The equation shows that the point total in the 10th level is predicted to be 514.4.

The equation given is: y= 48.2x + 32.4

where y is the point total and x is the level.

In order to predict the point total in the 10th level, I will substitute x=10 into the equation:

y=48.2(10) + 32.4 = 482 + 32.4 = 514.4

Therefore, the point total in the 10th level is predicted to be 514.4.

The interior angles of the trapezium is as follows:

The sum of interior angles in a quadrilateral is 360 degrees. Therefore, the diagram above is a trapezium with 4 sides.

Let's find the measure of each interior angles

2x + 2x + 20 + 2x - 10 + 3x - 10 = 360

9x  = 360

divide both sides by 9

x = 360 / 9

x = 40

Therefore, each interior angles is as follows:

2x = 2(40) = 80 degrees

2x + 20 = 2(40) + 20 = 100 degrees

2x - 10 = 2(40) - 10 = 70 degrees

The volume of the triangular prism is V = 18ft³

The volume of the prism is equal to the area of the triangular face, times the length of the prism, which is 9ft.

Remember that the area of a triangle of base B and height H is:

A = B*H/2

Here we can see that the base is 2ft and the height is 2ft, then the area of the triangular face is:

A = 2ft*2ft/2 = 2ft²

Answer:

The distance between Garland and Mansfield on the map is 15 inches.

Step-by-step explanation:

On Giana's map of Texas, the scale is 1 inch = 3.5 miles. To determine the distance between Garland and Mansfield on the map, we can use the scale to find the corresponding measurement. Given that the actual distance between these two cities is 52.5 miles, we can set up a proportion:

1 inch / 3.5 miles = x inches / 52.5 miles

Cross-multiplying, we have:

3.5 miles * x inches = 1 inch * 52.5 miles

3.5x = 52.5

Dividing both sides by 3.5, we find:

x = 15

Therefore, the distance between Garland and Mansfield on the map is 15 inches.

The surface area of the cylinder has a radius of 8cm and a height of 10 cm is 502.4 square centimeters.

We know that,

In geometry, a cylinder is one of the basic 3d shapes with two parallel circular bases at a distance. A curving surface connects the two circular bases at a predetermined distance from the centre. The axis of the cylinder is the line segment connecting the centres of two circular bases. The height of the cylinder is defined as the distance between the two circular bases. One real-world example of a cylinder is an LPG gas-cylinder.

The surface area of this cylinder is defined as the product of the radius of the base and the height of the cylinder.

The surface area of this cylinder = (2π x r)h

We have given a radius of the base is 8 cm and the height of the cylinder is 10 cm.

The surface area of this cylinder = (2π x r)h

= (2π x 8)10

= (50.24)10

= 502.4

Thus, The surface area of the cylinder has a radius of 8cm and a height of 10 cm is 502.4 square centimeters.

Answer:

To make a box-and-whisker plot, we first need to order the data from smallest to largest:

4, 5, 6, 10, 15, 16, 21

Next, we can find the median, which is the middle value of the ordered data set. In this case, the median is 10.

Then, we can find the lower quartile (Q1) and the upper quartile (Q3). The lower quartile is the median of the lower half of the data set, and the upper quartile is the median of the upper half of the data set. To find Q1 and Q3, we can split the data set into two halves:

4, 5, 6, 10 and 15, 16, 21

The median of the lower half is (5+6)/2 = 5.5, and the median of the upper half is (16+21)/2 = 18.5. Therefore, Q1 = 5.5 and Q3 = 18.5.

Now we can draw the box-and-whisker plot. The box represents the middle 50% of the data, with the bottom of the box at Q1 (5.5), the top of the box at Q3 (18.5), and the line inside the box at the median (10). The whiskers extend from the box to the smallest and largest values inthe data set that are not outliers. To determine whether there are outliers, we can use the following formula:

Outlier = Q1 - 1.5 * (Q3 - Q1) or Q3 + 1.5 * (Q3 - Q1)

Plugging in the values, we get:

Outlier = 5.5 - 1.5 * (18.5 - 5.5) = -13.25 or Outlier = 18.5 + 1.5 * (18.5 - 5.5) = 37.25

Since there are no values in the data set that are less than -13.25 or greater than 37.25, there are no outliers.

Therefore, the box-and-whisker plot for the given data is:

            |       4

     ___|___

    |              |

    |              |

    |      15.5 |------

    |       |      |

     ___|___

            |       21

The box spans from Q1 (5.5) to Q3 (18.5), with the median line inside the box at 10. The whiskers extend from the box to the minimum value of 4 and the maximum value of 21, since there are no outliers.

The exponential value equation is A = 1/√x = 1/x^(-1/2)

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

A = x ^ ( 1/6 ) / x ^ ( 2/3 )

The value of side TS is,

⇒ TS = 28

First, we are going to divide the figure and named new points X and Y as:

Now, we know that TS is the sum of TX and XS.

TS = TX + XS

Additionally, TX has the same length of HJ, so:

TX = HJ = 14

Now, we want to know the length of YK, and we can calculate it using the following equation:

LK = LY + YK

LY = HJ,

so, LY = 14

And, 42 = 14 + YK

42 - 14 = YK

28 = YK

Finally, since T and S are midpoints, the length of XS is the half of the length of YK. It means that XS is:

XS = YK/2

XS = 28/2

XS = 14

Therefore, TS is equal to:

TS = TX + XS

TS = 14 + 14

   The solution to the system of equations is x = 1,y = -1 by using the elimination method.

  To solve the system of equations using the elimination method, we'll eliminate one variable by adding or subtracting the equations. Here's how:

  Multiply the first equation by 2 to make the coefficients of y in both equations opposite each other:

Equation 1: 2(y + 2x) = 2(1) => 2y + 4x = 2

  Rewrite the second equation as:

Equation 2: 3x - 2y = 5

  Now, we can add the modified Equation 1 to Equation 2 to eliminate y:

(2y + 4x) + (3x - 2y) = 2 + 5

  Simplifying, we get:

4x + 3x = 7

7x = 7

  Divide both sides of the equation by 7 to solve for x:

x = 7/7

x = 1

  Substitute the value of x into either of the original equations. Let's use the first equation:

y + 2(1) = 1

y + 2 = 1

  Subtract two from both sides of the equation to solve for y:

y = 1 - 2

y = -1

The solution for X is X ≈ [tex]tan^{(-1)(0.7429)[/tex], which is approximately 0.6619 radians or approximately 37.89 degrees.

Given: 1 secX + 3 = cosX + tanX (2 + sinX)

To simplify the equation, let's express secX and tanX in terms of sinX and cosX:

1/cosX + 3 = cosX + sinX/cosX (2 + sinX)

Now, multiply both sides by cosX to eliminate the denominators:

[tex]1 + 3cosX = cos^2X + sinX(2 + sinX)[/tex]

Expanding the equation:

[tex]1 + 3cosX = cos^2X + 2sinX + sin^2X[/tex]

Since [tex]sin^2X + cos^2X[/tex] equals 1 (based on the Pythagorean identity), we can substitute it into the equation:

[tex]1 + 3cosX = 1 + 2sinX + sin^2X[/tex]

Rearranging the terms:

[tex]3cosX = 2sinX + sin^2X[/tex]

Now, let's express cosX in terms of sinX using the Pythagorean identity:

cosX = √(1 - [tex]sin^2X[/tex])

Substituting this into the equation:

3√(1 - [tex]sin^2X) = 2sinX + sin^2X[/tex]

Squaring both sides to eliminate the square root:

[tex]9(1 - sin^2X) = (2sinX + sin^2X)^2[/tex]

Expanding the right side:

[tex]9(1 - sin^2X) = (2sinX)^2 + 2(2sinX)(sin^2X) + (sin^2X)^2\\9 - 9sin^2X = 4sin^2X + 4sin^3X + sin^4X[/tex]

Rearranging the terms:

[tex]sin^4X + 4sin^3X + 4sin^2X + 9sin^2X - 9 = 0[/tex]

Combining like terms:

[tex]sin^4X + 4sin^3X + 13sin^2X - 9 = 0[/tex]

Unfortunately, this equation does not have a simple algebraic solution. It needs to be solved numerically or graphically. Using numerical methods or a graphing calculator, we can find that one solution to this equation is sinX ≈ 0.7429.

Taking the inverse tangent (arctan) of both sides, we have:

X = arctan(0.7429)
