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

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.

#SPJ2

Answer:

4. No solution

Step-by-step explanation:

To solve a system of equations, find the (x,y) solution that satisfies both equations. One method that can be used is substitution. It is done by substituting one function into the other function and simplify.

Substitute y = 4x - 6 into 8x - 2y = 14.

8x - 2(4x - 6) = 14

8x - 8x + 12 = 14

12 = 14 FALSE

Since the variable was eliminated and a false statement was found, there is no solution to this system.

Solve 3 and 5 similarly. If the variable is eliminated again, but a true statement is fund then the solution is infinite. If the variable is not eliminated then substitute it back into one equation to find the other.

Final answer:

Using the substitution method, we find that Problem 4 has no solution (D), Problem 3 also has no solution (A), and Problem 5 has an infinite number of solutions (C).

Explanation:

To solve the given systems of equations using the substitution method, we substitute the expression for y from the first equation into the second equation and solve for x. Once x is found, we plug it back into the first equation to find y.

Problem 4:

Starting with the equations:

y = 4x – 6

8x – 2y = 14

We substitute the first equation into the second equation:

8x – 2(4x – 6) = 14

Solving for x:

8x – 8x + 12 = 14

x = 1/2 (not a solution, as the x terms cancel out)

Since the equation simplifies to 12 = 14, which is not true, we conclude that:

Option D. There is no solution.

Problem 3:

The system appears similar:

y = 3x – 7

6x – 2y = 12

Substitution gives:

6x – 2(3x – 7) = 12

And solving for x:

6x – 6x + 14 = 12

Which simplifies to 14 = 12, another impossibility.

So the answer is:

Option A. There is no solution.

Problem 5:

From our system:

y + 2x = 7

14 – 4x = 2y

We express y from the first equation:

y = 7 – 2x

Substitute it into the second one, and solve for x:

14 – 4x = 2(7 – 2x)

14 – 4x = 14 – 4x

This equation is true for all x; hence, y can be found for any corresponding x and the system has infinite solutions:

Option C. There are an infinite number of solutions.

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.

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.

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.

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 answer is:

The equation is:

[tex]Total(t)=5200*(2)^{t}[/tex]

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:

[tex]Total(t)=5200*(1+\frac{100}{100})^{t}[/tex]

[tex]Total(t)=5200*(1+1)^{t}[/tex]

[tex]Total(t)=5200*(2)^{t}[/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.

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.

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.

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.

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.

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.

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%.
