The area of a cone is
\(\pi \times r {}^{2} + \pi \times r \times \sqrt{ {r }^{2} + {h}^{2} } \)
The volume of the conical paper cup will be option (D) 24π
What is Cone?A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the vertex.A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the vertex, to all of the points on a base that is in a plane that does not contain the vertex.Cone is a solid or hollow object which tapers from a circular or roughly circular base to a point.What are steps to solve this problem?The steps are as follow:
Given:r = base radius = 3 cm
h = height of cone = 8 cm
V = volume of cone = (1/3)πr²h.
V = (1/3)π*3²*8.
V = 24π
So, the volume of the conical paper cup will be option (D) 24π

On a bicycle, Jordan rides for 2 hours and is 20 miles from her house. After riding for 4 hours, she is 38 miles away. What is Jordan's average rate over the last 2 hours of her trip
Jordan's average rate over the last 2 hours of her trip is 9 miles/hour.
To find Jordan's average rate over the last 2 hours of her trip,
we need to calculate the distance she traveled during that time period.
We know that Jordan was initially 20 miles away from her house and after 4 hours, she was 38 miles away. Therefore, she traveled a distance of 38 miles - 20 miles = 18 miles in the first 4 hours.
To find her average rate over the last 2 hours, we divide the distance traveled in those 2 hours by the time taken. The distance traveled in the last 2 hours is 18 miles (since she traveled 18 miles in the first 4 hours), and the time taken is 2 hours.
Average rate = Distance / Time
Average rate = 18 miles / 2 hours
Average rate = 9 miles per hour

The matrix exponential eAt can be expressed as:
eAt = (5/4)*e^(3t/2) * [1 3/5; 2/5 1]
Sketching the phase plane, we can see that it represents a spiral source. The solution X(t) satisfying X(0) = [-2] can be found by substituting
t=0 and X(0) = [-2] in the general solution as follows:
X(t) = e^(3t/2) * [1 3/5; 2/5 1] * [-2]X(t) = [-2e^(3t/2)*(3/5) + 2e^(3t/2); -4e^(3t/2)/5 + 2e^(3t/2)]
Hence, the solution X(t) satisfying
X(0) = [-2] is X(t) = [-2e^(3t/2)*(3/5) + 2e^(3t/2); -4e^(3t/2)/5 + 2e^(3t/2)].

We need to find the general solution, sketch the phase plane and determine its type.The general solution is given by: X(t)

Where eAt is the matrix exponential. Since A is a 2x2 matrix, we can find eAt by using the formula:

A prism has a trapezoid as its base whose area is 140 square centimeters. A cylinder with the same height has a radius of 6 centimeters. How much larger, to the nearest cubic centimeter, is the volume of the prism than the volume of the cylinder?
Answer:
difference in volume = 26.96h cm³
Step-by-step explanation:
The volume of a prism is the product of the base area and the height. A trapezoid prism has a trapezium as the base shape. Therefore,
volume of a trapezoid prism = area of a trapezium × height
area of the base(trapezoid) = 140 cm²
Volume = 140h
Volume of a cylinder = πr²h
where
r = radius
h = height
volume = πr²h
volume = π × 6² × h
volume = 3.14 × 36 × h
volume = 113.04h
To know how much larger the volume of the prism is than the volume of the cylinder we have to take the difference of the volume.
Recall the height are the same
difference in volume = 140h - 113.04h
difference in volume = 26.96h cm³
If 5 is an element in the domain of , what is the corresponding element in the range?
Answer:
13/4
Step-by-step explanation:
\(f(x) = \frac{7x - 22}{4} \)
\(f(5) = \frac{7(5) - 22}{4} = \frac{35 - 22}{4} = \frac{13}{4} \)
The functions f(x) = x2 – 2 and g(x) = –x2 + 5 are shown on the graph.
There are two stiff transforms to use:
Vertical movement 7 units to the plus side.reflection along the y = 5 line.The fact that the real domain is the domain of quadratic functions makes it possible to identify the solution set.
How can rigid transformations be used?Thus, we must decide which rigid transformations to apply to f(x) in order to produce g(x). Rigid transformations are transformations applied to geometric loci in the field of Euclidean geometry so that Euclidean distances within the latter are conserved (x).
Following thorough consideration, we come to the conclusion that the two stiff transformations listed below must be used:
Vertical translation 7 units to the plus side.
reflection along the y = 5 line.
The collection of x-values necessary for the function to exist is represented by the solution set. Due to the fact that both functions are quadratic equations, the entire real domain is described by their solutions.

The average cost of a pizza in 2022 is $18. Inflation has been averaging 3.25% for many years. In what year was the average cost of a pizza 9$ (half)? Approximate using rule of 72.
Therefore , the solution of the given problem of average comes out to be the average price of a pizza in 2000 was about $9 (or half of $18).
Explain average.An organised collection's median value is the precise value that makes up the collection's mean. In this case, the ratio between the lowest and highest 50% of the data is a normal but rather probability measure. When finding the middle and mode, a variety of algorithms can be applied in order to identify any unusual or even amounts of values.
Here,
By dividing 72 by the interest rate, we can calculate how many years it will take an investment to double in value at a specific interest rate. This is known as the law of 72. In this instance
With an inflation rate of 3.25 percent, it takes roughly how many years for the price of a pizza to double as a result of inflation:
72 / 3.25 = 22.15 years
In light of this, we can calculate that a pizza cost $9 (half of $18) roughly 22 years ago, which corresponds to the following year:
2022 - 22 ≈ 2000
As a result of inflation running at an average of 3.25% for many years, the average price of a pizza in 2000 was about $9 (or half of $18).

a) 3
b) -2
c) -1.5
d) -4
e) 1/4
How to get the slopes?
For a line that passes through two points (x₁, y₁) and (x₂, y₂), the slope is given by the formula:
a = (y₂ - y₁)/(x₂ - x₁)
So we will use that for each of the given pairs.
a) The first pair is (3, 2) and (5, 8), so the slope is:
a = (8 - 2)/(5 - 3) = 6/2 = 3
b) The pair is: (-2, -7) and (-4, -3), so the slope is:
a = (-3 + 7)/(-4 + 2) = 4/-2 = -2
c) The pair is (1, -6) and (-2, -4) so the slope is:
a = (-4 + 6)/(-2 - 1) = 2/-3 = -3/2 = -1.5
d) The pair is (4, -8) and (-2, 16) so the slope is:
a = (16 + 8)/(-2 - 4) = 24/-6 = -4
e) The pair is (-5, 10) and (7, 13) so the slope is:
a = (13 - 10)/(7 + 5) = 3/12 = 1/4

The number line that shows the number of miles where A is less expensive has a solution of x > 60
Selecting the number line that shows the number of milesFrom the question, we have the following parameters that can be used in our computation:
Option Daily Cost ($) Cost per mile ($)
A 25 0.15
B 10 0.40
So, the cost functions are
A = 25 + 0.15x
B = 10 + 0.4x
Where x is the number of miles
When A is less expensive, we have
25 + 0.15x < 10 + 0.4x
Evaluate the like terms
15 < 0.25x

The integer fraction of the expression 14x⁻², for x = 7 is 2 / 7.
How to simplify an expression?The expression is expressed as follows:
14x⁻², for x = 7
This simply implies we have to simplify the expression when x = 7.
Therefore, we have to substitute the value of x in the expression. The value of x is 7.
Hence,
using indices law,
x⁻¹ = 1 / x
Therefore,
14x⁻² = 14 / x²
Hence,
14 / x² = 14 / 7²
14 / 7² = 14 / 49
14 / 49 ÷ 7 / 7 = 2 / 7

Consider the seriessum_{n=1}^infty frac{1}{n(n+3)}Determine whether the series converges, and if it converges, determine its value. Converges (y/n): Value if convergent (blank otherwise):
The value of the series is frac{11}{18}. This series converges. To see why, we can use the comparison test with the series sum_{n=1}^infty frac{1}{n^2}, which is a known convergent series.
Specifically, we have frac{1}{n(n+3)} < frac{1}{n^2} for all n >= 1, and so by comparison, the given series converges as well.
To find the value of the series, we can use partial fractions to write:
frac{1}{n(n+3)} = frac{1}{3n} - frac{1}{3(n+3)}
Then, we can split up the series into two telescoping sums:
sum_{n=1}^infty frac{1}{n(n+3)} = sum_{n=1}^infty (frac{1}{3n} - frac{1}{3(n+3)})
= (frac{1}{3(1)} - frac{1}{3(4)}) + (frac{1}{3(2)} - frac{1}{3(5)}) + (frac{1}{3(3)} - frac{1}{3(6)}) + ...
Notice that most of the terms cancel out, leaving us with just:
sum_{n=1}^infty frac{1}{n(n+3)} = frac{1}{3} (1 + frac{1}{2} + frac{1}{3})
= frac{11}{18}
Therefore, the value of the series is frac{11}{18}.
