=27.3 degrees and r
2
=7.2 cm,θ

=74.9 degrees. What is the distance between the two points measured in inches?
The distance between the two points is approximately 1.802 inches.
To find the distance between two points in a two-dimensional polar coordinate system, we can use the formula:
\(\[d = \sqrt{{r_1^2 + r_2^2 - 2r_1r_2\cos(\theta_2 - \theta_1)}}\]\)
Given that \(\(r_1 = 6.1\)\) cm, \(\(\theta_1 = 27.3\)\) degrees, \(\(r_2 = 7.2\)\) cm, and \(\(\theta_2 = 74.9\)\) degrees, we can substitute these values into the formula to calculate the distance.
Converting the distance to inches, we can use the conversion factor 1 cm = 0.3937 inches.
Calculating the distance in inches:
\(\[d = \sqrt{{(6.1 \, \text{cm})^2 + (7.2 \, \text{cm})^2 - 2(6.1 \, \text{cm})(7.2 \, \text{cm})\cos(74.9^\circ - 27.3^\circ)}} \times 0.3937 \, \text{inches}\]\)
Simplifying the equation, we have:
\(\[d = \sqrt{{(37.21 \, \text{cm}^2) + (51.84 \, \text{cm}^2) - 2(6.1 \, \text{cm})(7.2 \, \text{cm})\cos(47.6^\circ)}} \times 0.3937 \, \text{inches}\]\)
Calculating further, we get:
\(\[d = \sqrt{{89.05 \, \text{cm}^2 - 87.84 \, \text{cm}^2 \cos(47.6^\circ)}} \times 0.3937 \, \text{inches}\]\)
Finally, evaluating the expression, we find:
\(\[d \approx 1.802 \, \text{inches}\]\)
Therefore, the distance between the two points is approximately 1.802 inches.

Find the distance between the foci of an ellipse. The lengths of the major and minor axes are listed respectively.
18 and 14
The distance between the foci of the ellipse is approximately 5.66 units.
To find the distance between the foci of an ellipse, we can use the formula:
c = sqrt(a^2 - b^2)
where a is the length of the semi-major axis and b is the length of the semi-minor axis. In this case, the major axis has a length of 18 and the minor axis has a length of 14.
To find the value of c, we first need to find the values of a and b. The length of the major axis is twice the length of the semi-major axis, so a = 18/2 = 9. Similarly, the length of the minor axis is twice the length of the semi-minor axis, so b = 14/2 = 7.
Now, we can substitute these values into the formula:
c = sqrt(9^2 - 7^2)
= sqrt(81 - 49
) = sqrt(32)
≈ 5.66

Consider the triangle shown in the diagram below.Suppose that m∠A=80 degress, m∠C=35∘, and c=42.5. What is the value of a?a=Now, suppose that m∠B=52∘, m∠C=26∘, and a=19.3. What is the value of c?c=
a =72.97 and c=8.62
a) To find out the value of a let's use the Law of Sines. This way:
\(\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}\)And the fact that the sum of the interior angles within a triangle is always 180º so, m∠B =180-(80+35) , m∠B = 65º. Now let's plug that information into that:
\(\begin{gathered} \frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)} \\ \frac{a}{\sin(80)}=\frac{42.5}{\sin(35)} \\ a\sin (35)=42.5\cdot\sin (80) \\ a=\frac{42.5\cdot\sin(80)}{\sin(35)} \\ a\approx72.97 \end{gathered}\)b) Let's find the value of that angle A, at first. m∠A =180-(52+26), m∠A=102º
Likewise, we're going to adopt the same way to find the measure of leg c:
\(\begin{gathered} \frac{19.3}{\sin(102)}=\frac{c}{\sin (26)} \\ c=\frac{19.3\cdot\sin (26)}{\sin (102)} \\ c\approx8.65 \end{gathered}\)2) Hence, the answers are a =72.97 and c=8.62

Oliver's Flavored Popcorn comes in cylindrical tins divided into three equal sections of caramel, cheese, and buttered flavors. If the tin is 10 inches in diameter and 15 inches tall, what is the volume to the nearest tenth of only the cheese popcorn?
Answer:
The volume of only the cheese popcorn is 392.5 cubic inches.
Step-by-step explanation:
To determine the volume of only the cheese popcorn,
First, we will determine the volume of the cylindrical tin
The volume of a cylinder is given by
V = πr²h
Where V is the volume of the cylinder
π is a constant, (Take π = 3.14)
r is the radius of the cylinder
and h is the height of the cylinder
From the question, the tin is 10 inches in diameter and 15 inches tall.
Diameter = 10 inches, therefore, we can find radius
Radius = Diameter/2 = 10/2 = 5 inches
r = 5 inches
h = 15 inches
Now, putting the values into the equation, we get
V = 3.14 × 5² × 15
V = 1177.5 cubic inches
This is the volume of the cylindrical tin.
Since the cylindrical tin is divided into three equal sections of caramel, cheese, and buttered flavors, then the volume of only the cheese popcorn will be one-third of the total volume of the cylindrical tin.
∴ The volume of only the cheese popcorn = 1/3 × 1177.5 = 392.5 cubic inches
Hence, the volume of only the cheese popcorn is 392.5 cubic inches.
What is the probability that the weight of a bag will be greater than the maximum allowable weight of 50 pounds
The probability that the weight of a bag will be greater than the maximum allowable weight of 50 pounds depends on the distribution of bag weights and their relationship to the maximum weight limit.
To estimate the probability, we can assume a normal distribution for bag weights, with a mean and standard deviation. Let's denote the mean as μ and the standard deviation as σ. If we assume that bag weights follow a normal distribution, we can calculate the z-score for the maximum allowable weight of 50 pounds using the formula: z = (x - μ) / σ, where x is the maximum weight.
Next, we can use the z-score to determine the probability using the cumulative distribution function (CDF) of the standard normal distribution. The CDF gives the probability that a random variable is less than or equal to a certain value. In this case, we want to find the probability that the bag weight exceeds 50 pounds, which is equivalent to finding the probability that the random variable is greater than 50 pounds.
Since the CDF provides the probability of being less than or equal to a given value, we can subtract the result from 1 to obtain the probability of being greater than 50 pounds. This probability represents the likelihood of a bag exceeding the maximum allowable weight. However, keep in mind that these calculations are based on the assumption of a normal distribution, and the actual probability will vary depending on the specific characteristics of the bag weights distribution.

The computer club is purchasing 14 portfolios, 14 binders, 14 school
sweatshirts, 14 music cases, 14 phone cases, and 14 mouse pads. The club
will pay for 40% of the cost. The 14 members are equally responsible for the
rest of the cost. All items are taxable. How much will each member owe?
Let's calculate the total cost of all the items purchased by the computer club:
Cost of 14 portfolios = 14 * $24.59
Cost of 14 binders = 14 * $12.92
Cost of 14 school sweatshirts = 14 * $14.00
Cost of 14 music cases = 14 * $1.25
Cost of 14 phone cases = 14 * $1.99
Cost of 14 mouse pads = 14 * $2.14
Total cost of all items = Cost of 14 portfolios + Cost of 14 binders + Cost of 14 school sweatshirts + Cost of 14 music cases + Cost of 14 phone cases + Cost of 14 mouse pads
Plugging in the given values:
Total cost of all items = (14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14)
Now, the computer club will pay for 40% of the total cost. To calculate this, we can multiply the total cost by 40% (or 0.40):
Club's payment = 0.40 * Total cost of all items
The remaining cost will be divided equally among the 14 members:
Remaining cost per member = (Total cost of all items - Club's payment) / 14
Plugging in the values and calculating:
Club's payment = 0.40 * ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14))
Remaining cost per member = ((14 * $24.59) + (14 * $12.92) + (14 * $14.00) + (14 * $1.25) + (14 * $1.99) + (14 * $2.14) - Club's payment) / 14
So, each member of the computer club will owe the calculated value for "Remaining cost per member".

Bread Number sold banana 11 zucchini 8 cranberry 9 blueberry 14 Based on the data, what is the probability that the next loaf Roger sells will be zucchini bread? Write your answer as a fraction or whole number.
The probability of Roger selling a zucchini bread as the next loaf is 4/21.
What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
The probability of Roger selling a zucchini bread as the next loaf can be found by dividing the number of zucchini breads sold by the total number of breads sold so far.
The total number of breads sold so far is:
11 (banana) + 8 (zucchini) + 9 (cranberry) + 14 (blueberry) = 42
The number of zucchini breads sold is 8.
So the probability that the next loaf Roger sells will be zucchini bread is:
8/42 = 4/21
Therefore, the probability of Roger selling a zucchini bread as the next loaf is 4/21.

Combining Part 1 and Part 2, we conclude that A with the relative topology is locally compact.
To show that the closed subset A of a locally compact space (X, T) with the relative topology is locally compact, we need to prove two things: that A is locally compact and that it has the relative topology.
Let's break down the proof into two parts:
Part 1: A is locally compact
To show that A is locally compact, we need to prove that for every point x in A, there exists a compact neighborhood of x in A.
Since A is a closed subset of X, its complement X \ A is open in X. By the local compactness of X, for each x in A, there exists a compact neighborhood N of x in X. We can choose N such that N ∩ (X \ A) = ∅, i.e., N is disjoint from the complement of A.
Now, consider the intersection of A with N, denoted as N' = N ∩ A. Since N is compact and A is closed, the intersection N' = N ∩ A is closed in N. Moreover, since N is disjoint from X \ A, N' = N ∩ A is also disjoint from (X \ A) ∩ N, which is the complement of N' in N.
Therefore, N' is a compact neighborhood of x in A. Hence, A is locally compact.
Part 2: A has the relative topology
The relative topology on A is obtained by considering the subset A together with the open sets of X that intersect A. We need to show that the relative topology on A is the same as the topology induced by A as a locally compact space.
Let B be an open set in the relative topology on A. By definition, B = U ∩ A, where U is an open set in X.
We claim that U is also an open set in X with respect to the original topology T. Since X \ A is closed, its complement A = X \ (X \ A) is open. Therefore, U = U ∩ X = (U ∩ A) ∪ (U ∩ (X \ A)) = B ∪ (U ∩ (X \ A)), where B is open in A and U ∩ (X \ A) is open in X \ A. Thus, U is a union of two open sets in X, making it open.
Now, let's consider the topology induced by A as a locally compact space. In this topology, a set C is open in A if and only if C = V ∩ A, where V is an open set in A as a locally compact space.
Since V is open in A as a locally compact space, there exists a compact set K in A such that V contains an open set W in A, i.e., V = W ∪ (K ∩ A). Therefore, V = (W ∪ (K ∩ A)) ∩ A = (W ∩ A) ∪ ((K ∩ A) ∩ A) = W ∩ A.
As a result, the relative topology on A is the same as the topology induced by A as a locally compact space.
Combining Part 1 and Part 2, we conclude that A with the relative topology is locally compact.

If P(B)=0.3, P(A|B)=0.5, P(B')=0.7and P(A|B')=0.8, then the value of the probability P(B|A)= 0.2113
To find the value of P(B|A), follow these steps:
The probability of B given A can be given by the product of the probability of A given B and the probability of B, divided by the total probability of B. So, the formula for P(B|A) = P(A|B) * P(B) / [P(A|B)*P(B)+P(A|B')*P(B')]. Substituting the values, we get P(B|A) = (0.5) (0.3) / [(0.5) (0.3) + (0.8) (0.7)] ⇒P(B|A) = 0.15 / [0.15 + 0.56] ⇒P(B|A) = 0.15 / 0.71 ⇒P(B|A) = 0.2113.
