Assuming that the long-run demand for oranges is the same as the short-run demand, you would expect a binding price ceiling to result in a________ that is_________in the long run than in the short run.(Surplus/Shortage) (Larger/Smaller)
If the long-term demand for oranges is the same as the short-term demand, a binding price ceiling will result in a shortage that is larger in long-run demand than the short-run demand. So the answers are shortage and larger.
A shortage occurs when there is a difference between the quantity that is supplied and the quantity that is required of a product, service, or resource. Surplus is a term used to describe situations where there is more supply than demand for a product, service, or resource.
So when the long-run demand is the same as the short-run demand, binding price ceilings typically result in a shortage when there is a lack of supply of products. And, the result will be larger in the case of the long run compared to the short run. Therefore, the first blank can be filled with shortage and the second blank with larger.

Show that x=0 is a regular singular point of the given differential equation
b. Find the exponents at the singular point x=0.
c. Find the first three nonzero terms in each of two solutions(not multiples of each other) about x=0.
xy'' + y = 0
The first three nonzero terms of two linearly independent solutions about x = 0 can be obtained by Taylor expanding the solutions in terms of the exponent r and truncating the series to the desired order.
To determine if x = 0 is a regular singular point of the differential equation xy'' + y = 0, we substitute y = x^r into the equation and solve for the exponent r. Differentiating y twice with respect to x, we have y'' = r(r - 1)x^(r - 2). Substituting these expressions into the differential equation, we get \(x(x^r)(r(r - 1)x^(r - 2)) + x^r = 0\). Simplifying, we obtain r(r - 1) + 1 = 0, which yields r^2 - r + 1 = 0. Solving this quadratic equation, we find that the exponents at the singular point x = 0 are complex and given by r = (1 ± i√3)/2.
To find the first three nonzero terms of two linearly independent solutions about x = 0, we can use the Taylor series expansion. Let's consider the solution y1(x) corresponding to the exponent r = (1 + i√3)/2. Expanding y1(x) as a series around x = 0, we have y1(x) =\(x^r = x^((1 +\)i√3)/2) = x^(1/2) *\(x^(i√3/2\)). Using the binomial series expansion and Euler's formula, we can write \(x^(1/2) and x^(i√3/2)\) as infinite series.

Step-by-step explanation:
as a regular polygon (in our case 6 corners and sides) all sides are equally long, and all angles are also of equal size. so, the graphic is optically misleading.
so,
a) the congruent triangles are ABC, CDE and EFA.
b)i)
any internal angle of a regular polygon with n corners/angles is (n-2)×180/n.
our n here is 6.
angle ABC = (6-2)×180/6 = 4×30 = 120 degrees.
ii)
the sum of all angles in a triangle is 180 degrees.
the triangle ABC is an isoceles triangle (the legs are equally long), and so, both "side angles" are equal. and we know the angle ABC.
so,
180 = 120 + 2×side-angle
60 = 2×side-angle
side-angle = CAB = 60/2 = 30 degrees.
iii)
as we know that all inner angles of the regular polygon are equally sized, angle FAB = angle ABC = 120 degrees.
and angle FAE = angle CAB = 30 degrees.
so,
angle EAC = 120 - angle CAB - angle FAE =
= 120 - 30 - 30 = 60 degrees

A van travelled at an average speed of 65km/hr from town A. A 35 minutes later a car started from town A ans drove along the same route as the van.If the car caught up with the van after travelling a distance of 130km find the avg speed of the car
Answer:
91.6 km/h
Step-by-step explanation:
Let v = average speed of van = 65 km/h and v' = average speed of car. Let t be the time the car starts to move. The van started 35 minutes earlier at t' = (t + 35/60) h.
Since distance d = vt where v = velocity and t = time, the distance moved by the van d = vt' = v(t + 35/60) and that moved by the car is d' = v't.
Since the car catches up with the van after it had moved a distance of 130 km, d = d' = 130 km.
So d = v(t + 0.583)
Substituting d = 130 km and v = 65 km/h, we have
130 km = 65 km/h(t + 0.583)
130 km = (65t + 37.895 )km
subtracting 37.895 from both sides, we have
130 km - 37.895 km = 65t
92.105 = 65t
dividing both sides by 65, we have
t = 92.105/65
= 1.417 h
≅ 1.42 h
Since d = d' = v't,
v' = d'/t
= 130 km/1.42 h
= 91.55 km/h
≅ 91.6 km/h
So, the average speed of the car is 91.6 km/h

Based on the boxplot, the top 25 percent of the cars have a typical gas mileage of at least how many miles per gallon? responses.
The top 25% of cars have a typical gas mileage of at least 33.5 miles per gallon.
To calculate this, you need to use the interquartile range (IQR) formula.
The IQR is calculated by subtracting the 25th percentile (Q1) from the 75th percentile (Q3).
IQR = Q3 - Q1
In this case, the 25th percentile (Q1) is 28.4, and the 75th percentile (Q3) is 37.9. So:
IQR = 37.9 - 28.4 = 9.5
The top 25% of cars have a gas mileage of 33.5 miles per gallon, which is Q3 + 1.5*IQR.
33.5 = Q3 + 1.5*IQR
33.5 = 37.9 + 1.5*9.5
33.5 = 37.9 + 14.25
33.5 = 52.15
Therefore, the top 25 percent of cars have a typical gas mileage of at least 33.5 miles per gallon.

What is the crossover point for these processes?
Every year, 1800 units crossover point. The process focus is less expensive for volumes over 1800.
What is the crossover point?When all tax credits have been used up by a limited partnership and the limited partners are left with a tax burden, that moment is known as the crossover point.
When both projects have positive values, the crossover point is formed by the intersection of two IRR curves.
The weighted average cost of capital, also known as the crossover rate, is the rate of return at which the net present values (NPV) of two projects are equal.
The rate of return at which the net present value profiles of two projects cross each other is what this term denotes.
So, annual crossover sales are 1800 units.
Process emphasis is less expensive and less important for volumes under 1800 units; repeated manufacturing concentration is less expensive and less important for volumes exceeding 1800 units.
Fixed cost ÷ variable cost
$90000÷50 =$1800
$9,000÷5=$1800

what is the smallest Surface area for a 300-volume rectangular prism?
The minimum surface area of a rectangular prism with a volume of 300 units must lie somewhere between 0 and ∞.
Let's say that the rectangular prism has a length of "l" units, width of "w" units, and height of "h" units. The volume of the rectangular prism is given by the formula V = l × w × h, and we know that V = 300 units.
To find the smallest surface area possible, we need to minimize the sum of the areas of all six faces. The surface area (SA) of a rectangular prism is given by the formula SA = 2lw + 2lh + 2wh.
Using the formula for volume, we can solve for one of the variables in terms of the other two. For example, we can solve for "h" as follows:
V = l × w × h
300 = l × w × h
h = 300 / (l × w)
Substituting this expression for "h" into the formula for surface area, we get:
SA = 2lw + 2l(300 / lw) + 2w(300 / lw)
SA = 2lw + 600 / w + 600 / l
Now we need to find the minimum value of SA. To do this, we can take the derivative of SA with respect to either "l" or "w", set it equal to zero, and solve for the corresponding variable. Since the derivative is the same regardless of which variable we choose, we can take the derivative with respect to "l":
dSA/dl = 2w - 600 / l² = 0
l² = 300 / w
Substituting this expression for "l²" back into the formula for surface area, we get:
SA = 2lw + 600 / w + 600w / 300 / w
SA = 2lw + 600 / w + 2w²
Now we can take the derivative of SA with respect to "w" and set it equal to zero:
dSA/dw = 2l - 600 / w² + 4w = 0
w³ - 150lw + 150 = 0
Taking the limit as "w" approaches infinity, we get:
lim SA as w → ∞ = 2lw + 600 / ∞ + 2∞²
lim SA as w → ∞ = 2lw + 0 + ∞
This limit is also undefined, which means that there is no rectangular prism with a volume of 300 units and infinite surface area.
