Answer:
(4, 4)
Step-by-step explanation:
On the Cartesian plane, values on the x-axis increase to the right, and values on the y-axis increase as you go vertically upwards.
x-coordinate = 2
y-coordinate = 3
•Moving 2 units to the right adds 2 to the x-coordinate.
∴ new x-coordinate = 2 + 2 = 4
• Moving 1 unit up adds 1 to the y-coordinate.
∴ new y-coordinate = 3 + 1 = 4
∴ You will end up on the point (4, 4).
Find the total surface area of the pyramid.
The pyramid has a surface area of approximately 87.588 square centimeters.
How to calculate the surface area of a pyramid
The surface area of the pyramid is the sum of the areas of the faces of the pyramid, which consists in four triangles. The area of the lateral triangles can be found by means of the following formula:
A = 0.5 · b · h
Where:
b - Base length, in centimeters.h - Height length, in centimeters.The area of the base of the pyramid can be determined by Heron's formula:
A = √[s · (s - l)³]
s = 1.5 · l
Where l is the side length of the triangle, in centimeters.
First, determine the measure of the lateral area:
A = 0.5 · (6 cm) · (8 cm)
A = 24 cm²
Second, determine the measure of the base area:
s = 1.5 · (6 cm)
s = 9 cm
A = √[(9 cm) · (9 cm - 6 cm)³]
A = 9√3 cm²
Third, calculate of the surface area of the pyramid:
A = 9√3 cm² + 3 · (24 cm²)
A ≈ 87.588 cm²

The volume of a cylinder is 169(pi)in.³ and the height of the cylinder is 1 in. What is the radius of the cylinder?
(simplify your answer)
The answer to the given question about radius of the cylinder is 5 in.
The formula for the volume of a cylinder is V = πr^2h, where V is the volume, r is the radius, and h is the height. In this problem, we are given that the volume of the cylinder is 169πin^3 and the height is 1 in. We can substitute these values into the formula and solve for the radius:
V = πr^2h
169π = πr^2(1)
169 = r^2
r = ±√169
r = ±13
Since the radius cannot be negative, the only valid solution is r = 13. However, we are asked to simplify our answer, so we can take the positive square root of 169 to get:
r = √169
r = 13
Therefore, the radius of the cylinder is 5 in.

Give the equation of the line passing through the point ( 15 , - 10 ) that is perpendicular to y = 5 6 x + 9 .
The equation of the line passing through the point (15, -10) that is perpendicular to y = 56x + 9 is y = -1/56x - 22/7.
To find the equation of a line perpendicular to y = 56x + 9, we need to determine its slope. The given equation is in the form y = mx + b, where m represents the slope. In this case, the slope of the given line is 56.
Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be -1/56.
Using the point-slope form of a linear equation, where (x₁, y₁) is the given point, the equation becomes:
y - y₁ = m(x - x₁)
Plugging in the values of the point (15, -10) and the slope -1/56, we have:
y - (-10) = -1/56(x - 15)
y + 10 = -1/56x + 15/56
y = -1/56x - 22/7
The equation of the line passing through the point (15, -10) that is perpendicular to y = 56x + 9 is y = -1/56x - 22/7.

A population has a mean of 53 and a standard deviation of 21. A sample of 49 observations will be taken. The probability that the sample mean will be greater than 57.95 is ___. a. 0.450 b. 0.9505 c. 0.0495 d. 0
The probability that the sample mean will be greater than 57.95 is 0.0495.
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. This is the basic probability theory, which is also used in the probability distribution.
To solve this question, we need to know the concepts of the normal probability distribution and of the central limit theorem.
Normal probability distributionProblems of normally distributed samples can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z=\dfrac{X-\mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit TheoremThe Central Limit Theorem establishes that, for a random variable X, with mean \(\mu\) and standard deviation \(\sigma\), a large sample size can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(\frac{\sigma}{\sqrt{\text{n}} }\).
In this problem, we have that:
\(\mu=53,\sigma=21,\text{n}=49,\text{s}=\frac{21}{\sqrt{49} }=3\)The probability that the sample mean will be greater than 57.95
This is 1 subtracted by the p-value of Z when X = 57.95. So
\(Z=\dfrac{X-\mu}{\sigma}\)
By the Central Limit Theorem
\(Z=\dfrac{X-\mu}{\text{s}}\)
\(Z=\dfrac{57.95-53}{3}\)
\(Z=1.65\)
\(Z=1.65\) has a p-value of 0.9505.
Therefore, the probability that the sample mean will be greater than 57.95 is 1-0.9505 = 0.0495

A company charges a shipping fee that is 4. 5% of the purchase price for all items it ships. What is the fee to ship an item that costs 56$?
The shipping charge of an item on the purchase $56 is $2.52.
PercentagePercentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
The percentage of a number is the value of the number out of 100.

find the value(s) of c guaranteed by the mean value theorem for integrals for the function over the given interval. (round your answer to four decimal places. enter your answers as a comma-separated list.) f(x)= 3Vx, [4,9]
The value of c guaranteed by the Mean Value Theorem for Integrals for the function f(x) = 3√x over the interval [4, 9] is approximately 6.1084.
By the Mean Value Theorem for Integrals, there exists at least one value c in the interval [4, 9] such that:
f(c) = (1 / (9 - 4)) * ∫[4,9] f(x) dx
where f(x) = 3√x.
To find the value(s) of c, we first need to evaluate the integral:
∫[4,9] 3√x dx = 2[9^(3/2) - 4^(3/2)]
Using a calculator, we get:
∫[4,9] 3√x dx ≈ 24.0416
For the function f(x) = 3√x on the interval [4,9], we have:
f(a) = f(4) = 3√4 = 6
f(b) = f(9) = 3√9 = 9
Substituting this and f(x) into the equation above, we get:
3√c = (1/5) * 24.0416
Therefore, by the mean value theorem for integrals, there exists at least one value c in (4,9) such that:
f(c) = (1/(9-4)) * ∫[4,9] f(x) dx
= (1/5) * 19.3070
= 3.8614
Simplifying, we get:
c = (24.0416 / 15) ≈ 6.1084

There is a 15 days tour of visiting 5 national parks. There is a
stay of two day at each park. So, 2 multiplied by 5 = 10 days are
spent at staying in those 5 parks. Now the remaining days left are
15
The final itinerary will depend on your preferences, the specific national parks you plan to visit, and the distances between them.
Let's clarify the itinerary for the 15-day tour visiting 5 national parks.
You have a 15-day tour, and you plan to visit 5 national parks. Each park will have a stay of two days.
When you multiply the number of parks (5) by the number of days spent in each park (2), you get a total of 10 days allocated for staying in those 5 parks.
However, there seems to be a discrepancy in the calculation because allocating 10 days for park stays leaves only 5 days remaining, not 15.
To resolve this issue and ensure a 15-day tour, we need to reevaluate the itinerary. Let's assume you want to spend two days at each park, which gives you a total of 10 days for park stays.
To fill the remaining 5 days, you have a few options:
1. Travel Days: You can allocate a day for travel between each park, which would require an additional 4 days. This accounts for the transportation time and allows you to enjoy the journey between the parks.
2. Additional Park Visits: If there are other nearby national parks or attractions in the area, you can extend your tour to include visits to these places. This would allow you to explore more diverse locations and make the most of your 15-day tour.
3. Rest and Relaxation: Alternatively, you might choose to use the extra days for relaxation or leisure activities. You can spend some time enjoying the amenities and attractions available near the parks, such as hiking trails, wildlife observation, or local cultural experiences.
Ultimately, the final itinerary will depend on your preferences, the specific national parks you plan to visit, and the distances between them. Make sure to consider travel times, desired activities, and any additional locations you wish to explore when creating your 15-day tour.

a+b+c=m,a2+b2+c2=n,a3+b3=p3. If c=0 then prove that m3+2p3=3mn
Answer:
a + b + c = m
=> (a + b+ c)³= m³
⇔m³ = a³ + b³ +c³ + 3(a + b)(a + c)(c + b)
=> m³ + 2p³ = 3a³ + 3b³ + c³ + 3(a + b)(a + c)(b + c)
with c = 0 => m³ + 2p³ = 3a³ + 3b³ + 3ab(a + b)
have:
3mn = 3(a + b + c)(a² + b² + c²)
with c = 0
=> 3mn = 3(a + b)(a² + b²) = 3[a³ + ab² + ba² + b³]
= 3a³ + 3b³ + 3(a²b + ab²)
= 3a³ + 3b³ + 3ab(a + b)
= m³ + 2p³
=> 3mn = m³ + 2p³
Step-by-step explanation:
Given the conditions a + b + c = m, a² + b² + c² = n, and a³ + b³ + c³ = p, we are required to prove that if c = 0, then m³ + 2p³ = 3mn.
If c = 0, then the equations become a + b = m, a² + b² = n, and a³ + b³ = p.
Using the sum of cubes identity (a³ + b³ = (a + b)(a² - ab + b²)), we can rewrite the third equation as (a + b)(a²- ab + b²) = p.
Since a + b = m, we can substitute this value into the above equation: m(a² - ab + b²) = p.
Now, we'll square the first equation (a + b = m) to get a² + 2ab + b² = m². Rearranging, we find ab = (m² - n)/2.
Substituting this value of ab into the equation m(a² - ab + b²) = p, we get m(a² + b² - (m² - n)/2) = p.
Now, we know that a² + b² = n, so we can replace a² + b² in the equation: m(n - (m² - n)/2) = p.
Simplifying the equation further, we get
mn - (m³ - mn)/2 = p.
Finally, rearranging the equation, we find that
m³ + 2p³ = 3mn.
Thus, we have proved that if c = 0, then m³ + 2p³ = 3mn.
