Answer:

[tex] y = 2 5 0 ( 0 . 8 9 ) ^ x [/tex]

Initial value: 250

Decay

Decay rate: 11%

[tex] y = 4 0 ( 1.11 ) ^ x [/tex]

Initial value: 40

Growth

Growth rate: 11%

Step-by-step explanation:

The function we have on the left of the table is:

[tex] y = 2 5 0 ( 0 . 8 9 ) ^ x [/tex]

Initial value (when x = 0): [tex] y = 2 5 0 ( 0 . 8 9 ) ^ 0 [/tex]

y = 250 (initial value)

Growth or Decay: 0.89 < 1 so decay

Decay rate: (1 - 0.89) * 100 = 11%

Function on right side:

[tex] y = 4 0 ( 1.11 ) ^ x [/tex]

Initial value (when x = 0): [tex] y = 4 0 ( 1 . 1 1 ) ^ 0 [/tex]

y = 40 (initial value)

Growth or decay: 1.11 > 1 so growth

Growth rate: (1.11 - 1) * 100 = 11%

Answer:

16x² + 56x + 49

Step-by-step explanation:

First, expand:

(4x + 7)² = (4x + 7)(4x + 7)

Follow the FOIL method. FOIL = First, Outside, Inside, Last.

(4x)(4x) = 16x²

(4x)(7) = 28x

(7)(4x) = 28x

(7)(7) = 49

16x² + 28x + 28x + 49

Combine like terms:

16x² + (28x + 28x) + 49

16x² + (56x) + 49

16x² + 56x + 49 is your answer.

Combine like terms:

4x - 7 = 20 - 5x

Isolate Variable

-x = 13

-1(-x) = -1(13)

x = -13

Answer: [tex]x=3[/tex]

Step-by-step explanation:

You need to apply Distributive property on the left side of the equation:

[tex]2(4-3x)+5(2x-3)=20-5x\\\\8-6x+10x-15=20-5x[/tex]

Now you must add the like terms on the left side of the equation:

[tex]-7+4x=20-5x[/tex]

Add [tex]5x[/tex] to both sides:

[tex]-7+4x+5x=20-5x+5x\\\\-7+9x=20[/tex]

Add 7 to boht sides of the equation:

[tex]-7+9x+7=20+7\\\\9x=27[/tex]

And finally, divide both sides by 9:

[tex]\frac{9x}{9}=\frac{27}{9}\\\\x=3[/tex]

Anytime you have zero as a possible answer, you have to consider it carefully. Part of the whole number system is 0. They go up from there. No fraction is a whole number. No decimal is a whole number except those that are equal to  a whole number.

The rest are all decimals so they are not whole numbers. Note I just noticed that the other numbers have periods after the choice. There are other whole numbers there if that is the case.

C D E and F are all whole numbers if that is a period after their choice letters.

Final answer:

The volume of the core of the golf ball from Great Drive, with a diameter of 1.68 inches, is approximately 2.48 cubic inches. This is calculated using the formula for the volume of a sphere with the radius derived from the given diameter. The correct answer is 2.48 in³, which is option A.

Explanation:

The volume of a sphere is given by the formula V = (4/3) πr3, where π is pi (approximately 3.14159) and r is the sphere's radius. The diameter of the golf ball's core is given as 1.68 inches, so the radius is half of that, which is 0.84 inches. Plugging this into the formula gives us:

V = (4/3) π (0.84 inches)3 = (4/3) π (0.84 inches × 0.84 inches × 0.84 inches)

Doing the math, we find that:

V ≈ (4/3) π (0.592704 inches3) ≈ 2.48 in3

Therefore, the volume of the core of the ball rounded to the nearest hundredth is 2.48 cubic inches.

The correct answer is option A.

Answer:

x=2                x=-3

Step-by-step explanation:

4x2+3x=24-x

Subtract 24 from each side

4x^2 +3x -24 = 24-24 -x

4x^2 +3x -24 = -x

Add x to each side

4x^2 +3x+x -24 = -x+x

4x^2 +4x -24 = 0

Factor out a 4

4(x^2 +x -6) = 0

Divide by 4

x^2 +x -6 =0

Factor

What 2 numbers multiply to -6 and add to 1

-2*3 = -6

-2+3 =1

(x-2) (x+3) =0

Using the zero product property

x-2 =0            x+3 =0

x-2+2=0+2    x+3-3=0-3

x=2                x=-3

Answer:x=-3 , x = 2

Step-by-step explanation:

First move the expression ( 24-x) to the left.

This gives us 4x^2+3x+24-x.

Collect the like terms which gives us 4x^2+4x+24

4x^2+4x-24 = 0.  Divide both sides by 4.

x^2 + x-6 = 0

Factorise the expression so you get (x+3)(x-2)=0

Solve the equations x+3 = 0 and x-2=0

The final solutions are x=-3 and x=2.

Answer:

The standard deviation of the age is 6.16

Step-by-step explanation:

* Lets talk about the variance and the standard deviation

- The variance is the measure of how much values in a set of data are

 likely to differ from the mean value of the same data

- The steps to find the variance are:

1- Find the mean of the data  

2- Subtract the mean from each value and square the answer

3- Add all of these squared answer and divide the sum by the number

  of the values

- The answer of the step 3 is The variance (σ²)

- The standard deviation (σ) is the square root of the variance

* Now lets solve the problem

∵ The variance of the ages of the people who attended a rock

  concert is 38

∴ σ² = 38

∵ The standard deviation is the square root of the variance

∴ σ = √38 = 6.16

* The standard deviation of the age is 6.16

Answer:

[tex]\sigma=6.16[/tex]

Step-by-step explanation:

By definition, the variance V of a population is defined as:

[tex]V = \sigma^2[/tex]

Where [tex]\sigma[/tex] is the standard deviation

We know that [tex]V = 38[/tex], then we can solve the equation for the standard deviation [tex]\sigma[/tex]

[tex]38 = \sigma^2[/tex]

[tex]\sigma^2=38[/tex]

[tex]\sigma=\sqrt{38}[/tex]

[tex]\sigma=6.16[/tex]

Finally  the standard deviation is: [tex]\sigma=6.16[/tex]

6x^3-3x^3y^2

Step-by-step explanation:

6x^3+\left(-3x^3y^2\right)

6x^3+\left(-3x^3y^2\right)=6x^3-3x^3y^2

=6x^3-3x^3y^2

the answer is 3x^3(2-y^2).

6x^3 + (-3x^3y^2) =

6x^3 - 3x^3y^2 =

3x^3(2-y^2)

For this case we have that the point-slope equation of a line is given by:

[tex](y-y_ {0}) = m (x-x_ {0})[/tex]

Where:

m: It's the slope

[tex](x_ {0}, y_ {0}):[/tex] It is a point

We have as data that:

[tex](x_ {0}, y_ {0}): (- 2, -7)\\m = - \frac {3} {2}[/tex]

We replace:

[tex](y - (- 7)) = - \frac {3} {2} (x - (- 2))\\(y + 7) = - \frac {3} {2} (x + 2)[/tex]

Answer:[tex](y + 7) = - \frac {3} {2} (x + 2)[/tex]

g^5h^2

Step-by-step explanation:

12g^5h^4, g^5h^2

This is one way of doing it. Break down every number and every variable into a product of the simplest factors. Then see how many of each factor appear in both monomials.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

So far you see every single prime factor of each monomial.

Now I will mark the ones that are present in both. Those are the common factors.

12g^5h^4 = 2 * 2 * 3 * g * g * g * g * g * h * h * h * h

g^5h^2 = g * g * g * g * g * h * h

The greatest common factor is the product of all the factors that appear in both monomials.

GCF = g * g * g * g * g * h * h = g^5h^2

Answer:

32028.8 ounces

Step-by-step explanation:

We are given that there are 908 kilograms of of trial mix are in a bag and we are to find the number of ounces of the same amout of mix in the bag.

For that, we will use the ratio method.

We know that, 1 kg = 35.274, so:

[tex] \frac { 1 k g }{908kg} =\frac{35.274 oz}{x}[/tex]

[tex]x=32028.8[/tex]

Therefore, there are 32028.8 ounces of mix in the bag.

Final answer:

To find the amount of trail mix in ounces from 0.908 kilograms, convert the weight to grams and then to ounces using the conversion of 1 oz = 28.35 g, resulting in approximately 32.012 ounces of trail mix.

Explanation:

To convert the weight of the trail mix from kilograms to ounces, we need to use the conversion factor: 1 oz is produced by a mass of 28.35 g. First, convert the kilograms to grams by multiplying by 1000, because there are 1000 grams in a kilogram. Then, once we have the weight in grams, we can convert grams to ounces using the provided conversion rate.

Here's the calculation step by step:

Convert kilograms to grams: 0.908 kg × 1000 = 908 grams.

Convert grams to ounces: 908 g ÷ 28.35 g/oz = 32.012 ounces (rounded to three decimal places).

Thus, a bag that weighs 0.908 kilograms contains approximately 32.012 ounces of trail mix.

Starting from the fact that the equation of the point-slope form of a line is given by:

[tex](y-y_ {1}) = m (x-x_ {1})[/tex]

If we compare the standard equation with Harold's, we see that the slope of the line is [tex]m = 3.[/tex]

Answer:

Step-by-step explanation:

The median is the middle, since the amount of data is an even number we need to add up the third number and fourth number. These are 3 and 5 respectively. Adding these up gives up 8. Dividing this by 2 is 4.

The sum of all the angles of a triangle is 180 degrees. To solve for y you can make a formula of the sum of the angles equal to 180 like so...

y + y + 60 = 180

Now you must combine like terms. This means that first numbers with the same variables (y) must be combined...

y + y + 60 = 180

y + y = 2y

2y + 60 = 180

Now bring 60 to the left side by subtracting 60 to both sides (what you do on one side you must do to the other). Since 60 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

2y + 60 - 60 = 180 - 60

2y + 0 = 120

2y = 120

Next divide 2 to both sides to finish isolating y. Since 2 is being multiplied by y, division (the opposite of multiplication) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.

2y / 2 = 120 / 2

y = 60

The inequality x - 7 > -20 is solved by adding 7 to both sides, resulting in x > -13. The graph of this inequality has an open circle at -13 with shading to the right.

To solve the inequality x - 7 > -20, you want to isolate the variable x on one side. You can do this by adding 7 to both sides of the inequality:

x - 7 + 7 > -20 + 7

x > -13

So, the solution to the inequality is x > -13. To graph this solution on a number line, you would draw an open circle at -13 and shade to the right, indicating that x can be any value greater than -13 but not including -13 itself.

The y-intercept is where it crosses the y-axis. That means the x-coordinate is zero there. So this point represents how much it cost before any hours are applied. This is also known as the initial cost.
