Answers

Answer 1

\(w=3units\\a=120^\circ\\x=3\sqrt3units\\b=8.8units\\y=6units\\c=10^\circ\\z=60^\circ\\d=2.0units\\\text{perimeter of hexagon}=36units\\\text{area of hexagon}=54\sqrt3\text{ sq.units}\\\text{perimeter of traingle}=20.8units\\\text{area of traingle}=7.7\text{ sq.units}\)

The length of a side of the regular hexagon is \(6units\).

For \(w\):

Since the perpendicular line, \(x\), passes through the center of the hexagon, it bisects the side on which \(w\) lies. Therefore,

\(w=\dfrac{1}{2}\times \text{side}\\=\dfrac{1}{2}\times 6units=3units\)

For \(x\), \(y\), and \(z\):

The line \(x\) is perpendicular to the side of the hexagon and bisects a side of the hexagon.

The line \(y\) passes through the center of the hexagon, hence it bisects the interior angle of the hexagon. Also,

\(y=6units\)

since it is half the diagonal of the hexagon. The diagonal is twice the side-length.

To calculate the size of an interior angle of a hexagon, we use the formula

\(2z=\dfrac{180^\circ(n-2)}{n}\)

Each interior angle is twice \(z\). Since \(n=6\)

\(2z=\dfrac{180^\circ(6-2)}{6}\\\\2z=\dfrac{180^\circ\times4}{6}\\\\z=60^\circ\)

The lines \(x\), \(y\), and \(w\) form a right-angled triangle. Using Pythagoras theorem,

\(w^2+x^2=y^2\\3^2+x^2=6^2\\x^2=36-9=27\\x=3\sqrt3units\)

For \(a\):

\(a\) is an interior angle of the hexagon. Previously, we found that the interior angle

\(2z=a=120^\circ\)

For \(c\):

We have the relationship for the sum of the interior angles for the irregular triangle

\(50^\circ+120^\circ+c=180^\circ\)

the angle \(120^\circ\) is vertically opposite \(a\)

\(c=180^\circ-120^\circ-50^\circ=10^\circ\)

For \(b\):

Using the sine rule on the irregular triangle,

\(\dfrac{b}{sin50^\circ}=\dfrac{10}{sin120^\circ}\\\\b=\dfrac{10}{sin120^\circ}\times sin50^\circ\approx 8.8units\)

For \(d\):

\(\dfrac{b}{sin50^\circ}=\dfrac{d}{sin(c)}\\\\d=\dfrac{b}{sin50^\circ}\times sin(c)\\\\=\dfrac{8.8}{sin50^\circ}\times sin10^\circ\\\\\approx2.0units\)

The perimeter of the hexagon is

\(6\times \text{side}=6\times6=36units\)

The area of the hexagon is

\(6\times\dfrac{1}{2}\times \text{base}\times\text{height}\\\\3\times6\times x=3\times6\times 3\sqrt3\\=54\sqrt3\text{ sq.units}\)

perimeter of the triangle is

\(10+b+c=10+8.8+2.0\\=20.8units\)

area of the triangle is

\(\dfrac{1}{2}\times d\times 10sin50^\circ\\\\=\dfrac{1}{2}\times 2.0\times 10sin50^\circ\\\\\approx7.7\text{ sq.units}\)

Consider the following.
cos(x) = x3
A) Prove that the equation has at least one real root.
The equation cos(x) = x3 is equivalent to the equation f(x) = cos(x) − x3 = 0. f(x) is continuous on the interval (0, 1) there is a number c in (0, 1) such that f(c) = 0 by the Intermediate Value Theorem. Thus, there is a root of the equation cos(x) = x3, in the interval (0, 1).
B) Use your calculator to find an interval of length 0.01 that contains a root.

Answers

Answer:

Step-by-step explanation:

Given that:

cos(x) = x³

f(x) = cos (x) - x³

f(x) is continuous on the interval (0, 1)

when;

f(0) = cos (0) - (0)

f(0) = 1 - 0

f(0) = 1 > 0

f(1)  = cos (1) - 1³

f(1) = 0.5403 - 1

f(1) = -0.4597

f(1) = - 0.46

f(1) = - 0.46 < 0

Since, 1 > 0 > -0.46, thus there is a number ''c" in (0,1)

such that f(c) = 0

By applying the Intermediate Value Theorem, there is a root of the equation in the interval (0,1)

b) Given that:

The interval length = 0.01; this implies that it is 0.005 length from its root.

f(0.865) = 0.0014

f(0.87) = - 0.013

The solution to the interval lies between 0.865 , 0.87 by using a calculator at length 0.01.

Which is the first step in simplifying the expression 2(x 3) 5? 2x 2(3) 5 2x 3 5 2 x 3 5 2(5) x 3

Answers

The first step in simplifying the expression 2(x+3)+5 = 2x+2(3)+5.

Given expression in 'x' is 2(x+3)+5.

In order to simplify this expression, we need to expand it by opening the parenthesis. That is, we need to distribute 2 over (x+3) first. For this we multiply 2 into (x+3) and then only we can add 5 to it.

So, 2(x+3) +5 = 2x + 2(3) +5

A, B and C are the vertices of a triangle.
A has coordinates (4, 6)
B has coordinates (2,-2)
C has coordinates (-2,-4)
D is the midpoint of AB.
E is the midpoint of AC.
Prove that DE is parallel to BC.
You must show each stage of your working.

Answers

The proof of DE is parallel to BC in the given triangle is shown.

What is defined as the parallel line?Parallel lines are defined as two lines that remain the same distance away and never intersect. To be parallel, two lines must be driven in the same plane, which is a perfectly flat surface such as a wall or sheet of paper.

As per the given data in the question;

A, B and C are the vertices of a triangle.

A has coordinates (4, 6)B has coordinates (2,-2)C has coordinates (-2,-4)

Whereas,

D lies at the midpoint of AB.

E lies at  the midpoint of AC.

The mid piont formula is;

Mid point = (x₁ + x₂ / 2, y₁ + y₂ / 2)

The coordinates of D is found by the mid point formula of coordinates.

Put the coordinates of A (4, 6) and B (2,-2).

D = (4 + 2 / 2, 6 - 2 / 2)

D = (3, 2)

The coordinates of E is found by the mid point formula of coordinates.

Put the coordinates of A (4, 6) and C (-2,-4)

E = (4 - 2 / 2, 6 - 4 / 2)

E = (1, 1)

Now, the slope is calculated by;

m of DE = (y₂ -  y₁)/(x₂ - x₁)

The slope of E is

m of DE = (1 - 2)/(1 - 3) = 1/3

Slope of BC

M of BC = (-4 + 2)/(-4 - 2)

M of BC = 1/2

As, the slope of both line DE and BC are equal. Thus, both line are parallel to each other.

If sets A and B have the same number of terms, is the standard deviation of set A greater than the standard deviation of set B? 1.The range of set A is greater than the range of set B. 2. Sets A and B are both evenly spaced sets.

Answers

Step-by-step explanation:

(1) The range of set A is greater than the range of set B.

This statement  gives only the range which means only outermost values but what about the other values. For example-11,0,0,0,11 and -10,-10,0,10,10

Clearly, Former one has higher range but lower standard deviation.

(2) Sets A and B are both evenly spaced sets.

Evenly spaced is fine. However, we don't know the spacing since that is required to know the deviation.

For, example, sets A{2,4,6,8,10} and B {1,2,3,4,5} so in this case SD of A> SD of B. Or,  we can have B{2,4,6,8,10} and A{1,2,3,4,5} so in this case SD of B> SD of A.

Provide detailed answers including graphs for the following questions.
You invest $100,000 on January 1st in a lottery. The lottery provides you a 2% chance of winning $1 million on December 31st in each of the next 10 years. Are there any conditions under which would you make this investment?
A monopolist’s cost structure is such that its total costs are TC = 300 + 200Q + 3Q^2. The market demand is Q = 500 - P. What is the profit-maximizing price and quantity? Show this mathematically and graphically. What are the producer and consumer surpluses and firm profit?

Answers

The profit-maximizing price and quantity for the monopolist are $350 and 150 units, respectively ,The expected return is greater than the initial investment And the producer surplus is $33,750, consumer surplus is $31,875, and firm profit is $37,500.

Ignoring the time value of money and discounting, the expected value of the lottery winnings each year is 2% × $1 million = $20,000, and this goes on for 10 years.

Thus, the expected value of the investment is 10 × $20,000 = $200,000.

Hence, the expected return is greater than the initial investment, and there is a condition under which the investment can be made.

The monopolist’s total cost can be represented as:

TC = 300 + 200Q + 3Q².

The demand function for the monopolist is given as:

Q = 500 - P,

which can be rearranged to derive the price function as:

P = 500 - Q.

From the total cost function, we can obtain the marginal cost (MC) as the derivative of TC with respect to Q, and it can be represented as follows:

MC = dTC/dQ = 200 + 6Q.

From the marginal cost, we can set the marginal revenue (MR) equal to MC to get the profit-maximising quantity as follows:

MR = dTR/dQ = P + Q(500 - P) = 500 - Q + 500Q - Q² = 1000Q - Q² - 500 = MC = 200 + 6Q.

Substituting P = 500 - Q in the above expression and rearranging yields the following:

Q = 150, and hence, P = $350.

Therefore, the profit-maximising price is $350, and the quantity is 150. We can verify that the solution is a maximum by computing the second-order condition, which is negative.

To calculate the producer surplus, we first need to obtain the area above the marginal cost and below the price.

Thus, we have:

PS = ∫ MC to QdQ

= ∫ (200 + 6Q) dQ from 0 to 150

= [200Q + 3Q²] from 0 to 150

= $33,750.

Similarly, the consumer surplus can be computed as the difference between the market value of the product and what the consumers paid for it. The area below the price line and above the demand curve yields the consumer surplus.

Thus, we have:

CS = ∫ P to QdQ

= ∫ (500 - Q) dQ from 0 to 150

= [(500 × Q) - (Q²/2)] from 0 to 150

= $31,875.

Finally, the firm profit can be obtained by multiplying the profit-maximizing quantity by the profit-maximizing price and subtracting the total cost.

Thus, we have:

Profit = TR - TC = Q × P - TC = (150 × $350) - (300 + 200 × 150 + 3 × 150²) = $37,500.

Hence, the producer surplus, consumer surplus, and firm profit are $33,750, $31,875, and $37,500, respectively.

Answers

If Lucinda used a random selection method, made an effort to ensure that the sample is representative, and the sample size is large enough, then it's possible that the sample is indeed random.

what are perpendicular lines?

Perpendicular lines are two lines that intersect at a 90-degree angle, forming four right angles at the point of intersection. In other words, if you were to draw a perpendicular line from one of the lines to the other at their point of intersection, it would form a right angle with each of the original lines.

Without having access to more information about how Lucinda selected the sample of students, it's difficult to determine whether or not the sample is truly random.

However, there are a few things that we can consider when trying to determine whether or not the sample is random. For example:

Did Lucinda use a random selection method to choose the students? If she simply surveyed her friends or classmates, for example, the sample would not be random.

Did Lucinda make any effort to ensure that the sample is representative of the larger population of students? For example, did she make sure to include students from a variety of grades, genders, and ethnic backgrounds.

Therefore, if Lucinda used a random selection method, and made an effort to ensure that the sample is representative, and the sample size is large enough, then it's possible that the sample is indeed random.

Answers

The conclusion is Option (b) strong positive correlation between the number of churches and the number of violent crimes, but we cannot infer causation due to the presence of a confounding variable.

Correlation refers to the relationship between two variables, where a change in one variable may be associated with a change in the other variable.

The correlation coefficient, denoted by r, measures the strength and direction of the relationship between two variables. The value of r ranges from -1 to +1, where a value of -1 indicates a perfect negative correlation, a value of +1 indicates a perfect positive correlation, and a value of 0 indicates no correlation.

In this case, the correlation coefficient between the number of churches and the number of violent crimes is 0.85.

However, we cannot conclude that there is a causal relationship between the number of churches and the number of violent crimes committed in a city.

There may be a confounding variable, which is a third variable that affects both the independent and dependent variables.

Therefore, the correlation between the number of churches and the number of violent crimes may be spurious, meaning that it is not a true causal relationship but rather a result of the influence of a third variable.

Central conservative forces: (a) Consider the force F= r2kr^ : Is this force conservative? Is it central? If it is conservative find the potential energy V(r). For full marks you need to justify your answer and explain any assumptions that you make.

Answers

The force F = r^2k(r^) is not conservative because its curl is nonzero. The force is central because it depends only on r and acts along the radial direction. Since it is not conservative, there is no potential energy function V(r) associated with this force

To determine whether the force F = r^2k(r^) is conservative and central, let's analyze its properties.

A force is conservative if it satisfies the condition ∇ × F = 0, where ∇ is the gradient operator. In Cartesian coordinates, the force can be written as F = Fx i + Fy j + Fz k, where Fx, Fy, and Fz are the components of the force in the x, y, and z directions, respectively. The curl of F is given by:

∇ × F = (∂Fz/∂y - ∂Fy/∂z)i + (∂Fx/∂z - ∂Fz/∂x)j + (∂Fy/∂x - ∂Fx/∂y)k.

Calculating the components of F = r^2k(r^):

Fx = 0, since there is no force component in the x-direction.

Fy = 0, since there is no force component in the y-direction.

Fz = r^2kr^.

Taking the partial derivatives, we have:

∂Fz/∂x = ∂/∂x (r^2kr^) = 2rkr^2(∂r/∂x) = 2rkr^2(x/r) = 2xkr^3.

∂Fz/∂y = ∂/∂y (r^2kr^) = 2rkr^2(∂r/∂y) = 2rkr^2(y/r) = 2ykr^3.

Substituting these values into the curl equation, we get:

∇ × F = (2ykr^3 - 2xkr^3)k = 2k(r^3y - r^3x).

Since the curl of F is not zero, ∇ × F ≠ 0, we conclude that the force F = r^2k(r^) is not conservative.

Now let's determine if the force is central. A force is central if it depends only on the distance from the origin (r) and acts along the radial direction (r^).

For F = r^2k(r^), the force is indeed central because it depends solely on r (the magnitude of the position vector) and acts along the radial direction r^. Hence, it can be written as F = Fr(r^), where Fr is a function of r.

Since the force is not conservative, it does not possess a potential energy function. In conservative forces, the potential energy function V(r) can be defined, and the force can be expressed as the negative gradient of the potential energy, i.e., F = -∇V. However, since F is not conservative, there is no potential energy function associated with it.
