The example of shapes that was studied under the Math accelerated chapter 12 workbook is The volume of the prism is shown as 61.6in³. What is the height of the prism?

The Glencoe Math Accelerated is known to be a comprehensive robust text that has been set up to support the teachers teaching skills and styles and also to address the needs of your students.

To solve for the height of the prison. The formula is

V = lwh

V = 61.6

V= 8 x 2.2 x h

H = 61.6/17.6

H= 17.6h/17.6

H = 3.5in³

Based on the calculations, the radius of this circle with the given equation is equal to 5 units.

Given the following data:

Mathematically, the standard form of the equation of a circle is given by;

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where:

Expanding the equation, we have:

[tex]x^2+y^2-2hx-2ky+(h^2+k^2-r^2)=0\\\\r=\sqrt{h^2+k^2}[/tex]

Comparing the terms, we have:

[tex]-2hx = 8x\\\\-2h=8\\\\h=\frac{8}{-2}[/tex]

h = -4

[tex]-2ky = -6y\\\\-2k=6\\\\k=\frac{6}{-2}[/tex]

k = 3.

Now, we can determine the radius:

[tex]r=\sqrt{-4^2+3^2}\\\\r=\sqrt{16+9} \\\\r=\sqrt{25}[/tex]

r = 5 units.

The probability of drawing three aces in a row is the likelihood of drawing three aces

The probability of drawing three aces in a row is 0.000181

In a standard deck of 52 cards, there are 4 aces.

Given that the selection is without replacement; then we have the following selections:

The probability is then calculated as;

[tex]P = \frac{4}{52} * \frac{3}{51} * \frac{2}{50}[/tex]

Evaluate the products

[tex]P = 0.00018099547[/tex]

To capture his feet and head, the camera will need to be moved at least one foot backward. This is an Angles of Elevation and Depression theorem exercise.

The angle of elevation is the angle between the line of sight and the horizontal line when an observer looks up. While the Angle of Depression refers to the angle that is formed when the observer looks down.

The formulas are given as:

tan θ = y/x  ⇒      θ = tan -1 (y/x).  

Let us assume that x is the distance in feet that the tripod must be moved back.

Recall that the angle of depression and elevation as given in the question (full version attached) is 20°

The height of the Tripod is 4 feet, at a distance of 10 feet, therefore,

tan (20°) * (10 + x) = 4

⇒

x =4/tan (20°)-10

x= 4/(10.989909678 - 10)

x = 0.9899

x ≈ 1 feet.

Hence the camera must be moved back about 1 feet to capture Geroge..

To determine the height, we make use of the following tangent trigonometry ratio

[tex]\tan(68.5) = \frac{h}{54.0}[/tex]

Where:

h represents the height of the flagpole.

So, we have:

[tex]h = 54.0 * \tan(68.5)[/tex]

From the figure, we have:

MK = 61

LN = 111

So, we have:

MPK = 0.5 * (61 + 111)

The sum of the first ten terms of the given sequence when approximated to four decimal places is; 9.6758

We are given the formula for the sequence as;

aₙ = 1 + (⁻¹/₂)ⁿ

Thus;

First term; a₁ = 1 + (⁻¹/₂)¹ = 0.5

a₂ = 1 + (⁻¹/₂)² = 1.25

a₃ = 1 + (⁻¹/₂)³ = 0.875

a₄ = 1 + (⁻¹/₂)⁴ = 1.0625

Fifth term; a₅ = 1 + (⁻¹/₂)⁵ = 0.96875

a₆ = 1 + (⁻¹/₂)⁶ = 1.01563

a₇ = 1 + (⁻¹/₂)⁷ = 0.99219

a₈ =  1 + (⁻¹/₂)⁸ = 1.00391

a₉ = 1 + (⁻¹/₂)⁹ =  0.99805

Answer:

Explanation:

the following formula is used to find the volume of a cone

V - volume = πr²h/3

where π = 3.14, r - radius and h - height

the height hasnt been directly given

we can find height using Pythogoras theorem for the right angled triangle given

4² + h² = 5²

16 + h² = 25

h² = 25 - 9

h² = 9

h = 3

height = 3

diameter is 4, therefore radius - diameter / 2 = 4/ 2 = 2

radius = 2

substituting values in the volume equation

V = 3.14 x 2² x 3 /3

= 12.56

volume is 12.56 cubic units
