We can use the concept of similar triangles. Since the building and the statue are casting shadows simultaneously, the angle of elevation of the sun is the same for both. Therefore, the triangles formed by the building, its shadow, and the ground and the statue, its shadow, and the ground are similar triangles.

Let's use the given information:
- Building height = 51 feet
- Building shadow length = 48 feet
- Statue shadow length = 16 feet
- Statue height = x (this is what we need to find)

Now, set up a proportion using the ratios of the corresponding sides of the similar triangles:

(Building height / Building shadow length) = (Statue height / Statue shadow length)

(51 / 48) = (x / 16)

To find the statue height (x), cross-multiply and solve for x:

51 * 16 = 48 * x

816 = 48x

Now, divide by 48 to find the value of x:

x = 816 / 48
x = 17

So, the statue is 17 feet tall.

Step-by-step explanation:

The center of a circle is the midpoint of its diameter. The midpoint of the segment whose endpoints are (-2,5) and (4,7) is:

((-2 + 4)/2, (5 + 7)/2) = (1, 6)

Therefore, the center of the circle is (1, 6), and its radius is half the length of the diameter:

r = sqrt((4 - (-2))^2 + (7 - 5)^2)/2 = sqrt(40)/2 = sqrt(10)

The equation of a circle with center (h, k) and radius r is:

(x - h)^2 + (y - k)^2 = r^2

Substituting the values of (h, k, r) into the equation, we get:

(x - 1)^2 + (y - 6)^2 = 10

Therefore, the equation of the circle with the segment whose endpoints are (-2,5) and (4,7) as the diameter is:

The Master Theorem is a powerful tool for solving divide-and-conquer recurrences. It provides a way to quickly determine the asymptotic behavior of algorithms by analyzing their running time.

Case 1 of the Master Theorem applies to algorithms that split the problem into smaller subproblems of equal size and combine their solutions in constant time. In this case, the running time can be expressed as T(n) = aT(n/b) + f(n), where a is the number of subproblems, b is the size of each subproblem, and f(n) is the time to combine the subproblem solutions. The solution to this recurrence is T(n) = Θ(nlogba) if f(n) = Θ(nlogka) for some constant k < log(ba).

Case 2 of the Master Theorem applies to algorithms that split the problem into smaller subproblems of equal size and combine their solutions in linear time. In this case, the running time can be expressed as T(n) = aT(n/b) + f(n), where a is the number of subproblems, b is the size of each subproblem, and f(n) is the time to combine the subproblem solutions. The solution to this recurrence is T(n) = Θ(nlogba logn) if f(n) = Θ(nlogba) .

If the recurrence cannot be expressed in either of these forms, then the Master Theorem does not apply. In this case, other techniques such as substitution or recursion trees may be used to solve the recurrence.

To maintain a margin of error of 0.05 or less with a 99% confidence level, the polling company Five Thirty Eight must survey a minimum of 1068 consumers.

To find the minimum sample size required for a margin of error of 0.05 or less with a 99% confidence level, we can use the formula:

n = (z^2 * p * q) / E^2

where

z = the z-score associated with the desired confidence level (2.58 for 99%)

p = the estimated proportion of the population that has the attribute being measured (0.5 for maximum margin of error)

q = 1 - p

E = the desired margin of error (0.05)

Substituting the values, we get

n = (2.58^2 * 0.5 * 0.5) / 0.05^2

n = 1067.44

Rounding up to the nearest whole number, we get a minimum sample size of 1068 consumers that Five Thirty Eight should survey to guarantee a margin of error of 0.05 or less with a 99% confidence level.

The solution to the initial-value problem 5y'' y' = −4x is y = -4x^2 - 75e^(-x/5), and this is the function that satisfies the differential equation with the given initial conditions.

To solve the given initial-value problem, we need to use the method of undetermined coefficients to find a particular solution and the complementary solution to get the general solution.

First, we assume a particular solution of the form y₁ = Ax + B, where A and B are constants to be determined. Taking the first and second derivatives of y₁, we get y'₁ = A and y''₁ = 0. Substituting these into the differential equation, we get 5(0) + A = -4x, which gives A = -4x. Therefore, the particular solution is y₁ = -4x^2 + B.

Next, we find the complementary solution by solving the associated homogeneous differential equation, which is 5y'' + y' = 0. To solve this, we assume a solution of the form y₂ = e^(rx), where r is a constant to be determined.

Substituting this into the differential equation, we get the characteristic equation 5r^2 + r = 0, which has roots r = 0 and r = -1/5. Therefore, the complementary solution is y₂ = C1 + C2e^(-x/5).

Using the initial conditions y(0) = 0 and y'(0) = -15, we can solve for the constants B, C1, and C2. Substituting y(0) = 0 into the general solution y = y₁ + y₂, we get B + C1 = 0, which gives B = -C1.

Next, we differentiate y₁ to get y'₁  = -8x, and substitute y'(0) = -15 into the general solution y = y₁ + y₂, we get -8(0) + C2(-1/5) = -15, which gives C2 = 75.

Finally, we substitute B = -C1 and C2 = 75 into the general solution y = y₁ + y₂, we get y = -4x^2 - 75e^(-x/5).

Step-by-step explanation:

The slope of Line 1 is equal to 7.

The slope of Line 1 is equal to 1/7.

Line 1 and Line 2 are neither parallel nor perpendicular.

In Mathematics and Geometry, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

For line 1, we have the following:

Slope (m) = (32 - (-45))/(5 - (-6))

Slope (m) = (32 + 45)/(5 + 6)

Slope (m) = 77/11

Slope (m) = 7.

For line 2, we have the following:

Slope (m) = (43/7 - (-48/7))/(1 - 6)

Slope (m) = (-5/7)/(-5)

Slope (m) = 5/35

Slope (m) = 1/7

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

Answer:

The true statements are:

Step-by-step explanation:

Given table displaying the counts of how many songs of each genre were played in an hour from Josiah's MP3 player:

[tex]\begin{array}{|l|c||l|c|}\cline{1-4}\vphantom{\dfrac12}\sf Sample \;1&\phantom{www} &\sf Sample\;2&\phantom{www} \\\cline{1-4}\vphantom{\dfrac12}\textsf{R\&B} &5 & \textsf{R\&B} & 4\\\cline{1-4}\vphantom{\dfrac12}\sf Pop & 4 &\sf Pop & 3\\\cline{1-4}\vphantom{\dfrac12}\sf Classical & 3 & \sf Classical & 5\\\cline{1-4}\vphantom{\dfrac12}\sf Jazz & 2 & \sf Jazz & 4\\\cline{1-4}\vphantom{\dfrac12}\sf Rock & 6 & \sf Rock & 4\\\cline{1-4}\end{array}[/tex]

The total number of songs in Sample 1 is 20, of which 6 are rock songs.

The total number of songs in Sample 2 is 20, of which 4 are rock songs.

Josiah's work to predict the number of rock songs he has on his MP3 player given he has a total of 1,500 songs on his player:

[tex]\dfrac{10}{20}=\dfrac{x}{1500}[/tex]

[tex]\dfrac{10 \times 30}{20 \times 30}=\dfrac{x}{1500}[/tex]

[tex]300=x[/tex]

The total number of rock songs from both samples is 10. So there are 10 rock songs from a total sample of 40 songs.

As Josiah used a total sample of 20 songs in his calculations, he should have found the average of the number of rock songs by averaging 4 and 6 to get 5.

Looking at Josiah's calculations, he did not multiply the numerator and denominator by the correct number to equal 1,500.  He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

The correct work is as follows:

[tex]\dfrac{5}{20}=\dfrac{x}{1500}[/tex]

[tex]\dfrac{5\times 75}{20 \times 75}=\dfrac{x}{1500}[/tex]

[tex]375=x[/tex]

Therefore, the number of predicted rock songs on Josiah's MP3 player is 375.

Therefore, the true statements about his solution are:

A. The required vectors to component form as:  -7(u • v) = -21√(6).

B. u and w are neither parallel nor orthogonal.

Part A:

The vectors are given as:

u = −2(cos 30°i + sin30°j),

v = 6(cos 225°i + sin225°j),

w = 8(cos 120°i + sin120°j)

So we have:

u = -2(√(3)/2 i + 1/2 j) = -√(3) i - j

v = 6(-√(2)/2 i - sqrt(2)/2 j) = -√(2) i - √(2) j

w = 8(-1/2 i + √(3)/2 j) = -4i + √(3) j

To find -7(u • v), we first need to find the dot product of u and v:

u • v = (-√(3))( -√(2) ) + (-1)(-√(2)) = √(6)

Then, we can multiply by -7:

-7(u • v) = -7(√(6)) = -√(6)

Therefore, -7(u • v) = -21√(6).

Part B:

To determine if u and w are parallel, orthogonal, or neither, we can use the dot product:

u • w = (-√(3))(-4) + (-1)(4√(3)) = -8√(3)

Since the dot product is not equal to 0, we know that u and w are not orthogonal. To determine if they are parallel, we can compare their direction vectors:

The direction vector of u is < -√(3), -1 >, and the direction vector of w is < -4, 4√(3) >.

If u and w are parallel, then their direction vectors will be scalar multiples of each other.

So we need to check if there exists a scalar k such that:

< -√(3), -1 > = k < -4, 4√(3) >

This is equivalent to the system of equations:

-k × 4 = -√(3)

k × 4√(3) = -1

Solving for k, we get:

k = √(3)/12

Since k is not a real number, we know that u and w are not parallel.

Therefore, u and w are neither parallel nor orthogonal.

To determine whether the sequence is bounded, we can consider its behavior as n gets larger and larger. As n increases, 2^n grows exponentially, which means that a_n will also grow exponentially. However, no matter how large n gets, there will always be a constant term of 8 added to the result, which means that the sequence will never become unbounded. In other words, the sequence is both monotonic and bounded.

To determine the boundedness and monotonicity of the sequence a_n = 2^n + 8, n≥1, we can start by considering its first few terms:
a_1 = 2^1 + 8 = 10
a_2 = 2^2 + 8 = 12
a_3 = 2^3 + 8 = 16
a_4 = 2^4 + 8 = 24

To find the length of the polar curve given by r=7cos^4(θ/4), we use the formula:

L = ∫(a to b) √[r(θ)^2 + (dr/dθ)^2] dθ

where a and b are the limits of integration.

First, we need to find the derivative of r(θ):

dr/dθ = -7cos^3(θ/4)sin(θ/4)

Next, we can substitute r(θ) and dr/dθ into the above formula and simplify:

L = [tex]\int\limits^{2 \pi}_0[/tex] √[7cos^8(θ/4) + 49cos^6(θ/4)sin^2(θ/4)] dθ

L = 7[tex]\int\limits^{2 \pi}_0[/tex] cos^4(θ/4)√[1 + 7sin^2(θ/4)] dθ

Next, we use the substitution u = sin(θ/4), du/dθ = 1/4cos(θ/4), and simplify:

L = 28[tex]\int\limits^1_0[/tex] (1-u^2)^(3/2)√[1+7u^2] du

Now, we can use the substitution v = (1-u^2)^(1/2), dv = -u/[(1-u^2)^(1/2)] du, and simplify:

L = 28[tex]\int\limits^1_0[/tex] v^2(1-v^2)√[8v^2+1] dv

Step-by-step explanation:

Answer:

Without additional context or information, it's difficult to determine the missing side length with certainty. However, we can use some logical reasoning to make an educated guess.

One possible way to approach this problem is to look for relationships between the known side lengths and the missing side length. For example, we can look at the lengths of the sides that are adjacent to the missing side and see if there are any patterns or ratios that might help us determine the length of the missing side.

In this case, we can see that the missing side is adjacent to sides with lengths of 8 and 9, which have a difference of 1. If we assume that the sides of the figure form a regular pattern or sequence, then we might guess that the missing side has a length that is 1 greater than 9, which would give us a length of 10 for the missing side.

However, this is just a guess based on the limited information provided, and there could be other possible solutions depending on the specific properties or context of the figure.

Answer:
