Answer:

30 um²

Step-by-step explanation:

BC = √5² - 4²

= √25 - 16

= √9

= 3 um

AC = 12 + 3 = 15 um

A = AC×BD/2

= 15×4/2

= 15×2

= 30 um²

Answer: [tex]g=(3d-2)^2-5[/tex]

Step-by-step explanation:

[tex]\sqrt{g+5}=3d-2[/tex]

To get rid of the square root, we can square both sides of the equation.

[tex](\sqrt{g+5})^2=(3d-2)^2[/tex]

[tex]g+5=(3d-2)^2[/tex]

Subtract 5

[tex]g+5-5=(3d-2)^2-5\\g=(3d-2)^2-5[/tex]

Answer:

the angle required for them to point their  camera to the horizontal should be at 61.66°

Step-by-step explanation:

Given that the base of the camera is 322 meters from the horizontal and the height is 597 meters.

We can use the tangent of the trigonometric equation.

tan θ = opposite / adjacent

tan θ = 597/322

tan θ = 1.854

θ = tan⁻¹ (1.854)

θ = 61.66°

Hence, the angle required for them to point their  camera to the horizontal should be at 61.66°

Answer:

Step-by-step explanation:

The position of the camera forms a right angle triangle. The horizontal distance from the base of the mountain represents the opposite side of the triangle while the height of the mountain represents the adjacent side of the triangle. To determine the angle, # that he should point his camera from the horizontal, we would apply the tangent trigonometric ratio which is expressed as

Tan # = opposite side/adjacent side

Tan# = 597/322 = 1.85

# = Tan^-1(1.85)

# = 61.61°

Answer:

Step-by-step explanation:

d = diameter = 12ft

r = d/2 = 12/2 = 6ft

Slant height = 13ft

Surface area of cone = π r 2 + π L r

Where L is the slant height of the cone π = 22/7

SA = 22/7×6×6+22/7×13×6

SA = 113.14+245.142

SA = 358.28ft^2

If one bundle of shingle covers 32 ft.²

Hence,358.28ft^2  = 358.28ft^2/32 ft.²

= 11.196

= 11.2 bundles

Answer:

s = 15

Step-by-step explanation:

Using the given information to solve for s, the work would look something like this:

s + 53 =g, g=68

s + 53 = 68 (Subtract 53 from both sides to get s by itself)

53 - 53 = 0, 68 - 53 = 15

s = 15

Therefore, s is equal to 15

Hope this helps! Have a good rest of your day!

Answer:

15

Step-by-step explanation:

This is very simple, first we write the equation, s+53=g, and plug 68 into "g", so now we have s+53=68. Subtract both sides, s+53-53=68-53, and this equals 15 years of age

Answer:

Step-by-step explanation:

Given the intensity, or loudness, of a sound  measured in decibels (dB), according to the equation [tex]I (dB)= 10log(\frac{I}{Io} )[/tex] where;

I is the intensity of a given sound and

[tex]Io[/tex] is the threshold of hearing intensity

To get I(dB) when [tex]I=10^{32} Io[/tex]

We will substitute the value of I = [tex]I=10^{32} Io[/tex] into the equation above to have;

[tex]I (dB)= 10log(\frac{10^{32}Io }{Io} )\\I(dB)=10log10^{32}\\ I(dB)=32*10log10\\[/tex]

Since log10 = 1;

[tex]I(dB)=32*10(1)\\I(dB)=320[/tex]

The intensity in decibel is 320 decibel

Answer:

Its D or 80

Step-by-step explanation:

I=10^8 (I subscript 0) can be written as I/I subscript 0, and you can plug that right into the log to get 80.

Answer:

V = 703.36 in³   (This matches answer option A.)

Step-by-step explanation:

This fish tank has a cylindrical shape.  The formula for the volume of a cylinder of radius r and height h is

V = (pi)(r²)(h).

We are told that h = 14 in and r = 4 in.  Using 3.14 for pi:

V = (3.14)(4 in)²(14 in) =

V = 703.36 in³   (This matches answer option A.)

Answer:

1. ∠A =  71.9°

2. ∠B =  62.9°

3. ∠C = 27.5°

Step-by-step explanation:

By using a calculator, we have;

cos A = 0.31

sin B = 0.89

tan C = 0.52

1. Therefore, ∠A = cos⁻¹(0.31), inputting the digits in the calculator and looking for the inverse sign, we have;

∠A = cos⁻¹(0.31) = 71.94° = 71.9° to the nearest tenth of a degree.

2. For sin B = 0.89, we have;

∠B = sin⁻¹0.89 = 62.873° ≈ 62.9° with the answer rounded to the nearest tenth of a degree.

3. Similarly, for tan C = 0.52, inputting the values in the calculator and pressing the tan⁻¹ button, we have;

∠C = tan⁻¹(0.52) = 27.474°, which is 27.5° rounded to the nearest tenth of a degree.

Answer:

12 inches

Step-by-step explanation:

I just took the unit test review on edge

Since the minor arc AB measures 9π inches, the length of the radius of circle C is equal to: B. 12 inches.

Given the following data:

Mathematically, the length of an arc formed by a circle is calculated by using this formula:

Arc length = rθ

Where:

Substituting the given parameters into the formula, we have:

9π = r × 3π/4

36π = 3πr

36 = 3r

r = 36/3

Radius, r = 12 inches.

0 = x2 - 9x + 20

Step-by-step explanation:

y + 5x = x² + 10     Simplify this equation

  - 5x   - 5x

y = x² - 5x + 10

Set both equations equal to each other since they both equal y

x² - 5x + 10 = 4x - 10

    -4x           - 4x

x² - 9x + 10 = -10

Answer:

The answers are;

a. None

b. None

c. Infinite

d. None

e. None

Step-by-step explanation:

The number of non congruent triangles that can be drawn depends on the uniqueness of the triangle

The parameters of a unique triangle are;

Knowing the Side Side Side (SSS)

Knowing the Side Angle Side (SAS)

Knowing the Angle Side Angle (ASA)

Knowing the Angle Angle Side (AAS)

However, knowing only the Side Side Angle it is possible to draw two non-congruent triangles

Therefore, considering each of the triangles gives;

a. Sides 7 inches, 8 in., and 16 in. which is of the form SSS hence the triangle is well defined and it is not possible to draw two non-congruent triangle with the provided properties

b. Similarly, the given triangle parameters are 4 in., 4 in., and 6 in. which is of the form SSS hence the triangle is well defined and it is not possible to draw two non-congruent triangle with the provided information

c. The parameters of the triangle given here are angles 30°, 60°, and 90° which is of the form Angle Angle Angle, or AAA for which the sides can be scaled to form an infinite number of non-congruent triangles

d. The parameters given are three angles measuring 120° which does not form a triangle as the sum of triangles in a triangle = 180°

Hence the number of non-congruent triangles that can be drawn in this case = 0

e. The parameters given are two angles measuring 45° and one side length of 10 in., hence the parameter is of the forms AAS or ASA hence the triangle is unique and it is not possible to draw two non-congruent triangle with the provided properties.
