For each of the following find:
I. lim f (x) as x approaches a from the negative
II. lim f (x) as x approaches a from the positive
III. lim f (x) as x approaches a
a. f(x)={ sin x/3, if x< or equal to pi a=pi
{ x(root3)/(2pi), if x>pi
b. f(x)= (x^2-36)/root(x^2-12x+36) a=6
Answer:
a. For the function:
f(x) = { sin x/3, if x ≤ π
{ x√3/2π, if x > π
I. To find lim f(x) as x approaches π from the negative side, we need to evaluate f(x) for values of x that are slightly less than π. In this case, since sin(x/3) is a continuous function, we can simply evaluate it at x = π:
lim f(x) as x approaches π- = f(π-) = sin(π/3) = √3/2
II. To find lim f(x) as x approaches π from the positive side, we need to evaluate f(x) for values of x that are slightly greater than π. In this case, we can simply evaluate the other part of the piecewise function at x = π:
lim f(x) as x approaches π+ = f(π+) = π√3/2π = √3/2
III. To find lim f(x) as x approaches π, we need to check whether the left-hand and right-hand limits are equal. In this case, since both the left- and right-hand limits exist and are equal, we have:
lim f(x) as x approaches π = √3/2
b. For the function:
f(x) = (x^2 - 36)/√(x^2 - 12x + 36)
I. To find lim f(x) as x approaches 6 from the negative side, we need to evaluate f(x) for values of x that are slightly less than 6. In this case, we can substitute x = 6 - h, where h is a positive number approaching zero, to get:
lim f(x) as x approaches 6- = lim f(6 - h) as h approaches 0
Substituting x = 6 - h into the function, we get:
f(6 - h) = [(6 - h)^2 - 36]/√[(6 - h)^2 - 12(6 - h) + 36]
= [h^2 - 12h]/√[h^2]
Simplifying the numerator and denominator separately, we get:
f(6 - h) = h(h - 12)/|h|
Since h approaches 0 from the positive side, we have:
lim f(6 - h) as h approaches 0+ = lim h(h - 12)/h as h approaches 0+ = lim (h - 12) as h approaches 0+ = -12
II. To find lim f(x) as x approaches 6 from the positive side, we need to evaluate f(x) for values of x that are slightly greater than 6. In this case, we can substitute x = 6 + h, where h is a positive number approaching zero, to get:
lim f(x) as x approaches 6+ = lim f(6 + h) as h approaches 0
Substituting x = 6 + h into the function, we get:
f(6 + h) = [(6 + h)^2 - 36]/√[(6 + h)^2 - 12(6 + h) + 36]
= [h^2 + 12h]/√[h^2]
Simplifying the numerator and denominator separately, we get:
f(6 + h) = h(h + 12)/|h|
Since h approaches 0 from the positive side, we have:
lim f(6 + h) as h approaches 0+ = lim h(h +

A rectangular garden is to be constructed using a rock wall as one side of the garden and wire fencing for the other three sides. Given that there are 30 meters of fencing available, determine the dimensions that would create the garden of maximum area. What is the maximum possible area?
The dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is 75 square meters
What is measurement?
Measurement is the process of assigning numerical values to physical quantities, such as length, mass, time, temperature, and volume, in order to describe and quantify the properties of objects and phenomena.
Let's assume that the rock wall is the width of the garden and the wire fencing is used for the length and the other two sides. Let's denote the length of the garden as L and the width as W.
Since we have 30 meters of fencing available, the total length of wire fencing used is:
L + 2W = 30 - W
Simplifying this equation, we get:
L = 30 - 3W
The area of the garden is:
A = LW
Substituting the expression for L from the previous equation, we get:
A = W(30 - 3W)
Expanding the expression, we get:
A = 30W - 3W²
To find the maximum area, we need to take the derivative of A with respect to W and set it equal to zero:
dA/dW = 30 - 6W = 0
Solving for W, we get:
W = 5
Substituting this value back into the expression for L, we get:
L = 15
Therefore, the dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is:
A = 5(15) = 75 square meters

Answer:
C. RP = 4.5
Step-by-step explanation:
You want to know what condition is sufficient to show ∆ABC ~ ∆QPR, given three sides and 2 angles in ∆ABC, and 2 sides in ∆QPR.
SimilaritySimilarity can be shown if all three sides are proportional, or if two angles are congruent.
The offered answer choices only list one angle, so none of those will work. The answer choice that makes the third side of ∆QPR be in the same proportion as the corresponding side of ∆ABC is the condition of interest.
C. RP = 4.5

Additional comment
The side ratios in the two triangles are ...
AB : BC : CA = 10 : 9 : 6
QP : PR : RQ = 5 : PR : 3
For these ratios to be the same, PR must be half of BC, just as the other segments in ∆QPR are half their counterparts in ∆ABC.
Things did not go quite as planned. You invested $21360, part of it in a stock that paid 12% annual interest. However, the rest of the money suffered a 5% loss. If the total annual income from both investments was $, how much was invested at each rate? How much money was invested at 12% annual interest?
Answer:
1992
Step-by-step explanation:
Let x be the amount invested at 12%.
Then the rest amount is (21360-x) dollars.
The 12% stock earning is 0.12x dollars.
The rest amount loss is 0.05*(21360-x) dollars.
Your equation is
interest - loss = total interest, or
0.12x - 0.05*(21360-x) = 1992 dollars.

There are two temples, one on each bank of a river, just opposite to each other. One is 54m high. From the top of this temple angle of depression of the top and foot of the other temple are 30⁰ and 60°. Find width of river and height of other temple.
for your help its question of class 10 height and distances.
Answer:
height temple (other bank) = 54
Width of river = 31.177
Step-by-step explanation:
What you get is something that resembles a rectangle. That's because the two angles of depression add to 90 degrees. Therefore from the top of the given temple to the one across the river add up to 90 and the temples are both perpendicular to the ground.
So the other temple is 54 m high as well.
Now for the width of the river. The width of the river is the opposite side making up the tan(30) degree angle.
Formula
Tan(30) = river width/ height of first temple.
Tan(30) = river width / 54 m
Tan(30) = 0.5774
0.5774= river width / 54 Multiply both sides by 54
0.5774*54 = river width
river width = 31.177
Suppose that the dollar cost of producing x appliances is c(x)=800+70x-0.3x^2.
a. Find the average cost per appliance of producing the first 80 appliances.
b. Find the marginal cost when 80 appliances are produced.
c. Show that the marginal cost when 80 appliances are produced is approximately the cost of producing one more appliance after the first 80 have been made, by calculating the latter cost directly.
Answer:
To answer the questions, let's analyze the given cost function:
c(x) = 800 + 70x - 0.3x^2
a. To find the average cost per appliance of producing the first 80 appliances, we divide the total cost of producing 80 appliances by 80:
Average cost = c(80) / 80
Substituting x = 80 into the cost function:
Average cost = (800 + 70(80) - 0.3(80)^2) / 80
Calculating this expression will give us the average cost per appliance.
b. The marginal cost represents the change in cost when one additional unit is produced. To find the marginal cost when 80 appliances are produced, we need to calculate the derivative of the cost function with respect to x:
c'(x) = 70 - 0.6x
Substituting x = 80 into the derivative:
Marginal cost = c'(80) = 70 - 0.6(80)
This will give us the marginal cost at 80 appliances.
c. To show that the marginal cost when 80 appliances are produced is approximately the cost of producing one more appliance after the first 80 have been made, we can calculate the cost of producing 81 appliances and compare it with the marginal cost at 80 appliances.
To calculate the cost of producing 81 appliances directly, we substitute x = 81 into the cost function:
Cost of producing 81 appliances = c(81) = 800 + 70(81) - 0.3(81)^2
By comparing this cost with the marginal cost at 80 appliances, we can observe if they are approximately equal.
Please let me know if you would like me to perform the calculations or if there's anything else I can assist you with.

Kenneth is creating a chart to compare and contrast the different transformations of objects. He wants to show similarities and differences between translations, rotations, and reflections. In his chart, four statements are given. Which statements are true for a translation? Group of answer choices The distances between points on the polygon are preserved by the transformation. The orientation of points on the polygon is preserved by the transformation. The distance between corresponding points in the image and pre-image is constant. The angle measures between sides on the polygon are preserved by the transformation.
The statements that are true for a translation are:
The distances between points on the polygon are preserved by the transformation.
The distance between corresponding points in the image and pre-image is constant.
These statements are true for a translation because when an object is translated, it is shifted a certain distance in a certain direction. This means that the distances between points on the polygon remain the same and the distance between the corresponding points in the image and pre-image is constant.
Translation is the process of converting written, spoken, or visual information from one language into another. It is a complex process involving both linguistic knowledge and cultural understanding. Professional translators use a range of techniques to accurately convey the meaning of a text, including knowledge of grammar, syntax, and idiomatic expressions. Translators also take into account the cultural context of the text, ensuring that the translation reflects the same cultural references and nuances as the original. Translation can also refer to the conversion of DNA sequences from one form to another, such as from RNA to protein.

A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 8 m and a diameter of 10 m. The container will be made from steel (including its top and bottom). Suppose the total cost of the steel will be $13,062.40. How much will the steel cost per square meter? Use 3.14 for it, and do not round your answer.
The per square meter cost of steel will be $32. The solution has been obtained by using the cylinder.
What is a cylinder?
The cylinder, one of the most basic curvilinear geometric shapes, has long been considered to be a three-dimensional solid. It is regarded as a prism with a circle as its basis in elementary geometry.
We are given that the height of cylinder is 8 m and diameter is 10 m.
So, the radius is 5 m.
Now, using the surface area formula, we get
⇒ S = 2πrh + 2π\(r^{2}\)
⇒ S = 2π * 5 * 8 + 2π * \(5^{2}\)
⇒ S = 2 * 3.14 * 5 * 8 + 2 * 3.14 * 25
⇒ S = 251.2 + 157
⇒ S = 408.2 square meter
Now, it is given that the total cost of the steel will be $13,062.40.
So, per square meter cost will be:
⇒ Cost = \(\frac{13,062.40}{408.2\\}\)
⇒ Cost = $32
Hence, the per square meter cost of steel for the cylinder will be $32.

Solving a system of equations we can see that:
She needs to use 56 oz of the 85% solution.She needs to use 14 oz of the 60% solution.How many ounces of each solution should she use?We can use the variables:
x = mass of the 60% solution.
y = mass of the 85% solution.
We can write a system of equations.
x + y = 70
x*0.6 + y*0.85 = 70*0.8
We can isolate x on the first equation to get:
x = 70 - y
Replace that in the other one:
(70 - y)*0.6 + y*0.85 = 70*0.8

different equation dy÷dx+ytanx=secx
Answer:
First, we rearrange the equation to isolate the y-term on one side:
dy/dx + ytanx = secx
Then, we multiply both sides by the integrating factor, which is e^(∫tanx dx) = e^(ln|secx|) = |secx|: | secx| dy/dx + ysecx tanx = 1
Next, we can write this as the derivative of a product using the product rule: d/dx (y |secx|) = 1
Integrating both sides with respect to x, we get: y |secx| = x + C
where C is the constant of integration. Solving for y, we have:
y = (x + C)/|secx|
Note that there is a singularity at x = (2n + 1)π/2, where the denominator |secx| is zero. At these points, the solution is not defined
A circle is centered at the origin and contains the point (-4, -3). What is the area of this circle?
The circle has center at teh origin ( 0,0) and a passing point ( -4, -3)
The general equation of circle is :
\(\begin{gathered} (x-a)^2+(y-b)^2=r^2 \\ \text{where, (a,b) are the center of the circle} \end{gathered}\)In the given question the center : ( 0,0)
So,
\(\begin{gathered} (x-a)^2+(y-b)^2=r^2 \\ (x-0)^2+(y-0)^2=r^2 \\ x^2+y^2=r^2 \end{gathered}\)Since, the circle passes through ( -4, -3) so put x = -4 and y =-3 ans solve for r
\(\begin{gathered} x^2+y^2=r^2 \\ (-4)^2+(-3)^2=r^2 \\ 16+9=r^2 \\ r^2=25 \\ r=\sqrt[]{25} \\ r=5 \end{gathered}\)Thus radius = 5
Equation of circle is :
\(\begin{gathered} \mleft(x-0\mright)^2+\mleft(y-0\mright)^2=5^2^{} \\ x^2+y^2=25 \end{gathered}\)The general expression for the area pf circle is :
\(\text{Area of circle = }\Pi(radius)^2\)Substitute the value of radius = 5
\(\begin{gathered} \text{Area of circle = }\Pi(radius)^2 \\ \text{Area of circle = }\Pi5^2 \\ \text{Area of Circle = 25 }\times3.14 \\ \text{Area of Circle = 78.5 unit}^{2} \end{gathered}\)So, Area of circle is 78.5 unit²

After training Naruto went to a ramen shop for dinner. Since Naruto eats ramen for lunch and dinner daily, the shopkeeper gives him a 33.33% discount. If ramen costs 45 cents, how much does Naruto spend in 15 days?
Points given: 20
To calculate how much Naruto spends on ramen in 15 days, we need to determine the total cost of ramen per day and then multiply it by 15.
Since Naruto receives a 33.33% discount, he pays 100% - 33.33% = 66.67% of the original price.
66.67% of 45 cents is (66.67/100) * 45 = 30 cents.
So, Naruto spends 30 cents on ramen per day.
To find out how much he spends in 15 days, we multiply the daily cost by the number of days:
30 cents * 15 = 450 cents.
Therefore, Naruto spends 450 cents, which is equivalent to $4.50, on ramen in 15 days.
