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.

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:

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.

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.

Answer: Option B

Step-by-step explanation: If You Found The Area Of The Triangle You Would Get An Answer Of 36 Square Inches. Have A Great Day!

The area of a triangle with a base of 9 inches and a height of 8 inches is found using the formula A = ½ × base × height, resulting in 36 square inches.

To find the area of a triangle, the formula A = ½ × base × height is used, where A represents the area, base is the length of the base of the triangle, and height is the measure from the base to the opposite vertex at a right angle. In this instance, the base of the triangle is 9 inches and the height is 8 inches. By plugging these values into the formula, you get the following calculation:

A = ½ × 9 in × 8 in = ½ × 72 in² = 36 in²

Therefore, the area of the triangle is 36 square inches.

Answer:

C. 1/8

Step-by-step explanation:

This is because the number two goes into sixteen eight times. This is the simplest form of the fraction.

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%.

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.

Only two cards are drawn, so it is impossible for three of them to be pink.

If you meant to type that two of them were pink cards, then the answer is B. 2/15

First, find the probability of drawing a pink card first. There are 10 cards, and 4 of them are pink, so the probability is 4/10, which can be simplified to 2/5.

Now find the probability for the second card to be pink. There are now 9 cards, and 3 of them are pink, so the probability is 3/9, or 1/3.

Finally, multiply the probabilities together. First, multiply the numerators together. 2 * 1 = 2. Now, multiply the denominators together. 5 * 3 = 15. So, the final probability is 2/15

For this case we have the following equation:

[tex]3-2z = \frac {1} {10}[/tex]

We must find the value of z that represents the solution of the equation:

We follow the steps below:

We multiply by 10 on both sides of the equation:

[tex]10 (3-2z) = 1[/tex]

We apply distributive property to the terms of parentheses;

[tex]30-20z = 1[/tex]

We subtract 30 from both sides of the equation:

[tex]-20z = 1-30\\-20z = -29[/tex]

We divide between -20 on both sides of the equation:

[tex]z = \frac {-29} {- 20}\\z = \frac {29} {20}\\z = 1.45[/tex]

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 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.
