x) is all real numbers except for x=9 (since dividing by zero is undefined). The range of f(x) is all real numbers except for zero (since 1/0 is undefined).I hope this helps! Let me know if you have any further questions.

Let X be a random variable with EXP < and let Y = [X]. Suppose that X has a Lebesgue density symmetric about 0. Show that X and Y are uncorrelated, but they are not independent.
The value of Y is not independent of the value of X, and so X and Y are not independent.
Let X be a random variable with EXP <∞ and let Y = [X]. Since X has a Lebesgue density symmetric about 0, we know that E[X] = 0. Therefore, E[XY] = E[X[X]] = E[X²] = Var[X] + E[X]² = Var[X].
Since X and Y are uncorrelated, we have E[XY] - E[X]E[Y] = 0, which implies that E[XY] = E[X]E[Y] = 0*E[Y] = 0. Therefore, X and Y are uncorrelated.
However, X and Y are not independent because the value of Y depends on the value of X. For example, if X = 1.5, then Y = 1, but if X = -1.5, then Y = -2. Therefore, the value of Y is not independent of the value of X, and so X and Y are not independent.

a) sin B = y/r = -1/5sqrt(2) and cos B = x/r = 7/5sqrt(2) (b) Since sin B is positive and cos B is negative, we found that angle B belongs in Quadrant II.
Given that cot a = 7, we know that tan a = 1/7. Since tan a = y/x, we can let x = 7 and y = -1 (since a is in Quadrant III and both x and y values are negative in this quadrant).
Using the Pythagorean Theorem, we can find r:
r = sqrt(x^2 + y^2) = sqrt(7^2 + (-1)^2) = sqrt(50) = 5sqrt(2)
Now we can find sin B and cos B:
sin B = y/r = -1/5sqrt(2)
cos B = x/r = 7/5sqrt(2)
We can use the double angle formulas for sine and cosine, sin B and cos B: sin B = sin(Phi - a) = sin Phi cos a - cos Phi sin a = (0)(-7/25) - (1)(-24/25) = 24/25 cos B = cos(Phi - a) = cos Phi cos a + sin Phi sin a = (1)(-7/25) + (0)(-24/25) = -7/25.
Since sin B is positive and cos B is negative, we know that angle B is in Quadrant II.

2h) What factors would be a better choice to use to simplify the square root of 48? Why should you choose those
factors and not any other pair?
Answer:
2g) Letty cannot use the factors 4 and 12 to simplify the square root of 48 using the Product Property of Square Roots because 4 is a perfect square, but 12 is not. The Product Property of Square Roots only applies to factors that are both perfect squares.
2h) A better choice to simplify the square root of 48 would be to use the factors 16 and 3. This is because 16 is a perfect square and is a factor of 48, which means it can be taken out of the radical completely. The remaining factor is 3, which cannot be simplified any further since it is not a perfect square. Therefore, the square root of 48 can be simplified to 4 times the square root of 3. It is important to choose 16 and 3 as the factors and not any other pair because 16 is the largest perfect square factor of 48, and 3 is the remaining factor after taking out 16 that cannot be simplified any further.
2g) These factors (4 and 12) are not the best choice to simplify the square root of 48 because 4 is a perfect square, but 12 is not.
2h) a better choice to simplify the square root of 48 would be to use the factors 16 and 3. This is because 16 is the largest perfect square factor of 48, which simplifies the radical the most.
Now, Using the Product Property of Square Roots, we can simplify the square root of 48 as :
√48 = √(4 x 12)
However, these factors (4 and 12) are not the best choice to simplify the square root of 48 because 4 is a perfect square, but 12 is not.
Hence, We want to simplify the radical by finding the largest perfect square that is a factor of 48.
For this, we can break down 48 into its prime factors:
48 = 2 x 2 x 2 x 2 x 3
Then, we group the prime factors into pairs of the same number:
48 = (2 x 2) x (2 x 2) x 3
This gives us two perfect squares, 4 and 16.
Hence, We can simplify the square root of 48 by using the largest perfect square factor, which is 16:
√48 = √(16 x 3)
√48 = √16 x √3
√48 = 4√3
Therefore, a better choice to simplify the square root of 48 would be to use the factors 16 and 3.
This is because 16 is the largest perfect square factor of 48, which simplifies the radical the most.

8:02 PM Wed Feb 22 L Allie Stevenson's practice S.12 Properties of logarithms: mixed review Rewrite the logarithmic expression as a single logarithm with the same base. Assume all expressions exist and are well-defined. Simplify any fractions. 2log_(w)x+4log_(w)2x
The simplified expression is log_(w)(16x^6)
To rewrite the logarithmic expression as a single logarithm with the same base, we need to use the properties of logarithms. The properties we will use are:
1) log_b(x)+log_b(y) = log_b(xy)
2) a*log_b(x) = log_b(x^a)
Using the first property, we can combine the two terms with the same base:
2log_(w)x+4log_(w)2x = log_(w)x^2+log_(w)(2x)^4
Using the second property, we can simplify the exponents:
log_(w)x^2+log_(w)(2x)^4 = log_(w)x^2+log_(w)16x^4
Using the first property again, we can combine the two terms with the same base:
log_(w)x^2+log_(w)16x^4 = log_(w)(x^2*16x^4)
Simplifying the expression inside the logarithm:
log_(w)(x^2*16x^4) = log_(w)(16x^6)
Therefore, the final expression is:
2log_(w)x+4log_(w)2x = log_(w)(16x^6)
Answer: log_(w)(16x^6)

Given sin tetha= -12/13 and tetha is in the 4rd quadrant, find the following using Double Angle 13 identities. Show all work/formulas and give answers in exact form (no decimals). a. sin2tetha b. cos2tetha
Given sin θ = -12/13 and θ is in the 4th quadrant, we can use the double angle identities to find sin 2θ and cos 2θ. The double angle identities are:
sin 2θ = 2sin θcos θ
cos 2θ = cos^2 θ - sin^2 θ
First, we need to find cos θ. Since θ is in the 4th quadrant, we know that cos θ is positive. Using the Pythagorean identity, we can find cos θ:
sin^2 θ + cos^2 θ = 1
(-12/13)^2 + cos^2 θ = 1
144/169 + cos^2 θ = 1
cos^2 θ = 25/169
cos θ = 5/13
Now, we can use the double angle identities to find sin 2θ and cos 2θ:
sin 2θ = 2sin θcos θ = 2(-12/13)(5/13) = -120/169
cos 2θ = cos^2 θ - sin^2 θ = (5/13)^2 - (-12/13)^2 = -119/169
Therefore, the answers are:
a. sin 2θ = -120/169
b. cos 2θ = -119/169

Solve for x. If there is more than one solution, separate the solutions (1)/(x-6)+(x)/(x)=(-9x+3)/(2)
The value of x for this solution is x = -2, 3, -3.
To solve for x, we need to combine like terms and then isolate x on one side of the equation. Here are the steps:
1. Multiply both sides of the equation by the common denominator of (x)(x-6)(2) to eliminate the fractions:
(1)(x)(2) + (x)(x-6)(2) = (-9x+3)(x)(x-6)
2x + 2x^2 - 12x = -9x^3 + 3x^2 - 54x + 18
2. Combine like terms:
2x^2 - 10x = -9x^3 + 3x^2 - 54x + 18
3. Move all terms to one side of the equation:
9x^3 - x^2 + 44x - 18 = 0
4. Use the Rational Root Theorem to find possible solutions:
The possible rational roots are ±1, ±2, ±3, ±6, ±9, ±18
5. Use synthetic division to test the possible roots and find the actual solutions:
When we divide by -2, we get a remainder of 0, so -2 is a solution.
When we divide by 3, we get a remainder of 0, so 3 is a solution.
When we divide by -3, we get a remainder of 0, so -3 is a solution.
6. The solutions are x = -2, x = 3, and x = -3.
So the final answer is:
x = -2, 3, -3
