Which is the volume of the cone shown below
A 2016
B 1344
C 504
D 4032
The volume of a cone is given by the formula V = (1/3) * π * r^2 * h Where the volume of this cone is approximately A:2016.
What is volume of cone?The volume of a cone is a measure of the amount of space inside the cone.
It is calculated using the formula: V = (1/3) * π * r^2 * h, where V is the volume, r is the radius of the base of the cone, h is the height of the cone, and π is the mathematical constant pi (approximately equal to 3.14).
The volume of the cone is the amount of space inside the cone, and is measured in cubic units (such as cubic centimeters, cubic meters, etc.).
From the diagram, we can see that the radius of the base of the cone is 4 and the height is 8. Plugging these values into the formula, we get:
V = (1/3) * π * 4^2 * 8
V = (1/3) * π * 16 * 8
V = (1/3) * 64π
The volume of this cone is approximately A:2016.

TOP Electronics is a small business with five employees. The mean (average) weekly salary for the five
employees is $360. If the weekly salaries of four of the employees are $340, $340, $345, and $425, what is
the salary of the fifth employee?
The answer is $350
How to find the Median?By ranking the wages of a group of employees in descending order, you may determine the median base salary by finding the wage that is in the Middle of the distribution . 50 percent of earnings fall below the median, while 50 percent of salaries rise above the median.
ExplanationThe average of a set of numbers is known as the mean. If there are five salaries involved and the mean is $360, the total can be calculated by
Average = Total / number
Total = (Average)(Number)
Total = $360 * 5 = $1800
Four of the wages are spoken for, so we add them up and take $1800 out of the equation to get our result.
so $340 + $340 + $345 + $425 = $1450
and $1800 - $1450 = $350

Let V be the set of all positive real numbers. Define + by U+V = UV-1 and . by C.V = V. Is V a vector space? Explain?
No, V is not a vector space with the operations defined in this way. Because the operations defined in this question do not satisfy the properties required for V to be a vector space.
A vector space is a collection of objects (vectors) that can be added together and multiplied ("scaled") by numbers, called scalars. These operations must satisfy certain properties to be considered a vector space.
For example, one of the properties is the associativity of vector addition, which means that (u + v) + w = u + (v + w) for any vectors u, v, and w in V. However, with the given definition of +, we have (U + V) + W = (UV-1) + W = U(VW-1) which is not equal to U + (V + W) = U(VW-1)
Another property is the distributivity of scalar multiplication over vector addition, which means that c(u + v) = cu + cv for any scalar c and any vectors u and v in V. But with the given definition of ., we have C(U+V) = C(UV-1) which is not equal to C.U + C.V = CUV-1
Furthermore, with the definition given the additive identity and the existence of additive inverse are not guaranteed.
Therefore, V is not a vector space with the operations defined in this way.

Omar needs to invest $9,788, to the nearest dollar, for the value of the account to reach $32,400 in 20 years
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n[tex])^{nt}[/tex]
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for
Given:
Omar is going to invest in an account paying an interest rate of 6% compounded monthly.
A = $32,400 in 20 years
First, convert R as a percent to r as a decimal
r = R/100
r = 6/100
r = 0.06 per year,
Then, solve the equation for P
P = A / (1 + r/n[tex])^{nt}[/tex]
P = 32,400.00 / (1 + 0.06/12[tex])^{(12)(20)}[/tex]
P = 32,400.00 / (1 + 0.005[tex])^{240}[/tex]

The population of a city was 34,000 at the beginning of 1937. Its
population steadily increased by 6.8% every year from 1937 to 1997.
Which of these is the closest to the population of the city at the end of
1970?
Answer:
298078.228074
Step-by-step explanation:
we add 6.8% of the population to the city each year
city population in year x + 1 = city population in year x + 6.8% of city population in year x = city population in year x + 0.068 * city population in year x = 1 * city population in year x + 0.068 * city population in year x = 1.068 * city population in year x
we multiply the population by 1.068 each year to get the next year's population
thus, over a period of y years, we would multiply the population by 1.068 y times.
start = 34000 in 1937
difference in years = 1970 - 1937 = 33
final amount = 34000 * 1.068 33 times = 34000 * 1.068^33 = 298078.228074

How to find the side of a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
The sine law can be used to find the side of a triangle. Therefore, let's find the side f of the triangle using sine law.
Therefore,
a / sine A = b / sin B = c / sin C
Hence,
e / sin E = f / sin F
E = 180 - 104 - 52
E = 24 degrees
Therefore,
1.8 / sin 24 = f / sin 104
cross multiply
1.8 sin 104 = f sin 24
divide both sides by sin 24
f = 1.8 sin 104 / sin24
f = 1.8 × 0.97029572627 / 0.40673664307

A contour map/ plot is a way of representing a function with a two-dimensional input and a one-dimensional output.
Contours are obtained by intersecting the surface with the horizontal plane using the equation z = c. So the contour equation at height c is f(x,y) = c.
There are three types of contour lines displayed on the map:
Intermediate, Index, Supplement. The index line is the thickest contour line, and the points along the line are usually function numbered. Contours do not branch or split. Page 5 Steep slopes are represented by dense contour lines. Contour lines never intersect, but they can touch.
