Answer:
75 cubic centimeters
Step-by-step explanation:
Volume of a cone is the area of the base times a third of the height.
The base is a circle.
The formula for the area of a circle is [tex]\pi \cdot r^2[/tex].
We are given that we want to use [tex]3.14[/tex] for [tex]\pi[/tex] and
r=(diameter)/2=6/2=3 cm.
So the area of the base is [tex]3.14 \cdot 3^2=28.26[/tex].
Now the height of the cone is 8 cm.
A third of the height is 8/3 cm.
So we want to compute area of base times a third of the height.
Let's do that:
[tex]\frac{8}{3} \cdot 28.26[/tex]
75.36 cubic centimeters
To the nearest cubic centimeters this is 75
To calculate the volume of a cone, we use the formula for the volume of a cone, which is:
\[ V = \frac{1}{3} \pi r^2 h \]
Where:
- \( V \) is the volume of the cone
- \( \pi \) is the constant Pi (approximated as 3.14)
- \( r \) is the radius of the cone's base
- \( h \) is the height of the cone
Given that the diameter of the cone is 6 cm, we find the radius by dividing the diameter by 2:
\[ r = \frac{diameter}{2} = \frac{6 cm}{2} = 3 cm \]
Now we have the radius and the height (which is given as 8 cm), we can substitute these values into the formula:
\[ V = \frac{1}{3} \pi r^2 h = \frac{1}{3} \times 3.14 \times (3 cm)^2 \times 8 cm \]
First, square the radius:
\[ (3 cm)^2 = 9 cm^2 \]
Now, perform the multiplication:
\[ V = \frac{1}{3} \times 3.14 \times 9 cm^2 \times 8 cm \]
\[ V = 3.14 \times 3 cm^2 \times 8 cm \]
\[ V = 9.42 cm^2 \times 8 cm \]
\[ V = 75.36 cm^3 \]
Finally, you want to round the volume to the nearest cubic centimeter. Since \( 75.36 \) is already a decimal to the nearest hundredth and has no fractional part in cubic centimeters, we simply round it to the nearest whole number:
\[ V \approx 75 \]
So, the volume of the cone is approximately \( 75 \) cubic centimeters.

Determine the slant asymptote for the function f(x)=3x^2-4x + 5/ x-3
Answer:
y=3x+5
Step-by-step explanation:
To determine the slant asymptote you must perform polynomial division and also the degree of the numerator must be one greater than degree of the denominator for it to even exist. (We do have that here by the way since degree of the top is 2 and the degree of the bottom is 1).
Let's begin the division process:
I'm using synthetic. You can also use long.
3 goes on the outside because we are dividing by x-3
3 | 3 -4 5
| 9 15
----------------------
3 5 20
So [tex]\frac{3x^2-4x+5}{x-3}=3x+5+\frac{20}{x-3}[/tex]
So the slant aymptote is y=3x-5 since 20/(x-3) approaches 0 as x approaches infinity.
To find the slant asymptote of the given function, perform long division to divide the numerator by the denominator. As x approaches infinity, the slant asymptote is 3x + 5.
Explanation:To find the slant asymptote of the function f(x) = (3x^2 - 4x + 5) / (x - 3), we need to determine what happens as x approaches positive or negative infinity. We can do this by dividing the numerator polynomial by the denominator polynomial using long division.
Performing long division, we get:
3x^2 - 4x + 5 / (x - 3) = 3x + 5 + (8 / (x - 3))
As x approaches infinity, the 8 / (x - 3) term becomes negligible and we are left with the slant asymptote:
f(x) = 3x + 5

Cary earns $975 each month on his part-time job. How much money does he earn in a year
Answer:
$11,700
Step-by-step explanation:
If Cary earns $975 each month on his part-time job, he would earn $11,700 in a year.
1 year = 12 months
$975 per month
975 x 12 = 11700
In this question, we're going to need to find out how much Cary earns in a year.
To do this, we need to go back to the problem to see if we can get some valuable information.
We know that Cary earns $975 each month.
With the information above, we can solve the problem.
There are 12 months in a year, so that means we're going to multiply 975 by 12 in order to find out how much Cary earns in a year.
975 × 12 = 11,700
When you multiply, you would end up with the answer "11,700"
This means that Cary earns $11,700 in a year

The product of two consecutive positive integers is 342. Represent in the above situation in the form of quadratic equation. Find the numbet also.
Answer:
18 and 19
Step-by-step explanation:
Consecutive positive integers have a difference of 1 between them
let n and n + 1 be the 2 integers, then
n(n + 1) = 342, that is
n² + n = 342 ( subtract 342 from both sides )
n² + n - 342 = 0 ← quadratic equation in standard form
(n + 19)(n - 18) = 0 ← in factored form
Equate each factor to zero and solve for n
n + 19 = 0 ⇒ n = - 19
n - 18 = 0 ⇒ n = 18
However, n > 0 ⇒ n = 18 and n + 1 = 18 + 1 = 19
The 2 integers are 18 and 19
the radius of Earth is 6400 km. the distance of the moon from the Earth's surface is 380000 km. find the radius of the moon which subtends an angle of 20'at the centre of the earth
Answer:
1100 km
Step-by-step explanation:
The problem doesn't clearly state whether the 380,000 km is from the Earth's surface to the moon's center, or to the moon's surface. Since we'll be rounding to 2 significant figures, it's not enough to make a difference, so I'll assume it's to the moon's center.
Draw circle representing the moon and earth. Draw tangent lines from the earth's center to the edge of the moon. The angle between these lines is the subtended angle. Now draw a line representing the moon's radius from the center of the moon to the point where the tangent line intersects. Notice this forms a right angle.
(See attached diagram)
Using trigonometry:
sin(θ/2) = r / (R + h)
r = (R + h) sin(θ/2)
Given that R = 6400 km, h = 380,000 km, and θ = 20' = 1/3 degrees:
r = (6400 + 380000) sin(1/6 °)
r = 1100
The moon's radius is 1100 km.
what is the inverse operation of F(x)=2x+3
Answer:
[tex]f^{-1}[/tex](x) = [tex]\frac{x-3}{2}[/tex]
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = 2x + 3 ( subtract 3 from both sides )
y - 3 = 2x ( divide both sides by 2 )
[tex]\frac{y-3}{2}[/tex] = x
Change y back into terms of x, hence
[tex]f^{-1}[/tex](x ) = [tex]\frac{x-3}{2}[/tex]
Keep in mind that f(x) means the same thing as y so...
y = 2x + 3
To find the inverse operation you switch the places of x and y like so...
x = 2y + 3
Now you must solve for y. To start off you must subtract 3 to both sides.
x - 3 = 2y + 3 - 3
x - 3 = 2y
Now divide 2 to both sides to completely isolate y
(x - 3) / 2 = 2y / 2
[tex]\frac{1}{2} x - \frac{3}{2}[/tex] = y
OR
[tex]\frac{x}{2} -\frac{3}{2}[/tex] = y

ABCD is an isosceles trapezoid with AD II BC, mZB = 60°, and mZC = (3x +15) Solve for x.
A 15
B. 25
C. 35
D. 60
Answer:
A 15
Step-by-step explanation:
In an isosceles trapezoid, each pair of base angles is congruent.
In this isosceles trapezoid, angles B and C are congruent, so their measures are equal.
m<B = m<C
60 = 3x + 15
Subtract 15 from both sides.
45 = 3x
Divide both sides by 3.
15 = x
x = 15
Answer: The correct option is (A) 15.
Step-by-step explanation: As shown in the attached figure below, ABCD is an isosceles trapezoid with AD parallel to BC.
Also, m∠B = 60° and ∠C = (3x +15)°.
We are to find the value of x.
Since ABCD is an isosceles trapezoid with AB and CD as the two legs, so we have
[tex]AB=CD\\\\\Rightarrow m\angle C=m\angle B~~~~~~~~~~~~~~~~~~~[\textup{Angles opposite to equal legs are equal}]\\\\\Rightarrow (3x+15)^\circ=60^\circ\\\\\Rightarrow 3x+15=60\\\\\Rightarrow 3x=60-15\\\\\Rightarrow 3x=45\\\\\Rightarrow x=\dfrac{45}{3}\\\\\Rightarrow x=15.[/tex]
Thus, the required value of x is 15.
Option (A) is CORRECT.

In the picture I graphed (0,1) and then graphed (1,3).
I connected the points with a straight-edge.
Step-by-step explanation:
This question is asking us to use slope-intercept form of a line to answer it.
Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.
Your equation is y=2x+1 so our m=2 and b=1.
So our y-intercept is 1. This is the first point we graph.
The slope is 2 or as a fraction 2/1. Recall that slope=rise/run. So this tells us after we plot (0,1) we need to go up 2 units and right 1 unit to get one more point to graph. This point will be (0+1,1+2) or just (1,3).

Step-by-step explanation:
Hello!
To graph a line, we just need any two points that belong to that line.
We know the y-intercept, (0,1), given in the equation itself. We can plot that point as our first point.
The second point can be found by using the slope. The slope is 2/1, and we can go up 2 units and to the right 1 unit to find the second point.
The second point is (1,3).

In the given scenario regarding a toy sinking in a pool, the constraints related to the depth of the pool and the rate of sinking of the toy could be part of the scenario, which illustrates a system of inequality related to the depth of the toy in the pool over time.
Explanation:The question requires understanding of the constraints in a scenario that involve a system of inequalities related to the depth of a toy in a pool over time. In this case, the toy is falling, or sinking, into the pool. Therefore, the scenario will involve the depth of the pool and the rate at which the toy is falling.
Firstly, The depth of the pool is important because the toy cannot sink deeper than the pool is. Therefore, both constraints A) The pool is 1 meter deep and B) The pool is 2 meters deep could both be part of the scenario, depending on the actual depth of the pool involved.
Secondly, The rate at which the toy is falling (sinking) is also important. Both constraints C) The toy falls at a rate of at least a 1/2 meter per second and D) The toy sinks at a rate of no more than a 1/2 meter per second could be part of the scenario, depending on the actual sinking rate of the toy.

The constraint that could be part of the scenario is that the D) toy sinks at a rate of no more than a 1/2 meter per second.
Explanation:A system of inequalities is a set of two or more inequalities involving the same variables. The solution to the system is the set of values that satisfy all the inequalities simultaneously. Graphically, the solution represents the overlapping region of the individual inequalities on a coordinate plane.
The constraint that could be part of the scenario is that the toy sinks at a rate of no more than a 1/2 meter per second. This constraint ensures that the depth of the toy in the pool does not change too rapidly. If the toy sank at a faster rate than 1/2 meter per second, it would quickly reach the bottom of the pool.

[tex]\[ V_{box} = \frac{95^3}{10^3} \][/tex]
[tex]\[ V_{box} = \frac{95^3}{1000} \][/tex]
[tex]\[ V_{box} = \frac{857375}{1000} \][/tex]
[tex]\[ V_{box} = \frac{1919}{4} \][/tex] cubic inches.
Next, we calculate the volume of the basketball. The basketball is a sphere with a diameter of 9.5 inches, so its radius [tex]\( r \)[/tex] is half of that:
[tex]\[ r = \frac{9.5}{2} \][/tex]
[tex]\[ r = \frac{95}{20} \][/tex]
[tex]\[ r = \frac{19}{4} \] inches.[/tex]
The volume of a sphere [tex]\( V_{sphere} \)[/tex] is given by the formula:
[tex]\[ V_{sphere} = \frac{4}{3}\pi r^3 \][/tex]
[tex]\[ V_{sphere} = \frac{4}{3}\pi \left(\frac{19}{4}\right)^3 \][/tex]
[tex]\[ V_{sphere} = \frac{4}{3}\pi \left(\frac{19^3}{4^3}\right) \][/tex]
[tex]\[ V_{sphere} = \frac{4}{3}\pi \left(\frac{6859}{64}\right) \][/tex]
[tex]\[ V_{sphere} = \frac{481\pi}{128} \] cubic inches.[/tex]
Now, we subtract the volume of the basketball from the volume of the box to find the volume of the empty space [tex]\( V_{empty} \):[/tex]
[tex]\[ V_{empty} = V_{box} - V_{sphere} \][/tex]
[tex]\[ V_{empty} = \frac{1919}{4} - \frac{481\pi}{128} \] cubic inches.[/tex]
To simplify the expression, we can multiply the terms by a common denominator of 128 to combine them:
[tex]\[ V_{empty} = \frac{1919 \times 32}{128} - \frac{481\pi}{128} \][/tex]
[tex]\[ V_{empty} = \frac{61408}{128} - \frac{481\pi}{128} \][/tex]
[tex]\[ V_{empty} = \frac{61408 - 481\pi}{128} \] cubic inches.[/tex]
However, we notice that the denominator of 128 can be simplified by dividing both numerator and denominator by 4, which gives us the final
[tex]\[ V_{empty} = \frac{1919}{16} - \frac{481\pi}{128} \][/tex] cubic inches.
Therefore, the volume of the empty space in the box is [tex]\(\boxed{\frac{1919}{16} - \frac{481\pi}{128}}\)[/tex] cubic inches.

Answer:
The polyester in standard form with zero placeholders is
-x^6+0x^5+3x^4+-7x^3+4x^2+0x+-1
7th term -1
6th term 0x
5th term 4x^2
4th term -7x^3
3rd term 3x^4
2nd term 0x^5
1st term -x^6
Step-by-step explanation:
We want to write 4x^2-7x^3-x^6+3x^4-1 in descending order means want the exponents to being counting down.
6 is the highest exponent so lets rearrange this so that tern comes first:
-x^6+.....
5 is the highest but we are missing so now we have:
-x^6+0x^5+....
4 is the next highest and I see +3x^4 in our polynomial so that comes next:
-x^6+0x^5+3x^4+...
3 is the next highest and I see -7x^3 so that term comes next:
-x^6+0x^5+3x^4+-7x^3+....
2 is the next highest and I see +4x^2 so that term comes next:
-x^6+0x^5+3x^4+-7x^3+4x^2+...
1 is the next highest and we are missing an x term so the next term is +0x.....
-x^6+0x^5+3x^4+-7x^3+4x^2+0x+....
0 is the next highest and will be the last term we write. This is the constant tern, the term without the variable and that is -1.
-x^6+0x^5+3x^4+-7x^3+4x^2+0x+-1
Now I guess you are reading this from left to right when numbering the terms as first, second, and so on...
1st term -x^6
2nd term 0x^5
3rd term 3x^4
4th tern -7x^3
5th term 4x^2
6th term 0x
7th term -1
Which of the following does not describe a rigid motion transformation?
The transformation which do not describe a rigid motion transformation is:
Option: C
C. dilating a figure by a scale factor of 1/4
Step-by-step explanation:Rigid motion transformation is a transformation in which the shape and size of the figure is preserved i.e. it remains the same.
A)
Translating a figure 5 units right.
We know that in the translation transformation the shape and size of the figure remains the same only the location of points are changed.
B)
Rotating a figure 90 degrees.
In rotation the shape and size is preserved.
Hence it is a rigid transformation.
C)
dilating a figure by a scale factor of 1/4
This is not a rigid transformation because the size of the figure is changed.
since the scale factor is less than 1.
Hence, the transformation is a reduction of the original figure.
D)
reflecting a figure across the x-axis.
The reflection is also a rigid transformation.
since it preserves the shape and size of the object.
Answer:
The correct answer is C.
