A) friendly.
B) curious.
C) disobedient.
D) judgmental.
Answers
The narrator uses the phrase "making trial of everything" from the passage to present Eppie as curious. The correct option is B.
Given a passage which is shown in attached images.
Option B is the best answer. The first paragraph describes Eppie as "a creature of endless dreams and ever-increasing desires", someone who "tried everything to the test". In this context, his "trying everything" can be read as acting on his curiosity by trying to experience the world around him.
Options A, C and D are incorrect because in the context of her "doing everything to check", Eppie could be seen as curious, unfriendly (option A), disobedient ( option C) or criticize (option D).
Hence, the narrator uses the phrase "making trial of everything" from the given passage to present Eppie as curious.

Consider a male restroom design with minimum plumbing requirements of 12 water closets and 13 lavatories, which one of the following is closest to the minimum space required with considering urinal substitution? Select one: O a. 222 b. 219 c. 237 d. 249
Answers
none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.
To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.
The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.
Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:
Minimum space required for water closets = 12 water closets * 30 inches = 360 inches
Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches
Adding these two values together, we get a total minimum space requirement of 672 inches.
Among the given options, the closest value to 672 inches is option d) 249. However, this value seems significantly lower than the expected minimum space requirement.

return 1
#Otherwise,
else:
#Count the number of integers

Partial Question 4 Determine the limit of the sequence (1) {2} [Select] n+3 (2) { (+³)"} [Select] (3) {n sin()} [Select] (4) {sin(nπ)} [Select] Answer 1: the limit DNE, the sequence diverges Answer
Answers
The limit of the sequence (1) {2}, (2) {(-1)^n}, and (3) {n sin(n)}, converges to DNE (does not exist) or the sequence diverges. The limit of the sequence (4) {sin(nπ)} is undefined, as it oscillates between -1 and 1.
In the case of sequence (1) {2}, the limit is a constant value, and the sequence converges to that value. However, in the case of sequence (2) {(-1)^n}, the sequence oscillates between -1 and 1, and there is no single value that it approaches as n tends to infinity. Therefore, the limit does not exist, and the sequence diverges.
Sequence (3) {n sin(n)} also does not have a limit as n tends to infinity. The term n sin(n) oscillates between positive and negative values without approaching a specific value. Hence, the limit of this sequence is DNE, and it diverges.
In the case of sequence (4) {sin(nπ)}, the term sin(nπ) oscillates between -1 and 1 as n varies. Since there is no convergence to a specific value, the limit of this sequence is undefined.

The general equation of the circle is given by:
\((x-h)^2+(y-k)^2=r^2\)
where,
(h, k) is the center of the circle and r is the radius of the circle.
As per the statement:
The center of a circle is at (−2, −7) and its radius is 6.
\(\implies (h, k) = (-2, -7)\) and \(r = 6\) units
Substitute these we have:

A monopolistically competitive firm is currently producing 30 units of output. At this level of output, the firm is charging the highest price it can at $30, has marginal revenue equal to $15, has marginal cost equal to $15, and has average total cost equal to $25. From this information, we can infer that:_____.a. the firm is earning zero profit. b. the firm is currently maximizing its profit. c. the profits of the firm are negative. d. firms are likely to leave this market in the long-run.
Answers
we can infer that the firm is currently maximizing its profit. Option (b), "the firm is currently maximizing its profit," is the most appropriate inference from the provided data.
To determine whether the firm is maximizing its profit, we need to analyze the relationship between marginal revenue (MR), marginal cost (MC), and price. In a monopolistically competitive market, firms aim to maximize their profit by producing at a level of output where MR equals MC.
From the information provided, we know that the firm's marginal revenue is equal to $15 and marginal cost is also equal to $15. This indicates that the firm is producing at the level where its marginal revenue equals its marginal cost, which is a characteristic of profit maximization.
Additionally, we are told that the firm is charging the highest price it can at $30. This means that the firm is able to set its price above its average total cost, resulting in a positive difference between price and average total cost, known as economic profit.

Given secant of theta is equal to the square root of 6 over 2 comma what is cos?
Answers
The value of cos θ is equal to 1/3 when sec θ= √6/2.
Since we are given the value of secant of theta, we can use the relationship between secant and cosine to find the value of cosine of theta.
Let's start by recalling the definitions of secant and cosine functions. The secant of an angle is defined as the reciprocal of the cosine of that angle.
In other words, secθ = 1/cosθ
Conversely, the cosine of an angle is defined as the reciprocal of the secant of that angle.
cosθ = 1/secθ
We are given that secθ= √6/2
We can use this value to find cosθ= 1/secθ
cosθ = 1 / (√6/2)
To simplify this expression, we can multiply both the numerator and denominator by 2/sqrt(6).
cosθ = ((2/√6) / (√6/2) * (2/√6))
cosθ = (2/√6) / 1
cosθ = (2/√6 * √6/√6)
cosθ = 2/6 = 1/3
Therefore, the value of cosθ is equal to 1/3 when secθ = sqrt(6)/2.

angles of a quadrilateral are y,2y,3y+20 and 4y+30 . find each angle if the sum of the angles of a quadrilateral is 360°
Answers
Answer:
31° , 62° , 113° , 154°
Step-by-step explanation:
sum the 4 angles and equate to 360
y + 2y + 3y + 20 + 4y + 30 = 360 , that is
10y + 50 = 360 ( subtract 50 from both sides )
10y = 310 ( divide both sides by 10 )
y = 31
2y = 2(31) = 62
3y + 20 = 3(31) + 20 = 93 + 20 = 113
4y + 30 = 4(31) + 30 = 124 + 30 = 154
the 4 angles are 31° , 62° , 113° , 154°
if force 1 = 258 newton with 45 mm length of vector, force2 = ?, length of vector = 28mm. what is force 2 equal to?
Answers
Force 2 has a magnitude of approximately 160.8 Newton.
To find the value of force2, we can use the concept of vector equivalence. If force1 has a magnitude of 258 Newton and a length of vector equal to 45 mm, and force2 has a length of vector equal to 28 mm, we can set up the following proportion:
|force1| / length of vector for force1 = |force2| / length of vector for force2
Substituting the given values:
258 / 45 = |force2| / 28
To solve for |force2|, we can cross-multiply and solve for it:
258 * 28 = 45 * |force2|
|force2| = (258 * 28) / 45
Calculating this expression gives us:
|force2| ≈ 160.8 Newton
Therefore, force2 has a magnitude of approximately 160.8 Newton.
