A rectangular prism has length 14 cm, width 3.4 cm, and height 11.6 cm. Identify the volume of the prism to the nearest tenth. HELP PLEASE!!
Answer:
552.16 cm^3
Step-by-step explanation:
Just multiply the lenght together.
The volume of the rectangular prism is approximately 552.16 cubic cm.
To find the volume of a rectangular prism, you need to multiply its length, width, and height.
Given that the length is 14 cm, the width is 3.4 cm, and the height is 11.6 cm, we can calculate the volume as follows:
Volume of a rectangular prism = Length × Width × Height
Volume of a rectangular prism = 14 cm × 3.4 cm × 11.6 cm
Volume of a rectangular prism ≈ 552.16 cm³ (rounded to the nearest tenth)
Therefore, the volume of the rectangular prism is approximately 552.16 cubic cm.

Twenty percent of candies in a package are red. The rest are another color.
Simulate randomly checking 20 packages for red candies using these randomly generated digits. Let the digits 1 and 2 represent a red candy.
91027 18200 74536 83514
Approximately how many red candies will be in the packages?
Answer:
Step-by-step explanation:
The probability of picking a red candy from a full bag is 0.20.
But we also have experimental information represented by those 20 digits, each of which tells us how many red candies are in each package.
In the 2nd package there is 1 red candy. In the fourth there is 1 red candy (since 2 represents a red candy, just like 1 represents a red candy).
Next, in the 6th and 8th packages there is 1 red candy each. Finally, in the 19th package there is 1 red candy. Now add up these results: the number of red candies is 1 + 1 + 1 + 1 + 1, or 5. This seems to indicate that there will be 5 red candies in the entire 20 packages.

A fireworks company has two types of rockets called Zinger 1 and Zinger 2. The polynomial -16t^2 + 150t gives the height in feet of Zinger 1 at t seconds after launch. The polynomial -16t^2 + 165t gives the height of Zinger 2 at t seconds after launch. If the rockets are launched at the same time and both explode 6 seconds after launch, how much higher is Zinger 2 than Zinger 1 when they explode? 414 ft
90 ft
324 ft
990 ft
Answer:
90 feet
Step-by-step explanation:
If we put t = 6 into both the formulas, we will get the height of each.
Zinger 1:
Height = [tex]-16t^2 + 150t[/tex]
Putting t = 6,
[tex]-16(6)^2 + 150(6)=324[/tex]
Zinger 2:
Height = [tex]-16t^2 + 165t[/tex]
Putting t = 6,
[tex]-16(6)^2 + 165(6)=414[/tex]
The difference in height is 414 - 324 = 90 feet

Answer:
Area of rectangle = 40 square units
Step-by-step explanation:
Points to remember
Distance formula
Length of a line segment with end points (x₁, y₁) and (x₂, y₂) is given by,
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Area of rectangle = Length * Breadth
To find the length and breadth
Here a rectangle with vertices at (7, 3), (12, 3), (12, 11), and (7, 11)
Length1 = √[(x₂ - x₁)² + (y₂ - y₁)²]
√[(12 - 7)² + (3 - 3)²] = √5² = 5
Length2 = √[(x₂ - x₁)² + (y₂ - y₁)²]
√[(12 - 12)² + (11 - 3)²] = √8² = 8 units
Therefore Length of rectangle = 8 and
Breadth of rectangle = 5 units
To find the area of rectangle
Area = Length * Breadth
= 8 * 5 = 40 square units

The function F is defined by F(x)= 12 x + 1 2 . Use this formula to find the following values of the function:
F(3)
F(-12)
F(1/3)
F(3/4)
F(k)
F(a/2)
F(x-1)
F(x+h)
Just solving for one of these would be really helpful!
Answer:
Step-by-step explanation:
I will assume that you meant F(x)= 12x + 12. If you meant a fraction, write 1/2.
Then F(3) = 12(3) + 12 = 48
F(-12) = 12(-12) + 12 = -132.
F(1/3) = 12(1/3) + 12 = 4 + 12 = 16
Please verify what you meant. Then I will answer the remaining questions.
[tex]\(F(3) = 48\), \(F(-12) = -132\), \(F\left(\frac{1}{3}\right) = 16\), \(F\left(\frac{3}{4}\right) = 21\), \(F(x) = 12x + 12\).[/tex]
To find the values of the function [tex]\(F(x) = 12x + 12\)[/tex] for the given inputs:
1. F(3): Substitute x = 3 into the function: F(3) = 12(3) + 12 = 36 + 12 = 48.
2. F(-12): Substitute x = -12 into the function: F(-12) = 12(-12) + 12 = -144 + 12 = -132.
3. [tex]\(F\left(\frac{1}{3}\right)\)[/tex]: Substitute [tex]\(x = \frac{1}{3}\)[/tex] into the function: [tex]\(F\left(\frac{1}{3}\right) = 12\left(\frac{1}{3}\right) + 12 = 4 + 12 = 16\).[/tex]
4. [tex]\(F\left(\frac{3}{4}\right)\)[/tex]: Substitute [tex]\(x = \frac{3}{4}\)[/tex] into the function: [tex]\(F\left(\frac{3}{4}\right) = 12\left(\frac{3}{4}\right) + 12 = 9 + 12 = 21\).[/tex]
5. F(k): Substitute x = k into the function: F(k) = 12k + 12.
6. [tex]\(F\left(\frac{a}{2}\right)\)[/tex]: Substitute [tex]\(x = \frac{a}{2}\)[/tex] into the function: [tex]\(F\left(\frac{a}{2}\right) = 12\left(\frac{a}{2}\right) + 12 = 6a + 12\).[/tex]
7. F(x-1): Substitute x = x-1 into the function: F(x-1) = 12(x-1) + 12 = 12x - 12 + 12 = 12x.
8. F(x+h): Substitute x = x+h into the function: F(x+h) = 12(x+h) + 12 = 12x + 12h + 12.
These are the values of the function for the given inputs.
For the function below, state the x-coordinate of the x-intercept that is located to the fight of the origin.
[tex]f(x)=x^3-9x[/tex]
Answer:
x = 3
Step-by-step explanation:
It should NOT be "fight of the origin", rather "right of the origin".
Now let's move on to solve the question...
The x-intercept is found by setting the function equal to 0. Thus:
0 = x^3 - 9x
Let's solve this using algebra:
[tex]0=x^3-9x\\0=x(x^2-9)\\0=x(x-3)(x+3)[/tex]
Hence, x = -3 and x = 3
The coordinate that is to the right of the origin is the positive one, so x = 3 is the x-intercept we are looking for.
In the playoffs, the Algenauts won their division playoff series 3 games to 1 and then beat their arch-rivals the Geometers in the League Championship series 4 games to 2. If the Algenauts won 80% of their home playoff games and 60% of their away playoff games, what percentage of their playoff games were at home?
Answer:
h = 48
Step-by-step explanation:
So they played 48 home games. They won 3/4, so they won 36 and lost 12.
They played 48 away games. They won 2/3, so they won 32 and lost 16.
All tolled, they won 36 + 32 = 68 games and lost 12 + 16 = 28 games.
To calculate the percentage of home playoff games played by the Algenauts, we use a system of equations with the known win rates and number of games played. Solving, we find that approximately 71.43% of their playoff games were at home.
The student is asking about the percentage of home playoff games played by the Algenauts. The Algenauts won 3 division playoff games and then beat their rivals, the Geometers, with a score of 4-2. Given their win rates of 80% for home games and 60% for away games, we can calculate the percentage of games played at home using a system of equations.
Let H be the number of home games and A be the number of away games. Since the Algenauts played a total of 3 + 4 = 7 games, and won 3 + 4 = 7 games, we have the following equations:
H + A = 7 (total games)
0.80H + 0.60A = 7 (total games won)
Solving the system of equations, we get H = 5 and A = 2, meaning 5 out of the 7 games were played at home. Therefore, the percentage of home games is (5/7) * 100, which equals approximately 71.43%.
Which represents the solution(s) of the system of equations, y + 4 = x2 and y – x = 2? Determine the solution set by graphing.
Answer:
(x,y) = (-2, 0)
and
(x,y) = (2.5, 2.25)
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equations.
Please see the attached image below, to find more information about the graph

The equations are:
y1 + 4 = x^2
y1 = x^2 - 4
y2 - x = 2
y2 = x +2
The intersection of the two graphs correspond to
(x,y) = (-2, 0)
and
(x,y) = (2.5, 2.25)
Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 3, negative 2, and 2
Which of the following functions best represents the graph?
f(x) = x3 + x2 − 4x − 4
f(x) = x3 + x2 − x − 1
f(x) = x3 + 3x2 − 4x − 12
f(x) = x3 + 2x2 − 6x − 12
Answer:
f(x) = x3 + 3x2 − 4x − 12
Step-by-step explanation:
A polynomial which falls tot he left and rises to the right is a function with a positive leading coefficient. Its formed by the x-intercepts or zeros x = -3, -2 and 2. The zeros form the factors (x+3)(x+2)(x-2). Multiply the factors using the distributive property to find the function in standard form.
(x+3)(x+2)(x-2)
(x^2 + 3x + 2x + 6)(x-2)
(x^2 + 5x + 6)(x-2)
x^3 + 5x^2 + 6x -2x^2 - 10x - 12
x^3 + 3x^2 - 4x - 12
If f(x) = x^2 I horizontally compressed to g(x) which could be the equation of g(x)?
A. [tex]g(x) =( \frac{1}{5} x)^2[/tex]
B. [tex]g(x) = x^2+5[/tex]
C. [tex]g(x) = (5x)^2[/tex]
D.[tex]g(x) = (x-5)^2[/tex]
Answer: Option C.
Step-by-step explanation:
For a parent function [tex]f(x)=x^2[/tex], you have these transformations:
If [tex]f(x)=c(x^2)[/tex] and [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor "c".
If [tex]f(x)=c(x^2)[/tex] and [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor "c"
If [tex]f(x)=(cx)^2[/tex] and [tex]0 <c <1[/tex] then the graph is stretched horizontally by a factor "c"
If [tex]f(x)=(cx)^2[/tex] and [tex]|c| > 1[/tex] then the graph is compressed horizontally by a factor "c"
In this problem we have the function [tex]f(x)=x^2[/tex] and we know that this is horizontally compressed to g(x), then the transformation is:
[tex]f(x)=(cx)^2[/tex] and the factor must be [tex]|c| > 1[/tex]
You can observe that the option that shows this form is the option C. Therefore, the equation of g(x) is:
[tex]g(x) = (5x)^2[/tex]
Where [tex]|5| > 1[/tex]
A horizontal compression of the function f(x) = x² is represented by the function g(x) = (5x)², where x is multiplied by a constant greater than 1, causing the function to be 'squeezed' together along the x-axis.
Explanation:The question is asking for a horizontal compression of the function f(x) = x². A horizontal compression occurs when we multiply the x by a constant greater than 1 inside the function parentheses. This affects the rate at which the function grows horizontally.
A good way to visualize this is by thinking of the x-axis being 'squeezed' together. Given the choices, the function that represents a horizontal compression of f(x) = x² is C: g(x) = (5x)². In this case, we are multiplying x by a constant (5), thus compressing the function horizontally compared to the original function.

To determine whether the inverse of a function is a function you can perform the horizontal line test.
true or false
Answer:
[tex]\boxed{\text{TRUE}}[/tex]
Step-by-step explanation:
If a horizontal line intersects the graph of a function in all places at exactly one point (the horizontal line test), the inverse of the function is also a function.
For example, the inverse of a hyperbola (like ƒ(x) =1/x) is a function, because every horizontal line intersects with the graph at exactly one point.
However, the inverse of a parabola (like ƒ(x) = x²) is not a function, because a horizontal line intersects with the graph at two points.

D. As the sample size is too small, the margin of error cannot be trusted..
I think the answer is A. am I correct?
A is the correct answer
Answer:
The correct option is A.
Step-by-step explanation:
An organization consists of 8,684 employees. The organization surveyed 884 of their employees and found that 36% of those surveyed disliked the new vacation policies. It means
[tex]n=884[/tex]
[tex]p=\frac{36}{100}=0.36[/tex]
The value of z-score for 95% confidence level is 1.96.
The formula for margin of error is
[tex]ME=z\times \sqrt{\frac{p(1-p)}{n}}[/tex]
Where, z is z-score at given confidence level, p is sample proportion and n is number of samples.
[tex]ME=\pm 1.96\times \sqrt{\frac{0.36(1-0.36)}{884}}[/tex]
[tex]ME=\pm 0.0316425[/tex]
[tex]ME\approx \pm 0.032[/tex]
The margin of error is ±0.032 and the sample size is appropriately large. Therefore, the correct option is A.

A bacteria culture is doubling in size of every day. If the bacteria culture starts at 5,200, write an equation for its population size,p, as a function of the number of days ,d, since it started
The answer is:
The equation is:
[tex]Total(t)=5200*(2)^{t}[/tex]
Why?It's an exponential growth problem, we can calculate the exponential growth using the following equation:
[tex]Total(t)=StartPopulation*(1+r)^{\frac{t}{2}}[/tex]
Where,
Total, is the total population after "t" time in days.
Start population, for this is equal to 5,200
r,is equal to the percent of growth, for this case it's 100% each day.
t, is the time elapsed.
So, rewriting the equation, we have:

C. 400 units^3
D. 433 units
Answer:
Hence correct choice is C. [tex]Volume=400[/tex] [tex]units^3[/tex]
Step-by-step explanation:
Given that length of the square base of the pyramid a = 10 units
Given that height of the pyramid is h = 12 units
Now question says to find the volume of the given cone.
So plug these values into formula of volume of the square pyramid.
[tex]Volume=\frac{1}{3} a^2h[/tex]
[tex]Volume=\frac{1}{3} (10)^2(12)[/tex]
[tex]Volume=\frac{1}{3} (100)(12)[/tex]
[tex]Volume=\frac{1}{3} (1200)[/tex]
[tex]Volume=400[/tex]
Hence correct choice is C.
Answer:
The correct answer is option C. 400 units³
Step-by-step explanation:
Formula:-
Volume of pyramid = (a²h)/3
Where a - side of base
h - height of pyramid
From the figure we can see a square pyramid
To find the volume of pyramid
here a = 10 units and h = 12 units
Volume = (a²h)/3 = (10² * 12)/3
= 400 units³
Roberto's toy car travels at 40 centimeters per second (cm/sec) at high speed and 15 cm/sec at low speed. If the car travels for 25 seconds at high speed and then 45 seconds at low speed, what distance would the car have traveled?
Answer:
1675 cm
Step-by-step explanation:
distance = speed · time
total distance = speed1 · time1 + speed2 · time2
= (40 cm/s)(25 s) + (15 cm/s)(45 s) = 1000 cm + 675 cm = 1675 cm
Roberto's toy car travels 1000 cm at high speed (40 cm/sec for 25 sec) and 675 cm at low speed (15 cm/sec for 45 sec), totaling 1675 cm.
Explanation:To calculate the total distance traveled by Roberto’s toy car, we need to consider the two separate speeds at which the car travels and the time it spends at each speed.
First, we calculate the distance at high speed using the formula distance = speed × time. At high speed, the car travels at 40 cm/sec for 25 seconds, so we multiply these two values to get the distance:
Distance at high speed = 40 cm/sec × 25 sec = 1000 cm
Next, we calculate the distance at low speed, where the car travels at 15 cm/sec for 45 seconds:
Distance at low speed = 15 cm/sec × 45 sec = 675 cm
Finally, we add these two distances together to find the total distance traveled by the toy car:
Total distance = Distance at high speed + Distance at low speed = 1000 cm + 675 cm = 1675 cm
Therefore, Roberto’s toy car would have traveled 1675 centimeters in total.
