Answer:
r=3x
Step-by-step explanation:
The Volume of a Cone
The volume of a cone of radius r and height h is:
[tex]\displaystyle V=\frac{1}{3}\pi hr^2[/tex]
We are given the volume of a cone is
[tex]V=3\pi x^3[/tex]
Equating:
[tex]\displaystyle \frac{1}{3}\pi hr^2=3\pi x^3[/tex]
Multiplying by 3:
[tex]\pi hr^2=9\pi x^3[/tex]
Simplifying by pi:
[tex]hr^2=9 x^3[/tex]
Since h=x:
[tex]xr^2=9 x^3[/tex]
Dividing by x:
[tex]r^2=9 x^2[/tex]
Taking square roots:
[tex]r=\sqrt{9 x^2}=3x[/tex]
Thus: r=3x
Answer:
3x

Step-by-step explanation:
The students in a college marching band are arranged in rows. The recursive rule f(n) = f(n − 1) + 8 and f(1) = 13 gives the number of students in each row, where n is the row number. All of the clarinet players are in row 1, and all of the trumpet players are in row 4. How many more trumpet players than clarinet players are there? Complete the explanation.
Answer:
There are 24 more trumpet players than clarinet players
Step-by-step explanation:
The given information are;
The recursive rule or the number of band members in a row is f(n) = f(n - 1) + 8
Where f(1) = 13
The members of the band players in row 1 = The clarinet players
The members of the band players in row 4 = The trumpet players
Therefore, the number of clarinet players = f(1) = 13
The number of band members in row 2, f(2) = f(1) + 8 = 13 + 8 = 21
The number of band members in row 3, f(3) = f(2) + 8 = 21 + 8 = 29
The number of band members in row 4, f(4) = f(3) + 8 = 29 + 8 = 37
Therefore, given that the trumpet players are in row 4, the number of trumpet players = The number of band members in row 4 = 37 Trumpet players
The difference in the number of trumpet and clarinet = The number of more trumpet players than clarinet players = 37 - 13 = 24 more trumpet players than clarinet players
There are 24 more trumpet players than clarinet players.

If the point of the preimage is (5,2) and the point of the image is (1,2), what RULE was applied to the preimage to obtain the image?
A) (x, y + 4)
B) (x + 4, y)
C) (x - 4, y)
D) (x, y - 4)
Explanation:
We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.
The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.
Overall, the rule is [tex](x,y) \to (x-4, y)[/tex] which translates the point 4 units to the left.
The graphs of f(x) and g(x) are shown below.

yes

Answer:
For the first question, the slope is -3.
For the second question, the point is (-6,7)
Step-by-step explanation:
In point-slope form, to identify the slope, its the number that's before the parenthesis, which in this case, its -3.
In point-slope form, to identify the points, its the number that replaces y1 and x1, which in this case, its -7 and 6. However, in point-slope form, the numbers are the opposite of what they are. For an example, in this equation, -7 is negative, buts its point would actually be positive.

write 1 1/8 miles in 3/8 hour as a unit rate
help pleaseee
Answer:
3mi/hr , 3 miles per hour or 3mph
Step-by-step explanation:
so you want to find how manu milesin an hour.
first you need to gind how many miles in jsut 1/8 of the hour
so what we have is for 3/8 of an hour so divide what we have by 3
9/8 divided by 3 = 3/8 of a mile in 1/8 of an hour.
multiple this by 8 to get what equals in 1 hr
3/8*8 = 24/8 simplified to 3.
3 miles per hour
You must use 2 eggs to make 6 dozen cookies. How many eggs are needed to make 42 dozen
cookies? Use a proportion to solve.
Answer:
14 eggs
Step-by-step explanation:
Answer: It takes 14 eggs to make 42 dozen cookies
Step-by-step explanation: To solve using a proportion first start out with 2eggs/6cookies (They are in a dozen but 42 is also in a dozen so it cancels out). Now that you have 2/6 you now have to find the x in x/42. 42 divided by 6 is 7 so multiply 2 by 7 and you get: It takes 14 eggs to make 42 dozen cookies or 14/42. Hope this helps
Savannah drew a map of Texas for her Geography class. According to Savannah’s map scale, one-half inch on the map represents approximately 77.5 kilometers. If the actual distance from Austin to El Paso is approximately 930 kilometers, what is the approximate distance between Austin and El Paso on Savannah’s map?
Answer:
6 inches
Step-by-step explanation:
First, take the 930 kilometers and divide it by 77.5 kilometers. You will get 12. This means the distance between Austin and El Paso is 12 one half inches. That is equivalent to 6 inches.
