Answer:

Sum of the interior angles = 2,880° Therefore, assuming a convex or regular polygon and using the summation formula (n - 2) 180°, we have

(n - 2) 180° = 2,880° Solve for n

n - 2 = 16 Add 2 to both sides of the equation

n = 18

Step-by-step explanation:

(n - 2) 180° = 2,880° Solve for n

n - 2 = 16 Add 2 to both sides of the equation

Answer:

180 customers made additional purchases

Step-by-step explanation:

In order to find the percent of something like 72% of 250 you need to convert the percentage to a decimal and multiply it to the number.

0.72 * 250 = 180

Answer:

180 customers

Step-by-step explanation:

Since 72% of the customers made additional purchases and there were 250 customers, we need to look for 72% of 250. To do this we convert 72 into a fraction, which makes it 0.72 and we turn the word "of" into a multiplication symbol (as of most commonly means multiplication in math). So, 0.72*250=180. Therefore, 180 customers made additional purchaces.

Answer: (2y-3x)/(2y+3x), domain is y ≠ 1.5x

Step-by-step explanation:

9x^2 + 4y^2 - 12xy is a perfect square, simplifying to (2y-3x)^2 or (3x-2y)^2, order doesn't matter but we keep the first one because it simplifies later.

4y^2 - 9x^2 is a difference of two squares simplifying to (2y+3x)(2y-3x)

Our equation is now ((2y-3x)^2)/(2y+3x)(2y-3x)

Then, we can cross out one of the (2y-3x) from both sides, to simplify down to (2y-3x)/(2y+3x).

Now, to find domain, since we removed a value from the denominator, we have to specify that in the domain, this case being 2y -3x ≠ 0, which is y ≠ 1.5x

This is the desired 4x4 matrix that produces the translation by the vector (4,-6,-3) using homogeneous coordinates.

To find the 4x4 matrix that produces a translation by the vector (4,-6,-3) using homogeneous coordinates, we start with the identity matrix:

[1 0 0 0]
[0 1 0 0]
[0 0 1 0]
[0 0 0 1]

We then replace the last column with the translation vector in homogeneous coordinates, which is [4, -6, -3, 1]:

[1 0 0 4]
[0 1 0 -6]
[0 0 1 -3]
[0 0 0 1]

The correct statements regarding the relationship of pH and pKa are: When pKa > pH, then [A-]/[HA] < 1 and [A-] > [HA] & When pH - pKa > 0, then [A-]/[HA] < 1 and [HA] > [A-].

Statement a is incorrect because it does not provide enough information to determine the relationship between pH and pKa.

Statement b is incorrect because it only mentions pH and [A-], but does not provide any information about the concentration of [HA] or the pKa.

Statement e is incorrect because it does not provide any information about the concentrations of [HA], [A-], or the pKa.

The correct statements (c and d) describe the relationship between the acid dissociation constant (pKa), the pH, and the relative concentrations of the acid (HA) and its conjugate base (A-).

When the pKa is greater than the pH, it indicates that the acid is mostly in its undissociated form (HA) and the concentration of the conjugate base ([A-]) is lower than the concentration of the acid ([HA]).

The distance from the bird to the top of the tree is 61.95 feet.

We have,

Angle of elevation to the top of the tree: 38 degrees.

Angle of elevation to the bird: 60 degrees.

Distance from the base of the tree to your position: 84 feet.

Let the distance from the bird to the top of the tree as 'x'.

Using Trigonometry

tan(38) = height of the tree / 84

height of the tree = tan(38) x 84

and, tan(60) = height of the tree / x

x = height of the tree / tan(60)

Substituting the value of the height of the tree we obtained earlier:

x = (tan(38) x 84) / tan(60)

x ≈ 61.95 feet

Therefore, the distance from the bird to the top of the tree is 61.95 feet.

In 2006, the five mainline Protestant churches accounted for 83% of the total Protestant membership.

In 2006, the combined membership of the five mainline Protestant churches (Baptist, Episcopal, Lutheran, Methodist, and Presbyterian) was approximately 65% of the total Protestant membership. This can be expressed as a formula:

Proportion of Mainline Protestant Membership = (Baptist Membership + Episcopal Membership + Lutheran Membership + Methodist Membership + Presbyterian Membership) / Total Protestant Membership

To calculate the proportion of mainline Protestant membership in 2006, we can apply the formula:

Proportion of Mainline Protestant Membership = (9,277,000 + 2,231,000 + 5,255,000 + 8,422,000 + 2,866,000) / (14,280,000 + 9,277,000 + 2,231,000 + 5,255,000 + 8,422,000 + 2,866,000)

Proportion of Mainline Protestant Membership = 29,106,000 / 35,050,000

Proportion of Mainline Protestant Membership = 0.83, or 83%

Therefore, in 2006, the five mainline Protestant churches accounted for 83% of the total Protestant membership.

Value if p is $16 which maximizes the total revenue.

We need to first find the total revenue equation and then maximize it. Here are the steps:

Step 1: Write the demand equation.
x = 960 - 30p

Step 2: Write the total revenue equation.
Total Revenue (R) = price (p) × quantity (x)
R = px

Step 3: Substitute the demand equation into the total revenue equation.
R = p(960 - 30p)

Step 4: Simplify the total revenue equation.
R = 960p - 30p²

Step 5: Differentiate the total revenue equation with respect to p.
dR/dp = 960 - 60p

Step 6: Set the derivative equal to zero to find the critical points.
0 = 960 - 60p

Step 7: Solve for p.
60p = 960
p = 960/60
p = 16

So, the value of p that maximizes the total revenue is $16.

This estimation is speculative and may not accurately reflect the actual probability in the given context.

To determine the probability that a person is using a 3-month new member discount given that they have been a member for more than a year, we would need additional information such as the total number of members, the number of members using the discount, and the distribution of membership lengths.

Without this information, it is not possible to calculate the probability directly. However, we can make some assumptions to provide a general idea.

Assuming that the new member discount is only available to new members for the first three months of their membership and that the number of members who have been a member for more than a year is significant, we can estimate that the probability of a person using the 3-month new member discount in this scenario is likely to be low.

This assumption is based on the understanding that the longer a person has been a member, the less likely they are to still be eligible for or make use of a new member discount.

It's important to note that without specific data or a more detailed understanding of the membership characteristics and behavior, this estimation is speculative and may not accurately reflect the actual probability in the given context.

The total value of the income stream would be $187,500.

WE are given that integral of R(t) with respect to t ∫[0,5] R(t) dt = ∫[0,5] (30,000 + 3,000t) dt

To determine the total value of the income stream, we need to evaluate the definite integral of the function R(t) over the given interval. The integral of R(t) with respect to t is:

∫[0,5] R(t) dt = ∫[0,5] (30,000 + 3,000t) dt

Evaluating this integral gives:

∫[0,5] R(t) dt = (30,000t + 1,500t²) [0,5]

= (30,000(5) + 1,500(5²)) - (30,000(0) + 1,500(0²))

The transformation needed to go from the graph of the basic function f(x) = √x to the graph of g(x) = -√ (x - 10) is option D.

Reflect across the x-axis, and shift left 10 units.

Reflect across the x-axis, and shift left 10 units is correct because

g(x) = -√ (x - 10) is a reflection of the basic function f(x) = √x across the

x-axis and a shift of 10 units to the right along the x-axis.

Let's examine these transformations in detail;

If we take the basic function f(x) = √x, and reflect it across the x-axis, we get the graph of g(x) = -√x.

We get the reflection because the negative sign (-) means we flip the graph over the x-axis, this changes the sign of the y-coordinate of each point of the graph.

The shift of 10 units to the right along the x-axis is achieved by replacing x in the basic function with (x - 10), that is;

f(x) becomes f(x - 10),

which in this case will be g(x) = -√ (x - 10).

Hence, option D is the correct answer.

You can put 14 boxes of candy weighing 3/4 lb each in the bin.

To determine how many 3/4 lb boxes of candy can fit in a bin, we divide the total weight of the bin by the weight of each box.

First, let's convert the mixed number 10 1/2 lbs to an improper fraction.

10 1/2 lbs = (10 * 2 + 1) / 2 = 21/2 lbs

Next, we divide the total weight of the bin (21/2 lbs) by the weight of each box (3/4 lb):

(21/2 lbs) / (3/4 lb) = (21/2) * (4/3) = (21 * 4) / (2 * 3) = 84/6 = 14

As a result, you can fill the bin with 14 boxes of sweets that each weigh 3/4 lb.

W and is orthogonal to all vectors in W except itself, we have shown that any vector in Rn can be written as a linear combination of the n non-zero orthogonal vectors that span W, and hence W=Rn.

To show that W=Rn, we need to show that any vector in Rn can be written as a linear combination of the n non-zero orthogonal vectors that span W.

Let v be any vector in Rn. Since the n non-zero orthogonal vectors span W, we can write v as a linear combination of them:

v = c1v1 + c2v2 + ... + cnvn

where c1, c2, ..., cn are scalars, and v1, v2, ..., vn are the n non-zero orthogonal vectors that span W.

To show that v is in W, we need to show that v is orthogonal to all vectors in W except itself. Since the n non-zero orthogonal vectors are linearly independent, any linear combination of them that is orthogonal to v must be the zero vector.

Therefore, if w is any vector in W that is not equal to v, we have:

=  = c1 + c2 + ... + cn = 0

since v is orthogonal to all the non-zero orthogonal vectors. This means that v is orthogonal to all vectors in W except itself.

Therefore, since v is in W and is orthogonal to all vectors in W except itself, we have shown that any vector in Rn can be written as a linear combination of the n non-zero orthogonal vectors that span W, and hence W=Rn.
