Find the volume of the cylinder. Round your answer to the nearest hundredth.
9514 1404 393
Answer:
1763.01 m³
Step-by-step explanation:
The height of the cylinder will be ...
h = (18 m)sin(60°) = 9√3 m
The volume of the cylinder is ...
V = Bh
where B is the area of the end circle.
B = πr² = π(6 m)² = 36π m²
Then ...
V = (36π m²)(9√3 m) ≈ 1763.01 m³
The volume of the cylinder is about 1763.01 m³.

What is the volume of a ball if its diameter is 6 inches? Leave your answer in terms of π.
A) V = 12 π cubic inches
B) V = 36 π cubic inches
C) V = 288 π cubic inches
D) V = 27.75 π cubic inches
Answer:
B
Step-by-step explanation:
I am assuming that this ball is a perfect sphere.
The volume of a sphere is [tex]\frac{4}{3} *\pi *r^3[/tex]
We have the diameter, and in order to find the radius, we just have to divide by 2. 6/2=3. Now, we have to plug in the 3 to the equation.
[tex]\frac{4}{3} *\pi *3^3[/tex]
3 cubed is 27, so now we have [tex]\frac{4}{3} *\pi *27[/tex]
27*4/3*pi=36pi
Aram has been studying the mathematics behind pinball machines. He made the following diagram of one of his
observations. Determine the measure of the missing angle.
Given:
A diagram of Aram's observations.
To find:
The measure of the missing angle.
Solution:
From the given figure it is clear that the three angles [tex]52^\circ,x^\circ,68^\circ[/tex] lie on a single point and right side of a straight line.
So, the sum of angle [tex]52^\circ,x^\circ,68^\circ[/tex] must be [tex]180^\circ[/tex].
[tex]52^\circ+x^\circ+68^\circ=180^\circ[/tex]
[tex]x^\circ+120^\circ=180^\circ[/tex]
[tex]x^\circ=180^\circ-120^\circ[/tex]
[tex]x^\circ=60^\circ[/tex]
Therefore, the measure of the missing angle is [tex]x^\circ=60^\circ[/tex].
Match each function with its inverse function. Use function composition to determine your answers.
Please help
Answer:
For f(x) = x^2 - 2x + 1, the inverse is g(x) = √x + 1
For f(x) = 2 - 5*x the inverse is g(x) = (2 - x)/5
For f(x) = 5*(x - 2) the inverse is g(x) = x*(1/5) + 2
for f(x) = (x - 2)^2 - 1 the inverse is g(x) = √(x + 1) + 2
Step-by-step explanation:
If we have two functions f(x) and g(x) such that these functions are inverse, then we have:
f( g(x)) = x
and
g( f(x)) = x
Let's start with the function:
f(x) = x^2 - 2x + 1
Notice that we can rewrite this as:
f(x) = x^2 - 2*x + 1 = (x - 1)^2
Because this is a quadratic function, the inverse function needs to have a square root, then the inverse function can be the third or fourth one.
Let's try with the last one:
g(x) = √x + 1
Then:
f( g(x)) = ( √x + 1 - 1)^2 = (√x )^2 = x
g( f(x)) = √(x - 1)^2 + 1 = (x - 1) + 1 = x
Then for the function:
f(x) = x^2 - 2x + 1, the inverse is: g(x) = √x + 1
Now let's find the inverse for the second function:
f(x) = 2 - 5*x
The inverse of this function will be also a linear function, and the slope of the inverse will be the inverse of this slope, then the inverse may be the first or second options.
Let's try with:
g(x) = (1/5)*x - 2
Then:
f( g(x) ) = 2 - 5*((1/5)*x - 2) = 2 - x + 10
Then this g(x) is not the inverse of the function.
Let's try with g(x) = (2 - x)/5
Then:
f( g(x)) = 2 - 5*(2 - x)/5 = 2 - 2 + x = x
g( f(x)) = (2 - 2 - 5*x)/5 = 5*x/5 = x
For the function f(x) = 5*(x - 2)
The inverse should be the remaining linear function:
g(x) = x*(1/5) + 2
Then:
f( g(x)) = 5*(x*(1/5) + 2 - 2) = 5*x*(1/5) = x
g( f(x)) = (5*(x - 2) )*(1/5) + 2 = (x - 2) +2 = x
For the last function, f(x) = (x - 2)^2 - 1
The inverse function will be:
g(x) = √(x + 1) + 2
The compositions are:
f( g(x)) = (√(x + 1) + 2 - 2)^2 - 1 = (√(x + 1))^2 - 1 = (x + 1) - 1 = x
g(f(x)) = √((x - 2)^2 - 1 + 1) + 2 = √((x - 2)^2 + 2 = x

Select the three ratios that represent the numbers of blue marbles to red marbles, there are 6 blue marbles and 9 red marbles
Answer:
6:9 or (2:3)
Step-by-step explanation:
A ratio is a term that gives comparison of values. It helps to determine
how much of a particular thing that is compare to other thing.
Given:
numbers of blue marbles= 6
numbers of red marbles= 9
Hence, ratios that represent the numbers of blue marbles to red = 6:9
We can reduce it using factor of 3, hence the ratio becomes(2:3)

Identify all integers less than -14.
Answer:
An integer is a whole number that can be either greater than 0, called positive, or less than 0, called negative.
Step-by-step explanation:
Answer:
-28, -19, -18, -15,
Step-by-step explanation Cause -14 is more closer to 0 then all 4 of those negative numbers so that mean all 4 of these negative numbers are greater than -14 :) if that makes sense

The circumference of a circle is about 50 centimeters (cm). Which is closest to the length of its radius? You may use 3.14 for
Α.4 cm
B. 8 cm
C.16 cm
D.32 cm
Answer:
8 cm
Step-by-step explanation:
The formula of circumference is c= πd------(1)
where C = circumference, π = 3.14 and d = diameter
as we know that diameter is equal to d= 2r
put the diameter formula in eq(1)
we get c= π2r-------(2)
from eq (2) separate r means radius
hence, r= c/(π2)------(3)
put the values in eq(3)
and radius is equal to 8 cm.
