a) The position function is x(t) = t^2 + 2, y(t) = t^2 - t + 1, z(t) = 2t - 2t^2
b) Tthe cosine of the angle between the velocity and acceleration vectors at the point (6, 3, -4) is: cosθ = (v(6) · a(6)) / (|v(6)| |a(6)|) = 134 / (sqrt(749) * sqrt(24))
c) The particle reaches its minimum speed at t = 1/12.
(a) To find the particle's position at any time t, we need to integrate the velocity function with respect to time. The position function can be obtained by integrating each component of the velocity vector.
Given velocity function: v(t) = (2t, 2t - 1, 2 - 4t)
Integrating the x-component:
x(t) = ∫(2t) dt = t^2 + C1
Integrating the y-component:
y(t) = ∫(2t - 1) dt = t^2 - t + C2
Integrating the z-component:
z(t) = ∫(2 - 4t) dt = 2t - 2t^2 + C3
where C1, C2, and C3 are constants of integration.
Now, to determine the specific values of the constants, we can use the initial position given as (2, 1, 0) when t = 0.
x(0) = 0^2 + C1 = 2 --> C1 = 2
y(0) = 0^2 - 0 + C2 = 1 --> C2 = 1
z(0) = 2(0) - 2(0)^2 + C3 = 0 --> C3 = 0
Therefore, the position function is:
x(t) = t^2 + 2
y(t) = t^2 - t + 1
z(t) = 2t - 2t^2
(b) To find the cosine of the angle between the velocity and acceleration vectors, we need to find both vectors at the given point (6, 3, -4) and then calculate their dot product.
Given velocity function: v(t) = (2t, 2t - 1, 2 - 4t)
Given acceleration function: a(t) = (d/dt) v(t) = (2, 2, -4)
At the point (6, 3, -4), let's find the velocity and acceleration vectors.
Velocity vector at t = 6:
v(6) = (2(6), 2(6) - 1, 2 - 4(6)) = (12, 11, -22)
Acceleration vector at t = 6:
a(6) = (2, 2, -4)
Now, let's calculate the dot product of the velocity and acceleration vectors:
v(6) · a(6) = (12)(2) + (11)(2) + (-22)(-4) = 24 + 22 + 88 = 134
The magnitude of the velocity vector at t = 6 is:
|v(6)| = sqrt((12)^2 + (11)^2 + (-22)^2) = sqrt(144 + 121 + 484) = sqrt(749)
The magnitude of the acceleration vector at t = 6 is:
|a(6)| = sqrt((2)^2 + (2)^2 + (-4)^2) = sqrt(4 + 4 + 16) = sqrt(24)
Therefore, the cosine of the angle between the velocity and acceleration vectors at the point (6, 3, -4) is:
cosθ = (v(6) · a(6)) / (|v(6)| |a(6)|) = 134 / (sqrt(749) * sqrt(24))
(c) To find the time(s) when the particle reaches its minimum speed, we need to determine when the magnitude of the velocity vector is at its minimum.
Given velocity function: v(t) = (2t, 2t - 1, 2 - 4t)
The magnitude of the velocity vector is:
|v(t)| = sqrt((2t)^2 + (2t - 1)^2 + (2 - 4t)^2) = sqrt(4t^2 + 4t^2 - 4t + 1 + 4 - 16t + 16t^2)
= sqrt(24t^2 - 4t + 5)
To find the minimum speed, we can take the derivative of |v(t)| with respect to t and set it equal to 0, then solve for t.
d|v(t)| / dt = 0
(1/2) * (24t^2 - 4t + 5)^(-1/2) * (48t - 4) = 0
Simplifying:
48t - 4 = 0
48t = 4
t = 1/12
Therefore, the particle reaches its minimum speed at t = 1/12.

The equation of the line that is perpendicular to the line x+4y = -4 and passes through the origin (0,0) is 4x - y = 0.
To find the equation of a line perpendicular to another line, we need to determine the negative reciprocal of the slope of the given line.
The given line, x+4y = -4, can be rewritten in slope-intercept form as y = (-1/4)x - 1. The slope of this line is -1/4.
The negative reciprocal of -1/4 is 4/1, which is the slope of the perpendicular line.
Using the point-slope form of a line, we have y - y₁ = m(x - x₁), where (x₁, y₁) represents a point on the line. Since the perpendicular line passes through the origin (0,0), we can substitute x₁ = 0 and y₁ = 0 into the equation.
Therefore, the equation of the line perpendicular to x+4y = -4 and passing through the origin is y - 0 = (4/1)(x - 0), which simplifies to 4x - y = 0.

A triangle has sides with lengths of 11 feet, 9 feet,
and 14 feet. Is it a right triangle?
Step-by-step explanation:
Not a right triangle.
To determine if a triangle is a right triangle, we can apply the Pythagorean theorem. According to the theorem, in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's calculate:
The given side lengths are:
Side A: 11 feet
Side B: 9 feet
Side C: 14 feet (hypotenuse)
According to the Pythagorean theorem, if the triangle is a right triangle, then:
Side A^2 + Side B^2 = Side C^2
Substituting the values:
11^2 + 9^2 = 14^2
121 + 81 = 196
202 ≠ 196
Since 202 is not equal to 196, we can conclude that the triangle with side lengths 11 feet, 9 feet, and 14 feet is not a right triangle.

The complement of K3,4 has 21 - 12 = 9 edges. Complement of a graph is the graph with the same vertices, but whose edges are the edges not in the original graph.
A graph G and its complement G' have the same number of vertices. If the graph G has vertices u and v but does not have an edge between u and v, then the graph G' has an edge between u and v, and vice versa. Therefore, if uv is an edge in G, then uv is not an edge in G'.Similarly, if uv is not an edge in G, then uv is an edge in G'.
The given graph is K3,4, which means it has three vertices on one side and four vertices on the other. A complete bipartite graph has an edge between every pair of vertices with different parts;
therefore, the number of edges in K3,4 is 3 x 4 = 12.
To obtain the complement of K3,4, the edges in K3,4 need to be removed.
Since there are 12 edges in K3,4, there are 12 edges not in K3,4.
Since each edge in the complement of K3,4 corresponds to an edge not in K3,4, the complement of K3,4 has 12 edges.

The gradient at the point (1, 2) on the curve is -1. The equation of the tangent line to the curve at the point (1, 2) is y = -x + 3.
To find the gradient at a specific point on the curve, we need to differentiate the equation with respect to y and substitute the coordinates of the point into the derivative.
The given equation is: I + ry + y^2 = 12 – 2^2 - y^2
Differentiating both sides with respect to y, we get:
r + 2y = 0
Substituting the x-coordinate of the point (1, 2), we have:
r + 2(2) = 0
r + 4 = 0
r = -4
Therefore, the gradient at the point (1, 2) on the curve is -1.
(ii) To find the equation of the tangent line to the curve at the point (1, 2), we can use the point-slope form of a line. The equation of a line with gradient m passing through the point (x₁, y₁) is given by y - y₁ = m(x - x₁).
Using the point (1, 2) and the gradient -1 we found earlier, we can substitute these values into the equation to find the tangent line:
y - 2 = -1(x - 1)
y - 2 = -x + 1

To evaluate the surface integral of the given vector field over the solid bounded by the paraboloid and the xy plane, we can use the surface integral formula. First, we need to determine the boundary surface of the solid. In this case, the boundary surface is the paraboloid z = 1 - x² - y².
To set up the surface integral, we need to find the outward unit normal vector to the surface. The unit normal vector is given by n = ∇f/|∇f|, where f is the equation of the surface. In this case, f(x, y, z) = z - (1 - x² - y²). Taking the gradient of f, we get ∇f = -2xi - 2yj + k.

The flux of F across S is 0.
The surface integral ∫∫S F · dS is used to find the flux of the vector field F across the oriented surface S. In this case, the vector field F is given by F(x, y, z) = xy i + 4x2 j + yz k and the oriented surface S is given by z = xey, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, with upward orientation.
To evaluate the surface integral, we need to find the normal vector to the surface S. The normal vector is given by the cross product of the partial derivatives of the surface equation with respect to x and y:
∂S/∂x = <1, 0, ey>
∂S/∂y = <0, 1, xey>
N = ∂S/∂x x ∂S/∂y = <-ey, -xey, 1>
Since the surface S has an upward orientation, we need to make sure that the normal vector N points upward. We can do this by taking the dot product of N with the upward vector k:
N · k = -ey * 0 - xey * 0 + 1 * 1 = 1
Since the dot product is positive, the normal vector N points upward and we can use it in the surface integral.
Next, we need to substitute the surface equation z = xey into the vector field F to get F(x, y, xey) = xy i + 4x2 j + xyey k.
Now we can evaluate the surface integral:
∫∫S F · dS = ∫∫S (xy i + 4x2 j + xyey k) · (-ey i - xey j + k) dS

Both the analytical and graphical analysis demonstrate that f and g are inverse functions.
To show that two functions, f and g, are inverse functions analytically, we need to demonstrate that the composition of the functions yields the identity function.
First, let's find the composition of f and g:
[tex]f(g(x)) = f(√(√(25 - x)))[/tex]
[tex]= 25 - (√(√(25 - x)))²= 25 - (√(25 - x))²[/tex]
= 25 - (25 - x)
= x
Similarly, let's find the composition of g and f:
[tex]g(f(x)) = g(25 - x²)[/tex]
= [tex]g(f(x)) = g(25 - x²)[/tex]
[tex]= √(√(x²))= √x[/tex]
= g
Since f(g(x)) = x and g(f(x)) = x, we have shown analytically that f and g are inverse functions.
To illustrate this graphically, we can plot the functions f(x) = 25 - x² and g(x) = √(√(25 - x)) on the same graph.
The graph of f(x) = 25 - x² is a downward-opening parabola centered at (0, 25) with its vertex at the maximum point. It represents a curve.
The graph of g(x) = √(√(25 - x)) is the square root function applied twice. It represents a curve that starts from the point (25, 0) and gradually increases as x approaches negative infinity. The function is undefined for x > 25.
By observing the graph, we can see that the graph of g is the reflection of the graph of f across the line y = x. This symmetry confirms that f and g are inverse functions.
Therefore, both the analytical and graphical analysis demonstrate that f and g are inverse functions.

Z is the z-score corresponding to the desired confidence level (in this case, for a 99% confidence level, Z is the z-score that leaves a 0.5% tail on each side, which is approximately 2.576).
σ is the population standard deviation.
n is the sample size.
Plugging in the given values, we have:

= [3(n+1) / (2n+1)] ⋅ [(2n-1) / 1]
Simplifying further:
|A_(n+1) / A_n| = [3(n+1)(2n-1)] / [(2n+1)]
Now, we take the limit of this expression as n approaches infinity:
lim (n → ∞) |A_(n+1) / A_n| = lim (n → ∞) [3(n+1)(2n-1)] / [(2n+1)]
To evaluate this limit, we can divide both the numerator and denominator by n:
lim (n → ∞) |A_(n+1) / A_n| = lim (n → ∞) [3(1 + 1/n)(2 - 1/n)] / [(2 + 1/n)]
Taking the limit as n approaches infinity, we have:
lim (n → ∞) |A_(n+1) / A_n| = 3(1)(2) / 2 = 3

To find the radius of convergence of the series A_n = (1 ⋅ 3 ⋅ 6 ⋅ ... ⋅ (3n)) / (1 ⋅ 3 ⋅ 5 ⋅ ... ⋅ (2n-1)), we can use the ratio test.
The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is L as n approaches infinity, then the series converges if L < 1 and diverges if L > 1. If L = 1, the test is inconclusive.
Let's apply the ratio test to the given series:
|A_(n+1) / A_n| = [(1 ⋅ 3 ⋅ 6 ⋅ ... ⋅ (3(n+1))) / (1 ⋅ 3 ⋅ 5 ⋅ ... ⋅ (2(n+1)-1))] / [(1 ⋅ 3 ⋅ 6 ⋅ ... ⋅ (3n)) / (1 ⋅ 3 ⋅ 5 ⋅ ... ⋅ (2n-1))]
= [(3(n+1)) / ((2(n+1)-1))] / [(1) / (2n-1)]

The formula for the nth term of the given sequence is an = (n^(n-1)) * (n/2)^n.
To find a formula for the nth term of the given sequence, we can observe the pattern of the terms.
The given sequence is: 1, 11, 1', 8', 27', ...
From the pattern, we can notice that each term is obtained by raising a number to the power of n, where n is the position of the term in the sequence.
Let's analyze each term:
1st term: 1 = 1^1
2nd term: 11 = 1^2 * 11
3rd term: 1' = 1^3 * 1'
4th term: 8' = 2^4 * 1'
5th term: 27' = 3^5 * 1'
We can see that the nth term can be obtained by raising n to the power of n and multiplying it by a constant, which is 1 for odd terms and the value of n/2 for even terms.
Based on this pattern, we can write the formula for the nth term (an) as follows: an = (n^(n-1)) * (n/2)^n, where n is the position of the term in the sequence.
Therefore, the formula for the nth term of the given sequence is an = (n^(n-1)) * (n/2)^n.

A: contains zero vector B:closed inder vector addition C: closed under multiplication by scalars A) His not a vector space; does not contain zero vector B) His not a vector space; not closed under multiplication by scalars and does not contain zero vector C) H is not a vector space; not closed under vector addition D) H is not a vector space; not closed under multiplication by scalars.
The set H of polynomials of the form P(t) = a + bt², where a and b are real numbers with b > a, is not a vector space. It fails to satisfy property C: it is not closed under vector addition.
In order for a set to be a vector space, it must satisfy several properties: containing a zero vector, being closed under vector addition, and being closed under multiplication by scalars. Let's examine each property for the set H:
A) Contains zero vector: The zero vector in this case would be the polynomial P(t) = 0 + 0t² = 0. However, this polynomial does not have the form a + bt² with b > a, as required by H. Therefore, H does not contain a zero vector.
B) Closed under vector addition: To check this property, we take two arbitrary polynomials P(t) = a + bt² and Q(t) = c + dt² from H and try to add them. The sum of these polynomials is (a + c) + (b + d)t². However, it is possible to choose values of a, b, c, and d such that (b + d) is less than (a + c), violating the condition b > a. Hence, H is not closed under vector addition.
C) Closed under multiplication by scalars: Multiplying a polynomial P(t) = a + bt² from H by a scalar k results in (ka) + (kb)t². Since a and b can be any real numbers, there are no restrictions on their values that would prevent the resulting polynomial from being in H. Therefore, H is closed under multiplication by scalars.
In conclusion, the set H fails to satisfy property C: it is not closed under vector addition. Therefore, H is not a vector space.

To isolate the trigonometric function in the equation 1 + 2cos(x + 5) = 0, we need to solve the equation for cos(x). By rearranging the equation and using trigonometric identities, we can find the value of cos(x) and determine the solutions.
To isolate the trigonometric function cos(x) in the equation 1 + 2cos(x + 5) = 0, we begin by subtracting 1 from both sides of the equation, yielding 2cos(x + 5) = -1. Next, we divide both sides by 2, resulting in cos(x + 5) = -1/2.
Now, we know that the cosine function has a value of -1/2 at an angle of 120 degrees (or 2π/3 radians) and 240 degrees (or 4π/3 radians) in the unit circle. However, the given equation has an argument of (x + 5) instead of x. To find the solutions for cos(x), we need to solve the equation (x + 5) = 2π/3 + 2πn or (x + 5) = 4π/3 + 2πn, where n is an integer representing the number of full cycles.
By subtracting 5 from both sides of each equation, we obtain x = 2π/3 - 5 + 2πn or x = 4π/3 - 5 + 2πn as the solutions for cos(x) = -1/2. These equations represent all the values of x where cos(x) equals -1/2, accounting for the periodic nature of the cosine function.

Let f(x, y) = x^3 + y^2 + 2xy. Find the directional derivative of f in the direction v = (3,-4) at the point (1,2) b. Find a vector in the direction of maximum increase of the function f(x,y) above at the point (1,2).
a) The directional derivative of function is -3/5.
b) The direction of maximum increase of the function f(x, y) is (7/√85, 6/√85).
How to find the directional derivative of a function f(x, y) in the direction of vector v = (3, -4) at the point (1, 2)?To find the directional derivative of a function f(x, y) in the direction of vector v = (3, -4) at the point (1, 2), we need to compute the dot product between the gradient of f and the unit vector in the direction of v.
Let's start by finding the gradient of f(x, y):
∇f = (∂f/∂x, ∂f/∂y)
Taking partial derivatives of f(x, y) with respect to x and y, we have:
∂f/∂x = [tex]3x^2 + 2y[/tex]
∂f/∂y = 2y + 2x
Evaluating these partial derivatives at the point (1, 2):
∂f/∂x = [tex]3(1)^2 + 2(2) = 7[/tex]
∂f/∂y = 2(2) + 2(1) = 6
Now, we need to compute the unit vector in the direction of v = (3, -4):
||v|| = √[tex](3^2 + (-4)^2)[/tex] = √(9 + 16) = √25 = 5
The unit vector u in the direction of v is given by:
u = (3/5, -4/5)
Finally, the directional derivative of f in the direction of v at the point (1, 2) is given by the dot product of the gradient and the unit vector:
D_vf(1, 2) = ∇f(1, 2) · u = (∂f/∂x, ∂f/∂y) · (3/5, -4/5) = (7, 6) · (3/5, -4/5)
Calculating the dot product:
D_vf(1, 2) = 7(3/5) + 6(-4/5) = 21/5 - 24/5 = -3/5
Therefore, the directional derivative of f in the direction of v = (3, -4) at the point (1, 2) is -3/5.
How to find a vector in the direction of maximum increase of the function f(x, y) at the point (1, 2)?To find a vector in the direction of maximum increase of the function f(x, y) at the point (1, 2), we can use the gradient vector ∇f(1, 2).
Since the gradient vector points in the direction of maximum increase, we can normalize it to obtain a unit vector.
The gradient vector ∇f(1, 2) = (7, 6).
To normalize this vector, we divide it by its magnitude:
||∇f(1, 2)|| = √[tex](7^2 + 6^2)[/tex]= √(49 + 36) = √85
The unit vector in the direction of maximum increase is then:
v_max = (∇f(1, 2)) / ||∇f(1, 2)|| = (7/√85, 6/√85)
Therefore, a vector in the direction of maximum increase of the function f(x, y) at the point (1, 2) is (7/√85, 6/√85).

challenge activity 1.20.2: tree height. given variables angle elev and shadow len that represent the angle of elevation and the shadow length of a tree, respectively, assign tree height with the height of the tree. ex: if the input is: 3.8 17.5
Therefore, if the input is angle_elev = 3.8 and shadow_len = 17.5, the estimated height of the tree would be approximately 1.166 meters.
To calculate the height of a tree given the angle of elevation (angle_elev) and the shadow length (shadow_len), you can use trigonometry.
Let's assume that the tree height is represented by the variable "tree_height". Here's how you can calculate it:
Convert the angle of elevation from degrees to radians. Most trigonometric functions expect angles to be in radians.
angle_elev_radians = angle_elev * (pi/180)
Use the tangent function to calculate the tree height.
tree_height = shadow_len * tan(angle_elev_radians)
Now, if the input is angle_elev = 3.8 and shadow_len = 17.5, we can plug these values into the formula:
angle_elev_radians = 3.8 * (pi/180)
tree_height = 17.5 * tan(angle_elev_radians)
Evaluating this expression:
angle_elev_radians ≈ 0.066322511

The kernel of the linear transformation t: P₃ → P₂ defined by t(p) = p' is the set of polynomials in P₃ that map to the zero polynomial in P₂z The kernel of t, denoted ker(t), consists of the polynomials p(x) = a₀ + a₁x + a₂x² + a₃x³ where a₀, a₁, a₂, and a₃ are arbitrary constant coefficients in ℝ.

Let's consider a polynomial p(x) = a₀ + a₁x + a₂x² + a₃x³. Taking the derivative of p with respect to x, we obtain p'(x) = a₁ + 2a₂x + 3a₃x².
For p' to be the zero polynomial, all the coefficients of p' must be zero. Therefore, we have the following conditions:
a₁ = 0
2a₂ = 0
3a₃ = 0

Suppose the region E is given by {(x, y, z) | √√x² + y² ≤ z ≤ √√4 - x² - y²) Evaluate J²² x² dV (Hint: this is probably best done using spherical coordinates)
To evaluate the integral J²² x² dV over the region E, we can utilize spherical coordinates. The final solution involves integrating a specific expression over the given region and can be obtained by following the detailed steps below.
To evaluate the integral J²² x² dV over the region E, we can express the region E in terms of spherical coordinates. In spherical coordinates, we have:
x = ρsin(φ)cos(θ)
y = ρsin(φ)sin(θ)
z = ρcos(φ)
where ρ represents the radial distance, φ is the polar angle, and θ is the azimuthal angle.
Next, we need to determine the bounds for the variables ρ, φ, and θ that correspond to the region E.
From the given condition, we have:
√√x² + y² ≤ z ≤ √√4 - x² - y²
Simplifying this expression, we get:
√(√(ρ²sin²(φ)cos²(θ)) + ρ²sin²(φ)sin²(θ)) ≤ ρcos(φ) ≤ √√4 - ρ²sin²(φ)cos²(θ) - ρ²sin²(φ)sin²(θ))
Squaring both sides and simplifying, we obtain:
ρ²sin²(φ)(1 - sin²(φ)) ≤ ρ²cos²(φ) ≤ √√4 - ρ²sin²(φ))
Further simplifying, we have:
ρ²sin²(φ)cos²(φ) ≤ ρ²cos²(φ) ≤ √√4 - ρ²sin²(φ))
Now, we can find the bounds for ρ, φ, and θ that satisfy these inequalities.
For ρ, since it represents the radial distance, the bounds are determined by the limits of the region E. We have 0 ≤ ρ ≤ √√4 = 2.
For φ, the polar angle, we need to find the bounds that satisfy the inequalities. Solving ρ²sin²(φ)cos²(φ) ≤ ρ²cos²(φ) and √√4 - ρ²sin²(φ)) ≤ ρ²cos²(φ)), we get 0 ≤ φ ≤ π/2.
For θ, the azimuthal angle, we can take the full range of 0 ≤ θ ≤ 2π.
Now, we can express the integral J²² x² dV in terms of spherical coordinates as follows:
J²² x² dV = ∫∫∫ ρ⁵sin³(φ)cos²(θ) dρ dφ dθ
To evaluate this integral, we perform the triple integral over the given bounds: 0 ≤ ρ ≤ 2, 0 ≤ φ ≤ π/2, and 0 ≤ θ ≤ 2π.
Calculating this triple integral will yield the final solution for the given integral over the region E.

Step-by-step explanation:
To determine if the series Σ((-1)^n)/(2^(5+n)) converges or diverges, we can use the alternating series test.
The alternating series test states that if a series has the form Σ((-1)^n)*b_n or Σ((-1)^(n+1))*b_n, where b_n is a positive sequence that decreases monotonically to 0, then the series converges.
In the given series, we have Σ((-1)^n)/(2^(5+n)). Let's analyze the terms:

The simplified difference quotient is 1.
To evaluate the difference quotient for the given functions, we need to substitute the given values into the formula and simplify the expression.
27) Difference quotient for f(x) = 9 + 3x - x²:
The difference quotient is given by:
[f(a + h) - f(a)] / h
Substituting the function f(x) = 9 + 3x - x² into the formula, we have:
[f(a + h) - f(a)] / h = [(9 + 3(a + h) - (a + h)²) - (9 + 3a - a²)] / h
Simplifying the expression, we get:
[f(a + h) - f(a)] / h = [9 + 3a + 3h - (a² + 2ah + h²) - 9 - 3a + a²] / h
= [3h - 2ah - h²] / h

[f(a + h) - f(a)] / h = 3 - 2a - h
Therefore, the simplified difference quotient is 3 - 2a - h.
29) Difference quotient for f(x) = √(x + 4):
The difference quotient is given by:
[f(x + h) - f(x)] / h
Substituting the function f(x) = √(x + 4) into the formula, we have:
[f(x + h) - f(x)] / h = [√(x + h + 4) - √(x + 4)] / h
To simplify this expression further, we need to rationalize the numerator. Multiply the numerator and denominator by the conjugate of the numerator:
[f(x + h) - f(x)] / h = [√(x + h + 4) - √(x + 4)] / h * (√(x + h + 4) + √(x + 4)) / (√(x + h + 4) + √(x + 4))
Simplifying the numerator using the difference of squares, we get:
[f(x + h) - f(x)] / h = [x + h + 4 - (x + 4)] / h * (√(x + h + 4) + √(x + 4)) / (√(x + h + 4) + √(x + 4))
= h / h * (√(x + h + 4) + √(x + 4)) / (√(x + h + 4) + √(x + 4))
= (√(x + h + 4) + √(x + 4)) / (√(x + h + 4) + √(x + 4))
The h terms cancel out, leaving us with:
[f(x + h) - f(x)] / h = 1
Therefore, the simplified difference quotient is 1.
