graph the inequality on the axis below x+6y<6

The data in the table is an illustration of a quadratic equation, and the quadratic equation that models the data is (d) y = -0.15x² + 2x + 5.5

A quadratic model is represented as:

y = ax² + bx + c

Using the point (x,y) = (0,5.5);

We have:

a(0)² + b(0) + c = 5.5

This gives

c = 5.5

Substitute c = 5.5 in y = ax² + bx + c

y = ax² + bx + 5.5

Using the point (x,y) = (1,7.35);

We have:

a(1)² + b(1) + 5.5 = 7.35

This gives

a + b + 5.5 = 7.35

Subtract 5.5 from both sides

a + b = 1.85

Using the point (x,y) = (2, 8.9);

We have:

a(2)² + b(2) + 5.5 = 8.9

This gives

4a + 2b + 5.5 = 8.9

Subtract 5.5 from both sides

4a + 2b = 3.4

Divide through by 2

2a + b = 1.7

Subtract a + b = 1.85 from 2a + b = 1.7

2a - a + b - b = 1.7 - 1.85

This gives

a = -0.15

Substitute a = -0.15 in 2a + b = 1.7

-2 * 0.15 + b = 1.7

This gives

-0.3 + b = 1.7

Add 0.3 to both sides

b = 2

Substitute a = -0.15 and b = 2 in y = ax² + bx + 5.5

y = -0.15x² + 2x + 5.5

Hence, the quadratic equation that models the data in the table is (d) y = -0.15x² + 2x + 5.5

The percentage of youth that are category 10 to 12 is the quotient of  their frequency to the total frequency

55% of the actors are 10 to 12 years old

From the complete question, we have the following parameters

The percentage of youth in the age category 10 - 12 is then calculated as:

Percentage = Frequency of age category 10 - 12/Total frequency

This gives

Percentage = 22/40

Evaluate the quotient

Percentage = 55%

Hence, 55% of the actors are 10 to 12 years old

The best description of the resulting three-dimensional figure when the considered figure is revolved is: A cylinder with height 24 cm.

When a figure is revolved around some fixed axis, the whole three dimensional solid formed from the area that it swaps out is called solid of revolution.

Since no image is specified, we will work on the image attached below.

We can visualize and imagine that the horizontal line is still and just rotating on its place. The rectangle will revolve around, and therefore will swap out a cylindrical shape.

Since the length of the rectangle is 24 cm, and it is rotated on its length, so that will serve as height of the formed cylinder.

Thus, the best description of the resulting three-dimensional figure when the considered figure is revolved is: A cylinder with height 24 cm.

0.62% of the adult pandas weight over 250 pounds

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean)  / standard deviation

Given mean of 200 pounds and a standard deviation of 20 pounds.

For x > 250 pounds:

z = (250 - 200) / 20 = 2.5

P(z > 2.5) = 1 - P(z < 2.5) = 1 - 0.9938 = 0.62%

From the calculations, the number of whole trees that can be sold at $75,000 is 21 trees.

Density is defined a the mass per unit volume. Now we have the following;

Diameter = 50 cm or 0.5 m

height = 10 meters

volume = ?

Density of the cylinder = 380 Kg/m^3

Now;

We can get the volume from;

V = πr^2h

V = 3.142 * (0.5/2)^2 * 10

V = 1.96m^3

From;

D = m/V

m = DV

m = 1.96m^3 * 380 Kg/m^3

m = 744.8 Kg

If 1 Kg of wood is sold at $4. 75

744.8 Kg is sold at 744.8 Kg  *  $4. 75/  1 Kg

= $3537.8

Step-by-step explanation:

Using proportions, it is found that since 43% of the total amount is 129, 300 students were surveyed in total.

A proportion is a fraction of a total amount.

In this problem, since 57% of the students surveyed said their favorite color was blue, hence 100 - 57 = 43% said it was red, and this amount is of 129 students, hence:

0.43n = 129

n = 129/0.43.

n = 300.

If h⁻¹(x) is the inverse of h(x), then by definition of inverse function,

h(h⁻¹(x)) = x

Given that h(x) = 6∛(2x + 5) - 1, we have

h(h⁻¹(x)) = 6∛(2 h⁻¹(x) + 5) - 1 = x

Solve for h⁻¹(x) :

6∛(2 h⁻¹(x) + 5) - 1 = x

6∛(2 h⁻¹(x) + 5) = x + 1

∛(2 h⁻¹(x) + 5) = (x + 1)/6

[∛(2 h⁻¹(x) + 5)]³ = [(x + 1)/6]³

2 h⁻¹(x) + 5 = (x + 1)³/216

2 h⁻¹(x) = (x + 1)³/216 - 5
