Part A: dx/dy at y=4 equals 1/3. The correct option is (c) 1/3.
Part B: The value of dx/dy at y=2 is 1/5. the answer is (c) 1/5.
C. f'(x) = (1/2) * sqrt(x)^-1.
Part A:
We know that y=f(x) and x=f^-1(y) are mutually inverse functions, which means that f(f^-1(y))=y and f^-1(f(x))=x. Using implicit differentiation, we can find the derivative of x with respect to y as follows:
d/dy [f^-1(y)] = d/dx [f^-1(y)] * d/dy [x]
1 = (1/ (dx/dy)) * d/dy [x]
(dx/dy) = d/dy [x]
Now, we are given that f(1)=4 and dy/dx = -3 at x=1. Using the chain rule, we can find the derivative of y with respect to x as follows:
dy/dx = (dy/dt) * (dt/dx)
-3 = (dy/dt) * (1/ (dx/dt))
(dx/dt) = -1/3
We want to find dx/dy at y=4. Since y=f(x), we can find x by solving for x in terms of y:
y = f(x)
4 = f(x)
x = f^-1(4)
Using the inverse function property, we know that f(f^-1(y))=y, so we can substitute x=f^-1(4) into f(x) to get:
f(f^-1(4)) = 4
f(x) = 4
Now, we can find dy/dx at x=4 using the given derivative dy/dx = -3 at x=1 and differentiating implicitly:
dy/dx = (dy/dt) * (dt/dx)
dy/dx = (-3) * (dx/dt)
We know that dx/dt = -1/3 from earlier, so:
dy/dx = (-3) * (-1/3) = 1
Finally, we can find dx/dy at y=4 using the formula we derived earlier:
(dx/dy) = d/dy [x]
(dx/dy) = 1/ (d/dx [f^-1(y)])
We can find d/dx [f^-1(y)] using the fact that f(f^-1(y))=y:
f(f^-1(y)) = y
f(x) = y
x = f^-1(y)
So, d/dx [f^-1(y)] = 1/ (dy/dx). Plugging in dy/dx = 1 and y=4, we get:
(dx/dy) = 1/1 = 1
Therefore, the answer is (c) 1/3.
Part B:
Let y=f(x) and x=h(y) be mutually inverse functions. We know that f '(2)=5, which means that the derivative of f(x) with respect to x evaluated at x=2 is 5. Using the chain rule, we can find the derivative of x with respect to y as follows:
dx/dy = (dx/dt) * (dt/dy)
We know that x=h(y), so:
dx/dy = (dx/dt) * (dt/dy) = h'(y)
To find h'(2), we can use the fact that y=f(x) and x=h(y) are mutually inverse functions, so:
y = f(h(y))
2 = f(h(2))
Differentiating implicitly with respect to y, we get:
dy/dx * dx/dy = f'(h(2)) * h'(2)
dx/dy = h'(2) = (dy/dx) / f'(h(2))
We know that f'(h(2))=5 from the given information, and we can find dy/dx at x=h(2) using the fact that y=f(x) and x=h(y) are mutually inverse functions, so:
y = f(x)
2 = f(h(y))
2 = f(h(x))
dy/dx = 1 / (dx/dy)
Plugging in f'(h(2))=5, dy/dx=1/(dx/dy), and y=2, we get:
dx/dy = h'(2) = (dy/dx) / f'(h(2)) = (1/(dx/dy)) / 5 = (1/5)
Therefore, the answer is (c) 1/5.
Part C:
We are given that f(x)= for x>0. Differentiating with respect to x using the power rule, we get:
f'(x) = (1/2) * x^(-1/2)
Therefore, f'(x) = (1/2) * sqrt(x)^-1.

I don’t know how to do this (geometry)
Answer: The value of x = 7
Step-by-step explanation:
In the figure consider the parallelogram is a ABCD parallelogram
A parallelogram is a two-dimensional shape.
It has four sides, in which two pairs of sides are parallel.
Also, the parallel sides are equal in length.
If the length of the parallel sides is not equal in measurement, then the shape is not a parallelogram.
Similarly, the opposite interior angles of a parallelogram should always be equal. Otherwise, it is not a parallelogram.
AB = 3x+5
CD = 5x-9
where AB || CD and AD || BC
Also, AB = CD and AD = BC
then 3x+5 = 5x-9
when simplify the equation,
5x = 3x+5+9
5x = 3x+14
then
5x-3x = 14
2x = 14
x = 14÷2
x = 7
then the value of x = 7
when substituting value of x in equations
AB = 3x+5 = 21+5 = 26
CD = 5x-9 = 35-9 = 26
AB = CD

If index of refraction 1 is 1. 5, index of refraction 2 is 2. 0, and the angle of incidence is 45 degrees, what is the angle of refraction?.
The angle of refraction is 32 degrees. The result is obtained by using the formula from the Snell's Law.
What is Snell's Law?The Snell's Law is a formula to describe the relationship between the angles of incidence and refraction when a light passes through two medias. It can be expressed as
n₁ / n₂ = sin θ₂ / sin θ₁
Where
n₁ = refractive index of medium 1n₂ = refractive index of medium 2 θ₁ = incident angleθ₂ = refracted angleWe have:
Index of refraction 1, n₁ = 1.5.Index of refraction 2, n₂ = 2.0.Angle of incident, θ₁ = 45°.Find the angle of refraction!
Using the formula of Snell's Law, we'll get the refracted angle.
n₁ / n₂ = sin θ₂ / sin θ₁
1.5 / 2.0 = sin θ₂ / sin 45°
3 / 4 = sin θ₂ / (½√2)
sin θ₂ = 3(½√2)/4
sin θ₂ = 3/8 √2
sin θ₂ = 0.53
θ₂ = arc sin 0.53
θ₂ = 32°

What is horizontal line test inverse?
The horizontal line test is a method used to determine if a given function is one-to-one, which means that for every unique x-value, there is a unique y-value. A function that is one-to-one can be inverted, meaning that it has an inverse function.
The inverse function of a one-to-one function is a function that undoes the original function.
The horizontal line test is used to determine if a given function is one-to-one by drawing a horizontal line through the graph of the function and seeing if the line intersects the graph at most once.
If the function is one-to-one, it has an inverse function and it can be found by switching the x and y values and solving for y.
For example, if the original function is f(x) = 2x + 1, its inverse function is f^-1(x) = (x-1)/2. This inverse function undoes the original function and it can be used to solve equations, find derivatives, and study geometric transformations.
It's important to note that the horizontal line test is only a sufficient condition, meaning that a function that passes the horizontal line test is one-to-one, but not all one-to-one function pass the horizontal line test.
In conclusion, the horizontal line test is a method used to determine if a given function is one-to-one, which is important because one-to-one functions can be inverted.
The inverse function undoes the original function, and it can be found by switching the x and y values and solving for y. The test is simple and easy to apply, but only a sufficient condition.

find the maximum value of y= -8x^2 + 80x -196
Answer:
(5,4)
Step-by-step explanation:
first, if you have a calculator you can put the equation into y = and just find the maximum point there
to find the x value of the maximum point you do -B/2A
-80/2(8) = 5 so the x value would be 5
then to find y just plug in 5 for x and you should get 4
Answer:
Maximum value of
[tex]f(x) = - 8x^2 + 80x - 196[/tex]
is
[tex]\boxed{f(x) = 4}[/tex]
Step-by-step explanation:
The maximum or minimum value of a function f(x) occurs when the first derivative equals zero
The first derivative of
[tex]f(x) = - 8x^2 + 80x - 196[/tex]
[tex]f'(x) = \dfrac{d}{dx}\left(-8x^2+80x-196\right)[/tex]
[tex]=-\dfrac{d}{dx}\left(8x^2\right)+\dfrac{d}{dx}\left(80x\right)-\dfrac{d}{dx}\left(196\right)[/tex]
[tex]\dfrac{d}{dx}\left(8x^2\right) = 16x\\\\=- \dfrac{d}{dx}\left(8x^2\right) = -16x\\\\\\\dfrac{d}{dx}\left(80x\right)=80\\\\\dfrac{d}{dx}\left(196\right)=0[/tex]
[tex]\dfrac{d}{dx}\left(-8x^2+80x-196\right) \\\\\\ =-16x + 80 + 0\\\\= -16x + 80\\\\[/tex]
Set this expression equal to 0 and solve for x to find the x value which maximizes or minimizes the function
[tex]-16x + 80 = 0\\\\\implies -16x = -80\\\\x = -80/-16\\\\x = 5\\\\[/tex]
Plug this value of x into the original function to get the maximum or minimum value.
[tex]f(5) = -8(5^2) + 80(5) - 196\\\\= -8 (25) +400 -196\\\\= -200 + 400 - 196\\\\= 4\\\\[/tex]
So the maximum value of [tex]\boxed{f(x) = 4}[/tex] ANS
and occurs at [tex]x = 5[/tex]
(Strictly speaking to find if this is a maximum or minimum, we have to find the second derivative and see if it is negative or positive. If negative, it is a maximum, if positive it is a minimum
But since the question does not ask for this, I am skipping it. In case you are interested, the second derivative of f(x) is the derivative of f'(x) which will work out to -16 so it is a maximum)
Choose the function that represents the data in the table. Y = 3x + 2 y = 3x2 + 2 y = y = 3x + 2.
The function that represents the data in the table is 3x²+2. The correct answer is B.
The quadratic function is shown in the data table.
We must ascertain the function's equation.
The quadratic equation's generic form is
Let's replace the general form with the three coordinates (1,5, (2,14), and (3,29).
We therefore have;
a+b+c =5——— (1)
4a+2b+c= 14——— (2)
9a+3b+C =29------(3)
When (2) is subtracted from (1), we have;
9= 3a+b(4)
Subtracting (3) from (2) gives us;
15= 5a +b(5)
Subtracting (5) from (4) gives us;
6= 2a
3= a
As a result, the value of an is 3. When we replace this value in equation (4), we obtain;
3(3)+b= 9
b= 0
When a = 3 and b = 0 are substituted in equation (1), we obtain;
a+b+c =5
3+0+c=5
c=2
As a result, c has a value of 2.
As a result, when we substitute a = 3, b = 0, and c = 2 in the quadratic equation's general form y =ax²+bx+c, we obtain;
3x²+2
Consequently, the function that symbolizes the information in the table is 3x²+2

R's positive value is [tex]\sqrt{\frac{v}{\pi h} }[/tex] V =r²h in terms of h is the formula used to calculate the volume of a cylinder.
what is volume ?The object's capacity is another name for it. The basic formula for volume is length, width, and height, as opposed to the basic formula for the area of a rectangular shape, which is length, breadth, and height. No matter how you refer to the various dimensions, the calculation remains the same. For instance, you can use "depth" instead of "height." The capacity of an object is expressed in terms of volume. A cup's capacity is said to be 100 ml, for instance, if it can hold 100 ml of water in its brim. The quantity of space a three-dimensional item takes up can also be referred to as volume.
given
Cylinder(volume )'s is equal to = [tex]\pi r^{2}h[/tex]
where r = radius, h = height, and v = volume of the cylinder
⇒ [tex]r^{2} = \frac{v}{\pi h}[/tex]
⇒ ±r = [tex]\sqrt{\frac{v}{\pi h} }[/tex]
The problem states that only the positive value of r is necessary.
So, r = [tex]\sqrt{\frac{v}{\pi h} }[/tex]
R's positive value is [tex]\sqrt{\frac{v}{\pi h} }[/tex] V =r²h in terms of h is the formula used to calculate the volume of a cylinder.

I am trying to find the second, fourth, and eleventh terms of the sequence for A(n)=-9+(n-1)(3)
By evaluating the formula for the sequence, we will get the terms:
A(2) = -6A(4) = 0A(11) = 21How to find the terms in the sequence?Here we want to find the second, fourth, and eleventh terms in the sequence:
A(n) = -9 + (n - 1)*3
n defines the "number" of the term in the sequence.
So to get the second term, we need to use n = 2, we will get.
A(2) = -9 + (2 - 1)*3
A(2) = -9 + 3 = -6
The fourth term is what we get if we evaluate in n = 4, then:
A(4) = -9 + (4 - 1)*3
A(4) = -9 + 9 = 0
And the eleventh term is what we get when we use n = 11, we will get:
A(11) = -9 + (11 - 1)*3
A(11) = -9 + 30 = 21
These are the 3 terms of the sequence that we wanted to find.

Which of the following is the correct solution for the equation 5t 3 3t 5?A. -1B. -2C. 1D. 2
The solution for the equation 5t - 3 = 3t - 5 is when value of t is equal to -1.
Therefore the answer is A. -1.
To find the solution, you can start by isolating the variable t on one side of the equation by adding 3 to both sides and subtracting 3t from both sides:
5t - 3 + 3 = 3t - 5 + 3
5t = 3t - 2
Then subtract 3t from both sides:
5t - 3t = 3t -2 - 3t
2t = -2
Finally, divide both sides by 2 to solve for t:
t = -2/2
t = -1
So, the value of t that satisfies the equation 5t - 3 = 3t - 5 is -1.
