Answer:
The equation of the perpendicular line is y=-3x-15.
Explanation:
Given the line y=1/3x+6
Comparing it with the slope-intercept form: y=mx+b
\(\text{Slope}=\frac{1}{3}\)Let the slope of the perpendicular line = m
Two lines are perpendicular if the product of their slopes is -1.
Therefore:
\(\begin{gathered} \frac{1}{3}m=-1 \\ m=-3 \end{gathered}\)To find the equation of the perpendicular line passing through (-9, 12), we use the point-slope form.
\(y-y_1=m(x-x_1)\)Substituting the slope and point (-9,12), we have:
\(\begin{gathered} y-12=-3(x-(-9)) \\ y-12=-3(x+9) \\ y-12=-3x-27 \\ y=-3x-27+12 \\ y=-3x-15 \end{gathered}\)The equation of the perpendicular line is y=-3x-15.

In given figure AB is the diameter of circle. If ∠CAD = 32° and ∠CPB = 28°. Find ∠CDA.
Answer:
Therefore, the angle ∠CDA is 58°.
Step-by-step explanation:
∠CDA = 58°
In the given figure, let's consider the angle ∠CDA as x.
Since AB is the diameter of the circle, we know that the angle subtended by any diameter at any point on the circumference is always 90°. Therefore, ∠CAB = 90°.
In triangle CAD, the sum of angles is 180°. So, we have:
∠CAD + ∠CDA + ∠CAB = 180°
Substituting the known values:
32° + x + 90° = 180°
Combining like terms:
x + 122° = 180°
Subtracting 122° from both sides:
x = 180° - 122°
x = 58°

Step-by-step explanation:
Differentiation is an algebraic process that finds the slope of a curve. At a point, the slope of a curve is the same as the slope of the tangent line to the curve at that point. Therefore, to find the slope of the line tangent to the given function, differentiate the given function.
Given function:
\(y=x^2\ln(2x)\)
Differentiate the given function using the product rule.
\(\boxed{\begin{minipage}{5.5 cm}\underline{Product Rule for Differentiation}\\\\If $y=uv$ then:\\\\$\dfrac{\text{d}y}{\text{d}x}=u\dfrac{\text{d}v}{\text{d}x}+v\dfrac{\text{d}u}{\text{d}x}$\\\end{minipage}}\)
\(\textsf{Let\;$u=x^2}\)\(\textsf{Let\;$u=x^2$}\implies \dfrac{\text{d}u}{\text{d}x}=2x\)
\(\textsf{Let\;$v=\ln(2x)$}\implies \dfrac{\text{d}v}{\text{d}x}=\dfrac{2}{2x}=\dfrac{1}{x}\)
Input the values into the product rule to differentiate the function:
\(\begin{aligned}\dfrac{\text{d}y}{\text{d}x}&=u\dfrac{\text{d}v}{\text{d}x}+v\dfrac{\text{d}u}{\text{d}x}\\\\&=x^2 \cdot \dfrac{1}{x}+\ln(2x) \cdot 2x\\\\&=x+2x\ln(2x)\end{aligned}\)
To find the slope of the tangent line at x = e²/2, substitute x = e²/2 into the differentiated function:
\(\begin{aligned}x=\dfrac{e^2}{2}\implies \dfrac{\text{d}y}{\text{d}x}&=\dfrac{e^2}{2}+2\left(\dfrac{e^2}{2}\right)\ln\left(2 \cdot \dfrac{e^2}{2}\right)\\\\&=\dfrac{e^2}{2}+e^2\ln\left(e^2\right)\\\\&=\dfrac{e^2}{2}+2e^2\\\\&=\dfrac{5e^2}{2}\end{aligned}\)
Therefore, the slope of the line tangent to the graph of y = x²ln(2x) at the point where x = e²/2 is:

What are the coordinates of the point on the directed line segment from ( − 10 , 9 ) (−10,9) to ( − 4 , 3 ) (−4,3) that partitions the segment into a ratio of 1 to 5 help plss
We can find the coordinates of the point that partitions a line segment into a ratio of 1 to 5 by using the formula:
(x, y) = (x1 + r * (x2 - x1), y1 + r * (y2 - y1))
Where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the line segment, and r is the ratio of the distance from the starting point to the point of interest, to the total distance of the line segment. In this case, r = 1/(1 + 5) = 1/6.
We know the coordinates of the two endpoints of the line segment:
(x1, y1) = (-10, 9)
(x2, y2) = (-4, 3)
So, we can substitute these values into the formula and find the coordinates of the point that partitions the line segment into a ratio of 1 to 5:
(x, y) = (-10 + (1/6) * ((-4) - (-10)), 9 + (1/6) * (3 - 9))
= (-10 + (1/6) * (-6), 9 + (1/6) * (-6))
= (-10 -1/6, 9 -1)
= (-10/6 -1/6, 3/2 -1)
= (-16/6, 3/2 -1)
= (-8/3,-1/2)
So, the coordinates of the point on the directed line segment from (-10, 9) to (-4, 3) that partitions the segment into a ratio of 1 to 5 is (-8/3,-1/2)
It is important to notice that this point is a vector and not a point in the Cartesian plane

The formulas for total revenue and total cost, in hundreds of dollars, for selling and producing q hundred Items are: total revenue: TR(q) = 30q total cost: Tc(q) = q^3-15q^2+75q+10. (a) Find the smallest quantity at which marginal cost is equal to 15 dollars per Item. (b) Recall: Fixed cost is given by FC = TC(0). Variable cost is given by VC(q) = TC(q) - FC. Average variable cost is given by AVC(q) = VC(q)/q. Find a positive value of q at which average variable cost is equal to marginal cost. (c) Find the longest interval on which marginal revenue exceeds marginal cost. (d) Recall that profit is given by P(q) = TR(q)-TC(q) and On an interval of quantities where MR(q) < MC(q), profit is decreasing. On an interval of quantities where MR(q) > MC(q), profit is increasing Use the sketch you drew in part (c) to find the quantity at which profit is greatest. What is the maximum value of profit?
(a). The smallest quantity at which marginal cost is equal to 15 dollars per item is 2.76. (b). The positive value of q at which average variable cost is equal to marginal cost is \(\frac{15}{2}\). (c). The longest interval on which marginal revenue exceeds marginal cost is (1.8377, 8.1622). (d). The profit is increasing at 8.1622 at p(q) is maximum. (e). The maximum value of profit is 78.2455 dollars.
The total revenue: TR(q) = 30q
The total cost: Tc(q) = \(q^3-15 q^2+75 q+10$\)
The change in cost is referred to as the change in the cost of production when there is a need for change in the volume of production.
(a). Marginal cost MC\(=\frac{\partial}{\partial q}(T C)$\)
\($$=3q^2-30 q+75 \text {. }$$\)
According to question.
\($$\begin{aligned}& 3 q^2-30 q+75=15 \\& 3 q^2-30 q+60=0 \\& q^2-10 q+20=0 \\& q= \frac{10 \pm \sqrt{100-80}}{2} \\&= \frac{10 \pm 2 \sqrt{5}}{2}=5 \pm \sqrt{5}\end{aligned}\)
\($$$\therefore \quad q=5+\sqrt{5} \quad$ and $q=5-\sqrt{5}$\)
we have to find smallest quantity.
\($$\therefore \quad q=5-\sqrt{5}=2.76 \text {. }$$\)
b)
\($$\begin{aligned}& F C=T C(0)=10 \\& V C(q)=T C(q)-F C \\& =q^3-15 q^2+75 q . \\& \text { AVC(q) }=\frac{V C(q)}{q}=q^2-15 q+75 .\end{aligned}$$\)
When AVC(q)=MC(q)
\($$\begin{array}{ll}\Rightarrow & q^2-15 q+7 ;=3 q^2-30 q+75 \\\Rightarrow & 2 q^2-15 q=0 .\ \Rightarrow q(2 q-15)=0 . \\\Rightarrow & q=0, \frac{15}{2} \quad \Rightarrow \quad q=\frac{15}{2}\end{array}$$\)
Therefore, the positive value of q at which average variable cost is equal to marginal cost is \(\frac{15}{2}\).
(c).
\(& M R(q)=\frac{d}{d q}(T R)=30 . \\\)
\(& M C(q)=3 q^2-30 q+75 . \\\)
Let MR(a)>MC(q)
\(& \Rightarrow \quad 30 > 3 q^2-30 q+75 \text {. } \\\)
\(& \Rightarrow \quad 3 q^2-3 p q+45 < 0 \\\)
\(& \Rightarrow \quad q^2-10 q+15 < 0 \text {. } \\\)
\(& \because \quad q=\frac{10 \pm \sqrt{100-60}}{2} \Rightarrow q=\frac{10 \pm 2 \sqrt{10}}{2} \\\)
\(& q=(5 \pm \sqrt{10}) \\\)
\(& \Rightarrow \quad(q-5+\sqrt{10})(q-5-\sqrt{10}) < 0 . \\\)
\(& \Rightarrow \(q-5+\sqrt{10}) < 0 \quad \& \quad(q-5-\sqrt{10}) > 0 \text {. } \\\)
\(& \text { or } \quad(q-5+\sqrt{10}) > 0 \quad \& \quad(q-5-\sqrt{10}) < 0 \text {. } \\\)
\(& \therefore \quad \text { other } q < 5-\sqrt{10}=1.8377 ., q > 5+\sqrt{10}=8.1622 \text {. } \\\)
\(& \Rightarrow \quad q < 1.8377 \& q > 0.1622 \text {. } \\\)
\(& \text { or } q > 5-\sqrt{10} \quad \& \quad q < 5+\sqrt{10} \text {. } \\\)
\(& \Rightarrow q > 1.8377 \quad < q < 8.1622 \text {. } \\\)
The Interval is (1.8377, 8.1622).
(d). P(q) =TR(q)-TC(q)
\(& =30 q-\left(q^3-15 q^2+75 q+10\right) \\& =-q^3+15 q^2-75 q-10+30 q \\& =-q^3+15 q^2-45 q-10 .\)
on (1.8377,8.1622). we have to find a point such that p"(q)=0 and p"(q)<0.
\(& p^{\prime}(q)=-3 q^2+30 q-45 \\\)
\(& \Rightarrow \quad-3\left(q^2-10 q+15\right)=0 \\\)
\(& \Rightarrow \quad q^2-10 q+15=0 . \\\)
\(& \quad q=1.8377 \text { and } \quad q=8.1622 . \\\)
\(& \Rightarrow \quad p^{\prime \prime}(q)=-6 q+30 . \\\)
\(& p^{\prime \prime}(1.8377)=-6(1.8377)+30 \\\)
\(&=18.9738 \\\)
\(& p^{\prime \prime}(8.1622)=-6(8.1622)+30 . &=-18.9732 < 0 .\)
at 8.1622, p(q) is maximum.

Step-by-step explanation:
According to a government report, the aging of the U.S. population is translating into many more visits to doctors’ offices and hospitals. It is estimated that an average person makes four visits a year to doctors’ offices and hospitals. (i) What are the mean and the standard deviation of an average person’s number of monthly visits to doctors’ offices and hospitals? (ii) What is the probability that an average person does not make any monthly visits to doctors’ offices and hospitals? (iii) What is the probability that an average person makes at least one monthly visit to doctors’ offices and hospitals?
Following the Poisson distribution we get values, (i) Mean and standard deviation of monthly visits: mean = 1/3, standard deviation = sqrt(1/3). (ii) Probability of no visits: 0.7165 and (iii) Probability of at least one visit: 0.2835.
To answer the questions, we need to make some assumptions and calculations based on the given information. Let's proceed step by step:
(i) Mean and Standard Deviation:
Given that an average person makes four visits a year to doctors' offices and hospitals, we can calculate the average number of monthly visits by dividing the yearly visits by 12 months:
Average monthly visits = (4 visits/year) / 12 months = 1/3 visits/month
Since the average number of monthly visits is 1/3, the mean is also 1/3.
To calculate the standard deviation, we need to consider the variability in the number of visits. Since the number of visits is discrete and follows a Poisson distribution, the standard deviation is equal to the square root of the mean:
Standard deviation = sqrt(mean) = sqrt(1/3)
(ii) Probability of not making any monthly visits:
To calculate the probability that an average person does not make any monthly visits, we need to use the Poisson distribution formula. In this case, the average number of monthly visits (λ) is 1/3. The probability of not making any monthly visits (P(x = 0)) is given by:
P(x = 0) = (e(-λ) * λ⁰) / 0!
Substituting the value of λ = 1/3:
\(P(x = 0) = (e^(-1/3) * (1/3)^0) / 0!\\P(x = 0) = e^(-1/3) = 0.7165\)
Therefore, the probability that an average person does not make any monthly visits to doctors' offices and hospitals is approximately 0.7165.
(iii) Probability of making at least one monthly visit:
To calculate the probability that an average person makes at least one monthly visit, we can subtract the probability of not making any visits from 1:
P(x ≥ 1) = 1 - P(x = 0)
Substituting the previously calculated value of P(x = 0):
P(x ≥ 1) = 1 - 0.7165
P(x ≥ 1) ≈ 0.2835
Therefore, the probability that an average person makes at least one monthly visit to doctors' offices and hospitals is approximately 0.2835.

The major rule for solving the above is called the Sine and Cosine rules.
The Sine Rule, also known as the Law of Sines, relates the sides and angles of a triangle. The Cosine Rule, also known as the Law of Cosines, relates the sides and angles of a triangle by using the cosine function.
Let us look an example for each.
10) where a=9, b = 7, A = 108°
Using the Law of Sines:
a/sin(A) = b/sin(B) = c/sin(C)
Substituting the given values:
9/sin(108°) = 7/sin(B)
Solving for sin(B):
sin(B) = 7*sin(108°)/9
Using the fact that the sum of the angles in a triangle is 180°, we have:
C = 180° - A - B
Substituting the given values and the value of sin(B) we just found:
C = 180° - 108° - sin⁻¹(7*sin(108°)/9)
Simplifying:
C ≈ 25.56°
Finally, using the Law of Sines again to find the length of side c:
c/sin(C) = a/sin(A)
Substituting the given values:
c/sin(25.56°) = 9/sin(108°)
Solving for c:
c ≈ 12.31
Therefore, the sides of the triangle are a = 9, b = 7, and c ≈ 12.31, and the angles are A = 108°, B ≈ 46.44°, and C ≈ 25.56°.
11) here we are given: a = 14, b = 15, A = 117°
Using the Law of Cosines:
c² = a² + b² - 2ab*cos(C)
Substituting the given values:
c² = 14² + 15² - 2(14)(15)*cos(C)
Simplifying:
c² = 601 - 420*cos(C)
Using the fact that the sum of the angles in a triangle is 180°, we have:
C = 180° - A - B
Substituting the given value of A and using the fact that a = 14 and b = 15:
cos(B) = (a² + c² - b²)/(2ac)
cos(B) = (14² + c² - 15²)/(214c)
cos(B) = (196 + c² - 225)/(28c)
cos(B) = (c² - 29)/28c
Substituting the value of cos(B) into the equation for C:
cos(C) = cos(180° - A - B)
cos(C) = -cos(A + B)
cos(C) = -cos(A)*cos(B) + sin(A)*sin(B)
Substituting the given values and the value of cos(B) we just found:
cos(C) = -cos(117°)*((c² - 29)/(28c)) + sin(117°)*√(1 - ((c² - 29)/(28c))²)
Simplifying:
cos(C) = -(cos(117°)/28) + (sin(117°)/28)*√(784c² - 4c⁴ - 784)/c
Solving for c using a numerical method, we find that:
c ≈ 19.23
Therefore, the sides of the triangle are a = 14, b = 15, and c ≈ 19.23, and the angles are A = 117°, B ≈ 23.7°, and C ≈ 39.3°.
17) here we are given: a = 10, b =√200, A = 45°
First, we can simplify √200 by factoring out the perfect square 100 from under the square root sign:
√200 = √(100*2) = √100 * √2 = 10√2
Using the Law of Sines:
a/sin(A) = b/sin(B) = c/sin(C)
Substituting the given values:
10/sin(45°) = 10√2/sin(B)
Solving for sin(B):
sin(B) = sin(45°) / √2 = √2/2
Using the fact that the sum of the angles in a triangle is 180°, we have:
C = 180° - A - B
Substituting the given values and the value of sin(B) we just found:
C ≈ 90° - 45° = 45°
Finally, using the Law of Sines again to find the length of side c:
c/sin(C) = a/sin(A)
Substituting the given values:
c/sin(45°) = 10/sin(45°)
Solving for c:
c = 10
Therefore, the sides of the triangle are a = 10, b = 10√2, and c = 10, and the angles are A = 45°, B ≈ 45°, and C ≈ 90°.

Get it right please.
A zoologist recorded the speed of two cheetahs. Cheetah A ran 17 miles in 8 minutes. Cheetah B ran 56 miles in 20 minutes. Which statement is correct?
Cheetah A has a higher ratio of miles per minute than Cheetah B because 17 over 8 is less than 56 over 20.
Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is greater than 56 over 20.
Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is less than 56 over 20.
Both cheetahs have the same ratio of miles per minute.
The answer would be C - "Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is less than 56 over 20."

Step-by-step explanation:
You will create an estimate in order to assist your boss in gaining the job!
The equation that is given by the customer for the pool is (units are in feet): x2 + y2 = 81
- Your performance needs to include the following calculations:
- Compute the radius and diameter of the pool.
- Compute the volume of water in the pool using the above calculations and a height of 4 ft.
- Assuming that water costs $0.22 per gallon and that pools cost $185 per foot of radius calculate the total cost of materials for the pool. Keep in mind that there are 7.48 gallons of water per square foot.
- Assuming that a pool will take 2.5 hrs. per foot of radius, compute the total labor hours for the pool.
- If you are to pay someone $19/hr, compute the total cost of labor.
- Find a total cost for the project.
- All of the above is done showing all work.
- A final paragraph that describes your steps and findings.
The solution has been explained below.
We will use the following equation, x² + y² = 81, where x and y are the pool's dimensions in feet, to determine the necessary estimations for the pool project.
1. Calculate the pool's diameter and radius:
We can infer that the radius of the pool is equal to the square root of 81 because the equation depicts a circle. As a result, r = 81 = 9 ft.
The pool's diameter is simply equal to twice its radius, or d = 2r = 18 feet.
2. Calculate the amount of water in the pool:
Since the pool is 4 feet high, we can determine its volume by multiplying the area of its circle-shaped base by the height.
The formula A = πr² can be used to calculate the area of the pool's base,
Therefore, V = Ah = πr²h = 1017.87 cubic feet represents the volume of water in the pool.
3. Determine the pool's total material cost:
There are 7.48 gallons in a cubic foot and a gallon of water costs $0.22.
As a result, Cw = V × 7.48 × 0.22 = 1017.87 × 7.48 × 0.22 = $1,619.72 is the entire cost of water for the pool.
If the radius of the pool is $185 per foot, then the cost of the materials is Cm = r × 185 = 9 × 185 = $1,665.
4. Calculate the pool's total labour hours:
A pool's construction is estimated to take 2.5 hours for every foot of its radius.
So, L = r × 2.5 = 9 × 2.5 = 22.5 hours of labour would be needed to complete this pool.
5. Calculate the total cost of labour for the project:
If you pay someone $19 per hour, Cl = L × 19 = 22.5 × 19 = $427.5.
6. Find the project's overall cost:
The project's overall cost is the product of its labour and material costs:
Cost as a whole equals Cm + Cw + Cl, which is 1,665 + 1,619.72 + 427.5, or $3,712.22.
In conclusion, the pool has an 18-foot diameter and a 9-foot radius according to the supplied equation. There are roughly 1017.87 cubic feet of water in the pool. Water and building supplies are included in the pool's projected material cost of $3,284.72. 22.5 hours of labour in total are needed, with a labour cost estimate of $427.5. Consequently, $3,712.22 is the expected final cost of the pool renovation.
